WCSJ2013 in Helsinki, a photo-tour

Flying directly from SciFoo in California to WCSJ2013 in Helsinki, Finland is a pretty long trip that requires a pretty big airplane. Those of you who know me well, know I am obsessed with airplanes, am an addict of FlightAlert, choose JetBlue on domestic flights in order to continuously monitor flight statistics, and my first requirement when someone else is booking my flights is “the biggest airplane you can get”. So I was quite pleased to be riding on this big bird, the original Jumbo Jet:

What I really liked, though, was something that is apparently banned on US air carriers, but both of Finnair flights (to and from London to Helsinki) had – a cockpit cam! While the screen shows many more different flight stats than JetBlue does, and one can also watch the view from a camera facing straight down (which is really nice when approaching the Land of 1000 Lakes), during the last few minutes of flight, during landing, everyone’s screen is automatically turned on to the cockpit cam. It feels like playing a video game, piloting the airplane down onto the runway!

They eat horses, don’t they?

“Behave, or I’ll send you to Italy!”.

That’s a strange threat! Wouldn’t it be wonderful to go there to visit the wine country, see the art in Florence, learn some history in Rome, and enjoy the Adriatic beaches?

Not if you hear the above and you are a horse! Especially if you were a horse back in the day when I used to ride in my now-extinct homeland of Yugoslavia.

With total number of horses in the country small and dwindling after the cavalry was disbanded in 1948, with fast urbanization of the country reducing the number of horses working the fields, and before equestrian sports started taking off again in the late 1980s, there was no need for a dedicated horse slaughterhouse. Occasionally a really urgent case would be slaughtered in a cattle slaughterhouse. A horse in agony after an injury would be killed on the spot (e.g., on the racetrack) and its meat donated to the perennially strapped-for-cash Belgrade Zoo for lions and other carnivores, But most horses at the end of their lives ended up on trucks headed to the meat market of Italy (and probably a few also to Austria – but I don’t have access to any documents, just what everyone in the horse business at the time knew).

With all the horse meat ending up in Italy, there was not much left for domestic consumption. Thus whole generations grew up without ever tasting it. The culture gradually changed. A horse butcher had a store in Belgrade for about a decade in the 1960s, but had to close due to low demand. Later, in mid-1980s, another entrepreneurial butcher opened a horse-meat store, this time promoting it as a delicacy rather than utilitarian, cheap alternative to beef. That store did not last long, either.

While there is no taboo against eating horse in the Balkans, there are definitely cultural forces that prevent it from being as popular as it is for its neighbors to the West, And those forces are divided by generations.

According to the elders, especially those with clear memories of World War II, horse meat was a poor man’s food, only to be consumed in times of war or famine. If you can afford beef, pork, lamb and chicken, why should you stoop so low as to eat the tough, acidic horse meat?

On the other hand, youngsters saw horses in a much less utilitarian way. They did not remember thousands of cavalry horses, cart horses, and draft horses filling the countryside. They did not remember poverty and hunger. Every horse they met had a name, be it a nice riding school pony, or a stunningly beautiful sports horse.

Obviously, neither of the two age groups could be easily persuaded that horse meat is a delicacy.

I saw that generational divide myself one day, back in the 1980s. We grilled some horse steaks…at the barn, right after we finished riding, grooming and petting our horses. There were horses inside, happily munching their oats in their stalls. There were other horses outside, sliced and roasting on the grill. How conflicted everyone’s feelings were!

But that was an excellent opportunity for all of us to discuss and debate the ethical, utilitarian, economic, nutritional, ecological and other angles of horse consumption. Why older people found it easier to eat the meat than the younger folk? Why was it easier for men than for women? Why some found it delicious, while others hated its texture and taste? Many of the young, pony-obsessed girls wouldn’t touch it, while younger boys gave it a try despite obvious disgust.

In the end, it all came down to names. You cannot eat an animal whose name you knew when it was alive. Name gives it a personality. An animal whose name you know is also an animal you know well – its looks and behavior and personality. It’s a friend. Friends don’t eat friends.

The steaks we had came from a horse we knew nothing about. Not the name, not age, sex, breed, color, anything. Perhaps the previous owner really loved that horse, cried when loading it onto the slaughterhouse truck. Just like one day, certainly, someone in Italy was going to eat the flesh of our horses we loved, and could do it because of not knowing those horses personally.

But by buying and eating that horse’s meat, we helped that previous owner recover some of the financial loss. Perhaps it was a farmer who lost a horse essential for working his farm. Without taking the meat price for the old horse, the farmer would not be able to buy a new horse, and would not be able to work the farm and feed his family. The circle of life would have been broken, both the human one and the equine one.

That was the economy of individual horse ownership by regular people. Of course, if you are rich or live in a rich country, and if you can afford to keep all your horses out on pastures until they die the natural death, by all means do that. But most people cannot afford that. And yet they need to have horses for their livelihoods. Eating horse meat is an essential part of such an economy.

I can attest that this statement is true.

I can attest that this statement is true.

But then it got tricky. The problem became more complex. After all, it is relatively easy for an individual to decide not to eat horse meat because of ethical concerns. But that is the meat of a dead horse who died in order to provide that meat. So, how do you try to use ethical considerations to explain why you refuse to eat meat of the horse who is still alive? I am talking about marinated, delicious testicles of the stallion who is still prancing out in the paddock. In a country where offal is a perfectly normal part of everyday cuisine, and one can order sweetbreads in any decent restaurant. No harm was done to any animal. So, why not eat it? Not an easy question to answer. And it’s pretty obvious that the answer is not rooted in ethics, economics, ecology, nutrition or health concerns. It is psychological and aesthetic, thus it is rooted in culture.

And this is where we switch gears, as we need to start comparing cultures, in this case Balkans with America.

“Behaving or not, you’re going to Mexico!”

The question “shall we eat horse meat?” is coupled with the related question “shall we slaughter horses?”. In both countries, most of the horse slaughter (and consumption) is outsourced to other countries (Italy in the case of the Balkans, Mexico in the case of USA). Yet the attitudes are different. There, if there were more horses and there was more appetite for meat, there would be horse slaughter in place with almost nobody’s objection. Without too much emotional opposition to eating horses, economic forces would be allowed to dictate what happens on the ground.

Here, there is an overabundance of horses, but because there is no appetite for meat at all, slaughtering horses is considered a very bad idea. Hence such outcry when the slaughter of horses was recently made legal again after a long time (and opening a slaughterhouse is fraught with difficulties).

If unicorns were easier to catch, they would be a staple diet in at least some cultures.

The shift in culture that I started observing in the 1980s there, already occurred much earlier here in the States. Horses are still used in agriculture there, especially in more mountainous regions where tractors are ineffective and uneconomical. Many small farmers cannot afford tractors, or have too little land to need one. Older people still remember the life on the farm, and even kids have seen horses working in the field. The movement from country to city happened too recently.

Here, agriculture has long ago moved from small farmers to gigantic agribusiness. Very few people have any personal experience with a horse working the land. Most horses are used for pleasure and sport – they have names and are treated as pets, rather than as beasts of burden.

Also, there is an overproduction of horses here. So many horses are bred, often of poor quality, that many never get to be ridden at all – they go straight to Mexico while still young. It is not that just old, sick or lame horses get slaughtered, it’s healthy foals! It’s not just a natural circle of life, it’s production of horses directly for slaughter.

Then, there is the issue of food safety. There is a reason Europe does not allow import of American horsemeat, no matter how much demand there may be there (and demand is dropping there as well). One never knows if the meat came from a racehorse (or if it’s horse meat at all). The rules for drug use (from steroids to painkillers) in racehorses in the USA are so lax compared to other countries, that it is almost certain that the meat of an American racehorse is unfit for human consumption. And how can one know if the steak or sausage came from a draft horse or a racehorse? With eating horse in America being potentially dangerous, it’s not strange that people don’t do it, and the cultural tradition of eating horses quickly dies out. If your parents never ate horse meat, you won’t either. Cultural food habits start at home.

But there are other reasons why American culture is so strongly against eating (and thus slaughtering) horses. I vaguely alluded to some of those already, but now need to be more explicit. And for this, we need to go back to the old master, anthropologist Marshall Sahlins and his 1976 essay La Pensee Bourgeoise: Western Society as Culture, in which he takes a close look as to why Americans eat cows and pigs, but don’t eat horses and dogs.

Manly Men in the Feed Lot.

True, “in most parts of the world, people are grateful to eat whatever is available to them.” Vast areas of the planet have scant vegetation. Plant agriculture is impossible due to poor soil. People need and want to live there anyway, at least as nomads if not settlers, but cannot sustain themselves on an occasional root or berry. They have to carry their food with them, but that also takes up energy. So the best way to survive in such harsh environments is to have the food walk along with them. Cattle, goats, sheep, camels, donkeys, mules, asses and yes, horses, are the sources of daily nourisment, both meat and dairy.

In places of plenty, in times of plenty, one can afford to have culture, rather than necessity, dictate what foods are deemed OK and what foods are not:

Yet the point is not only of consuming interest; the productive relation of American society to its own and the world environment is organized by specific valuations of edibility and inedibility, themselves qualitative and in no way justifiable by biological, ecological, or economic advantage.

There is no nutritional reason not to eat horse. If anything, horse meat may have some advantages over beef. If production of horse meat was a viable, large industry due to high demand, it would have similar environmental impact as beef industry has now, and the economics would be the same as well. Low demand is due to culture, which determines even how food taste is perceived. It is not surprising that food preferences then become deeply ingrained, and offers of locally unusual foods elicit strong negative responses based entirely on emotions, rather than rational calculations. So even during times of crisis and famine, those cultural and emotional obstacles prevent the population from taking advantage of available food sources, regardless of governmental, corporate, scientific or media efforts to help enlighten the population about it. The angry reactions are based entirely on cultural norms and emotional sense of disgust. Sahlins uses this example from the Honolulu Advertiser of 15 April 1973:

“Horses are to be loved and ridden,” Gallagher said. “In other words, horses are shown affection, where cattle that are raised for beef … they’ve never had someone pet them or brush them, or anything like that. To buy someone’s horse up and slaughter it, that, I just don’t see it. “

Sahlins again:

In a crisis, the contradictions of the system reveal themselves. During the meteoric inflation of food prices in the spring of 1973, American capitalism did not fall apart-quite the contrary; but the cleavages in the food system did surface. Responsible government officials suggested that the people might be well-advised to buy the cheaper cuts of meat such as kidneys, heart, or entrails-after all, they are just as nutritious as hamburger. To Americans, this particular suggestion made Marie Antoinette seem like a model of compassion (see fig. 10). The reason for the disgust seems to go to the same logic as greeted certain unsavory attempts to substitute horsemeat for beef during the same period.

When I came to the States, I understood that I would not be eating horse here at all. Which is fine with me – I tried a steak once and a sausage once, and while they were OK, I can totally live without them. But when we castrated a couple of colts at the barn, none of the whites would touch the testicles. But they were expertly prepared by an African American friend and we ate them with great appreciation.

As I wrote at length a few years ago, one of the specifics of American cuisine, due to culture, lies in its history. When we talk about Balkans food preferences, we are covering pretty much everyone who lives there – the class divisions and cultural divisions were always quite miniscule there. But when we talk about American food preferences, we tend to forget a big chunk of American culture. Whites prefer beef to other species, and will almost universally not eat offal. But there is a whole parallel culture, often unmentioned. The soul food, the Southern food, all the offal and innards and roadkill and strange foods that were cooked, and recipes perfected into delicacies by generations of African Americans, descendant of slaves who fixed steaks for the white masters and learned how to utilize everything else from the slaughtered animals. They have no problem with offal – or horse – as that is an intergral component of that subdivision of the American culture. Sahlins:

The poorer people buy the cheaper cuts, cheaper because they are socially inferior meats. But poverty is in the first place ethnically and racially encoded. Blacks and whites enter differentially into the American labor market, their participation ordered by an invidious distinction of relative “civilization.” Black is in American society as the savage among us, objective nature in culture itself. Yet then, by virtue of the ensuing distribution of income, the “inferiority” of blacks is realized also as a culinary defilement. “Soul food” may be made a virtue. But only as the negation of a general logic in which cultural degradation is confirmed by dietary preferences akin to cannibalism, even as this metaphorical attribute of the food is confirmed by the status of those who prefer it. I would not invoke “the so-called totemism” merely in casual analogy to the pensee sauvage. True that Levi-Strauss writes as if totemism had retreated in our society to a few marginal resorts or occasional practices (I 963a; 1966). And fair enough-in the sense that the “totemic operator,” articulating differences in the cultural series to differences in natural species, is no longer a main architecture of the cultural system. But one must wonder whether it has not been replaced by species and varieties of manufactured objects, which like totemic categories have the power of making even the demarcation of their individual owners a procedure of social classification. (My colleague Milton Singer suggests that what Freud said of national differentiation might well be generalized to capitalism, that it is narcissism in respect of minor differences.)

Marshall Sahlins then delves into the question of words and names. As he reminds us, Red Queen said, “It isn’t etiquette to cut anybody you’ve been introduced to.” Horses (and dogs) have names. Most cows (and pigs) don’t.

Muscles of accepted food animals have cute monikers that hide what parts of the animal and which animal they came from. There is beef and pork and mutton. There are steaks and t-bones and round and chuck. But un-acceptable species don’t have such cutesy names for their muscles. Horse meat is called horsemeat. Dog’s would be dog-meat. Nothing to hide. Likewise, names for innards are not cutesy, hiding the obvious source: liver is liver, tongue is tongue, kidneys are kidney (though intestines become tripe, and testicles, probably due to puritanism, become whitebreads). Sahlins again:

Edibility is inversely related to humanity. The same holds in the preferences and common designations applied to edible portions of the animal. Americans frame a categorical distinction between the “inner” and “outer” parts which represents to them the same principle of relation to humanity, metaphorically extended. The organic nature of the flesh (muscle and fat) is at once disguised and its preferability indicated by the general term “meat,” and again by particular conventions such as “roast,” “steak,” “chops,” or “chuck”; whereas the internal organs are frankly known as such (or as “innards”), and more specifically as “heart,” “tongue,” “kidney,” and so on-except as they are euphemistically transformed by the process of preparation into such products as “sweetbreads.”The internal and external parts, in other words, are respectively assimilated to and distinguished from parts of the human body-on the same model as we conceive our “innermost selves” as our “true selves”-and the two categories are accordingly ranked as more or less fit for human consumption. The distinction between “inner” and “outer” thus duplicates within the animal the differentiation drawn between edible and tabu species, the whole making up a single logic on two planes with the consistent implication of a prohibition on cannibalism. It is this symbolic logic which organizes demand. The social value of steak or roast, as compared with tripe or tongue, is what underlies the difference in economic value. From the nutritional point of view, such a notion of “better” and “inferior” cuts would be difficult to defend. Moreover, steak remains the most expensive meat even though its absolute supply is much greater than that of tongue; there is much more steak to the cow than there is tongue. But more, the symbolic scheme of edibility joins with that organizing the relations of production to precipitate, through income distribution and demand, an entire totemic order, uniting in a parallel series of differences the status of persons and what they eat.

Of course, there are cultural (and language) differences between nations as to how they name the animals and how they name edible body parts. French is quite different from English in that regard, for instance. In Serbian, the words for muscle-meats from various animals are not cutesy but directly derived from the names of those species: govedo=govedina (cattle=beef), tele=teletina (calf=veal), ovca=ovcetina (sheep=mutton). Where eating animals is both an economic and a cultural necessity, where there is no taboo or even mild unease about eating meat, there is no need to come up with linguistic camouflage.

But what I find most interesting in Marshall Sahlins’ article is this passage:

The exploitation of the American environment, the mode of relation to the landscape, depends on the model of a meal that includes a central meat element with the peripheral support of carbohydrates and vegetables-while the centrality of the meat, which is also a notion of its “strength,” evokes the masculine pole of a sexual code of food which must go back to the Indo-European identification of cattle or increasable wealth with virility. The indispensabilitty of meat as “strength,” and of steak as the epitome of virile meats, remains a basic condition of American diet (note the training table of athletic teams, in football especially). Hence also a corresponding structure of agricultural production of feed grains, and in turn a specific articulation to world markets-all of which would change overnight if we ate dogs. By comparison with this meaningful calculus of food preferences, supply, demand, and price offer the interest of institutional means of a system that does not include production costs in its own principles of hierarchy. The “opportunity costs” of our economic rationality are a secondary formation, an expression of relationships already given. by another kind of thought, figured a posteriori within the constraints of a logic of meaningful order. The tabu on horses and dogs thus renders unthinkable the consumption of a set of animals whose production is practically feasible and which are nutritionally not to be despised.

The American meal – a big juicy beef steak surrounded by a little bit of vegetables mainly as decoration – as a manly man’s meal. The meal of the pioneer, the cowboy, the self-sustained, survivalist, rugged individualist. The beef steak as a descendant of the steak a hunter hunted in the past. Beef steak as a product of the hard work in the harsh environment in the vast expanses of the American West. Only the toughest need apply. The cultural mythology that led to placing beef at the pinnacle, that led to distaste for eating any other species (not for macho men!), that led to taboo against eating horses (companions and co-workers in the difficult production of beef), and that eventually led to hyperproduction of beef for the growing population by consolidating it from small farms into huge feed lots owned by large agribusiness. So, both the illogical, uneconomical, and environmentally damaging food instructure in the States AND the taboo against eating horse may stem from the same cultural source – the early self-sufficient pioneer man.

But that was centuries ago. Surely we have progressed since then. Remember when Michael Pollan made the full circle, from feed lot (symbolic hunt) through a series of organic and local small operations back to the non-symbolic, real hunt, he had difficulty pulling the trigger. We are more civilized now.

In his book A Primate’s Memoir, Robert Sapolsky relates how he adjusts his own diet depending on where he is. Earlier in his career he used to split his year in half. During the half spent teaching neuroscience at Sanford, he was a vegetarian. In America, one has that choice. But in the other half of the year, studying baboons in the field in Africa, he ate what the locals fixed. Yes, a zebra leg. Not just that he would have insulted the hosts by refusing, but if he refused it would incur additional expense and effort of the hosts – they would have to find nutritious plant food every day for him, something that is not as easy to do in that region. There are good reasons why local diet is mainly based on hunted animals.

Thus, the deep roots of the American culture may prevent us from ever eating horse. Although it makes no economical, health, nutritional or environmental sense, that is OK as it makes cultural sense and we can afford this taboo.

But we should re-analyze why outdated machismo is still guiding the way our food instructure works in damaging ways and perhaps do something constructive about it to bring it along into the 21st century, somewhat away from beef and gigantic feed lots and toward a more sustainable, environmentally friendly, public-health reasonable, nutritionally balanced food system.

Good Night, Moon! Now go away so I can sleep.

Mars has two moons - Phobos and Deimos. Here we see Phobos passing in front of the sun, as seen from the surface of Mars. How would having two moons with different phases affect behavior of Martians?

Scientific papers usually don’t faithfully convey exactly how the researchers came up with the idea, or the chronological order in which the investigation proceeded. And there is a good reason for that – papers need to be standardized so other scientists can easily read them, understand them, replicate them and use them to perform further research.

But sometimes, a paper is honest about the process. It is wonderful – and shows that scientists are human, with a great sense of humor – when #OverlyHonestMethods sneak into the text of a scientific paper, surprising and rewarding the careful reader with an ‘easter egg’.

One such paper – on the effects of moon phase of sleep quality – just came out in Current Biology.

The first thing I noticed was that the data were collected in 2000-2003. Why did it take a decade to publish? Was it just sitting on a back burner of a PI for years after the student left the lab? Did it have to go through many rounds of peer review in several journals until it finally managed to get published? None of those reasons, actually! See for yourself:

We just thought of it after a drink in a local bar one evening at full moon, years after the study was completed.

And that is where we encounter yet another effect of the full moon (in synergy with ethanol) on human behavior, at least on WEIRD populations, such as scientists!

But jokes aside, this is also a great example of a paper that usefully re-visits and re-analyzes old data sets. Of course, the authors emphasize the positives of this post hoc approach – nobody at the time of the study could possibly know that the data would be analyzed in this way, so there were no possible subconscious psychological effects – it was a truly triple-blind study:

Thus, the aim of exploring the influence of different lunar phases on sleep regulation was never a priori hypothesized, nor was it mentioned to the participants, technicians, and other people involved in the study.

On the other hand, a study specifically designed to test for moon-phase effects on sleep quality would have been designed differently to ensure it has just the right controls and that maximum information can be derived from the data.

Research in chronobiology is frustratingly slow. In circadian research, each day is just one data point, so each study has to keep subjects in isolation for many days. In the study of lunar rhythms, each month is a data point and the subjects need to be kept in isolation for many months.

To determine if a rhythm is generated by an internal timer (daily or monthly) as opposed to being a direct behavioral response to environmental cycles requires a whole battery of tests, which are hard and time-consuming enough in circadian research, and twenty eight times more so in circalunar rhythm research

Back in the 1960s, it was possible to keep (well compensated) human subjects in isolation rooms for long periods of time (see pioneering research by Wever and Aschoff in the underground bunker in Andechs, Germany). Likewise, animal subjects can be kept and monitored in isolation chambers for long periods of time.

As lunar rhythms are more “messy” than daily rhythms, more data over more time are necessary for the robust statistical analysis. And, due to ethics creep, it is not certain that either animal or human studies of such scope can be approved and performed any more. So, one has to be creative and get quality information out of imperfect experimental protocols (just like we cannot wait to observe multiple cycles of 17-year cicadas, but have to invent creative, short-term approaches instead).

But this time, the researchers were just lucky! Their data-set came from an old experiment which was designed well enough for this new purpose. The key is they had LOTS of data. Their subjects came in to the sleep lab many times and a number of different parameters were measured. Ideally, each subject would stay in the lab for a few months instead of just four days at a time. But having such a huge data set allowed them to weave together a patchwork of fragmented data into a large, trustworthy whole. Each first night of the test was eliminated from the data due to potential influence of the previous day (and the so-called “weekend effect”, as people tend to change sleep times on their days off). Each phase of the moon was covered by multiple subjects multiple times. So they could employ powerful statistics to tease out the effects of the moon phase on various parameters of sleep quality.

And they found some interesting stuff! My colleague Dina Fine Maron has covered the paper in greater detail here. In short, human subjects with no access to information about moon phase, or any ability to perceive the moon itself or its light intensity, nonetheless slept about 20 minutes shorter on the nights of full moon, mostly due to taking roughly 5 minutes longer to fall asleep in the evening than on a night of the new moon. Levels of melatonin, hormone released by the pineal gland during the night, were lower during full moon nights as well. Some of the age and sex differences cannot be explained at this time due to imperfect experimental design – and that is OK. I’d rather see new interesting information coming out of an old data set, than never seeing it at all just because it cannot be “just perfect”.

There are many claims around about lunar periodicities in all sorts of human behavior. For some of those, there is no evidence the claims are true. For others, there is strong evidence the claims are not true. But a few subtle effects have been documented. This paper adds another set with persuasive statistics.

Is this a demonstration that there is a working circalunar clock in humans, operating endogenously, and independently from the actual moon? It’s not possible to tell yet. Those kinds of demonstrations (just like for circadian clocks) require a battery of tests, starting with documenting multiple cycles (I’d say at least three complete monthly cycles) in complete isolation, ability of artificial moonlight to phase-shift the phase of the rhythm in a predictable manner (consistent with a Phase-Response Curve), and hopefully identification of body structures or cellular components which are devoted to generation of the rhythms, with at least some hint of the mechanism how they do it.

We are far from it yet even in animals we can manipulate in lab and field studies. Much work has been done over the decades in the study of lunar and circalunar rhythms in various animals, mostly aquatic and intertidal ones. There are documented lunar cycles (but not necessarily internal lunar clocks) in a variety of organisms, including sponges, cnidaria, polychaetes, aquatic insects, and many different crustaceans including crayfish.

In the terrestrial realm, antlions possess internal lunar clocks, but many other species show modifications of behavior during different phases of the moon, including honeybees, rattlesnakes, ratsnakes, some rodents, some lizards, and lions.

The gravitational force of the moon is so weak that it can affect only very large bodies of water on the Earth’s surface. It cannot even affect smaller lakes and rivers. There is no theoretical mechanism by which any molecule or cellular structure in a human body can be so sensitive as to detect the gravity of the moon. So that hypothesis is out.

In field studies, animals can see and synchronize to the changing night-time intensity as the moon goes through its phases. But in the lab, as in the case of this study, there are no visual clues to the moon phase for the subjects, and, since they had no idea the data would be analyzed for moon phases, they probably did not pay attention to that before they entered the light-isolation lab.

With both gravity and light eliminated as potential clues, the internal clock remains the strongest hypothesis. But it’s still a hypothesis that needs to be tested before one can state with any certainty that it is the case.

As for evolutionary explanations for the existence of a putative lunar rhythm of humans? I would be very careful about this. Demonstrating that any trait is actually an adaptation (and not an exaptation or side-effect of development, or something else) is an incredibly difficult task. Just because something seems “obviously useful” does not make it an adaptation. It is an error of hyperadaptationism to pronounce a trait an adaptation just because it exists, and then to tack on a semi-plausible scenario as to how it may have been selected for. Evolutionary biology is much more rigorous than that kind of lazy armchair speculation.

Sure, if our ancestors actually had lunar clocks as adaptations, it is possible that the mechanism for it may still remain, even if in a weak state, in at least some of today’s humans. But maybe not. And like a rudimentary organ, it does not seem to have any obviously useful function for humans living in the modern society. Twenty minutes of less sleep, that’s all. But it’s good to know. So we can find good use to those extra twenty minutes, perhaps come up with new scientific hypotheses over a pint with colleagues at a local pub.

Bring science and health journalism to #ONA13

The Online News Association Conference is one of the most popular events in the field these days, where prestigious ONA awards are also given to innovators in online journalism. The ONA13 will be held in Atlanta this year, on October 17-19th.

Unfortunately, there is rarely anything on the program that specifically touches on science or health journalism, despite it being a somewhat different – and difficult – area of journalism with some very specific challenges.

Luckily you, the community of science and health readers, can help out. The Program is, at least partially, built through community vote. You can see all the session proposals here. You can ‘vote’ for any of them by clicking on the little heart icon (the “Like” on Tumblr) and/or by reblogging it on your own Tumblr.

If you scroll down again and again and again, you will finally reach the only science-related proposal: Science and Health Go Social: What Journalists Need to Know. You can help this session become a part of the official program by liking and reblogging it, perhaps adding your own commentary.

The session was proposed by Patricia Thomas who runs the excellent Grady Health and Medicine Journalism program at the University of Georgia in Athens.

The proposed panelists are:

Maryn McKenna, blogger at Wired, frequent contributor to Scientific American, and the author of Superbug and Beating Back the Devil.

– Barbara Glickstein, Health journalist, public health nurse and the Co-Director of The Center for Health, Media & Policy at Hunter College City of New York.

– and me.

So, just click here and ‘heart’ the proposal and help us get there and start a discussion on challenges specific to science and health reporting in the rapidly evolving new media ecosystem.

Let’s Not Spring Forward.

Cross-posted from Zocalo Public Square.

Even cows don’t like Daylight Saving Time. Come Sunday morning, when the milking machines get attached to their udders a whole hour too early, the otherwise placid bovines on dairy farms around the United States will snort in surprise and dismay. They may give less milk than usual. They could take days or weeks to get used to the new milking schedules.

We are no different. While most of us won’t be hooking ourselves up to udder pumps, our bodies next week will experience a disturbance very much like the cows’ – one that can affect our mental and physical health. The reason lies in the clash between sensitive, eons-old biology deep within our cells, and human-imposed time-keeping traditions that are barely a century old. Twice every year, when we “spring forward” and “fall back,” our bodies must do battle between “sun time” and “social time.”

Before the mid-19th century, time was more flexible. Each town and village maintained the local church clock more-or-less in sync with the natural light-dark cycles of the sun. The spread of railroads changed all that. The need to keep trains moving in and out of stations at predictable times forced the adoption of a standardized time. That, in turn, led to the formation of time zones.

