Obligatory Readings of the Day – the Ken Hamm and Beyond edition

First, as I reported earlier, Archy persuaded PZ Myers to host a one-time carnival about the opening of the Creation Museum – and here is the carnival – a lot of good stuff to read.
I especially liked the only (so far) on-the-scene report by Martha Heil.
I also tend to prefer posts that try to take in a Big Picture and place stuff in broader historical and/or geographical context, thus, I really liked contributions by Laelaps and Greg Laden. They are optimistic, though. The view from outside, from Europe, can be much more pessimistic.
Also, some of the comments on this post remind me of my early internet days on various Balkans Usenet groups. Apparently, the tone and quality have not changed much since the early 1990s! I thought that brotherhood and unity were back in vogue again, as evidenced by the results of the Eurovision contest. I only made a quick remark in that direction, but several Euroblogs wrote deeper sociological analyses of the deeper meaning of the Eurovision results and what they portend for Europe’s future. See, for instance, this post and peruse a good linkfest collected by Eric.

ClockQuotes

Ah, Faustus, now hast thou but one bare hour to live
And then thou must be damn’d perpetually!
Stand still, you ever moving spheres of heaven.
That time may cease, and midnight never come;
Fair nature’s eye, rise, rise again and make
Perpetual day; or let this hour be but
A year, a month, a week, a natural day,
That Faustus may repent and save his soul!
‘O lente, lente currite, noctis equi!’
The stars move still, time runs, the clock will strike,
The devil will come and Faustus must be damn’d’

Complexity

Larry just won the Triple Crown (or a trifecta, betting on the Triple Crown) with the third post in a trio of posts on a very important topic:
Facts and Myths Concerning the Historical Estimates of the Number of Genes in the Human Genome
The Deflated Ego Problem
SCIENCE Questions: Why Do Humans Have So Few Genes?
Alex Palazzo, madhadron, Ricardo Azevedo and PZ Myers add thoughtful commentary as well.
Of course, this is something that has been debated and studied (yes, in the laboratory) for a long time by people like Dan McShea so the issue is not going to be solved any time soon with a few blog posts.
But the anthropocentric bias is a big problem in studying and teaching biology and I try to at least briefly discuss the left wall of complexity (as much as it is itself contentious in the literature, I know) and the error of thinking of evolution as progressive (and inevitably leading to humans) when I teach about the origin and evolution of the current biological diversity. I wish it was easier to get that point through.

Do Serbs really want to join the EU?

An interesting poll came out of Gallup yesterday:
Despite Kosovo Intervention, Serbians Favor EU Membership

On May 15, the Serbian parliament approved a new coalition government led by Prime Minister Vojislav Kostunica and President Boris Tadic, both moderates who would like to see their country join the European Union within the next decade. “Serbia’s aspiration to become a full member of the EU is a clearly declared commitment of every party in this coalition,” Kostunica told the parliament prior to confirmation.
However, Serbia’s refusal to compromise on any plan for the future of Kosovo that grants independence to the breakaway province is a stumbling block on the road to EU membership. Kosovo has been administered by the UN since 1999, when NATO ousted Serbian forces that had killed 10,000 ethnic Albanian civilians in the region.
What does the Serbian public think about the EU? Despite that the EU has brokered the Ahtisaari Plan that would grant Kosovo a form of “supervised independence,” 63% of Serbians living in Serbia say they have a “very positive” (24%) or “somewhat positive” (39%) opinion of the role the EU is playing in the Balkan region. A similar number, 62%, say they think Serbian membership in the EU would be a good thing. Just 9% feel it would be a bad thing.

Sure, the brunt of anger is directed at the USA, Warren Christopher, Madelaine Albright and Wes Clark (and at the domestic war criminals as well, including Milosevic, who should have offered his hospitality to the aforementioned trio in his cell in The Hague), not the Europeans which are natural neighbors, allies, friends and business partners. America is a far-away continent somewhere at the edge of the world map and can be safely ignored, but Europe is where the country is, so one better play nice with the EU.
Also, many see the 1990s as a temporary interruption in the road to EU membership. Back in the late 1980s, when Belgrade almost got to host the ’92 Olympics (lost to Barcelona in the last voting round), Yugoslavia was first in line to join the union. Many there see the renewed effort as a continuation of that process. After all, if they are now all lovey-dovey with the other ex-Yugoslav republics (of which Slovenia is already now an EU member) after they went to war against them, why treat EU as an enemy?