Daylight Saving Time (DST)—the resetting of all clocks twice a year—was first proposed by New Zealand entomologist George Vernon Hudson in 1895, for quite selfish purposes. He was studying daily cycles in insects and wanted to be able to do more of it during daylight hours. But his idea of maximizing daylight soon spread. The first country to adopt DST was Germany in 1912. Most other countries soon followed, including the United States, which instituted DST in 1918.

The leading argument in favor of DST has always been that it saves energy. Back in the early 20th century, most energy was used for lighting. So, the argument went, placing work and school schedules within daylight hours would save electricity. People wouldn’t need to use light bulbs to navigate around their homes, offices, factories, and fields in the dark, and they would have more time in the evening to indulge in commerce and entertainment.

Today, the situation is very different. The proportion of total energy that is used for lighting is miniscule compared to other, time-independent uses like factories, computers, nuclear plants, airport radars, and other facilities that run 24/7. Energy companies themselves have measured the effect, and have concluded that DST does not save energy.

With this knowledge, some nations have started re-thinking the concept. Russia, for example, abandoned the clock change in 2011, keeping one time all year round. Iceland and Belarus did the same. On the other hand, in 2007, U.S. Congress, clinging to the notion that DST saves energy, moved the onset of DST three weeks earlier than before. That change, I think, makes a difficult transition even more stressful.

Although Congress can impose these changes, it’s a bit unclear who exactly has the right to determine whether DST is implemented. Until very recently, a large number of individual counties in the state of Indiana refused to go through the clock-changing ritual. Arizona doesn’t change its clocks at all—the only state in the union (apart from Hawaii) to defy DST altogether. This lack of clarity about who is in charge may be one of the reasons why a more sustained effort to abolish DST has been unsuccessful nationwide.

Whether or not DST saves energy is the least of the reasons why it’s a bad idea. Much more important are the health effects of sudden, hour-long shifts on our bodies and minds. Chronobiologists who study circadian rhythms know that for several days after the spring-forward clock resetting – and especially that first Monday – traffic accidents increase, workplace injuries go up and, perhaps most telling, incidences of heart attacks rise sharply. Cases of depression also go up. As the faint light of dawn starts preparing our bodies for waking up (mainly through the rise of cortisol secretion), our various organs, including the heart, also start preparing for increased function. If the alarm clock suddenly rings an hour earlier than usual, a weak heart can suffer an infarct.

The reason for negative health effects of DST is that, in essence, the entire world is jet-lagged for a few days. Unlike some animals, like honeybees and reindeer, humans have a very robust circadian clock system that resists abrupt shifts.

Every cell in our bodies contains a biological clock which coordinates the events in those cells—for example, when gene transcription turns on and off, or when specific proteins are made. When we are exposed to a light-dark cycle that is different from what we experienced the previous days, some types of cells synchronize to the new environmental cycle faster than the others. Cells in our eyes, for example, may adjust in about a day, while cells in our brains take a couple of days. Cells in the digestive system and liver may take weeks. So, for weeks after the DST clock change, our bodies are like a clock shop in which each timepiece cuckoos at a different time of day—a cacophony of confusing signals.

Our bodies are constantly being pulled apart by conflicting demands of the natural ‘sun time‘ and culturally imposed ‘social time‘. People living in urban areas may be better shielded from the sun time than their rural counterparts, because of artificial lighting and the skyglow it produces, but nobody is completely isolated from its influence. Twelve noon according to the clock is not twelve noon according to the planet. Citizens of Barcelona and Bucarest are almost two hours apart in their perception of sun time, yet live in the same social time—the same time zone that encompasses most of Europe.

Even those of us who are lucky enough to work from home and can generally set our own work schedules are not completely immune to the effects of DST. I still have to drive my daughter to school at the time prescribed by the local clock, not by local sunlight. My colleagues have expectations about when I will pick up the phone for a teleconference or respond to their emails. I am supposed to show up for my dental appointment at 7am, not “two hours after dawn”.

But if I ever buy a cow—and that is not as crazy as it sounds since I live next door to a dairy farm—I have a plan. Of course I’ll ignore the bi-annual clock changes, which I hear many smart dairy farmers already do. But I’ll go a step further and ignore social time altogether, milking her at the sun time her nervous system can understand, probably the crack of dawn. Whatever I do, I will never make her suffer through the sudden shift of DST. And none of us human animals should suffer it, either.

ScienceOnline – crossing a river with Anton Zuiker

I have been conducting these ScienceOnline interviews for years now, and somehow I never got to interviewing you – one of the founders! It’s high time, don’t you think? So, without further ado, welcome to A Blog Around The Clock. Would you, please, tell my readers a little bit more about yourself? Where are you coming from (both geographically and philosophically)? What is your background? How did you get into medical journalism?

Thank you, Bora. Like you, my last name starts with a Z, so I’m used to waiting for everyone to be called to the front of the classroom to speak. I think that that was one of the early experiences that taught me to pay attention to others. So, it’s been a pleasure to read your interviews through the years and to admire all the unique individuals who have been drawn to ScienceOnline. You’ve done an amazing thing in asking them to share a bit about their lives. The Web — the world — is a better place when we can stop to listen to each person’s story.

I live in Carrboro, North Carolina. I came here 12 years ago, and before that the longest I’d lived in one place was five years as a boy in Idaho. I’ve also lived in Ohio, the South Pacific, Hawaii, Illinois, U.S. Virgin Islands, Arizona, Minnesota and California. I’m the oldest of five sons. My father was a Peace Corps Volunteer (1965-67, Dominican Republic) and coordinator for the VISTA program, then became an attorney. My mother was a parochial-school teacher and principal. In 1981, my parents were watching the nightly news when the television sparked and died. They put it in the closet and never got another, probably the most important parenting decision in my life. I’m a voracious reader because of them. On St. Croix, the house we rented had stacks and stacks of National Geographic, and I set my mind to becoming editor of that journal. Inspired by the photos, I joined the eighth-grade photography club to learn to develop my own pictures.

My high school years were spent in DeKalb, Illinois, my mother’s hometown. I played varsity soccer, was elected student body president, edited an award-winning literary journal, worked summers detasseling hybrid seed corn and walking soybean fields, and with a couple of friends formed a juggling troupe named for the 18th-century Swiss scientist Daniel Bernoulli (our terrific physics teacher suggested that). My dad regularly took me and my brothers into Chicago to visit the Museum of Science and Industry and to see the Blackhawks and White Sox and Cubs (he taught me how to keep the box score, and always have hope), and his stories about being a hard-working vendor — ‘Beer, here!’ — were often more interesting than the games we’d come to see. Dad also taught me to think about the consequences of my actions, and to keep a record of my activities. My mother encouraged me to make new friends and to persevere when my math homework brought me to tears.

When I entered college at John Carroll University in suburban Cleveland, I knew I wanted to be a journalist and to live a life of service, including following in my father’s footsteps and joining the Peace Corps. I also thought long and hard about becoming a Franciscan friar, but decided to become a different kind of father. I fell in love, but moved to Hawaii, where I got to interview astronomer Jerry Nelson in the Keck Observatory. Eventually, I returned to Cleveland, married Erin, and worked as an arts magazine editor. Together we joined the Peace Corps and went to the Republic of Vanuatu, later returning to the U.S. via Australia, Asia and Europe.

So, geographically, I’ve been around. Around the world, quite literally. And philosophically, I’ve learned to be open to that world and its possibilities. My parents taught me to make the best of each and every situation, and how to talk with people to find our similarities and marvel in our differences.

Tell us a little more about your career trajectory so far: interesting projects past and present? And future?

You’re probably still wondering how I got into medical journalism. That came out of my time in Vanuatu. Erin and I both got giardiasis and dengue, and she also got vivax malaria. We saw Hansen’s disease and filariasis and malnutrition and ciguatera poisoning. In the heat of the tropical days, I swayed in the hammock reading the Control of Communicable Diseases manual. When later we moved to North Carolina for Erin to get her masters of public health, I learned about the science and medical journalism program at the UNC j-school, and studied under Tom Linden. I was taking Epidemiology of Infectious Diseases when SARS broke out, and one of the class instructors happened to be Ralph Baric, a coronavirus expert. By now, I knew I was never going to be editor of National Geographic, so instead I was aiming for the New Yorker: my masters thesis project was a 12,000-word narrative feature about acute HIV among college students.

An important thrust to my career trajectory, though, also came from my time in the Peace Corps. That was in the late 90s, and I recognized that when I was done on my island with no running water and no electricity, my childhood dream of being in print would have to change with the World Wide Web. I got a job at an Internet startup company in January 2000, just in time to watch the tech bubble burst from the inside. But I created my first website, became a blogger, and never looked back.

Over the last decade, you and so many other friends and colleagues have helped me combine my passions for journalism, community development and connecting on the Web. We call this the BlogTogether spirit — supporting individuals as they connect through social networks, and then creating ways for them to come together for face-to-face conversations. Those conversations, we’ve seen, promote the golden rule: blog about others as you’d have others blog about you. (I didn’t become a priest, but I’ve found my mission, you could say — or sing, as David Kroll did in Minister of Ether.)

I’m not going to be editor of National Geographic. I may never get into the pages of the New Yorker. But I do hope my career keeps me involved in supporting thoughtful observations about our world.

What is taking up the most of your time and passion these days? What are your goals?

I have a great job, as communications director for the Duke University Department of Medicine. It’s in a vibrant academic medical center, and we use a blog to reflect the activities of our faculty and trainees, such as Nobel laureate Robert Lefkowitz. I was in his office a while back, and loved hearing him talk about how science and humor are alike in helping us see connections.

I recently figured out an important connection in my own life. My paternal grandfather, Louis Sisco, organized the annual Sisco Picnic, and I often helped him set up for that. His devotion to gathering the extended family, and his attention to the details in planning the event, rubbed off on me. I’m pretty sure that’s one of the reasons I’ve spent the last 10 years organizing events and meetups, from the Narratives of HIV series to BlogTogether Backyard Barbecues to our shared ScienceOnline conferences. This year, though, I’m taking a break from organizing events. ScienceOnline has become an official organization, and Karyn Traphagen is charging ahead with great momentum and ideas – hers is a detail-oriented mind that my grandfather would admire. I now serve ScienceOnline, Karyn and the rest of our community as chairman of the board, and I will focus on that role. I’m excited to see where this all goes.

Not having to sweat the details of the conference means I have more time to write, and so I’m more actively writing on my blog. I’ve learned that the more I write on my blog and in my personal journal, the more balanced I am. That’s helping me to spend more time with my daughters, who need me to encourage them through their math homework, and two-year-old Oliver, who needs me to explore in the woods with him just like my dad did when I was young.

I’m in my forties now, and spending this decade learning to be a better storyteller. I love to hear great stories at the Monti, and Jeff Polish inspired me to convene the Talk Story narrative variety show. Karyn showed us postcards she wrote to her mother, and my friend Carter Kersh has gone on to tell two stories at The Monti, for which he’s been nominated for the Hippo Awards. I’ve stumbled through a few of my own stories. I may never be a great storyteller, but I do know that I’m becoming an even better listener. If my gift in life is to facilitate conversations and help other people share their stories, then I’ll continue to do that as humbly as I can.

Through my writing, my listening, my living, I’m trying to be ever more thoughtful, kind, patient and passionate.

You once described your life philosophy as crossing-a-river. What does that mean and how does it work?

I’ve spent a lot of time at the edge of the water – watching contemplatively as mountain rivers cascade, or expectantly as ponds begin to freeze over, or contentedly as the sun sets over oceans and seas in which I’ve just surfed or snorkeled or paddled. As my family moved around, and my parents taught me to find opportunity in each new place, I came to see my life as a journey across a wide river strewn with stepping stones, each stone offering new possibilities for forward or lateral movement toward that other river bank. Some steps are shorter and seemingly less memorable, others further and riskier. I’m certain I’ve fallen in a few times – the story I’ve told my daughters the most is the one about rafting on the New River, tumbling over and losing my favorite Greek fisherman’s cap – but I’m also sure that each moment has strengthened and deepened.

(As I’m writing this, sitting in 3CUPS sipping keemun hao ya, there’s a young guy at the next table over, strumming an ukulele. That makes me remember meeting the gentle giant Israel Kamakawiwoole and Big Island lutier David Gomes. Part of the allure of my crossing-a-river metaphor is the joy in looking back at the steps I’ve taken and the people I’ve met along the way.)

When I graduated from college and decided to move to Hawaii — away from the woman I dearly loved — a mentor told me something simple and profound. “Anton, if it doesn’t work out, you can always come back.” I took it to mean that I need never feel trapped, or choiceless. After two great years in Honolulu, I did return to Cleveland as Erin was finishing college. Ever since, she’s been my companion on that river crossing.

You have been blogging for a very long time, you are one of the pioneers of the form, and you have helped many other people start their own blogs. How do you see the evolution of the blogging form in the near future, both regarding your own blog, science blogs, and blogging in general?

As I used to explain in our Bloggging 101 tutorials, blogging developed in some of the same ways as the early Internet, from What’s New pages to filtering lists to personal-perspective journals. After all these years, blogs can be any or all of these types of online writing.

Social media networks such as Twitter and Facebook and YouTube and Flickr and Instagram have given us tools to share short messages and photos and videos. It feels to me that blogs posts have lengthened (you’re the outlier, of course!), and are more essay like. Last fall, we held the Back to the Blog meeting at Duke University to discuss some of the trends in blogging, including minimal styling, responsive design and using social media to alert your networks to your new posts.

I’m still gung-ho about blogs. I still know more people who don’t have blogs than I know people who do blog. That’s a lot of people to recruit to the blogging life.

That includes scientists, of course. One of the early foundations of the ScienceOnline community was the colorful tapestry of science blog networks, and now in ScienceSeeker we have a fantastic tool for mining the rich daily output from science blogs. But even in my own institution, Duke University, there aren’t that many scientists actively blogging. You remember the keynote speaker at our first ScienceOnline conference back in 2007: Dr. Hunt Willard suggested it would have to be the postdocs and fellows who would need to be trained to use online tools. At Duke, Dr. Zubin Eapen and the cardiology fellows are a shining example of that; Dr. Matt Sparks is another. It’s going to be fun to see others take up online science just as avidly and successfully.

I’ve been thinking a lot about my own blog recently, both in terms of the design and my writing style. I started my blog in 2000 to honor my grandfathers and relatives, and to share my own life and work and travels. I think of my style as storyblogging, in which I start with a current happening, relate it to a story in my or my family’s past, and make an observation. After 13 years of writing, I’d begun to doubt whether I had anything else to record. And, yet, when I search my archives for an anecdote or reference I’m sure I’ve blogged before, I don’t find it. I’m only halfway across my river, so I guess I’ve got a lot more to share. But I also know that Narcissus sat along the water and reflected on himself to unhappy consequence, so I want to challenge myself to add other layers to my blogging, such as deeper exploration of one of my areas of interest. You’ve written much about niche blogging, so maybe I’ll finally develop a niche other than myself.

You have been involved, for a long time, in different nodes of the blogosphere: science blogs, medical blogs, technology blogs, food blogs, local North Carolina blogs — what have you learned from these different communities? What’s on your blogroll of blogs to read daily?

I’ve learned that no matter the subject or node, when interesting people are given the tools — pencil, press, microphone or weblog — to delve deeply into their interests and reflect their areas of specialty, we end up with an awesome deluge of information, insight and inquiry. Niche blogs are great for the ways they focus on a topic or industry, and I understand your argument for writing only about one’s area of expertise. But I’m also convinced that when a writer steps out of his or her niche to provide glimpses of other interests or fragments of experience, we learn more about the person. And knowing more about each other helps us relate to each other better. I believed that at the beginning of the BlogTogether experiment, and over the last seven years, the ScienceOnline community has simply astounded me with its respect and friendship and inclusiveness and camaraderie.

I’ve been reading Dave Winer for a decade, learning from him and using his new World Outline tools, and I cherished the chance to go for a bike ride with him last summer. Michael Ruhlman and Ilina Ewen and Dean McCord are my food and beverage inspirations. 33 Charts, by Dr. Bryan Vartabedian, is quite relevant to my medical communications job. I read design blogs, web technology blogs, blogs by business leaders and venture capitalists, and personal organization blogs. I use Reeder to scan RSS feeds, and I’m rebuilding my river here. On Sunday evenings, I iron my shirts for the week, listening to podcasts by The Monti, Story Collider, StoryCorps and Joel Dueck.

Family looms large in your life and in your writing. Your personal blog is essentially a chronicle of several generations of your family, with you as an acute observer and eloquent archivist. Tell me what family means to you. Are you hoping that your children will continue preserving the family’s stories?

When I was in the fifth grade in Idaho, my mother was my teacher. One day, her assignment to the class was to write a story about the first snowflake to fall in winter. Around that same time, my father would gather me and my brothers in the kitchen, where he used the bare white wall to show his Peace Corps slides. In the mailbox each week, we’d get typewritten letters from my grandfathers: Zuiker Chronicles, from Frank the Beachcomber, were travelogues and camporee reports, while the two-page ‘peek into grandpa’s diary’ detailed the daily routines of Grandpa Sisco. The narrative lives of my ancestors were a daily presence in my youth. I’m a writer because of them.

In middle school, one of my favorite authors was James Michener. I read Caravans and Space, and when I read The Source, I became enamored with archaeology. Years later, on a holiday break during college, I visited my father on the island of St. Thomas. He hooked me up with a friend working on a dig in the hills where construction for a mall had uncovered a pre-Columbian Arawak village. I spent just a day there as a volunteer, carefully brushing dirt and picking out charcoal from a fire pit. Even the tiniest of details of the past, I learned, are important for understanding human history.

The Zuiker Chronicles Online and The Coconut Wireless weblog at mistersugar.com – in many ways, these are my ways of sifting through the little details in the lives of me and my family, and trying to find meaning in the connections.

Erin, my wife, has taught me so much about communication, about being honest and open and always aware of circumstances and contributing factors. While she can gab on the phone for hours, I get twitchy after 60 seconds on the phone, so we make time each week to just sit and talk, and we make sure to listen to the other, looking for the small details about each other that we didn’t know or recall. When we started our family, Erin helped me understand the importance of communicating with our children, reviewing the days activities and reciting bedtime routines. That’s a concept — the small just, just ahead — that I’ve been thinking a lot about lately as I try to incorporate a river of news into my work and blogging.

My children lovingly joke about my blogging, and they know I’m trying to be a better storyteller. But what I hope they take with them into their adulthood is the appreciation that I was present in their lives, much as my father was present in mine, and his father and grandfather before. I hope they feel the connections to those who have come before. I hope they extend those connections into the future.

Even more than medicine and science, your writing revolves around community, storytelling and food. You have been a force in gathering and growing the local online (and offline) community around stories and food. Tell me more about some of the projects and events you organized over time, and what looms in the future?

My mother has no sense of smell or sense of taste. She made a delicious Crock-pot Swiss steak, and tasty chocolate chip cookies, but I didn’t really know what garlic was until I got to college. Our dinners weren’t gourmet, but I do remember them as family meals, all of us sitting down together (no books allowed).

Erin’s mother happens to be an amazing cook, and I quickly figured out that my culinary ignorance offered me a perfect way to hang out in the kitchen, learn how to cook, help out with the dishes, and generally show Erin’s parents that I was going to be a good companion for their daughter. It worked. Now, I love to cook for Erin and our children, and of course I chronicle our meals at home and out on my blog. Most Sundays, I roast a chicken according to the instructions of Michael Ruhlman, whom I’ve hosted three times for food blogging events. I enjoy the process of reading recipes, gathering ingredients and putting them together for something tasty, such as the slivovitz that we enjoyed last week. One lesson I learned: don’t make kimchee, with its fermented shrimp paste, when your wife is six months pregnant.

Good food, good wine, good friends, good conversation — I crave these, and The Long Table has been one way I try bring them all together. Our first dinner was quite fun, with a bunch of people standing up to tell their own food-related stories. With ScienceOnline in good hands, I hope to do more of these dinners in the next few years. I still want to organize a food blogging conference, and maybe someday we can do a conference on food-science blogging.

What aspect of science communication and/or particular use of the Web in science interests you the most? What platforms and what types of online activity have you found most useful, or most gratifying to use? What new platforms or method of online communication, if any, are you excited about?

Well, the intersection of story and science is what got me into medical journalism, and it’s what still drives me today. The ScienceOnline community is filled with great examples of science stories told well. I’m watching #scio13 and ScienceSeeker daily to keep up. And the blitz demonstration sessions at ScienceOnline2013 will surely introduce me to new platforms and approaches.

I mentioned my high school physics teacher above. He assigned our class to work in teams on an experiment. My buddies and I wanted to study the Doppler effect, so I borrowed a tape recorder from my Grandpa Sisco, and met Kevin and Craig on a quiet country road late one night. We drove our cars past each other at different speeds, Craig in his Camaro with horn blaring, me in my Catalina with the tape recorder on. Just now I had to look up Doppler on Wikipedia to refresh my knowledge, but that experience of learning together with friends never dissipated.

Collaboration, clearly, is key these days in science. At Duke, a lot of my communications plan aims to help our investigators connect with their faculty colleagues to explore new multidisciplinary and team-science collaborations. On the Web, I’m interested in exploring how we can build personal network publications, something beyond multi-author blogs and something that can feature contributions from those who aren’t already writing on the Web. Many of my friends and relatives still do not have blogs of their own, and I’m interested creating some sort of online publication with them. Marco Arment’s new app/pub, The Magazine, and the writing platform Medium are helping me think about the possibilities.

You’ve been at every ScienceOnline conference, of course. What’s most memorable of any or all of them? How do you hope ScienceOnline2013 is similar or different?

Actually, ScienceOnline2013 is going to be my first. Learn why in my blog post on The Coconut Wireless.

What I’ve most enjoyed about ScienceOnline is watching the interactions, seeing the passions, witnessing the partnerships. You and I started with a conversation in a cafe, and we’ve gained a friendship and a community. I sincerely hope that all who attend ScienceOnline2013 and the many other events to follow will similarly be better persons because they openly engaged in the conversation.

Please share three descriptive words you hope people would use when talking about you.

Passionate. Pleasant. Present.

No rats in Ryder Alley

Last week, in the wake of superstorm Sandy, I saw a number of people asking questions on social media (and some traditional media picking up on it) about a potential for ratpocalypse, i.e,. the possibility that hordes of rats will come out of the sewers and subway tunnels and flood the streets of New York City in a Pied Piper style. So I wrote a blog post debunking this and explaining why this will not happen, which made me a temporary expert on behavior of rats in storms, so I got interviewed in various places, etc.

As I noted at the very end of the post, my main source of information, at least initially, was a book, Rats: Observations on the History and Habitat of the City’s Most Unwanted Inhabitants by Robert Sullivan. I read it several years ago, when it first came out, and loved it. Reading it provoked me to read more on the topic, so when these questions came up, I already knew most of the answers, and knew where to look for additional information.

The book describes a year in Sullivan’s life, spent observing rats by night, and researching them by day. He went every night downtown to Fullton Street, and just stood there in the middle of two L-shaped alleys: Edens Alley and Ryder Alley. He watched rats come out at night, eat the food discarded by the two restuarants edging the alleys one on each side, fight, hide, and whatever else rats do when they are up on the surface.

The first opportunity I had to go up to New York City after reading the book was in 2007. I just could not resist! The book has no photos of the alleys, so I just HAD to go and see them myself.

My wife and I hailed a cab. Told the driver: Edens Alley. Driver: Hmmm, this is my first day on the job, do you know how to get there?

This was before I had iPhone, GPS, Google Maps…. I pulled out an old-style map, printed on paper, and gave the driver turn-by-turn directions. Once we got there (after making several circles around the area), the driver refused to take any money. I forced him to take double the amount of the fare. He did well for the first day as a NYC taxi driver. This place was hard to find. And off the mid/up-town grid.

Of course, this was in the middle of the day. I did not expect to see any rats there at that time. If I did, that would be an indication that the underground population is astoundingly large, forcing some of the sub-dominant individuals to forage during the day. But I was looking for traces of rats, and for holes and crevices from which they emerge at night, for bags of garbage full of Chinese food, and I took the pictures. I had the pictures stashed away in my Dropbox for more than five years. This is the first time they see the light of day. See for yourselves:

ScienceOnline2012 – interview with Maryn McKenna

Every year I ask some of the attendees of the ScienceOnline conferences to tell me (and my readers) more about themselves, their careers, current projects and their views on the use of the Web in science, science education or science communication. So now we continue with the participants of ScienceOnline2012. See all the interviews in this series here.

Today my guest is Maryn McKenna (blog, Twitter).

Welcome to A Blog Around The Clock. Would you, please, tell my readers a little bit more about yourself? Where are you coming from (both geographically and philosophically)? What is your background? Any scientific education?

I’m a journalist working in several different channels: I blog (for Wired), write medium-length pieces (as a columnist for Scientific American), write long-form pieces (for a variety of magazines) and write books: so far, Superbug, about antibiotic resistance, and Beating Back the Devil, about the CDC’s disease detectives.

Tell us a little more about your career trajectory so far: interesting projects past and present?

I fell into science-writing sideways — in my case, through studying theatre, becoming a dramaturg, realizing I was about to starve, going to journalism school and coming out as a finance reporter. My first newspaper job involved doing analyses of sleazy savings and loan deals. That made me into an investigative reporter, and my next two newspaper jobs involved investigations into public health issues: in Cincinnati, cancer clusters near a closed nuclear-weapons plant, and in Boston, the earliest cases of Gulf War Syndrome. On the basis of those I ended up working in Atlanta as the only reporter assigned to full-time coverage of the CDC, which basically meant wheedling my way into (many) outbreak investigations.

This is a good place to answer the education question. I didn’t study science as an undergraduate; I studied science writing for my masters’. But once it was clear I was going to be a public health reporter, I used journalism fellowships to do post-graduate work, including a year at University of Michigan studying the social history of epidemics and a year with the Kaiser Family Foundation studying emergency rooms.

What is taking up the most of your time and passion these days? What are your goals?

I am in the proposal stage for a book that will look at the intertwined histories of antibiotic development and modern agriculture. My goal is to figure out how to free up enough time from the rest of my life to work on it!

What aspect of science communication and/or particular use of the Web in science interests you the most?

I’m fascinated by how communities self-assemble on Twitter, and I’m increasingly interested in how social media can be used to support public health, for instance through crowd-sourced surveillance.

How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, Google Plus and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?

Blogging (first at Blogger starting in 2007, then Scienceblogs, then Wired) has been essential to my re-invention: from a newspaper reporter to a freelance journalist, and from writing only about public and global health to venturing into food policy as well. Blogging gave me a publication space, gave me an identity, gave me an audience and community. My professional life now could not exist without it. In addition, I’m on Twitter, Tumblr, Facebook, LinkedIn, Flickr, Pinterest and some semi-closed networks such as GoodReads, and I feel as though all of those support and extend what I (try to) do. Twitter in particular is essential to me — not just for community but also for identifying and researching stories.

When and how did you first discover science blogs? What are some of your favourites? Have you discovered any cool science blogs by the participants at the Conference?

I think I “discovered” science blogs around the time I stumbled into blogging myself, and I don’t think I could say at this point who first caught my eye. “Favorites” is a very hard question to answer, both because I read so many — my RSS reader has, literally, hundreds of subscriptions in it — and also because I fear to accidentally leave out people whose work I really do like. But if I only have time to read a few, I will always go first to my Wired colleagues and friends Deborah Blum and David Dobbs; to Ed Yong, of course; to Tara Smith for her insights and Mike the Mad Biologist for his outrage; and to Maggie Koerth-Baker not just for her choices but for her pitch-perfect voice. For deep dives in diseases I love Contagions, Body Horrors and the mysterious Puff the Mutant Dragon. And for knowing what’s up on the food-policy side of my life I rely on Mark Bittman at the New York Times, Tom Philpott at Mother Jones and Helena Bottemiller at Food Safety News.

What was the best aspect of ScienceOnline2012 for you? Any suggestions for next year? Is there anything that happened at this Conference – a session, something someone said or did or wrote – that will change the way you think about science communication, or something that you will take with you to your job, blog-reading and blog-writing?

For me it’s the face-to-face meetings above all. Writing is a lonely business, especially for freelancers, and most especially for people like me who live in parts of the country where there are not dense artistic cultures. (I live mostly in Atlanta: great for public health, not great for random creative interaction.) To have so many people rejoicing in each others’ obsessions is fantastic. Even more, though, I love ScienceOnline because it brings me gently face-to-face with my unknown unknowns; that is, the conference and community introduce me every year to so many people who know more about my subjects than I do. I always come away not only with fresh ideas but also with the knowledge that I have met people whom I can trust to educate me, with enthusiasm and without judgment, when I need them.

Charlotte’s Web: what was she smoking?

“Don’t touch those webs!”

Me and an enormous spider, at the Natural History Museum in Berlin, 2008.

A couple of decades ago, my wife and I worked on a horse farm where everyone was explicitly instructed not to ever clean the cobwebs inside the barn. Sure, the owners themselves would occasionally, very carefully, almost surgically, remove a few targeted old cobwebs here and there, but the majority of the webs remained up at all times. Explanation? Spiders don’t bother anyone, while flies and mosquitoes bother both horses and humans.

On the other hand, for balance, there is an old Serbian proverb that goes like this: “If there were no wind, spiderwebs would cover the sky”

I assume this is said every time someone complains about the strong eastern wind, Koshava, that sweeps through the country in autumn.

And this situation – spiderwebs covering the sky – is something that happens in Mark Twain’s story Some Learned Fables, For Good Old Boys And Girls, featuring Herr Spider as one of its key characters. I read Twain’s short stories over and over again as a kid. Still love them.

Why are we so enchanted by spiders, in real life, in mythology, and in popular culture? I certainly am, always was.

There were Little Miss Moffet, and Itsy Bitsy Spider.

As a little kid, I watched, and was greatly impressed by the old film Tarantula. Later I could not help myself – just had to watch Eight Legged Freaks and Arachnophobia. And yes, Spiderman, despite its scientific…er, bloopers.

Of course I knew about Arachne and the beautiful myth of the origins of the callipygous Shenora Spider (does such a species even exist in reality?).

And then there are spiders in literature. I was scared by the Spider-Man in John Wyndham’s The Chrysalids. I fought the giant spiders of Mirkwood when I played The Hobbit computer game on Sinclair ZX Spectrum back in 1981 or so, after I have already read the book both in Serbian language and the original English. There was Shelob in Lord of the Rings, and Aragog in Harry Potter.

And of course, the best spider in all of history – Charlotte!

Charlotte. She could write.

Today is the 60th anniversary of the first publication of Charlotte’s Web, the beautiful, haunting story of a talking pig and a writing spider.

Interestingly, growing up in Yugoslavia the first 25 years of my life, I have not heard of Charlotte’s Web until I came to the States. But then I had kids. And kids loved to watch the movie over and over again. So I read the book.

And to this day, occasionally, spontaneously, I start singing “Isn’t it great that I articulate!” An important and heart-felt sentiment for a writer for whom words are toys.

Then I received in the mail (but am yet to read it, I promise I will), Michael Sims‘ book The Story of Charlotte’s Web, a biography of E.B.White and the story of the making of the book.

But not everything is fiction and myth. I am a scientist at heart. Each one of those invented characters always made me want to learn more about the real creatures.

A couple of months ago, I went to the American Museum of Natural History in New York City (thanks for the tickets, you know who!) to see their new exhibitSpiders Live. Yes, “Live” is a good description – there are plenty of living specimens in there, many quite fascinating.

As usually happens in museum exhibits, there was plenty to learn about what we know. Anatomy, physiology, ecology, evolution, geography, behavior. Sure, there were a couple of non-spiders there, like scorpions, but it was clearly explained exactly why they are not spiders and how they are related.

One could see a short video showing how Gladiator spider catches its prey by throwing a carefully counstructed web trap on it, like this:

And they mentioned the Bolas spider which catches its prey by lassoing it in with its bolas-like ball of silk:

Interesting – to me at least, as a chronobiologist – is that the Bolas spider uses its circadian clock for an interesting function – it produces different blends of chemicals in its pheromone at different times of night (pdf) to coincide with different times when two different species of moths are flying around, each species attracted to a specific mix of aromatic chemicals.

But beyond learning facts, I was also looking at the ways the exhibit tries to include the scientific process – how we know what we know about spiders? I was looking for, perhaps, descriptions of ingenious experiments on the courtship signaling in wolf spiders, or the research on unique social, colonial spiders. Nope.

There was a part, at the end, which described how scientists collect spiders in the field, how they catch them, preserve them and label them.

And then I saw what I was really looking for. Yes! They did it! The exhibit had a really nice description of my favorite spider research ever! And there it was, The Charlotte’s Web connection, and my own personal connection! I talked about it at the last #TriSciTweetup at the NC Museum of Natural Science in Raleigh NC, for the inaugural Lightning Talks with Brian Malow on Thursdays at the Daily Planet Cafe:

Back in 1948., zoologist H. M. Peters was studying how spiders spin webs. He was getting tired as he had to do all of his research late at night, when spiders spin their webs. So, he asked his friend Peter Witt, a pharmacologist, if there is anything that he could give to spiders that would make them spin during the day. Peter suggested amphetamines. It did not work. Spiders kept weaving at night. But, oh my, their webs looked crazy! They were like impressionist art!

Many spiders embellish their webs with these designs, called stabilimenta, but the reason is unknown.

Peter Witt was an amazing person, a wonderful man. I had the fortune to meet him once, in 1998, just a couple of weeks before he died. He was the Head of the institute for brain and behavior at Dorothea Dix hospital in Raleigh, now unfortunately closed.

Intrigued by the results his friend Peters got when giving spiders amphetamines, he turned his own research into that direction, using spider webs as windows into the way different chemicals affected the nervous system. Some of those were pharmaceuticals of the day. Others were drugs found relatively easily on street corners back in the 1950s and 1960s. Both were of interest to science, of course, for different reasons.

Different drugs had different effects on the shapes of the web. In high doses, almost every drug resulted in highly irregular webs. But at carefully chosen lower doses, there were some interesting differences. For example, under the influence of caffeine, the webs were vertically shorter but horizontally wider, as spiders made larger angles between the radial spokes of the web.

The most striking was the effect of LSD-25. Yes, LSD. This is the only drug which resulted in webs being more carefully weaved and more perfect than the controls.

Charlotte? Is that you?

Many years later, I was teaching a lab at NCSU in animal physiology. Part of the lab was a project, done by students under my supervision. Some students did projects on humans – each other. But the other half used animals. Invertebrates, as there was no time to get an IACUC (institutional animal care and use committee) approval for use of vertebrates (that is a long and difficult process).

One of my students decided to use Peter Witt’s experimental protocol, applying a chemical that he never used way back then – serotonin. Result? Spiders made decent webs, but they took about twice as much time to make them. They went slow about it. They made perhaps half of the twists of the spiral before deciding that was the end, leaving about twice as much space between the loops of the spiral.

Spider brains are large and complicated. They are so large they can’t even fill just the head, a part of them fills the thorax. Of course, spider brains are difficult to study. Not to mention that we do not have a spider genome sequenced yet so we do not have the tools to monitor what is happening in a spider brain. Thus, this line of research has been largely abandoned.

But it was not all in vain. Apart from being able to categorize substances along the lines of their effects on spider webs (often corresponding to their effects on human brains), this method now has a place in agriculture. Placing a few spiders in a field or orchard overnight and taking a look at the webs in the morning can tell the researcher if there are pesticides there, and perhaps which class of pesticide if not the exact kind.

Perhaps there is something in the air that can induce a spider to write “Terrific” and I’d love to know how it does that.

Stumped by bed nets, mosquitoes turn midnight snack into breakfast

Anopheles mosquito (unknown source)

Anopheles mosquito (unknown source)

One of the most effective methods for the control of spread of malaria is the use of bed nets infused with insecticides. Most species of mosquitoes (the Anopheles genus) that carry the malarial parasite (Plasmodium falciparum) are considered to be strictly nocturnal – they are active only during the night.

Thus, sleeping under the net provides protection against getting bitten by the insect vectors of the disease. The net does it in two ways – by providing a mechanical barrier between the mosquito and the human, and by killing mosquitoes that get in contact with the infused insecticide.

As we have learned many times, often the hard way, evolution tends to find a way around such tricks. A number of Anopheles species or local populations have evolved resistance to pyrethroid insecticides usually used in the nets. Yet, the mechanical protection of the net should still be effective, right?

Not so fast! A new study published in September 21 in the Journal of Infectious Diseases documents a behavioral change in a local mosquito population that effectively works around the safety protection of bed nets. What do they do that’s new? They changed the time of day when they bite!

Malaria-carrying mosquitoes are thought to all be strictly nocturnal. Recently, this dogma has started to be questioned, mainly because the rates of malaria did not significantly diminish in areas where bed nets have been implemented. Perhaps they fly and bite during the day, yet nobody bothered to test that hypothesis yet? A previous study noticed a shift in timing of activity and biting from middle of the night into early night. This study was quite systematic – repeating the experiment in two locations in Benin at three time-points: before, during and after the full implementation of bed nets in both locations.

Chronogram of the experiment. Translation for humans: 'chronogram' is an "aren't we sophisticated in our clever use of silly, opaque, uneccessary jargon" version of 'timeline'.

Chronogram of the experiment. Translation for humans: 'chronogram' is an "aren't we sophisticated in our clever use of silly, opaque, uneccessary jargon" version of 'timeline'.

What did they do? They collected mosquitoes in large numbers and recorded the time of day they caught mosquitos. In addition, they used morphology to identify the genus, and PCR to identify the species. Every single mosquito was Anopheles funestus. They tested the caught mosquitoes for pyrethrin resistance and did not detect any – every single mosquito died. Thus all the changes were strictly behavioral.

How did they collect them? They placed humans in strategic places as living targets. It looks pretty much like this video, except they actually captured the insects into vials, then transferred them into small bags:

During the period of just a few years as the bed nets got implemented in the two villages, local mosquitoes dramatically shifted the timing of activity. Instead of 2 or 3am, they now predominantly bit humans around 5am:

Shift in timing in mosquito activity in two locations over three sampling periods.

Shift in timing in mosquito activity in two locations over three sampling periods.

What does that mean?

First, we don’t know yet if this was an evolutionary (i.e., genetic) change or a purely behavioral change. It is possible that there was quite a lot of genetic variation in timing of activity in the population a few years ago and that the bed nets provided a selective regimen that skewed the population to consist mainly of late night and dawn-active individuals. It is also possible that there is sufficient behavioral plasticity in the mosquito allowing it to learn the new best time of day to go out foraging. I’d love to see the mosquitoes placed in isolation chambers to monitor purely genetic patterns of circadian rhythms of activity.

But let’s think more in ecological terms. There are several players here: the Plasmodium parasite, the Anopheles vector, the human host, and predators that eat mosquitoes, notably bats. I have written at length about this a few years ago. Here’s a simple schematic of how the system works when undisturbed:

A crude schematic of possible timing of activity in this ecological system

A crude schematic of possible timing of activity in this ecological system

If the mosquito shifts to almost dawn, what happens?

First, the humans are up and about, outside of nets, readily available to bite. If the humans are healthy but mosquitos are carriers, this is a good way to transmit malaria to them.

But the humans who are sick, the sources of malaria, are still not available. At the times when they undergo “quaternary fevers”, which are the times when malarial parasites are present in their blood (I explained this in great detail before), they are safely hidden by the nets in the middle of the night and they are not bitten by late-biting mosquitos.

Second, a mosquito that bites a human around dawn is much more likely to get detected by that human and be swiftly turned into a small, bloody mush.

Third, while a mosquito that flies around dawn may be able to avoid some of the bats (though not all of them – many bats hunt until the break of dawn), they are now increasingly vulnerable to other predators – frogs, lizards and birds – that tend to hunt at dawn.

As it often happens, there are pros and cons when it comes to evolving new adaptations. The bed nets are now selecting for new adaptations in mosquitoes. It is hard to predict what will be the pros and cons of those adaptations for human health, or the pros and cons of those adaptations for mosquitoes and their survival, or pros and cons of these adaptations to insects’ predators. Future research on this will be both very interesting to watch and very useful for control of malaria.

The Scienceblogging Weekly (August 26th, 2012)

The week was too busy to finish this on Friday. Then on Saturday the news broke that Neil Armstrong died – something I wanted to highlight as a special topic – so I decided to wait another day and give people a chance to wrote posts and articles about Neil. So, with a delay, the weekly linkfest is here!

 

Blog of the Week:

We are all in the gutter is a an astronomy and astrophysics group blog. The title of the blog comes from the quote “We are all in the gutter, but some of us are looking at the stars.” from Lady Windermere’s Fan by Oscar Wilde. Emma, Niall, Rita and Stuart are astronomers, astrophysicists, star-gazers and space geeks at various career stages, having fun with their blog, exploring the universe from every angle they can possibly think of.

 

Top 10:

Unless They’re Zombies, Fossils Don’t Live by Brian Switek:

I hate the phrase “living fossil.” The term should be eradicated from the vocabulary of science writers, and anyone who employs it should be promptly encased in Carbonite. “Missing link” is the only slogan that pisses me off more. My acute allergic reaction to the idiom may be a little overwrought, I admit. But, to me, “living fossil” is nonsense that obscures more than it elucidates. Take the coelacanth, for example….

Hyenas Eschew Lent, Chew Donkeys Instead by Anne-Marie Hodge:

Anyone who has ever attended a holiday parade or gone on a summer vacation knows that cultures tend to create their own seasonal patterns. In much of Western culture, December is a time of much celebrating and feasting, while similarly wintry January is relatively dreary and dull (after New Year’s celebrations subside). This raises a question: how do the behaviors and culture of a society affect the animals that depend upon that society’s garbage for their food? The progressive encroachment of human settlements into the habitats of wild animals has opened opportunities for animals to avail themselves of human refuse. A raccoon in North America is likely to find a juicy watermelon rind in July and leftover turkey remains in November. Perhaps equally enticing for a roving dumpster-diver, but by no means nutritionally equivalent….

Why Is the Night Sky Turning Red? by Amy Shira Teitel:

The idea of a red sky at night used to invoke beautiful images of vibrant sunsets, the product of warm sunlight bathing the sky near the horizon. The adage of “red sky at night, sailor’s delight” refers to a calm night ahead; a red sunset suggests a high-pressure system in the west is bringing calm weather. But red skies at night have taken on a new meaning in recent decades. As outdoor lighting become increasingly prominent, our night skies are gradually turning from black to red….

When will we find life in space? by Phil Plait:

One of the reasons I love astronomy is that it doesn’t flinch from the big questions. And one of the biggest is: are we alone? Another reason I love astronomy: it has a good shot at answering this question…

Paleo-politics: The really long view by Will Femia:

…..The other explanation is that the Cretaceous ended when, 65 million years ago, an asteroid (or asteroids) slammed into the earth, right across the future-Gulf of Mexico at the tip of the Yucatan Peninsula. Not only did the impact and resulting fallout from that asteroid kill the dinosaurs, it also wiped out huge quantities of marine life, including many of the “tiny marine plankton with carbonate skeletons” (I’m guessing some version of Coccolithophore? Anyone?) that would become the rich soil that slaves would farm on land their ancestors would inhabit in voting districts that would favor Democratic candidates around the turn of the second millennium of the Common Era……

What the Dark Knight knows about holding our urban lives together by Scott Huler:

There’s a lot not to love about The Dark Knight Rises, the crazyish new chapter in the latest Batman cycle: a series of actions and explosions so unconnected that they make a Rorschach test look like a syllogism by comparison; Marion Cotillard’s death scene, which lacked only her eyes rolling up and her tongue lolling sideways from her mouth to equal those put on by toddlers on playgrounds; and Christian Bale’s Batman growl — close your eyes and you think Cookie Monster is saving Gotham City….One thing the movie got right, though, is its focus on the infrastructure systems that serve as the beating and vulnerable heart of our urban existence. Every major plot point directly relates to the built environment and the networks that make every element of our lives possible….

Science For Princesses by Janet Stemwedel:

I have always known that I loved science, that delicious alliance of imagination and methodical testing that could help you figure out something about how a piece of the world worked. However, being born at the tail-end of the 1960s, I grew up in a culture that wanted me to know that girls were not supposed to like science. In fact, between toy commercials and TV shows, teachers and peers, I got the message pretty quickly that science is not something for girls. Rather, girls should turn their attention to more important matters . . . like being properly feminine. There was a way that girls were supposed to be—neat and tidy and pretty and pink and quiet and well-behaved. I was not any of those things. I didn’t want to be any of those things. I didn’t know how to be any of those things. And, as far as I could tell, trying to be those things was not going to help me get my hands on the science-y stuff that I wanted. So what was the point?….

How to Annoy E.O. Wilson by Michelle Nijhuis:

…….During a panel at the Aspen Environment Forum in Colorado, as she describes here, Emma piqued Wilson with her talk of making more nature — of expanding our definition of the natural world to include places humans have invaded, altered, and restored. Spending billions trying to return coastal areas like the Everglades to pre-Columbian “purity,” she added, is a lost cause. Better to invest in upslope reserves, and perhaps even learn to admire the tenacity of invasive species…..

Father’s age dictates rate of new mutations by Virginia Hughes:

With every passing year, men are increasingly likely to transmit new mutations to their children, according to the largest study yet of the so-called paternal age effect, published yesterday in Nature. The findings could help explain why older men are more likely to have a child with autism or schizophrenia than are younger men, the researchers say….

I Am Science…and a Nerd by Craig McClain:

I am a nerd. I was a nerd. I will be a nerd. Perhaps in kindergarten I wasn’t, where nerdom had difficulty establishing itself among the simple lessons of the alphabet, counting, and colors. In kindergarten, we are more or less the same in deficiencies and achievements. But after that, I am pretty confident my geek flag flew. I cannot remember ever being a bad student. Repeated straight A’s and the honor role defined me….

August 18th, 2012: Do you believe in dog?

The Scienceblogging Weekly (August 18th, 2012)

Blog of the Week:

Do you believe in dog? is a brand new blog. It is written by two dog researchers, one in New York City, the other in Yarra Valley just outside of Melbourne, Australia. Julie Hecht you may already know from her wonderful blog Dog Spies, her writing in The Bark, or her research which we covered here at SciAm. She studies (and teaches about) dog cognition. Mia Cobb, the Australian, did her research in animal behavior on birds and ants, but now works on issues of dog shelters, welfare and performance science of working dogs. What is the coolest thing about the blog is that the two of them write for each other, addressing each other in each post, thus teaching and learning from each other in a dialogue to which we are all invited to participate in and contribute.

 

Top 10:

Tales from the OR by Summer Ash:

WARNING: This post contains my blood and guts, literally. If you’re squeamish, I recommend skipping this one. What follows is my journey through the operating room at Columbia-Presbyterian on July 18, 2012. Apologies, but I couldn’t help starting off with yet another pop culture reference (this time from Wes Anderson’s Rushmore)….

An example of why it is important to distinguish evolution as fact, theory, and path. by T. Ryan Gregory:

I, and others, have pointed out that there are three aspects of evolution: evolution as fact, evolution as theory, and evolution as path. Evolution as fact refers to the historical reality that species are related through common ancestry. This is supported by a massive amount of evidence from a wide array of independent sources. Evolution as theory refers to the proposed explanations for how “descent with modification” occurs — mutation, natural selection, genetic drift, etc. Evolution as path refers to the actual patterns that have occurred during the history of life, such as when certain events (e.g., branching points, extinctions, etc.) took place, how lineages are related, when and how many times certain traits evolved, and such. The important point is that these three components are largely independent…

The Childhood Aquatic by John Romano:

There is a structurally integral part of my psyche that is the keystone to my existence. I am not sure how it was placed in such a vital position, but it seems this part of me is embedded in my DNA. Something that I can never remember being without. The absolute and total fascination with the natural world….

Abraham Lincoln and The Embalmer by Romeo Vitelli:

The assassination of Abraham Lincoln on April 15, 1865 shocked a nation still recovering from four years of bloody civil war. Along with the hunt for his killers and the uncovering of the assassination plot against the President and several other members of his administration, there was also the logistic nightmare of his funeral and the need to transport the President’s body by train from Washington D.C. to his final resting place in Springfield, Illinois. Since the funeral train would retrace the route that Lincoln had traveled to Washington following his election, the body would be viewed by millions of mourners along the way during the numerous planned stops. All of which raised the question of how to keep the body preserved long enough to reach its destination. Considering the fact that funeral embalming was a relatively new development at that time, some very special arrangements needed to be made…

Inspiration from bassist Victor Wooten shows me a new way to deal with my “child-as-scientist” frustrations by Marie-Claire Shanahan:

I have a confession to make: I cringe a little every time I see a school science or science outreach program justified by saying something like, “Young children are natural scientists, truly curious about the world” (That particular quote is from the Delaware Museum of Natural History). I feel like a curmudgeon about it because it often comes with really good intentions to get students actively involved in doing science (something I definitely support)….

How a Tick Bite Made Me Allergic to Meat by Helen Chappell:

The last time I ate a hamburger, I spent the night in the emergency room. There wasn’t anything wrong with the hamburger itself—aside from being a bit overdone—but it sent me into anaphylactic shock. It wasn’t always this way…

Are wolves really all that? by DeLene Beeland:

Have conservation scientists become carried away, touting the ecological benefits of wolves where there are perhaps — dare I say it? — not as many as we believe there to be? Perhaps some people in the media, and even some in science, have gotten carried away with the ecological changes that wolves are actually capable of mediating, says globally-renowned wolf biologist L. David Mech in his most recent paper “Is science in danger of sanctifying the wolf?” …

Losing One’s Head: A Frustrating Search for the ‘Truth’ about Decapitation by Lindsey Fitzharris:

If you ever find yourself in a pub with me, chances are that at some point, the conversation will turn to death. Not just death, but the terrifying and horrible ways people have succumbed to it in the past. I have often heard a story retold about a man who attended the execution of his friend during the French Revolution. Seconds after the guillotine fell, the man retrieved the severed head and asked it a series of questions in order to determine whether or not it was possible to retain consciousness after decapitation. Through a system of blinking, the victim allegedly communicated his message back to his friend. The ending to this story changes according to the whims of the narrator… or perhaps the number of drinks he or she has consumed by that time. I wondered: was this the 18th-century equivalent to an urban legend? Or could there, in fact, be a degree of truth in this ghastly tale?….

A Dirty, Deadly Bite by Brian Switek:

Dragons aren’t real. At least, the fire-breathing wyverns and coiling wyrms of medieval lore aren’t. Those reptilian menaces were products of superstition and pre-scientific ideas about prehistoric creatures. They were ugly amalgamations inspired by our fears and actual fossil remains of long-extinct mammals and dinosaurs. But in the early 20th century, reporters excitedly relayed the discovery of what quickly became known as the Komodo dragon – ten foot long lizards that had coexisted with humans on South Pacific islands for thousands of years, but had only just been recognized by western science….

The Itsy Bitsy Drummer by Helen Shen:

Rrrr… RRR… Thack! Thack! Thrusting his front legs skyward, the male jumping spider shakes his rear end to send thumps, scrapes, and buzzes through the ground. He’s playing for a female’s attention, dazzling her eight eyes with semaphore while drumming out seductive seismic signals. A few missteps could turn the spider’s performance into a dinner show—with the star as the main dish. The ferocious female demands precise choreography, set to a groovy beat that UC Berkeley behavioral ecologist Damian Elias is working to decipher….

The Scienceblogging Weekly (August 11th, 2012)

Blog of the Week:

Kristina Killgrove (Twitter) is a bioarchaeologist. Her blog Powered By Osteons covers a wide spectrum of topics on archaeology, bioanthropology, and the classical world. But what it has the most, and is most exciting, are bones. Lots of bones. Human bones. Skulls and femurs and pelvises and what we can learn about the past from studying them.

 

Top 10:

Satisfying Curiosity: preparing for the Mars landing by John Rennie:

…All the Mars rovers so far, from the trailblazing Sojourner to the overachieving twins Spirit and Opportunity, have been extraordinary exploratory robots, but Curiosity represents an ambitious new extreme. Most obviously, it’s much bigger: Curiosity weighs almost a ton and is the size of a small car, whereas Spirit and Opportunity were half as long and a fifth as massive and Sojourner was not much bigger than a large cat….

Muscles and the Lactic Acid Myth by Larry Moran:

…It’s all a myth. Lactic acid has nothing to do with acidosis (the buildup of acid in the muscles). In fact, it’s not even clear that acidosis is the problem, but let’s deal with that another time….

Is a PhD required for good science writing? by Emily Willingham:

…..In fact, as someone who has a PhD in science but has been a writer longer than I’ve been a scientist, I’d argue that it might be better not to have specific training in science if you’re reaching for an audience of nonscientists, depending on what your goal as a writer is. If your goal is to tell a great science story that keeps the nonscientist reading and thinking, “wow” or “I get it,” then scientific training might be an anti-requisite. If your target is critique and analysis of science, then scientific training could be quite useful as long as you don’t let your deep background blind you to what your readers might not understand as well as you…..

What Grown-Ups Can Learn From Kids’ Books by Maria Konnikova:

….The little prince isn’t alone in carrying insights that are lost on a child. What of Alice in her wonderland and mirrored adventures? Alice’s story may have been born from a tale told to children one lazy afternoon, but it became much more: a deep philosophical meditation….

Olympic Physics: Air Density and Bob Beamon’s Crazy-Awesome Long Jump by Rhett Allain:

Even now, there are those who claim that the long-jump record of 8.9 meters that Bob Beamon set in 1968 was so crazy awesome because he accomplished it in Mexico City, which is almost 8,000 feet above sea level. The argument is that the air is thinner, and so there is less air resistance, and Mexico City is further from the center of the earth, and so the gravitational forces are smaller. Does any of this have any impact? And if so, does it really matter?…

Is corn the new milk? Evolutionarily speaking, that is. by Jeremy Yoder:

It is a widespread misconception that, as we developed the technology to reshape our environment to our preferences, human beings neutralized the power of natural selection. Quite the opposite is true: some of the best-known examples of recent evolutionary change in humans are attributable to technology. People who colonized high-altitude environments were selected for tolerance of low-oxygen conditions in the high Himalayas and Andes; populations that have historically raised cattle for milk evolved the ability to digest milk sugars as adults….

In the Bronx, Rights Get Fuzzy by Cassie Rodenberg:

I’ve been working with photographer Chris Arnade to document stories in Hunts Point, Bronx and often-ignored areas of New York City. Over the course of the last year, we have noticed the impact the city’s Stop and Frisk policy has on the neighborhood. Recently, we made the decision to start documenting that in action should we see it. This Sunday, we did:…

What do Christian fundamentalists have against set theory? by Maggie Koerth-Baker:

I’ve mentioned here before that I went to fundamentalist Christian schools from grade 8 through grade 11. I learned high school biology from a Bob Jones University textbook, watched videos of Ken Ham talking about cryptozoology as extra credit assignments, and my mental database of American history probably includes way more information about great revival movements than yours does. In my experience, when the schools I went to followed actual facts, they did a good job in education. Small class sizes, lots of hands-on, lots of writing, and lots of time spent teaching to learn rather than teaching to a standardized test. But when they decided that the facts were ungodly, things went to crazytown pretty damn quick….

Stop Calling Sherlock a Sociopath! Thanks, a Psychologist. by Maria Konnikova:

I’d like to get something off my chest. It’s been bugging me for a very, very long time. Sherlock Holmes is not a sociopath. He is not even a “high-functioning sociopath,” as the otherwise truly excellent BBC Sherlock has styled him (I take the words straight from Benedict Cumberbatch’s mouth). There. I’ve said it…

What’s the difference between “transparency” and “invisibility”? by Greg Gbur:

In writing my previous post on The Murderer Invisible, I started thinking again about the relationship between something being “transparent” and something being truly “invisible”. Most of us can appreciate that, under the right circumstances, a transparent object like a glass window can be very hard to see, but most of us also appreciate that glass is not even close to fitting the popular perception of invisibility. In fact, though we encounter plenty of transparent things in nature, we don’t encounter invisible things….

Top 10:

Gavin’s Story: Whole Exome Sequencing Finds Mystery Mutation by Ricki Lewis:

In a hotel ballroom on the campus of the University of Pennsylvania on a midsummer Saturday in 2010, an unusual roll call was under way at the Family Conference for the Foundation for Retinal Research. Betsy Brint, co-head of organization, was calling out what sounded like code words – CEP290, GUCY20, LRAT – and for each one, a few people would stand up, excited, then form little groups. After all 18 abbreviations had been called, representing the genes known to cause Leber congenital amaurosis (LCA), a few sets of parents were left standing. Troy and Jennifer Stevens, of Chino, California, were among those whose childrens’ genes and mutations were still a mystery….

Alain de Botton Tries Hand at Sex, Fails by AV Flox:

…..The next sections jump into “evolutionary-biological interpretation,” which we took to mean science, and which gave us the distinct impression that the author’s research of sex stopped at the work of William H. Masters and Virginia E. Johnson instead of starting there. That’s not surprising, though. ….

Even Deadly Snakes and Monkey Shit Couldn’t Stop Me From Excavating Maya Ruins in the Jungle by Charles Choi:

Snakes. In the ancient Maya ruins where I’m working at with archaeologists, the creatures we fear most are probably the snakes. That fact might sound like the punchline to an Indiana Jones joke, until you hear about the most dreaded serpent here in the jungles of Belize. The fer-de-lance is likely the deadliest snake in Latin America, packing an amputate-if-you’re-lucky bite if it goes untreated. Its long fangs can go right through a boot, and it’s aggressive – unlike many snakes that seem more afraid of us than we are of them, the fer-de-lance won’t hesitate to strike. ….

The importance of being Aquaman, or how to save the Atlantean from his briny fate by Andrew Thaler:

….There’s no way around it. Even with the huge amounts of heat Aquaman would produce as he burned through his daily 48,000 Calories, he is going to get cold. With little body fat and no fur to speak of, his heat retention potential is pitiful. Fortunately, there are plenty of simple solutions to the thermal problem. Unfortunately, almost all of them involve visible changes to his physique….

Moths, Memory, and Motivation by James Hathaway:

….We quickly found out that something that seemed simple – catching a bunch of pretty colored insects and putting them in boxes – was actually demanding and nearly endlessly complex and mysterious. A lot of the butterflies that were the coolest, the rarest, the most beautiful, lived in strange places – treetops, the edges of swamps and streams, sunlit clearings in deep woods – and only flew in certain seasons and specific times of the day – early spring, late afternoon. We learned why – mating rituals, foodplant availability, lifecycle requirements. We didn’t just read, we observed. We learned that the books were not always right – insects are really variable and behave differently in different locales. We developed hypotheses, collected information that supported or contradicted them. We learned, at least concerning a couple dozen species of butterflies in the part of upstate New York where we lived, how nature worked. Nature taught us the science we needed to use, and science taught us what there was to know. (Not that we knew enough to call it “science, “ of course.) It was like the world had opened up. ….

Pain Control by Shara Yurkiewicz:

She had only been in the hospital twice in her life: once when she was nine and now, 60 years later. She had gotten tonsils out then. She was getting tumors out now. Her abdomen hurt when she was awake. Her abdomen would also hurt during exploratory surgery, although she wouldn’t be able to feel it under general anesthesia. Her body would feel it, though, and could respond by dangerously spiking or plunging her vitals. She needed an epidural before surgery to keep the pain under control…..

Bad Chemistry by Deborah Blum:

The start of the story is this: In December 2008, a 23-year-old research assistant named Sheri Sangji accidentally set herself on fire while working in a chemistry laboratory at the University of California, Los Angeles. She died 18 days later in a hospital burn unit….

Is Childhood Pertussis Vaccine Less Effective Than We Thought? by Maryn McKenna:

Delicately and cautiously, health authorities in the United States and other countries are beginning to open up a difficult topic: Whether the extraordinary ongoing epidemic of whooping cough, the worst in more than 50 years, may be due in part to unexpected poor performance by the vaccine meant to prevent the disease….

Meet the people who keep your lights on and Blackout: What’s wrong with the American grid by Maggie Koerth-Baker:

Power was restored today in India, where more than 600 million people had been living without electricity for two days. That’s good news, but it’s left many Americans wondering whether our own electric grid is vulnerable. Here’s the good news: The North American electric grid is not likely to crash in the kind of catastrophic way we’ve just seen in India. I’m currently interviewing scientists about the weaknesses in our system and what’s being done to fix them and will have more on that for you tomorrow or Friday….

New OCD Symptom: Tail Chasing by Elizabeth Preston:

…Dogs with compulsion may pace, chase imaginary flies, or lick their flanks until they get sores, despite their owners’ best efforts to make them stop. Certain breeds are especially vulnerable. A staple of canine compulsion is tail chasing, which frequently strikes bull terriers and German shepherds. On one forum, user MatrixsDad complains that his German shepherd “is constantly chasing and barking at her tail…She comes up and puts her backside against anyone who’s standing around so she can get a better view of her tail before she starts chasing it.”…

Top 10:

A Killer Without Regret by Deborah Blum:

In the summer of 1920, a 29-year-old son of Minnesota farmers docked his boat (acquired with stolen money) at a small island in New York City’s East River. One by one he hired out-of-work sailors to crew for him. And one by one, he shot them in the head with a Colt .45 and dumped their bodies in the water. Before he was executed in 1930, Carl Panzram put the sailor body tally at 10 although he estimated that was only about half his total murder count. “For all these things, I am not in the least sorry,” he wrote in a jail house confessional. “I was so full of hate that there was no room in me for such feelings as love, pity, kindness or honor or decency.”…

The marathon & Olympic movement on Huffington Post by Greg Downey:

Many people think they know the story of the very first ‘marathon.’ Pheidippides, reputedly the fastest man in the Greek army, allegedly ran from the battlefield at Marathon twenty-five miles to Athens in 490 BCE to announce a Greek victory over the invading Persians. Bolting into the Athenian assembly, he shouted, νικωμεν (nikomen), ‘We have won!’ and promptly keeled over dead….

Galápagos Monday: The People Problem by Virginia Hughes:

…Two-thirds of the jobs on the islands are in the service sector. The tourists come, of course, because of the amazing plants and animals. They contribute money directly to conservation efforts, and their patronage boots the economy and allows the government to set up its own conservation management systems. That’s all great, except — more people also means more: ships, construction, roads, vehicles, hotels, restaurants, water and energy use, garbage, and sewage. All of that threatens the habitats and health of the plants and animals. In other words, the whole thing is unsustainable. The growing economy in the Galápagos is simultaneously supporting more science and conservation efforts and destroying the things that need to be studied and conserved. The economy is eating itself….

Geometry Proves Sheep Are Selfish Jerks by Elizabeth Preston:

Sometimes what looks like friendly behavior is really an attempt to get one’s neighbor eaten by a wolf before oneself. Sheep, for instance, seem cozy enough in their flocks. What’s a better way to travel than surrounded by 100 percent merino? But the real reason they stick close to their neighbors is to save their own woolly rear ends…

Noisy sex means death for flies if bats are listening by Ed Yong:

Some folks just can’t help being loud in bed, but noisy liaisons can lead to a swift death… at least for a housefly. In a German cowshed, Natterer’s bats eavesdrop on mating flies, homing in on their distinctive sexual buzzes….

Wisconsin frac sand sites double by Kate Prengaman:

Tucked behind a hill in rural Trempealeau County, farmland undergoes an industrial transformation. Outside this city of 1,300, Preferred Sands turns Wisconsin’s sandy soil into a hot commodity. A wall of green trees opens to a vast expanse of sand buzzing with activity. Excavators mine and conveyors carry the sand from towering stockpiles up into the processing plant. Every week, this facility ships 7,500 tons of sand by rail to oil and gas fields in Texas, North Dakota and Pennsylvania. …

Language Serves the Group by Edmund Blair Bolles:

Steven Pinker has posted an important essay on group selection. You can gather its thesis from the title, “The False Allure of Group Selection.” Since I am on record saying that group selection (really, multilevel selection) was critical to the evolution of language, I read the essay with strong interest. Let me say right off that I was astonished to find that the essay makes no remarks about the evolution of language. Pinker is a famous proponent of language’s evolutionary origins and biological basis, but he says nothing of group selection and language. Instead he criticizes ideas that group selection explains religion, culture, and nations. I am skeptical of those claims too. Pinker is a fine writer and I got several chuckles out of his examination of various shallow appeals to group selection. Was I laughing at my own doom?…

Ending the AIDS epidemic by John Rennie:

Thirty-one years into the HIV epidemic, health authorities are finally starting to sound hopeful about the prospects for curbing it. If that sentence sounds bitter or sarcastic, it isn’t meant to be. Rather, it’s an honest assessment of how long and frequently depressing the era of HIV and AIDS has been, and of how much misery it has spawned. But it also acknowledges reasons to think that maybe, just maybe that’s beginning to change….

Ending U.S. chimpanzee laboratories will save chimpanzee research by Brian Hare:

…The non-lab research model has now become the dominant research model. In my area of research a collection of just five zoos and African sanctuaries recently published more scientific papers in higher impact journals than all five active U.S. chimpanzee laboratories. These non-lab researchers contributed data relevant to fighting HIV, Malaria, Parkinson’s, Autism, Alzheimer’s, and a myriad of other human ailments. They did this while studying chimpanzees that live life freely in extremely enriched environments. …

One way to successfully invade a habitat: eat the competition by Jeremy Yoder:

The Asian Harlequin ladybug, Harmonia axyridis, eats aphids like they’re Popplers, and it’s been repeatedly introduced into the U.S. and Europe to do exactly that. But since it was first introduced, H. axyridis has spread of its own accord, and displaced native ladybugs. This isn’t just because the Harlequin ladybug eats more aphids, or breeds faster, than the locals; it looks like part of the Harlequin’s success is due to the fact that it eats its native competition….

The Scienceblogging Weekly (July 21th, 2012)

Blog of the Week:

Life is short, but snakes are long is written by Andrew Durso who is a PhD student at Utah State University, where he studies the behavior, physiology, and ecology of toad-eating snakes. So, everything on his blog is about snakes. And every post on his blog has something about snakes that you have not known before.

 

Top 10:

Global Warming’s Terrifying New Math by Bill McKibben:

If the pictures of those towering wildfires in Colorado haven’t convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States. That followed the warmest May on record for the Northern Hemisphere – the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe…

The Mystery of the Missing Chromosome (With A Special Guest Appearance from Facebook Creationists) by Carl Zimmer:

There’s something fascinating about our chromosomes. We have 23 pairs. Chimpanzees and gorillas, our closest living relatives, have 24. If you come to these facts cold, you might think this represented an existential crisis for evolutionary biologists. If we do indeed descend from a common ancestor with great apes, then our ancestors must have lost a pair after our lineage branched off, some six million years ago. How on Earth could we just give up an entire chromosome….

Are Warnings About the Side Effects of Drugs Making Us Sick? by Steve Silberman

Your doctor doesn’t like what’s going on with your blood pressure. You’ve been taking medication for it, but he wants to put you on a new drug, and you’re fine with that. Then he leans in close and says in his most reassuring, man-to-man voice, “I should tell you that a small number of my patients have experienced some minor sexual dysfunction on this drug. It’s nothing to be ashamed of, and the good news is that this side effect is totally reversible. If you have any ‘issues’ in the bedroom, don’t hesitate to call, and we’ll switch you to another type of drug called an ACE inhibitor.” OK, you say, you’ll keep that in mind…..

Battling antivaccinationists at FreedomFest by Orac:

Like so many other skeptics, I just returned from TAM, which, despite all the conflict and drama surrounding it this year, actually turned out to be a highly enjoyable experience for myself and most people I talked to. As I’ve been doing the last few years, I joined up with Steve Novella and other proponents of science-based medicine to do a workshop about how difficult it is to find decent health information on the Internet, and how the “University of Google” all too frequently puts quackery on the same level as reliable sources of medical information because all that matters for most search engines when it comes to ranking search results is the number and kinds of sites that link to a given site…..

Epic fraud: How to succeed in science (without doing any) by John Timmer:

Running scientific experiments is, frankly, a pain in the ass. Sure, it’s incredibly satisfying when days or weeks of hard work produce a clean-looking result that’s easy to interpret. But often as not, experiments simply fail for no obvious reason. Even when they work, the results often leave you scratching your head, wondering “what in the world is that supposed to tell me?” The simplest solution to these problems is obvious: don’t do experiments….

One Molecule for Love, Morality, and Prosperity? by Ed Yong:

Imagine a molecule that underlies the virtues that glue societies together. Imagine that it brought out the better angels of our nature with just a sniff and could “rebond our troubled world.” Imagine that it was the “source of love and prosperity” and explained “what makes us good and evil.” Well, carry on imagining. This is a story about oxytocin, and oxytocin is not that molecule….

How We Changed Penguins Just by Watching by Elizabeth Preston:

If a penguin falls in the forest and no one is there to hear it, I don’t know what kind of forest that is—but everyone who’s interested in penguins is probably hanging out a lot closer to the South Pole. The charismatic birds let scientists and tourists alike get a close look without too much trouble. And all that familiarity has the potential to change penguins, and other closely watched animals, for good….

What Would Happen If a Lion Fought a Tiger? by Natalie Wolchover:

This ultimate cat fight has happened more times than you might expect. The Romans pitted African lions against Asian tigers in the Coliseum, to the rip-roaring pleasure of the Plebeians. A few fights were also staged in the early decades of the 20th century, and on several modern occasions, accidental cross-species encounters at zoos have quickly developed into gruesome scenes guaranteed to scar any nearby schoolchildren for life. But how do these lion versus tiger showdowns go down?…

In Search of Grote Reber by Matthew Francis:

Unlike most sites where the business of cosmology is done, Fermi National Accelerator Laboratory—known colloquially as Fermilab—isn’t in a remote spot. The facility is in Batavia, Illinois, part of the sprawling metroplex of Chicago, and it’s just a short drive from two major tollways. The Standard Model describes a plethora of particles, but it has nothing on the number of fast-food joints and auto shops within ten minutes’ drive of the Fermilab gates. My friend hosting me during my stay in Illinois wasn’t even aware of the lab’s location, despite having friends living close by—the area around it is that dense…

Dancing in digital immortality: The evolution of Merce Cunningham’s “Loops” by Ashley Taylor:

The modern dancer and choreographer Merce Cunningham died in 2009, and his company gave its final performance at the end of last year. Many of his dances will live on in the memories of former company members who go on to restage them. But there’s one solo, “Loops,” that Cunningham never taught to another dancer. This piece lives on through a different medium: digital motion capture…

The Scienceblogging Weekly (July 13th, 2012)

Blog of the Week:

Contagions is a blog written by Michelle Ziegler (Twitter, Facebook, the other two blogs by Michelle – Heavenfield and Selah – are focused entirely on history and not on medicine or science). In Contagions, Michelle explores infectious disease – there is a lot about the Plague – from history to epidemiology to most recent scientific papers. Sometimes gruesome, always fascinating.

 

Top 10:

Is Autism an “Epidemic” or Are We Just Noticing More People Who Have It? by Emily Willingham:

In March the US Centers for Disease Control and Prevention (CDC) the newly measured autism prevalences for 8-year-olds in the United States, and headlines roared about a “1 in 88 autism epidemic.” The fear-mongering has led some enterprising folk to latch onto our nation’s growing chemophobia and link the rise in autism to “toxins” or other alleged insults, and some to sell their research, books, and “cures.” On the other hand, some researchers say that what we’re really seeing is likely the upshot of more awareness about autism and ever-shifting diagnostic categories and criteria….

New technique identifies magnetic cells in animals by watching them spin by Ed Yong:

A migrating robin can keep a straight course even when it flies through a cloudy night sky, devoid of obvious landmarks. That’s because it can sense the Earth’s magnetic field. Something in its body acts as a living compass, giving it a sense of direction and position. This ability – known as magnetoreception – isn’t unique to robins. It’s been found in many other birds, sharks and rays, salmon and trout, turtles, bats, ants and bees, and possibly cows, deer and foxes. But despite more than 50 years of research, the details of the magnetic sense are still elusive….

The Sex Scholar by Kara Platoni:

Decades before Kinsey, Stanford professor Clelia Mosher polled Victorian-era women on their bedroom behavior—then kept the startling results under wraps….

Bloggers and Bowerbirds by Erin Kissane:

There are still a lot of elbows being thrown in the squabble about “creation” versus “curation,” and it seems to be getting worse. As humans tend to do, we’re talking past each other and pretending to simplicity in the face of the complex and the weird. Here’s what I think is going on. I think we’re getting tripped up by two things: clumsy language and a misapprehension about competition for limited resources….

Citations, Social Media & Science by Morgan D. Jackson:

This morning I was reading a newly published paper that I found intriguing, not only for its content1 but also for who it cited — sort of. Among the regular cadre of peer-reviewed journal articles supporting the author’s findings were two blog posts by University of Glasgow professor Roderic Page. Rod is a major proponent for digitizing and linking biodiversity literature with all aspects of a species’ pixel-trail across the internet, so I was excited to see his blog being “formally” recognized. As I finished reading the paper and reached the References section, I skimmed through to see how a blog citation might be formatted. Much to my dismay, after breezing through the L’s, M’s, and N’s I found myself within the R’s, with nary a Page in sight…

Investigation: Drug Resistance, Chicken And 8 Million UTIs by Maryn McKenna:

…I’ve been working with a great new group, the Food and Environment Reporting Network — one of the grant-funded journalism organizations that have arisen in the wake of the collapse of mainstream journalism — on an important, under-reported topic. Which is: Over the past decade, a group of researchers in several countries have been uncovering links between the use of antibiotics in chicken production and the rising occurrence of resistance in one of the most common bacterial infections in the world. The infection in question is UTI, which just about every woman I know will recognize: It stands for urinary tract infection, and on average one out of every 9 women in the United States suffers one at least once per year. There are 6 million to 8 million UTIs in the US each year, costing at least $1 billion in healthcare spending….

The hows and whys of human attraction by Barbara J. King:

Robin Dunbar may not be a household name, but some of his thinking has reached the status of household ideas. You’ve heard that 150 is an approximate upper limit on the number of our family-and-friend relationships because that’s how many connections we can track? That’s Dunbar. You’ve read the theory that language evolved as a sort of replacement for hands-on grooming among our primate relatives when group size got big? That’s Dunbar too. Now, in The Science of Love and Betrayal, Dunbar, who is Professor of Evolutionary Anthropology at Oxford, asks seductive questions about love and friendship. Why do men and women pair-bond when so many other animals don’t? How do biology and sociality intersect in explaining human attraction to others? …

Crimes and Misdemeanors: Reforming Social Psychology by Dave Nussbaum:

The recent news of Dirk Smeesters’ resignation is certainly not good news for social psychology, particularly so soon after the Diedrik Stapel case, but I believe it can serve as an opportunity for the field to take important steps towards reform. The reforms that are needed the most, however, are not restricted to preventing or detecting the few instances of fraud by unscrupulous researchers who are intentionally falsifying data. What we should be more concerned about are the far less egregious, but much more common offenses that many of us commit, often unknowingly or unintentionally, and almost never with fraudulent intent….

The Vampire of Venice Returns, or What Is that Brick Doing in that Skull’s Mouth? by Kristina Killgrove:

It seems like every spring there is renewed coverage of a partial skeleton that was found on the island of Lazaretto Nuovo (one of two 15th-16th century leper colonies near Venice) in 2009. I’ve never covered it here, but since I was alerted to an airing of a documentary about the skeleton on Italian TV this week, I thought it may be time to track the progress of the so-called Vampire of Venice (“il vampiro di Venezia” in Italian, and not to be confused with a similarly named Dr. Who episode)….

How the Deaf Brain Rewires Itself to ‘Hear’ Touch and Sight by Nadja Popovich:

Our experiences help shape our brains. So it might make sense that for a person born without hearing, the part of the brain that’s meant to process audio would be underdeveloped. But according to a new study, those who have been deaf since birth actually use the sound-related part of the brain — known as the primary auditory cortex — to do even more heavy lifting than their hearing counterparts. …

The significance of plot without conflict by Still Eating Oranges

The Scienceblogging Weekly (July 6th, 2012)

Blog of the Week:

Musings of a Dinosaur is a blog written by a physician, family practitioner, Lucy E. Hornstein, author of the book Declarations of a Dinosaur: 10 Laws I’ve Learned as a Family Doctor. Having a small general family practice is different from beeing a specialist in a large hospital. Approach to patients is different. The way one runs the business is different. The thoughts about electronic medical records (a frequent topic of the blog) are different. A valuable perspective, wry and funny and insightful.

 

Top 10:

Maxwell’s demon goes quantum, can do work, write and erase data by Matthew Francis:

At any temperature above absolute zero, particles in a system move randomly, an effect known as thermal fluctuation. The random character of the fluctuations means they cannot be put to work in a mechanical sense (the measure of the energy unavailable for work is called entropy). 19th century physicist James Clerk Maxwell proposed a tiny intelligent “demon” that could harvest the thermal fluctuations to restore their usefulness; later work in the 20th century showed that the demon itself would have entropy, which would keep the thermodynamic books balanced.

Interesting by Shara Yurkiewicz:

I pull up a test result for my patient, and the senior resident standing behind me lets out an excited squeal. “I’ve never seen the imaging come back positive for this,” she says. Our two-week-old infant, who already has a rare infection, also has a rare associated structural abnormality. It’s not benign, but it is fixable. The fix usually requires surgery. As we walk over to the patient’s room to update her mother, my senior gushes about the zebra that was uncovered on the ultrasound. She asks me if I’m excited. “I dunno,” I mutter, which is somewhat more diplomatic than my disgust that she is. ”Her kid has to get surgery now.”

The world’s smallest fly probably decapitates really tiny ants by Ed Yong:

…Even though flies as a group aren’t exactly giants, the new species was around half the size of the previous smallest species. Brown named it Euryplatea nanaknihali after Nanak Nihal Weiss, a young boy from Brown’s home town in Los Angeles. Weiss is an entomology fanatic and Brown hopes that the name will help to keep his interest for years to come….

Creationists and Climate “Skeptics” – Separate Species or Just Different Breeds? by Faye Flam:

Several of the regular readers of this column have told me that since I’ve been brave enough to tell the truth about evolution, I should do the same for climate change and expose it as a hoax. In one case I replied that in my stories I always strive to reflect the truth to the best of my abilities. He wrote that he was “disappointed.” These evolution-accepting climate change “skeptics” are an interesting breed, revealing some key differences in the ways they and creationists approach science. Self-described climate skeptics are much more scattered in their views than are creationists, but they are better organized and together speak with a louder, and angrier voice….

Printing dinosaurs: the mad science of new paleontology by Laura June:

In April of this year, I headed out to a marl pit in Clayton, New Jersey to watch a team of Drexel University students and their teacher, Professor Kenneth Lacovara, dig for fossils. Marl, a lime-rich mud, had been mined and used as the 19th century’s leading fertilizer, but since around World War II (with the development of more advanced, synthetic fertilizers), demand for it has steeply lessened, and there aren’t many marl mining businesses left in the US. The marl pits of Southern New Jersey are famous for something else, though: they have been incredibly rich in fossil finds. In February, Dr. Lacovara had announced that the Paleontology department at Drexel would team up with the Engineering department for what would largely be a novel new project: scanning all of the fossils in the University’s collection (including some previously unidentified dinosaurs of Lacovara’s own finds in other parts of the world) using a 3D scanner. The Engineering department would then take those scans and use a 3D printer to create 1/10 scale models of the most important bones. But, he reported, that wouldn’t be the end of it: they intended, he said, to use those scale polymer “printouts” to model and then engineer fully working limbs, complete with musculature — to create, in effect, a fully accurate robotic dinosaur leg or arm, and eventually, a complete dinosaur….

Childbirth and C-sections in pre-modern times by Kristina Killgrove:

Basically since we started walking upright, childbirth has been difficult for women. Evolution selected for larger and larger brains in our hominin ancestors such that today our newborns have heads roughly 102% the size of the mother’s pelvic inlet width (Rosenberg 1992). Yes, you read that right. Our babies’ heads are actually two percent larger than our skeletal anatomy…

Self help: forget positive thinking, try positive action by Richard Wiseman:

For years self-help gurus have preached the same simple mantra: if you want to improve your life then you need to change how you think. Force yourself to have positive thoughts and you will become happier. Visualise your dream self and you will enjoy increased success. Think like a millionaire and you will magically grow rich. In principle, this idea sounds perfectly reasonable. However, in practice it often proves ineffective….

The Uncertainty Principle for climate (and chemical) models by Ashutosh Jogalekar:

A recent issue of Nature had an interesting article on what seems to be a wholly paradoxical feature of models used in climate science; as the models are becoming increasingly realistic, they are also becoming less accurate and predictive because of growing uncertainties. I can only imagine this to be an excruciatingly painful fact for climate modelers who seem to be facing the equivalent of the Heisenberg uncertainty principle for their field. It’s an especially worrisome time to deal with such issues since the modelers need to include their predictions in the next IPCC report on climate change which is due to be published next year….

The living rainbow: A fatal flaw in a classic study of sexual selection by Jeremy Yoder:

A key component of classical sexual selection theory is the idea that males maximize their evolutionary fitness—the number of children they ultimately have—by mating with lots of females, while females maximize their fitness by selecting only one or a few high-quality partners. It’s pretty clear that this model works well for some species (like ducks), but also that there are many it doesn’t fit so well. Now it looks like one of the “classic” experimental examples of sexual selection may actually fall into the latter category….

Dr. Google and Mr. Hyde by David Gorski:

….Like all major new technologies, the Internet has a good side and a bad side. In many cases, the same property is both good and bad, and one place that this is particularly true is in medical information. The Internet has an abundance of medical information, all there for the reading and learning, and various discussion forums that began with online BBS services and the now mostly obsolete global discussion community of Usenet allow people from all over the world who would never have communicated directly with each other before to share information and experiences. Unfortunately, there is a dark side to this. Regular readers of this blog know what that dark side is, too. The same technology that allows reputable scientists and doctors to publish reliable medical information to the world at very low cost also allows quacks and cranks to spew their misinformation, nonsense, pseudoscience, and quackery to the whole world at very little cost. And, boy, do they ever! In many ways, the quacks are a far more effective online presence than skeptics and supporters of science-based medicine. I mean, look at SBM itself. We’re still using a generic WordPress template. Now look at an antivaccine website like The International Medical Council on Vaccination or Generation Rescue or the antivaccine blog Age of Autism. Look at quack websites like NaturalNews.com The comparison, at least when it comes to web and blog design, is not flattering…..

New research center in Madagascar opens today

Mireya Mayor and Patricia Wright

Mireya Mayor and Patricia Wright

Today, renowned primatologist Dr. Patricia Wright, and the Prime Minister and the Minister of Higher Education of Madagascar will unveil and open NamanaBe Hall (which translates as Friendship Hall) – a new research, arts and community outreach building in Ranomafana, Madagascar.

The 1,440 square meter building is as ‘green’ as can be – built out of local materials (locally-sourced granite, brick, and eucalyptus flooring), with work by local artisans and craftsmen, it has gardens and solar panels on the roof, gray water recycling, solar hot water, natural cooling, and enhanced use of daylight. Apart from it being sustainable, it is also hoped to provide an example to local (and global) populations on how to employ “green” techniques in building design and construction.

Centre Valbio by Dede Randrianarista

Centre Valbio by Dede Randrianarista

NamanaBe Hall is the newest addition to Stony Brook University’s research center – Centre ValBio – built in 2003 to help indigenous people and the international community with conservation in Madagascar. It is a center of research in biodiversity, and also a community center for arts, environmental outreach, conservation education, and economic development of the region of the Ranomafana National Park. With the addition of NamanaBe Hall, Centre ValBio will become the largest, most modern, and most important research hub in Madagascar.

Construction of Namanabe Hall by Noel Rowe.

Construction of Namanabe Hall by Noel Rowe.

The new hall will have a conference room for 80 people, a computer training lab and library, an audiovisual office, dormitories, and a modern, sophisticated scientific laboratory equipped to study biodiversity (genetics, hormones and parasites) and infectious diseases. The whole campus will be equipped with high speed internet. In one word – perfect setting for a ScienceOnlineMadagascar 😉

During the opening ceremony, the founder of the Centre ValBio, Dr. Patricia Wright will receive a Commander National Medal of Honor.

Pat Wright with the villagers. Photo by Mitch Irwin.

A world-renowned primatologist, Dr. Wright is a McArthur Genius Fellow and will now be the first recepient of all three major medals that Malagasy government can give. The first is the Chevalier Medal of Honor. To get this high honor one must have done exceptional deeds in one’s field. If one accomplishes a second exceptional deed or work one can receive the Officier Medal eight to ten years after the Chevaliar. The third medal, the Commander, can only be awarded five years after the Officier and denotes a person who has done honorable and exceptional work throughout their careers.

The Medals of Honor are awarded to person’s of high achievement, who are creative and have contributed exceptionally to the country of Madagascar. Dr. Wright will now be the first recipient of all three, for her 26 years of conservation work to advance Malagasy biodiversity. Grammy-award winning Malagasy brand Tarika Be (voted by Time Magazine as one of the “10 Best Bands in the World” alongside U2 and Radiohead) will perform at the inauguration.

Thanks to Mireya Mayor and Stony Brook University for heads-up and information.

 

The Scienceblogging Weekly (June 29th, 2012)

Blog of the Week:

This week’s choice was easy – March of the Fossil Penguins, written by Dr. Daniel Ksepka. What is there not to like? Penguins! Fossils! Straight from the keyboard of the leading world expert on the topic. Enjoy!

 

Top 10:

How presidential elections are impacted by a 100 million year old coastline by Craig McClain:

Hale County in west central Alabama and Bamberg County in southern South Carolina are 450 miles apart. Both counties have a population of 16,000 of which around 60% are African American. The median households and per capita incomes are well below their respective state’s median, in Hale nearly $10,000 less. Both were named after confederate officers–Stephen Fowler Hale and Francis Marion Bamberg. And although Hale’s county seat is the self-proclaimed Catfish Capitol, pulling catfish out of the Edisto River in Bamberg County is a favorite past time. These two counties share another unique feature. Amidst a blanket of Republican red both Hale and Bamberg voted primarily Democratic in the 2000, 2004, and again in the 2008 presidential elections. Indeed, Hale and Bamberg belong to a belt of counties cutting through the deep south–Mississippi, Alabama, Georgia, South Carolina, and North Carolina–that have voted over 50% Democratic in recent presidential elections. Why? A 100 million year old coastline….

The Curious Case of the Poisoned Cows by Deborah Blum:

On a bright morning in early June, a Texas rancher named Jerry Abel turned his small herd of cattle out to graze. The 18 cows moved hungrily into that field of fresh grass. Within a few hours, only three were still alive. Abel’s 80 acre ranch sits just a little east of Austin and the story was strange enough that on Sunday a local CBS affiliate picked it up. “There was nothing you could do,” Abel told KEYE about his desperate efforts to save the animals. “Obviously, they were dying.”…

In the Steps of a Hungry Acrocanthosaurus by Brian Switek:

Compared to mounted dinosaur skeletons, fossil footprints might seem like mundane objects. They only record one small part of a fantastic creature, and it is harder to envision a whole dinosaur from the ground up than the wrap flesh around a skeletal frame. But we should not forget that dinosaur footprints are fossilized behavior—stone snapshots of an animal’s life. And sometimes, trackways record dramatic moments in dinosaur lives….

When It Comes to Numbers, We’re All Late Bloomers by Elizabeth Preston:

Good news for aspiring jelly-bean jar estimators who are under 30! Your intuitive grasp of numbers may not have peaked yet. Unlike other cognitive skills, the ability to approximate keeps improving well into adulthood. Since the skill is tied to mathematical smarts, this news might bring hope to struggling students….

June 8, 2012, Cedaredge Colorado—It was an ordinary Friday afternoon. I was at my desk writing when I looked out the window and saw an enormous plume of smoke billowing from the back of our property. It was the kind of moment when you’re supposed to remain calm and remember all the wise things you learned in first aid class or girl scouts. (Stop! Drop! Roll!) Instead, I panicked.

Plague at the Siege of Caffa, 1346 by Michelle Ziegler:

The first stage of the Black Death among Europeans was said to begin with the whoosh of a Mongol trebuchet. Gabriele De’ Mussi, a lawyer from near Genoa writing in about 1348, is believed to have recorded the account of the earliest use of plague as weapon of war at Caffa in 1346….

New flu gene found hiding in plain sight, and affects severity of infections by Ed Yong:

I could write the entire genome of a flu virus in around 100 tweets. It is just 14,000 letters long; for comparison, our genome has over 3 billion letters. This tiny collection of genetic material is enough to kill millions of people. Even though it has been sequenced time and time again, there is still a lot we don’t know about it….

‘Man-sheep-dog’: inter-species social skills by Paul Keil and Greg Downey:

Paul, the lead author, interviewed sheepdog trialer Damian Wilson about his interactions with his dog, a border collie named Yandarra Whiskey. Damian and Whiskey gave Paul a demonstration of the techniques used in sheepdog competitions as they together tried to move a mob of three sheep. In a competition in New South Wales, a trainer and dog have to move three sheep who have never been herded through a difficult obstacle course, and the trainer loses points if he (or, less frequently, she) breaks from a slow, measured pace walking the course. The rules mean that the dog itself must be trained until it anticipates the sheep’s reactions, and understands, on some level, what dog and trainer, together, are trying to accomplish. Although the trialer may give commands, the dog, too, is a kind of expert….

Preview: 3-D Space Shuttle Movie Will Bring the Launch Pad to Your Living Room by Tanya Lewis:

If you missed the final launch of the Space Shuttle, or the first private spacecraft rendezvous with the International Space Station, fear not. A new documentary to be released late this year promises you a fiery, 3-D, launch-pad view of these historic flights…

A Wartime Medical Dispenser by Jaipreet Virdi:

The Napoleonic Wars brought John Harrison Curtis’ studies to a standstill, as he became one of thousands of young men conscripted to fight against Napoleonic advances towards Britain. With his medical learning in hand, Curtis enlisted in the Royal Navy in 1808, to obtain his qualifications as surgeon and extend his medical skills. Since 1745, the Royal College of Surgeons in London, Edinburgh and Dublin, and the Navy held close associations with each other as the College was responsible for examining naval surgeons for active service. To be admitted as surgeon in the navy, candidates had to obtain a certificate of competence from the College and then be subjected to a two-hour oral examination at Somerset House….

The Scienceblogging Weekly (June 22nd, 2012)

Blog of the Week:

Like clockwork, almost every day for more than two years, Tommy Leung and Susan Perkins bring you Parasite of the Day. Sometimes gross, but always fascinating. And considering how most of us don’t pay much attention to parasites these days, there is something cool to learn every single day.

 

Top 10:

The only good abortion is my abortion by Maggie Koerth-Baker:

…Of course, we don’t call it an abortion. We call it “a procedure” or a D&C. See, my potential abortion is one of the good abortions. I’m 31 years old. I’m married. These days, I’m pretty well off. I would very much like to stay pregnant right now. In fact, I have just spent the last year—following an earlier miscarriage—trying rather desperately to get pregnant…

Defending Jonah Lehrer by Bradley Voytek (about criticisim of neuroscience, not “self-plagiarism”):

Cognitive neuroscience grew out of experimental psychology, which has decades of amazing observations to link psychology and behavior. But with this legacy comes a lot of baggage. Experimental psychologists observed that we have the capacity for memory, attention, emotion, etc. and they sought to piece those phenomena apart. With the advent of neuroimaging techniques, psychologists put people in brain scanners to see where in the brain behaviors “were”. But this is the wrong way of thinking about these concepts.

The genius myth by Zen Faulkes:

…This myth of destiny and inevitable triumph of genius is, to me, completely the opposite of what science is. The scientific method leveled the playing field for discovering truth. Anyone could follow the methods and get to the bottom of things, so truth was no longer subject to tricky things like personal revelation….

Climate change is simple: We do something or we’re screwed by David Roberts:

…The challenge I took on was to convey the gist of my “brutal logic of climate change” post in a reasonably short amount of time, using as little scientific jargon as possible. Just: there is a problem that calls for urgent action. Business-as-usual means disaster. This is all gloom and doom — not even much humor. I know that turns people off or shuts them down. I know people need to feel a sense of hope and efficacy. I know — indeed, have recently been writing — that we need a vision of a sustainable future. But I needed to do my own version of “Danger Will Robinson!” Just to get it on the record…

Tunes without composers: music naturally evolves on DarwinTunes by Ed Yong:

…The tunes embedded above weren’t written by a composer, but fashioned through natural selection. They are the offspring of DarwinTunes, a program which creates bursts of noise that gradually evolve based on the preferences of thousands of human listeners. After hundreds of generations, tracks that are boring and grating soon morph into tunes that are really quite rhythmic and pleasant (even if they won’t be topping charts any time soon)….

Snake-eating beetles by Andrew Durso:

So little is known about the parasites of snakes that we tend to discount them all together, but the ecological and evolutionary interactions between hosts and their parasites can be very strong. This is a story about how two enterprising snake biologists solved a mystery that had been puzzling entomologists for decades…

Test-Tube Piggies: How did the guinea pig become a symbol of science? by Daniel Engber:

…To call someone or something a guinea pig may suggest a mere experiment (“Joe Biden was put out as a guinea pig for the White House”), or it can invoke the specter of exploitation (the U.S. Army wanted “to use young men as guinea pigs and throw them away”). The image either describes the scientific process or condemns it. It’s a totem or a scarecrow. What makes this wording more curious is the fact that guinea pigs, real ones, don’t mean much to working scientists. For all their rhetorical importance, the animals scarcely register in the lab…

What’s changed in evolution and ecology since I started my Ph.D. by Jeremy Yoder:

Last month, I filed my PhD dissertation, bringing to an end an intellectual and personal journey that began seven years ago in the summer of 2005. I know a lot more now than I did then, and I know a lot more about the boundaries of what I don’t know, too. But not only has my knowledge changed—evolution and ecology looks a lot different now than it did seven years ago when I was planning my dissertation research. At some point, and often multiple points, in the process of getting a PhD, everybody wonders whether what they’re doing is already out of date. Some of the transformations in the field I think I could see coming. For instance, it was clear in 2005 that computational power would keep increasing, phylogenetics would be used more and more to ask interesting questions, more and more genomes would be available for analysis, and evolutionary developmental biology was on the rise. It was unfortunately also predictable that it would be possible to study climate change in real time over PhD-length timescales. And although the 2008 global financial crisis didn’t help, it was clear that funding and jobs were going to be more competitive than they had been for our predecessors….

Drawing sharp boundaries in a fuzzy world by Chris Rowan:

Humans are natural splitters. We have an innate tendency to look at the world and mentally sort everything into different categories, and grades, and entities: this is one thing, that is another; it was this, now it’s that. Our perception of colour is a good example of how our brains automatically split a continuum into discrete boxes. We’ve incorporated our love of classification deep into science, trying to formalise and quantify the dividing lines we want to draw on everything: it’s this when conditions A and B are met, it’s that when we see Y and Z. But nature doesn’t often make it easy for us to draw our sharp dividing lines….

Why the Scientist Stereotype Is Bad for Everyone, Especially Kids by Michael Brooks:

To many – too many – science is something like North Korea. Not only is it impossible to read or understand anything that comes out of that place, there are so many cultural differences that it’s barely worth trying. It’s easier just to let them get on with their lives while you get on with yours; as long as they don’t take our jobs or attack our way of life, we’ll leave them in peace…

The Scienceblogging Weekly (June 15th, 2012)

Blog of the Week:

Russ Williams is the Director of the North Carolina Zoological Society and, as far as I know, the only “director of a zoo” who blogs. And does he ever – Russ has been blogging up a storm ever since 2005 when Ed Cone taught him how (you may call me The Blogfather, but Ed Cone is the blogfather for many of us in North Carolina). On his blog Russlings, Russ covers plenty – what is new at the N.C.Zoo in Asheboro, what is new in other zoos around the country and the world, what is new in policy and politics of animal conservation, plus cool pictures and videos of wildlife. But where the value really comes up is at the times of natural disasters – Russ is “in the know” and often the first and/or the only person to blog about the status of zoos and aquaria, as well as farm animals, wildlife preserves etc, in the affected areas. During disasters, Russlings is the Go-To place for such coverage.

 

Top 10:

How Our Disinterest in ‘The Environment’ Signals the End of Nature by Christopher Mims:

No one reading this has the slightest fucking clue what “nature” is, and in 1995 fisheries scientist Daniel Pauly proved it. In the paper that introduced the term “shifting baselines,” Pauly described how experts who determined how many fish should be caught often started with whatever the baseline state of the ecosystem was when they started their careers, instead of considering what a fishery might have looked like in the past, when it wasn’t nearly as degraded….

Getting used to being in charge of the planet by David Roberts:

…Nonetheless, like evolution, the dominance of human beings on Spaceship Earth is a profound and terrifying threat to all sorts of traditional worldviews. If Darwin showed us that God is not our author, the Anthropocene shows that He is not our caretaker. There’s no parent to supply us with endless resources and endless room to dispose of our waste. There’s no one to protect us or prevent us from screwing it all up….

Walking the Line: How to Identify Safe Limits for Human Impacts on the Planet by David Biello:

Is preserving the general environmental conditions that allowed civilization to flourish—a moderate climate, a rich array of species, rivers that reach the sea—necessary to ensure humanity endures? Or is minimizing alterations to the global environment introduced by human activity—rising levels of CO2 from fossil-fuel burning, widespread extinction, dams that impound water—more important to our success? Choosing the right approach is vital as the scale of human impact on the planet becomes so large that scientists are calling this new epoch in Earth’s history the Anthropocene (when human activity alters global climate and ecosystems)…

#GMOFAQ: Transferring genes from one species to another is neither unnatural nor dangerous by Michael Eisen:

Last week I wrote about the anti-science campaign being waged by opponents of the use of genetically modified organisms in agriculture. In that post, I promised to address a series of questions/fears about GMOs that seem to underly peoples’ objections to the technology. I’m not going to try to make this a comprehensive reference site about GMOs and the literature on their use and safety (I’m compiling some good general resources here.) I want to say a few things about myself too…

Sea level rise 101 by John Bruno:

Based on the NC legislature’s decree about the science of sea level rise projections and some of the related propaganda we have seen from climate change deniers, I get the sense there is a lot of confusion about sea level rise. So here is a primer on what we know about sea level and climate change…

Dirty soil and diabetes: Anniston’s toxic legacy by Brett Israel:

The Rev. Thomas Long doesn’t have neighbors on Montrose Avenue anymore. Everyone is gone. Widespread chemical contamination from a Monsanto plant was discovered in this quiet city in the Appalachian foothills back in the 1990s. In West Anniston, behind Long’s home, a church was fenced off, and men in “moon suits” cleaned the site for weeks. Nearby, boarded windows and sunken porches hang from abandoned shotgun houses. Stray dogs roam the narrow streets. A red “nuisance” sign peeks above the un-mowed lawn of one empty house. Bulldozers will be here soon…

Pollution, Poverty, People of Color: No beba el agua. Don’t drink the water. by Liza Gross

Jessica Sanchez sits on the edge of her seat in her mother’s kitchen, hands resting on her bulging belly. Eight months pregnant, she’s excited about the imminent birth of her son. But she’s scared too. A few feet away, her mother, Bertha Dias, scrubs potatoes with water she bought from a vending machine. She won’t use the tap water because it’s contaminated with nitrates…

The crayola-fication of the world: How we gave colors names, and it messed with our brains (part II) by Aatish Bhatia:

Lately, I’ve got colors on the brain. In part I of this post I talked about the common roads that different cultures travel down as they name the colors in their world. And I came across the idea that color names are, in some sense, culturally universal. The way that languages carve up the visual spectrum isn’t arbitrary. Different cultures with independent histories often end up with the same colors in their vocabulary. Of course, the word that they use for red might be quite different – red, rouge, laal, whatever. Yet the concept of redness, that vivid region of the visual spectrum that we associate with fire, strawberries, blood or ketchup, is something that most cultures share….

How the Chicken Conquered the World by Jerry Adler and Andrew Lawler:

The chickens that saved Western civilization were discovered, according to legend, by the side of a road in Greece in the first decade of the fifth century B.C. The Athenian general Themistocles, on his way to confront the invading Persian forces, stopped to watch two cocks fighting and summoned his troops, saying: “Behold, these do not fight for their household gods, for the monuments of their ancestors, for glory, for liberty or the safety of their children, but only because one will not give way to the other.” The tale does not describe what happened to the loser, nor explain why the soldiers found this display of instinctive aggression inspirational rather than pointless and depressing. But history records that the Greeks, thus heartened, went on to repel the invaders, preserving the civilization that today honors those same creatures by breading, frying and dipping them into one’s choice of sauce. The descendants of those roosters might well think—if they were capable of such profound thought—that their ancient forebears have a lot to answer for….

‘Sexual depravity’ of penguins that Antarctic scientist dared not reveal by Robin McKie:

It was the sight of a young male Adélie penguin attempting to have sex with a dead female that particularly unnerved George Murray Levick, a scientist with the 1910-13 Scott Antarctic Expedition. No such observation had ever been recorded before, as far as he knew, and Levick, a typical Edwardian Englishman, was horrified. Blizzards and freezing cold were one thing. Penguin perversion was another….

The Scienceblogging Weekly (June 8th, 2012)

Wow – this was hard! I could have had at least Top 20 instead of Top 10 (but you’ll find them all listed down there anyway)…

 

Blog of the Week:

Tanya Khovanova’s Math Blog is a blog by Tanya Khovanova, a Visiting Scholar and Research Affiliate at MIT, a 1976 gold medalist (and 1975 silver medalist) at the International Mathematics Olympiad. What she does the most (though there is occasionally other stuff there) is to pose difficult (and some not to so difficult) mathematical problems and puzzles for her readers to try to solve in the comments. Go ahead and give it a try yourself!

 

Top 10:

Sea Level Rise Is Tied to Prevalence of Homosexuality by Craig McClain:

Although only two years old and previously unrecognized by the scientific establishment, Global Draining (GD) has now become a widely accepted theory. GD states that sea level is falling not rising (Southern Fried Science, 2010a). Current rates of GD indicate the entire world’s ocean will be empty by 2026 (Southern Fried Science, 2010a). Local-scale observation of in situ draining combined with a robust theoretical model firmly place the rate of draining at 40 Gigatons of water per year (Dr. M, 2010). It has been argued that both one and multiple holes occur in the ocean floor that allow for GD (i.e. the monoclavis versus polyclavis hypotheses via McCay, 2010; Southern Fried Science, 2010b). However, the impacts and causes of GD are not clearly understood. Despite this, GD is a fundamental tenet of nearly every facet of science and likely correlated with many aspects of biology, economics, sociology, religion, and politics. For example, GD is likely to lead to massive die offs of sharks and reduce global atmospheric oxygen levels (Shark Diver, 2010)…

The crayola-fication of the world: How we gave colors names, and it messed with our brains (part I) by Aatish Bhatia:

In Japan, people often refer to traffic lights as being blue in color. And this is a bit odd, because the traffic signal indicating ‘go’ in Japan is just as green as it is anywhere else in the world. So why is the color getting lost in translation? This visual conundrum has its roots in the history of language…

Arsenic Life Wrap-Up: The Good, the ‘Not-So-Good’ by See Arr Oh:

“Arsenic Life,” a hot-button issue for much of the past year, reemerged this week with two new papers, one propitious, and one, well…not so much….

In defense of frivolities and open-ended experiments by Bradley Voytek:

My first child was born just about nine months ago. From the hospital window on that memorable day, I could see that it was surprisingly sunny for a Berkeley autumn afternoon. At the time, I’d only slept about three of the last 38 hours. My mind was making up for the missing haze that usually fills the Berkeley sky. Despite my cloudy state, I can easily recall those moments following my first afternoon laying with my newborn son. In those minutes, he cleared my mind better than the sun had cleared the Berkeley skies…

Women’s Work by Virginia Hughes:

I write mostly about neuroscience, genetics and biotechnology. That means I spend most of my time talking to and writing about men.

In May of 2011 (chosen arbitrarily just because it was a year ago and I’m pretty sure I wasn’t thinking about this gender gap then), 89 percent of my phone interviews were with men.

I can think of a few reasons for this…

The Mechanics and Meaning of That Ol’ Dial-Up Modem Sound by Alexis Madrigal:

Of all the noises that my children will not understand, the one that is nearest to my heart is not from a song or a television show or a jingle. It’s the sound of a modem connecting with another modem across the repurposed telephone infrastructure. It was the noise of being part of the beginning of the Internet…

I’m not a speciesist, but… by Jack Scanlan:

Is it a paradox to hate your own species? Is such a feeling the product of a broken and conflicted mind? Or could it perhaps be the signature of psychopathy? Every day these questions run through my mind and I feel guilty. Why? Well, because I do hate my own species. Homo sapiens is terrible, and I’m surprised more people don’t recognise this…

The science and ethics of voluntary amputation by Mo Costandi:

…In January 2000, the mass media ran several stories about Robert Smith, a surgeon at the Falkirk and District Royal Infirmary who had amputated the legs of two patients at their own request and was planning a third amputation. The news stories incorrectly described the patients as suffering from Body Dysmorphic Disorder. They further stated that the director of NHS trust running the hospital at which Smith works described the amputation of healthy limbs as “inappropriate”; since then, no British hospital has performed a voluntary amputation…

In Defense of Mickey Mouse Science by Byron Jennings:

…I suppose one could hook up the computers directly to the experiments and have them generate models, test the models against new observations and then modify the experimental apparatus without any human intervention. However, I am not sure that would be science. Science is ultimately a human activity and the models we produce are products of the human mind. It is not enough that the computer knows the answer. We want to have some feeling for the results, to understand them. Without the simple models, Mickey Mouse science, that would not be possible: the big news made ever so small…

From plaster to programming: How borrowed technologies are changing paleontology by Justine E. Hausheer:

In popular culture, paleontologists are like Indiana Jones. Rugged men wandering through rocky deserts, wearing wide-brimmed leather hats and multi-pocketed khaki vests. Rock-hammers hang nonchalantly from their belt-loops, maps and note-pads protrude from pockets. On a whim, they brush aside some sand to reveal a ferocious skull and massive vertebrae, and then they puzzle out the mysteries of dinosaurs just by staring at the rocks. But in contemporary science, paleontologists are biologists, computer programmers, and engineers…

The Scienceblogging Weekly (June 1st, 2012)

Blog of the Week:

Vintage Space is a blog by Amy Shira Teitel, science writer and historian of space exploration living in Arizona. She has been busy lately, contributing articles to Discovery News, Motherboard, Spaceflight Observer podcasts, Scientific American Guest Blog, Soapbox Science blog, Timeline Magazine, AmericaSpace and Universe Today, among else. Vintage Space is her writing laboratory, where she first explores topics she may subsequently expand into longer pieces for other venues. And she links to all of her articles as they go live in various places so you can keep up with her prolific output. Those of you regular readers of Scientific American blogs may remember her guest posts, and for those of you not familiar, those can give you the taste of her fascinating forays into the history of space: Sky Crane – how to land Curiosity on the surface of Mars and Apollo 1: The Fire That Shocked NASA and John Glenn: The Man Behind the Hero.

Top 10:

Nicotine and the Chemistry of Murder by Deborah Blum:

The 1850 murder of Gustave Fougnies in Belgium is not famous because of the cleverness of his killers. Not at all. They – his sister and brother-in-law – practically set off signal flares announcing their parts in a suspicious death.

It’s not famous because it was such a classic high society murder. The killers were the dashing, expensive, and deeply indebted Comte and Countess de Bocarmé. The death occurred during a dangerously intimate dinner at their chateau, a 18th century mansion on an estate in southern Belgium.

Nor it is remembered because the Comte died by guillotine in 1851 – so many did after all.

No, this is a famous murder because of its use of a notably lethal poison. And because the solving of this particular murder changed the history of toxicology, helped lay the foundation for modern forensic science. The poison, by the way, was the plant alkaloid nicotine….

Richard Dawkins, Edward O. Wilson, and the Consensus of the Many by David Sloan Wilson:

…I mean Dawkins and Wilson no disrespect by calling them two among many. I trust that they would agree and would defer to others especially when it comes to mathematical models, which is not their area of expertise. If the public is going to become literate on the issues at stake—as well they should, because they are fundamental to the study of human sociality—then they will need to realize that both Wilson and Dawkins get some things right and other things wrong. Moreover, the entire community of scientists is in more agreement than the infamous exchange in Nature seems to indicate. Taking the argument from authority seriously can lead to a breakthrough in the public’s understanding of social evolution. …

The protein makes the poison: Dancing fruit flies and terfenadine by Ashutosh Jogalekar:

…Dose-specific toxicity is indeed of paramount importance in medicine, but if you delve deeper, the common mechanism underlying the toxicity of many drugs often has less to do with the specific drugs themselves and more to do with the other major player in the interaction of drugs with the human body – proteins. Unwarranted dosages of drugs are certainly dangerous, but even in these cases the effect is often mediated by specific proteins. Thus in this post, I want to take a slightly different tack and want to reinforce the idea that when it comes to drugs it’s often wise to remember that “the protein makes the poison”. I want to reinforce the fact that toxicity is often a function of multiple entities and not just one. In fact this concept underlies most of the side-effects of drugs, manifested in all those ominous sounding warnings delivered in rapid fire intonations in otherwise soothing drug commercials…

The trouble with brain scans by Vaughan Bell:

Neuroscientists have long been banging their heads on their desks over exaggerated reports of brain scanning studies. Media stories illustrated with coloured scans, supposedly showing how the brain works, are now a standard part of the science pages and some people find them so convincing that they are touted as ways of designing education for our children, evaluating the effectiveness of marketing campaigns and testing potential recruits…

Cloaking the rainbow by Rose Eveleth:

Invisibility cloaks aren’t just for Harry Potter anymore. Last year, researchers made one that cloaked things in time. Now they’ve made thousands of tiny invisibility cloaks that trap a rainbow. That’s right, 25,000 invisibility cloaks trapping a rainbow. The first question you might be asking is: why? Why does it take 25,000 invisibility cloaks to trap a rainbow? Or maybe, why trap a rainbow in the first place?

An Analysis of Blaster Fire in Star Wars by Rhett Allain:

You have no idea how long I have been planning to look at the blasters in Star Wars. No idea. Finally, the 35th Anniversary of Star Wars has motivated me to complete my study (which I haven’t actually started). Here is the deal: What are these blasters? How fast are the blaster bolts? Do the blasters from the spacecraft travel at about the same speed as the handheld blasters? Why do people still think these are lasers?…

Don’t worry so much about being the right type of science role model by Marie-Claire Shanahan:

What does it mean to be a good role? Am I a good role model? Playing around with kids at home or in the middle of a science classroom, adults often ask themselves these questions, especially when it comes to girls and science. But despite having asked them many times myself, I don’t think they’re the right questions…

Evolutionary psychology: A dialogue by Jeremy Yoder:

A Biologist went down to the coffee shop one day, because the walk out to the edge of the University campus provided some brief respite from the laboratory. Along the way the Biologist encountered an Evolutionary Psychologist, who was also going to the coffee shop, and they fell to walking together…

How I Stopped Worrying (about science accuracy) And Learned to Love The Story by Phil Plait:

When I was a kid – and who am I kidding; when I was an adult too – I made fun of the science in movies. “That’s so fakey!” I would cry out loud when a spaceship roared past, or a slimy alien stalked our heroes. Eventually, my verbal exclamations evolved into written ones. Not long after creating my first website (back in the Dark Internet Ages of 1997) I decided it would be fun to critique the science of movies, and I dove in with both glee and fervor. No movie was safe, from Armageddon to Austin Powers…

The Fantastic Gliding Stegosaurus by Brian Switek:

Stegosaurus is undoubtedly one of the most perplexing dinosaurs. What was all that iconic armor for? (And how did amorous stegosaurs get around that complication?) Paleontologists have been investigating and debating the function of Stegosaurus ornamentation for decades, but without much consensus. The dinosaur’s spectacular plates were certainly prominent visual signals, but could they also have been used for regulating body temperature? Or might there be some evolutionary impetus we’re not thinking of?

Clocks, metabolism, evolution – toward an integrative chronobiology

The biannual meeting of the Society for Research on Biological Rhythms happened last week. Unfortunately, I could not attend, so will have to wait another two years for the next opportunity.

I am not sure how this stuff happens, but there was a flurry of new papers in the circadian field just preceding the event. Several of them have already received quite a lot of attention in both old and new media, and rightfully so, but I decided not to cover them one at a time just as the embargo lifted for each one of them.

Instead, I will just very briefly describe and explain the main take-home messages of each one of them, link to the best coverage for those who want more detail (“Cover what you do best. Link to the rest.“), and then try to come up with more of a ‘big picture’ summary of the current state of the field.

I apologize in advance for covering and linking to some of the papers that are not published in Open Access journals. I am not as strict about this policy as some other bloggers are (“if my readers cannot access it, they cannot fact-check me”), and will occasionally cover non-OA papers. Even if most of my readers cannot access them, I gather that a miniscule proportion can access and, if I got something wrong, can alert the other readers in the comments. And speaking of Open Access, I am not one to sign many online petitions, but this one is worth it so please sign if you have not done it already.

So, let’s see what new and exciting in chronobiology these days…

Article: Ben Collins, Elizabeth A. Kane, David C. Reeves, Myles H. Akabas, Justin Blau, Balance of Activity between LNvs and Glutamatergic Dorsal Clock Neurons Promotes Robust Circadian Rhythms in Drosophila, Neuron, Volume 74, Issue 4, 706-718, 24 May 2012

What is it about: Robustness of daily rhythms and their flexible, adaptive responses to the environment, require a feedback loop between a cluster of clock cells in the brain and another cluster of non-clock cells in the brain of Drosophila melanogaster.

What is new: Feedback loops between two or more brain centers (or tissues, or organs) as necessary for either existence of some circadian rhythms, or for the rhythms’ robustness and fine-tuned response to the environment, have been studied mostly in vertebrates, especially birds and lizards, and to some extent mammals. Such feedback loops have been found in the fruitfly as well. This paper finds out a lot of detail about this feedback loop, including the use of glutamate as a neurotransmitter in one half of the loop. As Drosophila is still the lab organism with the most developed techniques for precise genetic manipulations, this is an important advance.

Take-home message: How core clock genes turn each other on and off within a cell over 24 hours is just the beginning, a small part of the story. To work properly, to be adaptive, and to respond well to environmental cues, circadian rhythms require organization at a higher level, with fine-tuned communication among clock-cells and between clock and non-clock tissues.

Some more thoughts: This is a technical tour-de-force. Fruitfly genetics techniques today are so powerful and this paper appears to use them all: inserting, deleting, downregulating and upregulating genes of choice in precisely targeted cells in the brain. As every behavioral biologist knows, once introduced into an experiment animals do whatever the heck they please. The behavior measured in this paper was a simple light-avoidance test – fruitfly larvae (and in the last experiment, also adults) are placed in a petri dish that is half in light, half in darkness, and the movement and position of the larvae is monitored. Considering how messy such behavioral data tend to be, the results in this paper are quite impressive.

The Abstract/Summary, the Introduction, and the (far too short) Discussion are very clear, straighforward and easy to read and understand. They are also upfront and direct about their main take-home message. The many pages in-between, though, are clearly meant to be read only by Drosophila clock geneticists who can actually wade through the essentially endless litany of acronyms in hope of replicating or following up on this study. Clocks are my field, but I am not a geneticist or drosophilist, so much of the Materials & Methods and Results sections in this paper are over my head. Maddeningly, some of the most important stuff is hidden in the Supplemental Materials, including this model for how the whole thing works (shouldn’t this image be up front, on the top of the whole thing?):

Note: If I remained in research, I would have done something like this, not necessarily in fruitflies, but definitely looking at neural networks, feedback loops and higher-level organization of the circadian system, within ecological and evolutionary contexts. This may bias me toward liking this paper as much as I do.

EVOLUTION

Article: Rachel S. Edgar et al., Peroxiredoxins are conserved markers of circadian rhythms, Nature, Published online 16 May 2012, doi:10.1038/nature11088

What is it about: A protein (peroxiredoxin) that is found in almost all living organisms has two states/conformations that cycle at approximately 24 hours. Presence and proper function of core circadian clock genes is not necessary for the cycling of this protein. An Archea species that does not live on the surface does not have the clock and does not have this protein.

What is new: This finding in human red blood cells and a Protist (O.tauri) was published last year. This paper adds similar data for a whole bunch of other organisms: cyanobacteria, archaea, fungi, plants, insects and vertebrates.

Take-home message: There are really two take-home messages, one physiological, one evolutionary. First, this demonstrates that circadian clocks are properties of the entire cells (or assemblages of cells in case of multicellular organisms), not just the transcription/translation loops of core clock genes.

Second, the protein in question, the peroxiredoxin, could be akin to “scaffolding”, something that allows a cell to keep cycling while genes come and go, mutate and change and duplicate, while being fine-tuned by natural selection. Over billions of years, this can result in major groups of organisms (e.g., animals vs. plants vs. fungi vs. bacteria, vs. several different groups of protists) having entirely different circadian genes, yet all of them using the same “logic” (transcription/translation feedback loops).

Both the peroxiredoxins and the circadian clocks are thought to have originated as defense from UV radiation of the early oceanic surfaces (Pittendrigh, C.S., 1967. Circadian rhythms, space research, and manned space flight. In: Life Sciences and Space Research 5:122-134. North-Holland, Amsterdam.), or defense against other kinds of demage, including that from oxidation, so it makes sense that they co-originated and co-evolved only once in the history of the planet, perhaps around 2.5 million years ago when photosynthetis bacteria introduced lots of molecular oxygen into the Earth’s atmosphere. It also makes sense that they both are missing in organisms that have never lived close to the oceanic or terrestrial surface (e.g., many Archaea).

Essential reading: When the two papers (on red blood cells and the protists) came out last year, I wrote a very comprehensive post that places this research direction into historical, philosophical, methodological and even media context. There is not much in that post that would change with the publication of this new paper apart from additional confirmation in several new species. So just go and read it again.

Some more thoughts: Peroxiredoxins cycle in all kinds of different cells with an approximately 24 hour period. This makes them, almost by definition, circadian clocks. Last year’s papers also show that the peroxiredoxin clock dominates its phase over the clock driven by core circadian genes. But there is something still to find out, and it is important: can the peroxiredoxin clock drive any other rhythms? For it to work as a biological pacemaker, it is not sufficient for it to cycle itself, it also need to drive timing of other events in the cell (and the entire organism). I am assuming that this research group will look at this problem next.

Mammals have six peroxiredoxin genes. In an experiment (Zhang et al., Cell , 2009), human cell lines were engineered in such a way that each culture had a different peroxiredoxin gene knocked out. None of the knock-outs had any effect on the regular circadian expression of the core clock gene Bmal1. Of course, having six genes indicates redundancy in function. One would need to knock out all six simultaneously in order to see an effect on other rhythms in the cell, but there is a question if cells with all peroxiredoxins knocked out can survive at all. Someone should try this.

Also, that experiment was done in mammalian cells. Mammals are probably the worst model system for studying this question. Vertebrates have undergone several events of gene (and genome) duplication, and mammals got at least another one. If you look at mammals, every clock gene exists in multiples (e.g,. Per1, Per2, Per3). Poor peroxiredoxin probably cannot do much in such a massively genetically determined system.

Gene duplication allows for evolutionary experimentation. As long as one copy of the gene keeps working, the others are free to mutate. Some mutations will be selected against (e.g., if they mess up the clock function) and others will be selected for (e.g., if they fine-tune the circadian function, making it more flexible and adaptable, or start performing some other valuable function instead). This means that functions formerly in the domain of higher-level organization or the domain of phenotypic plasticity, are now under control of genes. This process is called Genetic assimilation (and sometimes Baldwin effect, though that term is usually reserved for genetic assimilation of learned behaviors). So it is quite possible that the clock in mammals is over-determined by genes, making it useless for the study of peroxiredoxins as scaffolding for circadian evolution.

If I was doing this research, I would stay away from these vertebrate oddballs for at least the next five or ten years, and focus my time, funds and energy on the study of bacteria, archaea, protists, fungi and perhaps some plants – smaller the genome the better.

Article: Faure, S., Turner, A.S., Gruszka, D., Christodoulou, V., Davis, S.J., von Korff, M. & Laurie, D.A. Mutation at the circadian clock gene EARLY MATURITY 8 adapts domesticated barley (Hordeum vulgare) to short growing seasons, Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.1120496109

What is it about: In barley cultivars from Northern Europe a mutation in a gene responsible for flowering feeds back on the circadian clock genes, greatly reducing the amplitude of the gene cycling, effectively shutting down the clock. Without proper clock function, barley does not use the clock to measure seasonal changes in daylength (photoperiodism) but instead matures at the fastest rate its development permits. This allows barley to mature and flower early in the season, as well as to photosynthetise throughout the long days of summer in the North.

What is new: Yet another organism in which some of the clock function is temporarily or permanently eliminated. Good news: unlike the other such organisms which tend to be not-well-studied inhabitants of extreme environments, barley is a domesticated plant, well researched and easy to use in the lab.

Take-home message: one has to be careful with interpreting studies like these – just because an organism does not show a couple of well-studied rhythms in physiology and behavior, and does not show cycling in expression of core clock genes does not mean that all circadian function is gone. Ensembles of cells, or feedback loops between tissues, or cytoplasmic factors like peroxiredoxin may still be working in the organism, it’s just that this cannot be detected with the techniques used in the study.

REPRODUCTION

Article: Summa KC, Vitaterna MH, Turek FW (2012) Environmental Perturbation of the Circadian Clock Disrupts Pregnancy in the Mouse. PLoS ONE 7(5): e37668. doi:10.1371/journal.pone.0037668 (Open Access)

What is it about: Female mice kept in 24 cycles get and remain pregnant easily. Female mice kept in rotating shifts (either advances or delays of the 24 hour cycle by 6 hours every several days) do not. Difference is striking!

What is new: Interactions between circadian rhythms and reproductive cycles have been studied for decades in many different organisms. Last year, a study with already pregnant mice moved to rotating shifts did not result in spontaneous losses of pregnancy. This study suggests that rotating shifts prevent pregnancy to begin in the first place, probably by interfering with implantation of the egg in the uterus.

Take-home message: Another example how clock is not just about timing of downstream events, but also plays part in them more directly. While this study was done in rodents, it works well together with epidemiological data from humans working on rotating shifts. As the light-dark cycle is shifted, the brain clock resets itself pretty quickly, over a period of a couple of days. But peripheral clocks in all the other organs will reset slower, each at its own rate. This include the ovaries, uterus etc, which may not be ready for egg implantation at the time of day when the brain send the relevant signal. In essence, internal desynchronization of clocks prevents all the parts of the system to work in synchrony – this is the main negative effect of jet-lag, and it applies to reproduction as much as it does to digestion and other functions.

Effect of entrainment on success of pregnancy

Some more thoughts: Both the paper and the media coverage are clear, straightforward and readable. But if one wanted to explain these data by building a formal/conceptual or mathematical model this could easily get mind-bogglingly complicated: one would have to take into account multiple feedback loops between repeatedly desynchronized oscillators, plus potential effects of photoperiodism.

Good coverage elsewhere: Sarah Fecht did a great job. Most of the rest of the media just regurgitated the press release. Oh, this was even covered by Daily Mail 😉

CANCER

Article: Johnni Hansen, Christina F Lassen, Nested case–control study of night shift work and breast cancer risk among women in the Danish military. Occup Environ Med doi:10.1136/oemed-2011-100240

What is it about: A large-scale study of Danish female soldiers found a higher incidence of breast cancer in those who had to work night shifts. Longer the period of night-shift work, greater the incidence. Also, early risers were more susceptible to this negative effect of night shift work.

What is new: Earlier studies were mostly done in nurses in the USA. This provides a much larger data-set of women followed over a long period of time in a different profession in a different country. Military environment also controls for many other aspects of life (food, quality of medical care, physical fitness, etc.) which tends to be more uniform than in the general population.

Take-home message: Prolonged night shift work, especially if you are an early bird, may be bad for your health.

Some more thoughts: Internal desynchronization between various body clocks, especially long-term, is bound to have negative consequences. Suffering from jet lag occasionally when traveling is fine. But getting jet-lagged every day for years is seriously impairing all sorts of body functions (see reproduction above).

METABOLISM

Article: Yuta Fuse, Akiko Hirao, Hiroaki Kuroda, Makiko Otsuka, Yu Tahara and Shigenobu Shibata, Differential roles of breakfast only (one meal per day) and a bigger breakfast with a small dinner (two meals per day) in mice fed a high-fat diet with regard to induced obesity and lipid metabolism. Journal of Circadian Rhythms 2012, 10:4 doi:10.1186/1740-3391-10-4 (Open Access)

What is it about: Three groups of mice were fed a high-fat diet, each group getting exactly the same amount of food each day (and eating it all up each day). One group had free access to food at all times (and ate all the time). The second group was given food in a limited time regimen: a large breakfast and a small dinner. The third group was given all the food to gobble up in one large brekfast. The group that got only a large breakfast got obese, had other metabolic problems and had a disrupted expression of circadian genes.

What is new: Another interesting paper showing that timing of meals determines how the food is processed by the body.

Take-home message: Eating one big meal per day is bad for your health – spread it out a little.

Some more thoughts: The paper is interesting as the data suggest something different from most of the other papers in this line of research (see the next two papers below).

Good coverage elsewhere: I could not find any.

Article: Megumi Hatori, Christopher Vollmers, Amir Zarrinpar, Luciano DiTacchio, Eric A. Bushong, Shubhroz Gill, Mathias Leblanc, Amandine Chaix, Matthew Joens, James A.J. Fitzpatrick, Mark H. Ellisman, Satchidananda Panda, Time-Restricted Feeding without Reducing Caloric Intake Prevents Metabolic Diseases in Mice Fed a High-Fat Diet. Cell Metabolism, 17 May 2012 doi:10.1016/j.cmet.2012.04.019

What is it about: Groups of mice were fed either normal or high-fat diet either with continuous free access to food or with feeding time limited to 8 hours during the night (remember that mice are nocturnal – this is their active period, i.e., their “day”). The results appear to be opposite from the paper above (by Fuse at al.) – it is the mice with unlimited feeding that got obese and developed metabolic problems, as well as reduced amplitude of the circadian gene expression.

What is new: Hmmm, which one of the two papers is “more right” than the other? The devil is in the details, so we’ll have to look there.

There are two obvious differences between the two papers. The Hatori paper gave full volume of the normal daily intake of food, while the Fuse paper gave mice only 80% of the normal food quantities per day – which is calory restriction in itself. This may explain why the free-feeding mice in Hatori paper got obese and developed problems, while the mice in the Fuse paper did not.

Second, there is a difference in timing of meals in time-restricted groups. There is “time-restricted feeding” and then there is “time-restricted feeding”! The Hatori paper restricted feeding to an 8-hour period starting one hour after lights-off and ending three hours before lights-on. The Fuse group gave breakfast at the moment of lights-off (the paper does not say for how long – presumably with reduced diet the hungry mice just ate it all very fast) and a smaller “dinner” at the moment of lights-on. These are very different timing schedules!

In many ways, the two-meal schedule of the Fuse paper is similar to the time-restricted schedule of the Hatori paper. Note that these two schedules did the best in regard to obesity and metabolism. Both the free-feeding (especially with the full diet in the Hatori paper) and extremely restricted feeding (brief but huge breakfast in the Fuse paper) resulted in bad metabolic effects. One can perhaps conclude that extremes are bad – one huge meal is bad as is continuous grazing, but that the spread of feeding over two or more smaller meals does better.

Take-home message: The perennial “more research is needed”….until then it is wise to eat your meals at normal times, more than once per day, no grazing in-between, and no midnight snacks…

Hatori image

Effect of feeding regimen on body weight and metabolism

Some more thoughts: Hatori paper is….overwhelming! There is so much work done. As I was reading it all, my thought was that ten pages in the middle of the paper could be completely cut out of the paper and the result would still remain exactly the same – just weigh the mice! All sorts of things were measured in a variety of ways, from gene expression patterns, to standard metabolic tests to histology. All that work strengthens the notion that obesity and metabolic problems are correlated, so the work is definitely not for nothing, and is very impressive. It certainly adds a lot of information to the notion that circadian clock is not just a timer, but intimately involved in regulation of metabolism.

Article: Till Roenneberg, Karla V. Allebrandt, Martha Merrow, Céline Vetter, Social Jetlag and Obesity. Current Biology, Volume 22, Issue 10, 939-943, 10 May 2012. doi: 10.1016/j.cub.2012.03.038

What is it about: A huge number of Europeans from various ages, latitudes and longitudes were assessed for a variety of circadian, sleep and health parameters. It turns out that most suffer from “social jet-lag” – an internal desynchronization between various body clocks as a result of continuous mismatch between the natural body rhythms and societally and culturally imposed wake-up, school, work and bed-time schedules. During the school/work week, people are massively sleep deprived. They then make up for it, “paying off the sleep debt”, over the weekends. The difference between the amount of sleep one gets on work/school nights and the amount of sleep one gets during the weekend is especially stunning in adolescents, whose internal clocks are naturally phase-delayed and thus most dramatically out of sync of what the society is forcing them to do:

roenneberg image

Average sleep time by age and gender (top) and discrepancy between workday and weekend sleep (bottom)

One of the most remarkable results is that people with the largest workday/weekend discrepancy, the most socially jet-lagged individuals, are also most prone to smoking, drinking, obesity and other health problems. Naturally thin people (B) did not get obese if they were more sleep deprived, but those somewhat prone to obesity became obese if they were also sleep deprived due to social jet-lag:

roenneberg image2

Effect of social jetlag on obesity in obesity-prone people (top) and thin people (bottom)

What is new: Bits and pieces of this were known for a while. But nobody has ever done such a tremendous study on such a large number of people, controlling for so many factors and measuring so many parameters and so many outcomes. This is definitely a tour-de-force paper of the year in this field and is appropriately matched with a brand new book by the lead author – Internal Time: Chronotypes, Social Jet Lag, and Why You’re So Tired – which I am currently reading.

Take-home message: Socially imposed school and work schedules are messing with our health. Political will is needed to change the mindset, change the culture, and change the way we use time in the society.

Some more thoughts: This paper goes together well with the several papers described above – living a life outside of synchrony with the light-dark cycle of the natural environment (and no, artificial indoor light cannot match it) has serious health consequences, leading to metabolic, physiological, reproductive and psychological problems that negatively affect billions of people on Earth, and cost the society billions of dollars of lost productivity, unnecessary medical care, and loss of educational potential in teenage students.

SUMMARY

Genes are, for the most part, invisible to natural (and sexual) selection.

What evolution can work on are phenotypes – composites of anatomical, physiological and behavioral traits as they change during the development and lifetime of an organism. Genes are selected for, indirectly, inasmuch as they contribute to the phenotype. While in different organisms and in different cases selection may act on a number of different levels – genes, embryos, cells, organs, organisms, groups, species – usually the most important unit of selection is the individual organism.

How a gene contributes to the phenotype is affected by many factors – multiples ways of splicing it, multiple ways of post-translational modification, which other genes are present, where and when is it expressed during development, interactions between cells, tissues and organs, and interactions between the organism and its environment. As genes, chromosomes and genomes sometimes get duplicated, this provides more opportunities for traits, previously resulting from higher-level interactions, to get incorporated into the genetic instructions via the process of genetic assimilation.

The basic unit of life is the cell. A single-celled organism has to have all of its internal processes coordinated in order to display adaptive responses to the environment in order to survive and reproduce. In multi-celled organisms, each cell type has to behave properly, communicate properly with the other cells, and coordinate its activities with all the other cells in the body for the organism to display adaptive responses to the environment in order to survive and reproduce.

Molecules that do all, or almost all of the work are proteins. They build structures, they catalyze reactions, break down food, store and use energy, control communication between cells, regulate the expression of the genes, and more.

But proteins are hard to study! Nucleic acids are much easier – they are stable, inert, the 3D conformation does not matter, and laboratory techniques have been developed to discover, sequence and study snippets of DNA and RNA in ways that today can be done by middle-schoolers or in DIY science projects. When you have the hammer, everything is a nail. When you have genetic tools, your graduate students are instructed to use them. And then sometimes they forget why they are doing this in the first place…

We study nucleic acids because they are markers, or proxies, for proteins. We locate genes and hope that the processes of transcription, splicing and translation do not confound too much what the resulting proteins are and what they do. This means that study of genes – their sequences and patterns of expression – is a reasonable first step in studying a biological phenomenon as it provides us with tools and information needed to study proteins, cells and higher-order phenomena that are evolutionarily relevant.

Of the Big Four – anatomy, biochemistry, physiology, behavior – it is behavioral traits that are the furthest removed from the underlying genes. It is really difficult to find genes directly involved in behavior. Big screens for genes for behaviors usually come up with genes for kinases, neurotransmitter receptors, neuronal development factors and other generalized components of the nervous system.

Circadian clock is an exception. While one may argue that the clock is not actually a behavior but a physiological mechanism that regulates many other behaviors, it is still the closest to a behavioral trait we ever got in discovering underlying genetics. Most people in the field agree that all major genes involved in clock function have been discovered (mostly during the 1990s) and that it is not productive to search for more.

Sure, the Abstract book of last week’s SRBR meeting still contains some posters and blitz-sessions by students with a detailed genetics work (well, the students need to learn the techniques, right?), but most of the Big Honchos of the field have moved on – to properties of the entire cells, neural networks, properties of multi-clock systems, and interactions with the environment. In a sense, after a detour of the 1990s when all the focus and energy was placed into gene discovery (“opening the black box”), the field of chronobiology is going back to its roots – a historically incredibly comparative and integrative subdiscipline of biology.

For a long time we have thought of circadian clocks as simply timers – something that determines when other downstream functions happen. But evidence over the last couple of decades has accumulated that clocks are much more intimately involved in some of those functions, beyond just timing.

Ten years ago, when I was exiting the field, the interaction between clocks and metabolism was just starting to be explored. We learned that fruitfly clock-gene timeless is involved in cocaine addiction. We learned that mutations in clock genes that change circadian period also change other aspects of timing, from frequencies of fruitfly courtship songs, to developmental timing in nematodes, to photoperiodic responses, to reproductive cycles.

Today, involvement of the circadian clock in many aspects of metabolism is probably the most exciting and most heavily studied area in the field. And this is shown by all the papers I highlighted today. The focus away from identification of genes and moving on to proteins, cells, neural networks, multi-oscillatory systems, and interactions with the environment are making the field as exciting as ever, and in vanguard of much of the rest of biology which is still overly focused on DNA. And the findings have obvious and stark implications not just for our better understanding of Life, but also for understanding of adaptation of organisms to the changing climate, and for understanding the consequences on human health.

The Scienceblogging Weekly (May 25th, 2012)

Blog of the Week:

Over the years, Better Posters blog has become the “Go To” place to send students when they start preparing posters for their first scientific meetings. Updated weekly, on Thursdays, this blog by Dr. Zen Faulkes (who also blogs at his other two awesome blogs NeuroDojo and Marmorkrebs, as well as on the #SciFund blog) provides ideas, suggestions, underlying theory, and thorough, fair critiques of poster design for scientific conferences. It is a link I (and I am sure many others) send whenever asked what is the best resource for preparing a good poster. Zen Faulkes also has a broader category of posts about presentations in general, both oral and poster, under the Zen of Presentations tag on his other blog.

Top 10:

Phineas Gage’s connectome by Mo Costandi:

Anyone who has studied psychology or neuroscience will be familiar with the incredible case of Phineas Gage, the railroad worker who had a metre-long iron rod propelled straight through his head at high speed in an explosion. Gage famously survived this horrific accident, but underwent dramatic personality changes afterwards. In recent years researchers reconstructed his skull and the passage of the rod through it, to try to understand how these changes were related to his brain damage. Now, neuroscientists from the University of California, Los Angeles have produced Gage’s connectome – a detailed wiring diagram of his brain, showing how its long-range connections were altered by the injury.

Replication studies: Bad copy by Ed Yong:

Positive results in psychology can behave like rumours: easy to release but hard to dispel. They dominate most journals, which strive to present new, exciting research. Meanwhile, attempts to replicate those studies, especially when the findings are negative, go unpublished, languishing in personal file drawers or circulating in conversations around the water cooler. “There are some experiments that everyone knows don’t replicate, but this knowledge doesn’t get into the literature,” says Wagenmakers. The publication barrier can be chilling, he adds. “I’ve seen students spending their entire PhD period trying to replicate a phenomenon, failing, and quitting academia because they had nothing to show for their time.” These problems occur throughout the sciences, but psychology has a number of deeply entrenched cultural norms that exacerbate them. It has become common practice, for example, to tweak experimental designs in ways that practically guarantee positive results. And once positive results are published, few researchers replicate the experiment exactly, instead carrying out ‘conceptual replications’ that test similar hypotheses using different methods. This practice, say critics, builds a house of cards on potentially shaky foundations…

Plan X; or, Planning White’s Small Step by Amy Shira Teitel:

In 1964, the launch schedule for the Gemini program was set and it was tight. Missions with new objectives would launch every eight to ten weeks taking NASA a step closer to the Moon each time. But hardware setbacks and some surprising feats by Soviet cosmonauts took a toll on the schedule. In the first half of 1965, NASA developed a plan that would see Gemini match and begin to overtake the Soviet Union in space. It was done largely in secret and known internally as Plan X….

Against the Infantilization of the Natural History Museum by Justin Erik Halldór Smith (and related: Relics With Much to Tell About Bird Diets May Be Lost to Time by Sarah Fecht):

…The project of exhaustively collecting and describing the basic kinds of large animal, and analyzing and displaying these animals’ bodily parts and systems, is a project that gained momentum in the late Renaissance and that was largely completed by the end of the 19th century. Like, say, realist painting in the Western tradition, it is a project that has a bounded history (indeed the two histories fairly closely overlap one another). This means that an alpaca intestine displayed in formaldehyde is a sample of a part of a South American camelid; but it is also an artefact of a modern European knowledge project. In this respect a proper natural history museum, that is to say an unreconstructed adult natural history museum, is really two museums at once: it is a museum of nature, but also a museum of the history of a very singular attempt to know nature quite literally inside-out….

What a Physics Student Can Teach Us About How Visitors Walk Through a Museum by Henry Adams:

….To devise a good layout requires some understanding of what museum visitors do, and there’s surprisingly little literature on this topic. Most of the studies of museum-goers that I’ve seen rely on questionnaires. They ask people what they did, what they learned, and what they liked and didn’t like. No doubt there are virtues to this technique, but it assumes that people are aware of what they’re doing. It doesn’t take into account how much looking depends on parts of the brain that are largely instinctive and intuitive and often not easily accessible to our rational consciousness. Was there another mode of investigation and description that would illuminate what was actually taking place?…

Lies You’ve Been Told About the Pacific Garbage Patch by Annalee Newitz:

You’ve probably heard of the “Pacific garbage patch,” also called the “trash vortex.” It’s a region of the North Pacific ocean where the northern jet stream and the southern trade winds, moving opposite directions, create a vast, gently circling region of water called the North Pacific Gyre — and at its center, there are tons of plastic garbage. You may even have seen this picture of the garbage patch, above — right? Wrong….

The (misunderstood) language of DNA by Genegeek:

I love analogies and use them often to get people to think about scientific concepts in new ways. I’ll share some of my favourite ones on the blog but today, I want to talk about Analogies Gone Bad….There is a lovely analogy to help people understand DNA code: DNA can be seen as a language…

Killers that sux by DrRubidium:

You might notice the sting of the injection. Within seconds you’d realize you’re having trouble moving your eyes and fingers, followed by your arms and legs. If you were standing, you’d collapse. In a heap on the floor, you’d realize nearly every muscle in your body was paralyzed. Being fully conscious, your sense of panic would be rising as rapidly as the paralysis was spreading. Swallowing and breathing has become more and more difficult. Slipping into unconsciousness, your last conscious thought may well be “I am going to die.”…

What Is the “Bible of Psychiatry” Supposed to Do? The Peculiar Challenges of an Uncertain Science by Vaughan Bell:

The American Psychiatric Association have just published the latest update of the draft DSM-5 psychiatric diagnosis manual, which is due to be completed in 2013. The changes have provoked much comment, criticism, and heated debate, and many have used the opportunity to attack psychiatric diagnosis and the perceived failure to find “biological tests” to replace descriptions of mental phenomena. But to understand the strengths and weaknesses of psychiatric diagnosis, it’s important to know where the challenges lie….

Do Plants Smell Other Plants? This One Does, Then Strangles What It Smells by Robert Krulwich:

“Plants smell,” says botanist David Chamovitz. Yes, they give off odors, but that’s not what Chamovitz means. He means plants can smell other plants. “Plants know when their fruit is ripe, when their [plant] neighbor has been cut by a gardener’s shears, or when their neighbor is being eaten by a ravenous bug; they smell it,” he writes in his new book, What a Plant Knows. They don’t have noses or a nervous system, but they still have an olfactory sense, and they can differentiate. He says there’s a vine that can smell the difference between a tomato and a stalk of wheat. It will choose one over the other, based on…smell! In a moment I’ll show you how….

Chossat’s Effect in humans and other animals

This post was originally published on April 09, 2006.

This April 09, 2006 post places another paper from my old lab (Reference #17) within a broader context of physiology, behavior, ecology and evolution. The paper was a result of a “communal” experiment in the lab, i.e., it was not included in anyone’s Thesis. My advisor designed it and started the experiment with the first couple of birds. When I joined the lab, I did the experiment in an additional number of animals. When Chris Steele joined the lab, he took over the project and did the rest of the lab work, including bringing in the idea for an additional experiment that was included, and some of the analysis. We all talked about it in our lab meetings for a long time. In the end, the boss did most of the analysis and all of the writing, so the order of authors faithfully reflects the relative contributions to the work.

What is not mentioned in the post below is an additional observation – that return of the food after the fasting period induced a phase-shift of the circadian system, so we also generated a Phase-Response Curve, suggesting that food-entrainable pacemaker in quail is, unlike in mammals, not separate from the light-entrainable system.

Finally, at the end of the post, I show some unpublished data – a rare event in science blogging.

If you know what Chossat’s Effect is, I guess you are a) a physiologist, b) expert in thermoregulation, and c) old. This is term that got expunged from the scientific lexicon a few decades ago, in an effort – correct me if I am wrong on this – spearheaded by the U.S. textbook companies, to replace scientific terminology named after the discoverers (and sometimes even Latin and Greek terms) with bland English neologisms.

But I love Schwann’s Cells, Fallopian Tubes (or Mullerian Ducts), Purkinje Fibers, Brocca’s Area and the amazing Bundle of His! Those terms are memorable, make it easy to sneak in some historical context into teaching science, and have an emotional effect of bringing forth images of ancient scientists working under candlelight, sacrificing their eyesight and health, their social standing and sometimes even their lives, in the feverish hunger for knowledge.

So, what is Chossat’s Effect? It comes from a 19th century French scientist who was studying the physiology of starvation [1]. The ‘modern’ term for this effect is “fasting-induced nocturnal hypothermia” (doesn’t that sound like something that would prompt the students in the classroom to immediatelly stop paying attention to the teacher and instead pick-up their cell-phones and start text-messaging their friends?).

Actually, this is a very interesting area of research that is very tightly connected to circadian biology. This post is likely to be long, so feel free to skim and just focus on the first part if you are into birds, second part if you are interested in mammals, and the last part if you are into humans.

Birds

All warm-blooded animals (and yes, that includes at least some reptiles, not to mention a few heat-producing plants like stink-cabbage) exhibit a daily rhythm of body temperature. If an animal is active during the day (diurnal) and sleeps during the night, reducing the metabolic rate during the night is a good way to save energy.

Some of the smallest birds, like swifts and hummingbirds, need to feed continuously in order to stay alive. At night, when they are not able to forage (flowers are closed, it’s hard to see, and owls are hunting at the time), they drop their metabolic rate, and thus body temperature, quite dramatically. The body temperature gets down as low as the environmental temperature, sometimes daringly close to the freezing point. The total drop can be as large as 40 degrees Celsius in some instances! This is called daily torpor (yup, click on that link – it is an excellent blog post) and the metabolic rate drops as much as 95% [2, 3]. This is like full-scale winter hibernation EVERY DAY!

Chossat’s effect does not refer to daily torpor, though. It describes a drop in temperature during the night that is larger than the usual circadian fluctuation, in animals undergoing fasting, e.g., during spells of very bad weather (e.g., hurricanes).

Normal amplitude (daily maximum minus nightly minimum) of body temperature in birds with normal access to food ranges between about 1 and 2 degrees Celsius. For instance, a daily maximum may be 41 degrees and the nightly minimum may be 39 degrees (yes, the birds are much warmer than mammals, which makes them inhospitable to microbes that cause many mammalian diseases), which calculates to 2 degrees of amplitude.

During fasting (or food deprivation in the laboratory), the nightly minima drop down to lower levels than in fed birds. The minimum gets lower and lower with each additional night. Importantly, the daily maxima do not change at all. It is thought that it is advantageous for birds to retain their normal metabolic rates during the day so they can immediately resume foraging once the bad weather subsides. Also, if the bad weather persists for too long, the birds need the daytime metabolic rates in order to fly away [4].

According to John Wingfield’s “Emergency Life-History Stage” hypothesis [5], an individual’s perception of inclement weather directly affect the levels of stress hormones (e.g., corticosterone). An individual who does not perceive the bad weather to be “too bad”, will reduce daytime activity and reduce night-time temperature in order to save energy – this individual has made a decision to sit it out.

On the other hand, an individual who perceives bad weather to be “really bad” (or if it lasts too long) will have higher levels of stress hormones and will attempt to fly away during the day. This is not the same mechanism as the seasonal migration, which is usually a nocturnal flight, i.e., they do not experience Zugunruhe, just stress. Stressed birds do not attempt to escape at night, at which time they have allowed their body temperature to drop by several degrees.

Nocturnal hypothermia has been studied in a large number of species of birds (see, for examples, references # 6-12), but most of the work was performed on pigeons [13-15] and quail [16]. Not all avian species exhibit this response. Laurilla at al. [18] write:

“On the other hand, many large birds that are adapted to long fasting periods as a part of their life histories, e.g. penguins and geese (Cherel et al., 1988; Castellini andRea, 1992), owls (Hohtola et al., 1994) and some raptors (McKechnie andLovegrove, 1999) do not show marked hypothermia during fasting. Some species enter hypothermia upon food restriction only when isolated from conspecifics in a laboratory environment, while in the field they remain normothermic by huddling. These observations have even led some authors to question the usefulness of the concept of hypothermia (Lovegrove and Smith, 2003).”[8]

Here is a graphic example of a fasting-induced nocturnal hypothermia in quail (from[17]). The period between the two triangles is the time (3 days) during which the birds had water but no food. Before and after, birds were fed ad libitum. Below is a graph that shows the difference between the temperature minima during the first, second and third day (top) and night (bottom) of food deprivation in comparison to the last three days and nights of normal feeding prior to the fasting treatment:


Much of the more recent research is looking at other environmental cues that can modify the Chossat’s effect, as well as the involvement of the circadian clock in this time-specific form of thermoreguluation.

For instance, some of the ambient cues that affect the response include ambient temperature [16, 20], ambient light [17], photoperiod [18, 19], single vs. repeated fasting [18, 19], caloric food restriction vs. complete food deprivation [13], social situation, e.g., opportunity for huddling [8] and presence of stationary vs. flying predators [19, 20]. Here is an example of an effect of ambient temperature on nocturnal hypothermia in fasted pigeons (from [20]). Lower the ambient temperature, deepeer the Chossat’s effect:

Here is the effect of the presence of a predator (from [2]). In the presence of a perched hawk (P), nocturnal hypothermia reached normally low levels. In the presence of the flying hawk (F), temperature did not drop as much. Presumably, the pigeons kept the metabolic rate high enough to be able to fly fast if needed:

As stated above, hypothermia occurs only during the night while the temperature during the days remains normal. However, all the studies are performed either in natural conditions of day and night or in light-dark cycles in the laboratory. In constant darkness, the circadian rhythm of temperature persists and hypothermia is apparent. Moreover, the temperature drops both at the minima during the ‘subjective night’ and at the maxima during the ‘subjective day’ (from [17]):


This suggests that light has a direct (or “masking“) effect on body temperature during the light-phase of the cycle. But is this effect acting directly on the thermoregulatory centers in the hypothalamus or is it mediated by the circadian clock that drives the rhythm of body temperature? In Japanese quail, the circadian pacemakers are located in the eyes. When the eyes are removed [17], both the daily maxima in the light-phase and the nightly minima during the dark phase drop, suggesting that the effect is mediated via the circadian clock, as the light perceived by the photoreceptors in the pineal gland and in the deep brain is incapable of keeping the daily maxima from dropping:


Mammals

Some small mammals, such as smallest rodents and shrews, exhibit a full-blown daily torpor either normally [21] or in response to fasting [22]. Here is an example of a daily torpor of a mouse-opposum:

In nocturnal animals, which many mammals are, body temperature is high at night when the animals are active and it drops during the day when the animals are sleeping. In rats, fasting induces diurnal hypothermia, i.e., drop of the daily minimum during the day (black circles, compared to pre- and post- treatment values in white symbols) while the nightly maxima remain unaffected [23]:

Chronic caloric food restriction leads to the drop in both the daily minima and nightly maxima of temperature [24]. All the studies until recently have studied responses in relatively small animals (both birds and mammals) with high metabolic rates and high energy needs.

But do larger animals, like humans, also exhibit Chossat’s effect? After all, the first documented case, that by Chossat himself, was in a dog. This was repeated recently [25]. But even dogs are pretty small compared to humans.

Recently, researchers have addressed this question in a number of species of large mammals, including sheep, goats, horses and yaks [26-29]. Some additional environmental cues were also studied, including the effects of shearing on the circadian temperature rhythm in sheep [30]. Here is a record from a goat:

Notice that, unlike in birds, both the maxima and minima gradually go down.

But, as far as I could find by digging through the literature, nobody has ever performed a similar study in humans. I am assuming that it has been noticed if body temperature drops in fasted humans, but I am not aware of a study systematically addressing this question.

Humans

More than a decade ago I was teaching one of many sections of an Animal Anatomy and Physiology Course. This course requires students to perform a research project. One group of students studied the effects of fasting on body temperature and blood pressure in humans.

They found 8 subjects, all healthy, athletic, non-drinking, non-smoking students ages 19-23. They were instructed to eat normally during the Day1 of the experiment. They subsequently spent 36 hours in a house drinking only water and eating nothing. Every four hours, temperature and pressure were measured. By using kids’ digital ear thermometers and manual sphigmomanometers they managed, for the most part, not to awaken the subjects during the night. Here are examples of body temperature of three of the subjects – Night1, followed by Day2 and Night 2:



Here are the pooled data for all eight subjects, starting with Day2 and followed by Night1 and Night2 plotted on top of each other for comparison:

Obviously, body temperature of Night2, after a day of fasting, was lower than that of Night1, after the day of normal feeding. I do not have their raw data any more, but if I remember correctly, the data for blood pressure looked very similar. I heard they had a huge breakfast, courtesy of the young researchers, at the end of the experiment.

So, Chossat’s Effect appears to be operating in humans as well. Now, this is cool in itself, and I sure hope that someone with access to good clinical lab repeats this study, but there is something else about these data that really excites me. This finding can be used as a tool for studying something entirely different!

The Hypothesis

One of the first demonstrations that humans have daily rhythms involved the time-of-day dependence of time perception. In other words, our subjective “feel” of the speed of passage of time changes systematically with the time of day. At the same time, it has been known for a couple of centuries now that the subjective time perception is also altered during fever. And we know that circadian clock governs daily rhtyhms of body temperature.

So, what affects the time perception: time of day or body temperature? If the time passes faster in the evening than at dawn, is it because of the circadian clock acting on the time-perception brain-centers directly, or because we are warmer at the time (which is also driven by the circadian clock)?

This question has haunted circadian researchers for decades and they have devised ever more elaborate experiments to tease the two hypotheses apart, with no avail – we still do not know. But, if by depriving the subjects of food, we can dissociate clock-time from temperature, perhaps we can address this question after all. If the subjective perception of 1 minute (do not use 1 second or 1 hour – those are durations unsuited for this experiment) is similar between the night after a fed day and the night after the fasting day, then the perception is directly driven by the circadian clock.

If, on the other hand, perception of a minute changes systematically between the two nights, then we conclude that it is body temperature that affects subjective time perception. Please, someone do this! And if you do, or even if you just want to replicate the Chossat’s Effect in humans, I would appreciate it if you would properly cite this post:

When Should Schools Start in the morning?

==========

I am glad to see that there is more and more interest in and awareness of sleep research. Just watch Sanjay Gupta on CNN or listen to the recent segment on Weekend America on NPR.

At the same time, I am often alarmed at the levels of ignorance still rampant in the general population, and even more the negative social connotations of sleep as an indicator of laziness.

Nothing pains me more than when I see educators (in comments) revealing such biases in regards to their student in the adolescent years. Why do teachers think that their charges are lazy, irresponsible bums, and persist in such belief even when confronted with clear scientific data demonstrating that sleep phase in adolescents is markedly delayed in comparison to younger and older people?

In short, presumably under the influence of the sudden surge of sex steroid hormones (and my own research gently touched on this), the circadian clock phase-advances in teen years. It persists in this state until one is almost 30 years old. After that, it settles into its adult pattern. Of course, we are talking about human populations, not individuals – you can surely give me an anecdote about someone who does not follow this pattern. That’s fine. Of course there are exceptions, as there is vast genetic (and thus phenotypic) variation in human populations. This does not in any way diminish the findings of population studies.

Everyone, from little children, through teens and young adults to elderly, belongs to one of the ‘chronotypes’. You can be a more or less extreme lark (phase-advanced, tend to wake up and fall asleep early), a more or less extreme owl (phase-delayed, tend to wake up and fall asleep late). You can be something in between – some kind of “median” (I don’t want to call this normal, because the whole spectrum is normal) chronotype.

Along a different continuum, one can be very rigid (usually the extreme larks find it really difficult to adjust to work schedules that do not fit their clocks), or quite flexible (people who find it easy to work night-shifts or rotating shifts and tend to remain in such jobs long after their colleagues with less flexible clocks have quit).

No matter where you are on these continua, once you hit puberty your clock will phase-delay. If you were an owl to begin with, you will become a more extreme owl for about a dozen years. If you are an extreme lark, you’ll be a less extreme lark. In the late 20s, your clock will gradually go back to your baseline chronotype and retain it for the rest of your life.

The important thing to remember is that chronotypes are not social constructs (although work-hours and school-hours are). No amount of bribing or threatening can make an adolescent fall asleep early. Don’t blame video games or TV. Even if you take all of these away (and you should that late at night, and replace them with books) and switch off the lights, the poor teen will toss and turn and not fall asleep until midnight or later, thus getting only about 4-6 hours of sleep until it is time to get up and go to school again.

More and more school districts around the country, especially in more enlightened and progressive areas, are heeding the science and making a rational decision to follow the science and adjust the school-start times accordingly. Instead of forcing teenagers to wake up at their biological midnight (circa 6am) to go to school, where invariably they sleep through the first two morning classes, more and more schools are adopting the reverse busing schedule: elementary schools first (around 7:50am), middle schools next (around 8:20am) and high schools last (around 8:50am). I hope all schools around the country eventually adopt this schedule and quit torturing the teens and then blaming the teens for sleeping in class and making bad grades.

No matter how much you may wish to think that everything in human behavior originates in culture, biology will trump you every now and then, and then you should better pay attention, especially if the life, health, happiness and educational quality of other people depends on your decisions.

======

Recently, Lance Mannion wrote an interesting post on the topic, which reminded me also of an older post by Ezra Klein in which the commenters voiced all the usual arguments heard in this debate.

There are a couple of more details that I have not touched upon in the previous posts.

First, lack of sleep can lead to obesity and even diabetes, as the circadian clock is tightly connected to the ghrelin/leptin system of hormonal control of hunger, feeding and fat-deposition.

Second, lack of sleep discourages exercise. Put these two pieces of data together, and you get a national epidemic of obesity, not just a bunch of sleep-deprived children.

Third, lack of sleep has a well-documented effect on mood. No, teenagers are not naturally that moody – at least not all of them. They are just barely “functional” (instead of “optimal”) and walk through life like zombies because they are operating on 4-8 hours of sleep instead of 9 hours (optimal for teens, it goes down to about 8 for adults). Of course they are moody.

Fourth, chronic sleep deprivation can have long-term consequences, ranging from psychiatric diseases to cancer. Remember that teens in high-school (and college students are faring worse!) are constantly jet-lagged!

There is even a hypothesis floating around that sleep-delay in adolescence may affect the onset of picking up smoking.

Fifth – and I did not think of this although it is obvious – teenagers above a certain age, still in high school, are allowed to drive. If they are driving themselves to school at 6 or 7am, when their circadian clocks think is it 3 or 4am, it is as if they are driving drunk. There is actually a scale devised by one of the sleep researchers that tells which time of the night corresponds to what number of bottles of beer. Driving at 4am (or driving a ship, like Exxon Valdez, or operating a power-plant, like one in Chernobyl) is the equivalent of driving drunk – way over the legal limits. Teenagers driving at 7am are equally “drunk”.

One of the reasons for the resistance to healthy initiatives to change school-start schedules stems from the fact that the world is organized by adults and adults want to have the world run according to schedules that fit their moods and are unwilling to change it – they may not know that teens feel differently, or they defend their preferences nonetheless.

A large proportion of adults in this country still subscribe to barbaric notions that sleep is a shameful activity, a sign of laziness, and that teens need to be tortured in order to “steel” them to grow into “real men”. This has roots all the way back to the Puritan so-called “work-ethic” which is really a “no fun for anyone” punitive ethic long ago shown to be physically and emotionally debilitating.

When I was a kid, back in old now-non-existent Yugoslavia, most schools in big urban areas worked in two shifts. All the kids started school at 8am and ended at 1:15pm for one week, then started at 2pm and ended at 7:15pm the next week, and so on…

If a school had, let’s say, twelve classes of the seventh grade, six of those would be in the A-shift and the other six in the B-shift. Each shift had its own complete set of teachers, assistants, nurses…everything except the one shared Principal and the school psychologist.

The time between 1:15pm and 2pm was for supplementary classes (either for those who needed extra help, or for those preparing for Math Olympics and such) and clubs. That was also time for kids from two shifts to meet and get to know each other (it is amazing how many kids from opposite shifts started dating each other after the year-end Big Trip to the Coast). There was no such thing as the American hype for high-school competitive sports, which I still find strange and curious after 15 [now 20] years in this country.

Thus, you get to sleep in for a week (but miss out on afternoon activities), then have to get up relatively early for a week but have the afternoon free to gallivant around town. Nobody there understands what’s the American fuss over kids being home alone – of course they are home alone, cleaning the house, fixing meals, doing homework and BETTER be getting to school on time!

Teachers were pretty understanding about sleeping types. I do not recall ever having a big test, quiz or exam being given at the extremes of the day (around 8am or around 7pm). As an owl myself, I was much more likely to raise my hand, participate in discussions, or volunteer for oral examinations during the week when I was in school in the afternoon, and that was fine with most of my teachers.

Transportation was not an issue. Most kids lived close enough to their neighborhood school to walk. For those who lived a little farther away – hey, no problem, that’s Europe, so Belgrade has a huge and pretty efficient public transportation system. I do not remember ever seeing any of my friends ever being dropped off to school by a parent driving a car! Or being brought to or picked up from school by a parent beyond fourth grade at all – period. And the minimum driving age being 18, nobody drove themselves to school either.

In rural areas, there was no need for two shifts – something like 9am-2:15pm was good enough to accommodate all of the kids.

I do not think that this kind of system can be implemented in the USA. It relies on an efficient public transportation which, with exception of a few oldest East Coast cities, is practically non-existent. American cities have been built for cars.

But some things can be done.

First, swap the starting times so elementary kids go to school first, middle school next and high school last (e.g., around 8am, 8:30am and 9am respectively). Studies show that teens do not go to sleep later if their school starts later. Some cynics claim that is what teens will do. But they do not. Actually, they fall asleep at the same time, thus gaining an additional hour of sleep.

Teens are almost adults. The current generation of teens, perhaps because of a closer and tighter contact with their parents than any generation before, is the most serious, mature and responsible generation I have seen. Give them a benefit of the doubt. Just because you were into mischief and hated your parents when you were their age does not mean that today’s kids are the same.

Second, start the school day – for all kids every day – with PE (or some kind of exercise), preferably outdoors, as both exposure to daylight and the exercise have been shown to aid in phase-shifting the circadian clock.

Third, let them eat breakfast afterwards (sticking to a meal schedule also helps entrain the clock). Follow up with the electives which kids may be most interested in.

By the time they hit math, science and English classes around 11 or so, their bodies are finally fully awake and they can understand what the teacher is saying, and do the tests with a clear mind instead of in a sleepy haze.

Do not permit any caffeine to be sold in schools. Advise parents not to allow TV or any other electronics to be in kids’ bedrooms. Let them enjoy those activities in the living room. Bedroom is for sleeping, and sleeping alone. A book before bed is fine, but screens just keep them awake even longer.

Finally, rethink all those extra activities you are forcing the teens to do: sports, art, music, etc. In teen’s minds, the day does not start with the beginning of school in the morning. We may think that we are at work most of our day. Teens do not – they consider their day to begin at the time school-day is over. Their day begins in the afternoon. School is something they have to deal with before they can have their day. Realize this and give them time and space to do with their day what they want. Do not push them to do things that you think they’ll need to get into Harvard. Let them be – leave them alone. Then they’ll go to sleep at a normal time.

Concern for our kids’ physical and mental health HAS to trump all other concerns, including economic costs, cultural traditions and adult preferences. We have a problem and we need to do something, informed by science, to fix the problem. Blaming the messenger, proposing to do nothing, and, the worst, blaming the kids, is unacceptable.

===============

All of this targets high-schoolers. However, there is barely any mention of college students who are, chronobiologically, in the same age-group as high-school students, i.e., their sleep cycles are phase-delayed compared to both little kids and to adults.

In a way, this may be because there is not much adults can do about college students. They are supposedly adults themselves and capable of taking care of themselves. Nobody forces (at least in theory) them to take 8am classes. Nobody forces them to spend nights partying either.

They are on their own, away from their parents’ direct supervision, so nobody can tell them to remove TVs and electronic games out of their bedrooms. The college administrators cannot deal with this because it is an invasion of students’ privacy.

Forward-looking school systems in reality-based communities around the country have, over the last several years, implemented a policy that is based on science – sending elementary school kids to school first in the morning, middle-schoolers next, and high-schoolers last. This is based on the effects of puberty on the performance of the human circadian clock.

For teenagers, 6am is practically midnight – their bodies have barely begun to sleep. Although there have been some irrational (or on-the-surface-economics-based) voices of opposition – based on outdated notions of laziness – they were not reasonable enough, especially not in comparison to the scientific and medical information at hand, for school boards to reject these changes.

I am very happy that my kids are going to school in such an enlightened environment, and I am also happy to note that every year more school systems adopt the reasonable starting schedules based on current scientific knowledge.

Yet, college students are, from what I heard, in much worse shape than high-schoolers. Both groups should sleep around 9 hours per day (adults over thirty are good with about 8 hours). High-schoolers get on average 6.9 hours. College students are down to about five! The continuous insomnia of college students even has its own name in chronobiology: Student Lag (like jet-lag without travelling to cool places). Is there anything we, as a society, can do to alleviate student lag? Should we?

===============

This kind of ignorant bleating makes me froth at the mouth every time – I guess it is because this is my own blogging “turf”.

One of the recurring themes of my blog is the disdain I have for people who equate sleep with laziness out of their Puritan core of understanding of the world, their “work ethic” which is a smokescreen for power-play, their vicious disrespect for everyone who is not like them, and the nasty feeling of superiority they have towards the teenagers just because they are older, bigger, stronger and more powerful than the kids. Not to forget the idiotic notions that kids need to be “hardened”, or that, just because they managed to survive some hardships when they were teens, all the future generations have to be sentenced to the same types of hardships, just to make it even. This is bullying behavior, and disregarding and/or twisting science in the search for personal triumphalism irks me to no end.

I hated getting up early, too. I still hate it, and I’m so far beyond growth hormones that I don’t even remember how they felt. But I do remember that in middle and high school, I dragged myself out of the house at 5 a.m. every day of the week to deliver papers before I caught the 6:45 a.m. bus to school. I never fell asleep in class. Neither did anybody else. And something caused me to grow 6 inches and add 35 pounds between sophomore and junior year. At the end of that kind of day, complete with cross-country, basketball or track, I had no trouble falling asleep at 10 p.m.

He said that he grew up in height and weight when he was in high school. Who knows how much more he would have grown if he was not so sleep deprived (if his self-congatulatory stories are to be believed and he did not slack off every chance he had). Perhaps he would not grow up to be so grouchy and mean-spirited if he had a more normal adolescence.

I don’t know where he got the idea that growth hormone is a cause of the phase-delay of circadian rhythms in adolescence. It could be, but it is unlikely – we just don’t know yet. But, if a hormone is a cause, than it is much more likely to be sex steroids. Perhaps his sleep-deprived and testosterone-deprived youth turned him into a sissy with male anxiety he channels into lashing at those weaker than him?

In previous centuries, adolescents in an agrarian society got up at 4:30 or 5a.m. with their parents to milk the cows or do any other of a long list of chores. Did growth hormones pass them by? Where were the “studies” that showed they really needed to go to bed after midnight and sleep until 10? And why weren’t their parents all being reported to the DSS? Oh, that’s right, there was no DSS. How did that generation survive?

He assumes that in times before electricity, teenagers used to wake up and fall asleep at the same time adults did. Well, they did not. Studies of sleep patterns in primitive tribes show that adolescents are the last ones to wake up (and nobody bashes them for it – it is the New Primitives with access to the media that do that) and the last ones to fall asleep – they serve as first-shift sentries during the night watch.

Even in this, the 21st century, kids who enter the military at 17 find that they can fall asleep easily at 9:30 or 10, because they know they’re going to be getting up at 4:30 or 5. Apparently the Army hasn’t read the study on circadian rhythms.

Actually, the military being the most worried by this problem is funding a lot of research on circadian rhythms and sleep and has been for decades. Because they know, first hand, how big a problem it is and that yelling sargeants do not alert soldiers make.

Kids, if you need more sleep, my study shows there’s a simple way to get it. Turn off – I mean “power down” – the cell phone, the iPod and the computer sometime before 11 p.m. Turn off the TV. Turn off the light. Lie down in bed and close your eyes.

…and sit in the dark for the next four hours, heh?

What especially drives me crazy is that so many teachers, people who work with adolescents every day, succumb to this indulgence in personal power over the children. It is easier to get into a self-righteous ‘high’ than to study the science and do something about the problem. It is easier to blame the kids than to admit personal impotence and try to do something about it by studying the issue.

===============

My regular readers are probably aware that the topic of adolescent sleep and the issue of starting times of schools are some of my favourite subjects for a variety of reasons: I am a chronobiologist, I am an extreme “owl” (hence the name of this blog), I am a parent of developing extreme “owls”, I have a particular distaste for Puritanical equation of sleep with laziness which always raises its ugly head in discussions of adolescent sleep, and much of my own past research was somewhat related to this topic.

So, I was particularly pleased when Jessica of the excellent Bee Policy blog informed me of the recent publication of a book devoted entirely to this topic. Snooze…or Lose! by Helen Emsellem was published by National Academies and Jessica managed to get me an advanced reading copy to review.

You can also read the book online (or buy the PDF). Much more information on the topic can be found on the book webpage, on the National Slep Foundation website, on Dr.Emsellem’s homepage and the Start Later for Excellence in Education Proposal (S.L.E.E.P.) website. I strongly encourage you to look around those webpages.

Her daughter Elyssa wrote one of the chapters in the book and is promoting the book and the information relevant to teenagers at the place where teenagers are most likely to see it – on MySpace (you see – it’s not just music bands who caught onto this trick – serious information can be promoted at MySpace as well).

The main audience for this book are teenagers themselves and their parents – I think in this order although officially the order is reversed. Secondarily, the audience are teachers, administrators and officials in charge of school policy. Who this book is not targeted to are scientists and book reviewers because there are no end notes!

Anyway, considering that the main audience are teens, their parents and teachers (i.e., laypeople), the book is admirably clear and readable. The book starts out with presenting the problem – the chronic sleep deprivation of adolescents in modern society – and provides ample evidence that this is indeed a wide-spread problem. It continues with a simple primer on physiology of sleep and circadian rhythms, followed by a review of the current knowledge of the negative consequences of chronic sleep deprivation: from susceptibility to diseases, through psychological and behavioral problems, to problems of physical and mental performance.

A whole chapter – the one I found most interesting – is devoted to the role of sleep in various kinds of memory and the negative effects of sleep deprivation on learning – both declarative and episodic memory, as well as kinesthetic memory needed for athletic performance and safe driving. This is where I missed the end notes the most.

Throughout the book, Dr.Emsellem makes statements of fact about sleep that are obviously derived from research. I’d like to see the references to that research so I can evaluate for myself how strong each such statement is. Although my specialty is chronobiology (physiology, development, reproduction, behavior, ecology and evolution) of birds, and secondarily that of mammals, reptiles, invertebrates and microorganisms (I could never quite get excited about clocks in fish, fungi and plants, or molecular aspects of circadian rhythms, or medical aspects of human rhythms), I am quite familiar with the literature on sleep, including in humans.

Thus, I know that the statements in the book reflect scientific consensus but that the meaning of “consensus” is quite elastic. In some cases, it means “there is a mountain of evidence for this statement and no evidence against it, so it is highly unlikely that this will change any time soon”. In other cases it means “there are a few studies suggesting this, but they are not perfect and there are some studies with differing results, and this can stand for now but is likely to me modified or completely overturned by future research”.

Having end notes would help the expert reader see how weak or strong each one of these findings is, and would also be suggestive to lay readers that the statements in the book are supported by actual research and are not just the author’s invention as seen in so many self-help books. End notes and references add to the believability of the text even if one does not bother to check the papers out.

The book then turns to variety of factors, both biological and social, that conspire to deprive our teens of sleep, both from the perspective of a sleep researcher and from the perspective of teenagers. Little snippets of teenagers’ thoughts on the topic are included throughout the book and add an important perspective as well as make the book more fun to read. Otherwise, the “case studies”, the bane of so many psychology books, are kept to the minimum, discussed very briefly, and used wisely..

In the next section, Dr.Emsellem turns to solutions. First, she present several tests of sleep deprivation that readers can administer themselves in order to self-diagnose the problem. She then describes ten different strategies that parents and teens can work on together in order to solve the problem of sleep deprivation and all the concomittant negative effects (and Alyssa adds her own chapter on the teen perspective on how those can work). If that does not work, she describes additional methods that a sleep doctor may prescribe to help solve the problem. There is also a short chapter describing a couple of other sleep disorders, e.g., sleep apnea, that also contribute to sleep deprivation in affected individuals.

The last portion of the book addresses the social aspects of sleep deprivation and changes that parents and teens can make in their homes, as well as broader community, towards solving the problem. For adults, being a role model for the child is important and this requires paying attention to one’s own sleep hygiene.

The very last portion is really the raison d’etre of the book – how to make one’s community change the school starting times. The author presents a couple of examples of school districts in which such change was enacted, the strategies parents used to force such changes and the incredible positive results of such changes. The whole book is really designed to provide information to parents and teens who are working on changing their local attitudes toward school starting times.

The schools used to start about 9am for most of the century (and before). Then, due to the pressure from business and economic (read “busing”) woes of school districts, the school starting times started creeping earlier and earlier starting back in 1970s until they reach the horribly early times seen today in many places, requiring kids to get up as early as 5am in order to catch the school bus on time. As a result, high schoolers (and to some extent middle schoolers and college students) sleep through the first two periods in school, feel weak and groggy all day long, more easily succumb to diseases, have trouble learning and performing well in school and the athletic field, and are in too bad mood to be pleasant at home – this is not the natural state of things as much as the stereotype of the “grouchy teen” is prevalent in the society, it is mainly due to sleep deprivation and the biggest factor causing sleep deprivation are early school starting times.

In places in which enlightened and progressive school boards succumbed to the wishes of parents and students, i.e., in places in which parents and students used smart diplomatic tactics to engender such change, the positive results are astounding. The grades went up. The test scores went up. The students are happy. The parents are happy. The teachers are happy. The coaches are happy because their teams are winning all the state championships. There is a decrease in tardiness and absences. There is a decrease in sick days and even in numbers of diagnoses of ADD and depression in teens. There is a drop in teen crime. There is a drop in car accidents involving teens (by 15% in one place!). The whole county feels upbeat about it!

While the book makes me – a scientist – thirsty for end notes and references, it does remarkably well what it was designed to do – arm the parent and kids with knowledge needed to make a positive change in their communities – a change that is necessary in order to raise new generations to be healthy and successful, something we owe to our children.

We should do this no matter how much it costs, but the experiences from places in which the changes were made, contrary to doomsayers, is that there was no additional cost to this at all. The changes were implemented slowly and with everyone involved pitching in their opinion and their expertise until the best possible system was arrived at, adapted to the local community situation. No new buses were needed to be rented. No unexpected new costs appeared. And having a safe, happy community saved money elsewhere (e.g., accidents and crime rate decline). And it worked wonderfully everywhere.

So, get the book and let your child read it, you read it, give a copy to other people in your community: the teachers, the school principal, the pediatrician, the child psychologist, the school board members, the superintendent of education and the governor. This is something that is easy to do, there are no good reasons against it and the health and the future of our kids is at stake. It is something worth fighting for and this book is your first weapon.

(Non) Adaptive Function of Sleep

(Non) Adaptive Function of Sleep

This was first published on November 01, 2005.

Here is a nice article in Washington Post – Ecological Niche May Dictate Sleep Habits – about the adaptive function of sleep.

It addresses some of the themes I am interested in.

First, the unfortunate fact is that sleep was initially defined by researchers of humans, i.e., medical researchers. Inevitably, the (electrophysiological) definition of sleep was thus saddled with unnecessary anthropocentric elements that for decades hampered the study of evolution of sleep.

I was present at the meeting (here in Biotechnology Center in RTP) several years ago when the bigwigs of the sleep research community were first exposed to some very new ideas via not one but two talks about sleep in fruitflies (by Marcia Belvin and Joan Hendricks). That was quite an earthshaking event as the definition of sleep was substantially changed right then and there. Interestingly, the new (behavioral) definition was received not with resistance but with enthusiasm. Everyone in the room understood the potential of the new way of thinking to break off the shackles that sleep research had to suffer in for so long.

Since then, the marriage of circadian and sleep research has resulted in sleep research taking off at a breathtaking speed. As a result, many old assumptions and dogmas had to be discarded. For many years sleep researchers shunned evolutionary explanations and focused on physiological and medical aspects of the phenomenon. However, progress in sleep medicine depends on a better understanding of what sleep is for – a decidedly evolutionary question.

Another theme is the old battle between adaptationism and the more sophisticated view of evolution that incorporates the phenomena of developmental and phylogenetic constraints, as well as the concept of exaptation. Just because a mechanism currently serves a particular function does not mean that this function is what the mechanism originally evolved for. In other words, current function is not necessarily the original function (bird wings were initially adaptations for thermoregulation and later got exapted for flight). Here is the adaptationist statement:

The theorists have long disagreed about one another’s ideas, but most agree on one thing: If nature makes people sleep away so much of their lives, the reason has to be something crucial. That seemed to be the only way to explain why sleep-deprived people crave sleep so badly that they doze off behind the wheel of a car going 60 mph, and why rats deprived of sleep die sooner than rats deprived of food.

The article then trots out a couple of currently favoured hypotheses about the adaptive function of sleep:

Yet a wealth of sleep research has regularly produced baffling paradoxes and conflicting lines of evidence about the uses, role and need for sleep. If sleep is primarily about providing mental rest, why do people’s brains remain so active during sleep, as research in recent decades has found?

If sleep is about providing the body with rest, why do couch potatoes need as much sleep as Olympic athletes? Moreover, animals such as horses, which perform far more physical labor than humans, need much less sleep than people do.

If sleep primarily hones cognitive functions, why do the intellectually lazy need as much sleep as Nobel Prize-winning physicists? Also, why do humans — who are a lot smarter than rats — sleep less than rodents?

Finally, while much conventional thinking suggests that Americans should be sleeping more, a very large 2002 study found that people who sleep eight hours or more a night are likely to die younger than those who sleep seven. (Don’t touch that alarm clock; the study did not find that deliberately sleeping less increases life span.)

Considering that a vast majority of sleep researchers are MDs, not neccessarily up to speed in evolutionary theory, such sentiments are not surprising. It takes an evolutionary biologist to move the ball forward:

Jerome Siegel, a psychiatrist at the University of California at Los Angeles who described these discordant findings in acomprehensive review of the available research, published in the journal Nature last week, said he began to question the notion that sleep performs some essential function after noting that species that sleep less than others do not sleep any deeper — as they would if they were making up for the shorter time. Animals that sleep fewer hours generally sleep less deeply, while animals that sleep longer usually sleep more deeply.

Siegel, a respected sleep researcher who is also affiliated with the Department of Veterans Affairs, said he came to the conclusion there was only one explanation that could explain the paradoxes: in a word, evolution.

Rather than being designed to perform some critical function, Siegel wrote in his paper, sleep may be the way various species, humans included, have adapted to their ecological niches. While many valuable functions probably take place during sleep, Siegel suggested that it is possible that those functions are not the reason for sleep.

“There is this huge variation in sleep across species, and it fits with this huge variation in the niches that animals occupy,” Siegel said in an interview.

“The analogy I make is between hibernation and sleep,” he said. “No one says, ‘What is hibernation for? It is a great mystery.’ . . . It’s obvious that animals hibernate because there is no food, and by shutting down the brain and body they save energy.”

Sleep, Siegel suggested, may play much the same role. As evidence, he cited research that has found systematic differences in the way carnivores, omnivores and herbivores sleep: Carnivores sleep longer; herbivores, shorter; and omnivores, including humans, are somewhere in the middle.

“If animals have to eat grass all day, they can’t sleep a lot, but if they eat meat and are successful at killing an antelope, why bother to stay awake?” he asked.

On the other hand, mammals at greater risk of being eaten — such as newborns — spend large amounts of time asleep, presumably safe in hiding places devised by their parents. Supporting the evolutionary explanation, Siegel’s own research has shown that when the luxury of safe hiding places is unavailable — in the ocean, for instance — baby dolphins and baby killer whales reverse the pattern found among terrestrial mammals. These marine mammals sleep little or never as newborns and gradually increase the amount they sleep as they mature.

Let me put it simply: sleep makes you sit still and be quiet at times when it is dangerous to move around and there is nothing else important to do. All the other functions were added later due to either timing (some things are better done at certain times of day that coincide with either sleep-time or wake-time and the two processes get linked) or particular brain states (i.e., some functions, for instance the consolidation of memory, are easier to perform at times when the brain is NOT receiving much input from the outside environment):

The theory does not so much contradict other theories about the role of sleep as much as place them in context: “What I am saying is that it is not that sleep has been adapted to allow some vital function to be fulfilled, but the core function of sleep is to adapt animals to their ecological niche,” Siegel said. “Given the animal is inactive for a certain period of the day, certain functions will migrate to that period because it is more efficient” to perform them at that time.

Interestingly, this hypothesis does not conflict with an old (and frankly quite unpopular) notion that mammals and birds did not evolve sleep as a new process (after all, insects sleep, we now know), but that they evolved wakefulness as a novel state of the mind.

Insects, fish, amphibians, reptiles etc., have periods of activity and periods of slumber. The period of slumber corresponds to mammalian/avian state of sleep. But, the active state in cold-blooded animals is more similar to sleep-walking than real wakefulness.

Did birds and mammals independently evolve wakefulness or was there a whole suit of (now extinct) reptilian and dinosaurian lineages who were also wide awake? Did evolution of wakefulness provide a substrate for the evolution of consciousness? Interesting speculations, but nothing close to an answer to date. At least, provocative hypotheses by Jerome Siegel and some others are prompting the sleep scientists to reconsider everything they hold dear and therein lies progress.

Siegel’s paper is available online (unfortunately, behind a paywall). Carl Zimmer has an article on this in New York Times.

The Scienceblogging Weekly (May 18, 2012)

Blog of the Week:

For the greatest portion of the history of biology, every organism was a “model organism”. One would pick a problem and then choose which organism would be most suited for answering those particular questions. Then, in the 1990s, everyone jumped onto the bandwagon of studying just a handful of organisms that could be genetically modified at the time: mouse, fruitfly, thale cress, zebrafish, African clawed frog, bread mold, brewer’s yeast, or E.coli. All the other organisms were all but abandoned, only studied by a small number of die-hard researchers and, increasingly, amateurs. Now that technology allows us to investigate (and to some extent manipulate) entire genomes of almost any species we’d like, researchers are going back and rediscovering the abandoned model organisms once again. One of these is Anolis, a large group of species of lizards, noted for their dewlaps, and known especially for their fast adaptive radiation on tropical islands.

And now there is a blog that covers everything about these lizards – Anole Annals. Posts are written both by veteran researchers and their students, from several laboratories, as well as other contributors. They cover both recent and historical papers on evolution, ecology, biogeography, behavior, physiology, biomechanics and genetics of this diverse group of reptiles. They also describe their own research, including anecdotes and adventures from field work, equipment they use in the lab, and successes in discovery. On top of that, they help people ID the species from pictures, pay attention to the appearance of anoles in art and in the popular culture and generally have a lot of fun doing all of this. A blog entirely devoted to just one group of animals sounds very ‘niche’, but what they did was build a blog that has something for everyone and is a great fun (as well as insightful and educational) read for everyone.

The secret molecular life of soap bubbles (1913) by Greg Gbur:

Motherhood, war, and attachment: what does it all mean? by Emily Willingham:

I’m sure many mothers can attest to the following: You have friends who also are mothers. I bet that for most of us, those friends represent a spectrum of attitudes about parenting, education, religion, Fifty Shades of Grey, recycling, diet, discipline, Oprah, and more. They also probably don’t all dress just like you, talk just like you, have the same level of education as you, same employment, same ambitions, same hair, or same toothpaste. And I bet that for many of us, in our interactions with our friends, we have found ourselves judging everything from why she insists on wearing those shoes to why she lets little Timmy eat Pop Tarts. Yet, despite all of this mental observation and, yes, judging, we still manage to get along, go out to dinner together, meet at one another’s homes, and gab our heads off during play dates. That’s not a war. That’s life….

As oxygen filled the world, life’s universal clock began to tick by Ed Yong:

The Earth’s earliest days were largely free of oxygen. Then, around 2.5 billion years ago, primitive bacteria started to flood the atmosphere with this vital gas. They produced it in the process of harnessing the sun’s energy to make their own nutrients, just as plants do today. The building oxygen levels reddened the planet, as black iron minerals oxidised into rusty hues. They also killed off most of the world’s microbes, which were unable to cope with this new destructive gas. And in the survivors of this planetary upheaval, life’s first clock began to tick and tock….

….But sometimes tapeworms take a wrong turn. Instead of going into a pig, the eggs end up in a human. This can occur if someone shedding tapeworm eggs contaminates food that other people then eat. When the egg hatches, the confused larva does not develop into an adult in the human’s intestines. Instead, it acts as it would inside a pig. It burrows into the person’s bloodstream and gets swept through the body. Often those parasites end up in the brain, where they form cysts….

Why Octopuses Should Run Our National Security Infrastructure by Annalee Newitz:

Next time the government wants new ideas about how to protect our nation’s security, it should consult an octopus. That’s the unusual proposition of marine biologist Rafe Sagarin, a pioneer in the infant field of “natural security,” where experts use models from nature to help them come up with emergency responses to everything from terrorist attacks to pandemics. Sagarin has just published a book about his work called Learning from the Octopus: How Secrets from Nature Can Help Us Fight Terrorist Attacks, Natural Disasters, and Disease. Any scientific theory that involves the superiority of cephalopods is automatically intriguing, so I called up Sagarin to talk about it.

Physics’s PR problem: Moving beyond string theory and multiple universes by Ashutosh Jogalekar:

….The problem is that most of the popular physics that the public enjoys constitutes perhaps 10% of the research that physicists worldwide are engaged in. Again, count the number of physics books in your local bookstore, and you will notice that about 90% of them cover quantum mechanics, cosmology, particle physics and “theories of everything”. You would be hard-pressed to find volumes on condensed matter physics, biophysics, the physics of “soft” matter like liquids and non-linear dynamics. And yes, these are bonafide fields of physics that have engaged physics’s best minds for decades and which are as exciting as any other field of science. Yet if you ask physics-friendly laymen what cutting-edge physics is about, the answers will typically span the Big Bang, Higgs boson, black holes, dark matter, string theory and even time-travel. There will be scant mention if any of say spectroscopy, optics, polymers, magnetic resonance, lasers or even superconductivity….

A Brief History and Proposed Definition for ‘Attention Economics’ by Adrian J. Ebsary

Domestication – it’s a matter of time (always is for me, that’s my ‘hammer’ for all nails)

I originally published this post on August 6, 2008.

Since this article came out in The American Scientist in early 1999 (you can read the entire thing here (pdf)) I have read it many times, I used it in teaching, I discussed it in Journal Clubs, and it is a never-ending fascination for me.

Back in the 1950s, Dmitri Konstantinovich Belyaev started an experiment in which he selectively bred Silver Foxes, very carefully, ONLY for their tameness (and “tameness” was defined very rigorously in terms of type and speed of response, distance that triggers aggression, etc.).

What happened really fast in this experiment is that many other traits showed up, seemingly out of nowhere, in the subsequent generations. They started having splotched and piebald coloration of their coats, floppy ears, white tips of their tails and paws. Their body proportions changed. They started barking. They improved on their performance in cognitive experiments. They started breeding earlier in spring, and many of them started breeding twice a year.

Most of the people reacting to this experiment invoked pleiotropy, i.e., how changes in one gene affect expression of many other genes. See this NYT article for instance. However, even while I was reading it for the first time, my mind screamed – development!

And not just development, but more specifically, heterochrony – change in timing of developmental event.

If you alter the expression of one of the genes that affects developmental timing, you affect all sorts of things.

For instance, when the neural crest cells migrate they become melanocytes in the skin – if due to changes in timing they are late to arrive to some distal parts, e.g., paws and tail-tips, those part will be white. Neural crest cells also migrate to become the adrenal medulla – that little part of the body that releases (nor)epinephrine (adrenaline). If fewer of those cells arrive there on time, less the animal will show stress-response later in life.

There appears to be tight correlation between timers that act on different scales, e.g., developmental and circadian timing, circadian and fast behavioral timing, circadian and seasonal timing, etc.

I always wished I could get a lab, some foxes, an IACUC approval and some money to run these animals through a battery of standard experiments comparing dogs, wild foxes and domesticated foxes on all sorts of parameters of circadian rhythms, photoperiodism (they did change their seasonality patterns of breeding, after all), etc.

The bottom line is that a subtle change in timing of expression of a single developmental gene, something one can select for by choosing one of the traits (in this case a behavioral trait), will affect the change in timing of expression in many other genes. The difference between wild and domesticated foxes may not be in any DNA sequence at all – it could presumably be all epigenetic (see also). Sequence differences would arise later, as the two populations are not inter-mixing any more (for over 60 years now).

When you put together development, genetics and evolution, you can see that big changes (or, really, any changes at the very beginning of the evolutionary change) in DNA sequence are not necessary for big changes in entire suites of phenotypic traits. But in the 1950s, the bean-bag deterministic genetics was the norm, so the Belyaev experiment was a big jolt to the scientific community in the West (not so much for the Russian evolutionary biologists, though), so we need to look at this experiment through a decent grasp of history.

Now, I’d like to know what is the state of the experiment today. Ten years ago, the project appeared doomed – they had to sell foxes for fur in order to keep going at a small scale. Has this been fixed? Has anyone from the West help finance the continuation of the project? Has anyone in the West acquired some of the foxes and continued with the project? What are the recent developments?

The Scienceblogging Weekly (May 11, 2012)

In the flood of information, filters are invaluable – people you trust to pick the best so you can focus on that, only that, and ignore the less important stuff.

Editors (including Jason here at the network) at ScienceSeeker.org and editors (including Krystal here at the network) at ResearchBlogging.org filter the best science blog posts each week.

Ed Yong’s weekly linkfests (like this one) and monthly Top 10 choices he’d pay for (see this for an example) are must-bookmark resources.

Some other bloggers are occasional or regular sources of links I pay attention to, e.g., John Dupuis on academia, publishing, libraries and books, Chad Orzel on academia and science – especially physics, Mike the Mad Biologist on science and politics, and the crew at the Knight Science Journalism Tracker for the media coverage of science. And at the NASW site, Tabitha Powledge has a must-read On science blogs this week summary every Friday.

Most of the articles and blog posts I read every day are brought to my attention by my friends on Twitter, Google Plus and Facebook, I get some through email notifications, as well as gleaned from ScienceBlogging.org and ScienceSeeker.org science blog aggregators. I then share a LOT of those links to my followers on Twitter, Facebook and Google Plus every day.

Every workday around midnight I post a linkfest on The Network Central to make it easier to see our network posts if you missed them during the day. Khalil and I take turns highlighting the best work by up-and-coming science writers on The SA Incubator blog. Weekly posting of the ever-growing list of posts submitted for the Open Laboratory is another resource. SciAm homepage is also set as a collection of filters – we decide what goes into “Blogs” box, what in the “Latest News” feed, what in the “Science Agenda” on top of the page, and what to collect into “In-Depth Reports” over time.

Now I will also start a weekly collection of links that are “best of the best” of everything I read over a period of a week – not the posts from #SciAmBlogs, but the rest of the Web: other blogs and other media sites. That means a lot of cutting! I mean, I tweet TONS of links every day! Choosing the best will not come easy to me, so this is a good exercise for me as well, and I hope will become a useful resource to you.

I’ll try to do this every Friday, time of day dependent on travel, work, life etc. Let me know in the comments if you have suggestions for formatting, timing, etc.

The Moscow Rules – Science Edition: Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9 and Part 10 by Zen Faulkes, guest-blogging at Scientopia:

The Moscow Rules were directives that undercover American intelligence agents allegedly used in the Cold War. The rules were there to increase agent’s chances of making it out safely.

Sometimes, being in academic science can feel like being enemy territory in a cold war. You are often in strange territory (new lab), with many unfamiliar people (other grad students, post-docs, faculty) whose motivations are unclear. You might not trust them completely (especially administrators). There might not be the risk of attempted assassination by having poison injected into you with a specially built umbrella, but there’s enough similarity that the Moscow Rules can still apply…

If You Want A Lizard To Run Fast, Yell At It by Jonathan Losos:

…“As you well know, some days things just don’t seem to go well when testing whole animal performance. On one of those days out of frustration, fatigue, etc., we simply yelled at an apparent “slacker” lizard in jest. Much to our surprise this seemed to make a difference. We were also aware of the two recent papers for other species of lizards in which sound appeared relevant to behaviors associated with detecting threats. So, we figured what the heck, why not test for such effects systematically. Unlike many of the studies that you and others have performed with anoles, unless we simply can’t get a lizards to run along the racetrack or they appear unhealthy, we include data from all of the individuals rather than subjectively rating the trials for their quantity. Perhaps, some of the gains in speed associated with our yelling were greatest for those individuals that otherwise might have been discarded after receiving a poor subjective quality rating. Of course, we lack a simple way of determining this. Similarly, we have not yet methodically tested for whether expletives are more effective that milder language.”…

Invisible aliens: they’re not life as we know it — yet by John Rennie:

Both publications posit that life, at its most abstract, involves a thermodynamic disequilibrium. That is, life involves physical structures that can only maintain their integrity with inputs of energy. These physical structures will require covalent bonds between atoms (to allow nontrivial chemical reactions), so the environment in which life appears must allow such chemistry to occur. Some kind of liquid, but not necessarily water, would therefore also be necessary to enable those reactions. Finally, some molecules in the living system would need to be capable of Darwinian evolution for the life to arise. (Take note, creationist doubters of evolution: it is now a useful part of the definition of life!)

From theory and experiments, both papers argue that life with these traits could evolve under a wide (but definitely limited) range of environments. Carbon-based life on worlds with liquid water might represent a particularly versatile and common set of solutions, but biochemistry could go in many directions even on Earthlike worlds. And on planets and moons where terrestrial life would perish instantly, life based on silicon instead of carbon or liquid hydrocarbons instead of water might thrive…

Plastic Lessons by Shara Yurkiewicz:

I always feel awkward when I talk to plastic patients. The simulation mannequins are impressive: their eyes blink, their chests expand as they breathe, they have pulses, they bleed, they burn. A screen monitors vital signs: I administer a pressor and a dipping blood pressure perks up, or I order a beta blocker and a racing heart rate slows. A physician in the next room lends her voice to play the patient, responding to what I do and say. A physician in the same room becomes a tech, relying results of my tests and nudging me through the next steps when I veer off course….

Twilight of the giants in taxonomy by Emmett Duffy:

In an important sense, nothing exists until it’s given a name. And in the living world of organisms, names—official, scientific names—are assigned by unique creatures called taxonomists, experts in the minutiae of structure and biology of particular groups of organisms, working according to a strict and arcane body of rules of biological nomenclature. These individuals tend to be specialists—sages of whales, anglerfishes, microscopic worms that live only between the grains of sand on beaches, microscopic algae, purple sulfur bacteria, and everything in between…

Is Technology Destroying Your Relationships? by A.V.Flox:

Social networks put a number on those weak ties, but we all have weak ties in our meatspace lives. Marche bemoans how we use machines to check out at the grocery store instead of waiting in line with other people to have our purchases rung up by an actual human. But I wonder — even if you were to speak to the woman giving you dirty looks because you were buying a product with a big carbon footprint, can you actually call that a meaningful relationship?

I talk to people all the time — cab drivers, waiters, flight attendants, the guy at the post office, my manicurist, my barista, the boys at the convenience store where I buy my cigarettes, the guy at the newsstand. I am there, in the flesh. Does this mean our connections are any more meaningful than a like or a plus on social media?

Weak ties exist. They’re everywhere. All we have to do to make them meaningful is take the chance to go deeper. This is as true online as it is offline.

What does it mean to say that something causes 16% of cancers? by Ed Yong:

…executives and policy-makers love PAFs, and they especially love comparing them across different risk factors. They are nice, solid numbers that make for strong bullet points and eye-grabbing Powerpoint slides. They have a nasty habit of becoming influential well beyond their actual scientific value. I have seen them used as the arbitrators of decisions, lined up on a single graphic that supposedly illustrates the magnitude of different problems. But of course, they do no such thing…

The Mysterious Case of the Vanishing Genius by Mike Martin:

Margie Profet was always a study in sharp contradictions. A maverick thinker remembered for her innocent demeanor, she was a woman who paired running shorts with heavy sweaters year-round, and had a professional pedigree as eccentric as her clothing choices: Profet had multiple academic degrees but no true perch in academe. In the late 1980s and early 1990s, Profet published original theories about female reproduction that pushed the boundaries of evolutionary biology, forcing an entire field to take note. Indeed, back then it was hard not to notice Margie Profet, a vibrant young woman who made a “forever impression” on grade school chums and Harvard Ph.D.s alike. Today, the most salient fact about Profet is her absence. Neither friends, former advisers, publishers, nor ex-lovers has any idea what happened to her or where she is today. Sometime between 2002 and 2005, Profet, who was then in her mid-40s, vanished without a trace…

Asymmetrical snakes by Andrew Durso:

Animals have a long tradition of being bilaterally symmetrical – that is, of the left side and the right being nearly identical. Sure, there are a few exceptions – the human heart is nearly always farther to the left side, for instance. Snakes and other elongate, limbless animals sometimes stagger their paired organs (gonads, kidneys) so that one is in front of the other, to better fit in their cylindrical bodies. Most snakes have even done away with one of their two lungs. But the basic external body plan, the bones and muscles on the left and the right, are always mirror-images of one another, right?

Enter the pareatid snakes…