There is less consensus on whether the Serbian government is doing everything necessary to join the EU. Just under half (48%) of Serbians feel it is, while 37% say it isn’t. One possible factor in these perceptions is the ongoing failure of the Serbian government to locate and arrest war crimes fugitive Ratko Mladic. In May 2006, the EU suspended talks on the first steps toward membership, declaring that negotiations would not resume until Mladic was in custody.

No surprise, after a strange and prolonged election earlier this year. Everyone is looking askance at the leadership.

Results are based on face-to-face interviews conducted during February 2007 with randomly selected samples of 1,566 Serbians aged 15 and older. For results based on this sample, one can say with 95% confidence that the maximum error attributable to sampling and other random effects is ±3 percentage points. In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.

This is troubling – face-to-face? This means that most of the people interviewed were in big cities: Belgrade and perhaps (hopefully!) a few other big cities like Nis, Novi Sad or Kragujevac. I doubt that the Gallup people trekked into the mountains to interview people in tiny villages.
The entire 1990s wars of the Balkans were wars between city and country, between an urban, modern, democratic, liberal, pro-European mindset held by people who are educated, speak foreign languages and travel abroad, and the rural, illiterate, backwards, conservative, patriarchal, nationalistic, religious-fundamentalist mindset held by people living in small places. Sorta like the Red/Blue divide in the USA. It was the local conservatives of various ethnicities who joined the paramilitary groups and faught each other, while the local liberals remained in the cities or fled the country. Bombings of Vukovar, Sarajevo and Dubrovnik were bombings of cultural and social elites (of many ethnicities living together) by the drunk peasants from one ethnic side or another. Bombing of Belgrade by NATO was exactly the same thing.
Kosovo is historically the cradle of Serbia. A millenium ago Serbia was Kosovo – it is only the later wars and realignments that gave Serbia additional territory to the north, including Belgrade. All the churches, monasteries and monuments that define Serbian statehood are located in Kosovo. The emotional atachment is completely understandable.
Imagine if Virginia decided to secede from the USA and the entire rest of the world threatened military – including nuclear – intervention (on top of cessation of all trade) in case the US government interfered with the secession? Can you imagine the emotions this would elicit?
A century ago, Kosovo was inhabited by Serbs and Albanians in about a 9:1 ratio. Differences in birthrates, slow emigration of Serbs over decades for economic reasons (Kosovo is the poorest region of the former Yugoslavia), and the ethnic cleansing of Serbs at the hands of KLA in the 1980s (that was the first use of the term in history – Milosevic rose to power by promising to stop it and protect the local Serbian population) completely reversed that ratio to 1:9. Finally, in 1999, almost all of the rest of the Serbs fled Clark’s bombs and depleted uranium, leaving only tiny scatterings of Serbs still living in the province.
So, what is one to do? The rural folks, who have nothing personal to be proud of, who suffered group-related humiliation for a decade (demonization of Serbs by the western media, loss of territory, getting cleansed out of Croatia and Bosnia, finally getting bombed, while Milosevic gave up on everything one thing at a time) have only one thing to cling to – Kosovo. Defending it to the bitter end. It is a matter of ego.
But the urban folks – those who were likely the majority of interviewees in this poll – are pragmatic. They can afford to, because they have individual, personal strengths to keep their self-esteem. They are educated, perhaps successful in business, politics or academia. They are capable of losing Kosovo without losing their identities (and without losing their minds). They see Kosovo as a thing of the past and EU as the future, and future is more important.
So, I’d like to see a poll that carefully differentiates between urban and rural folks (party affiliation may be a better indicator than actual physical address, as many of the rural folks are now refugees in big cities) before I agree that the Serbian population as a whole is so enthusiastic about joining the EU.

Sleep Genes are not the same as ‘Genes for sleep’

Back in the late 1990s, when people first started using various differential screens, etc. looking for elusive “genes for sleep”, I wrote in my written prelims (and reprinted it on my blog several years later):

Now the sleep researchers are jumping on the bandwagon of molecular techniques. They are screening for differences in gene expression between sleeping and awake humans (or rats or mice), searching quite openly for the “genes for sleep”. Every time they “fish out” a gene, it turns out to be Protein kinase A, a dopamine receptor, or something similar with a general function in the brain. Don’t they understand that sleep (like hibernation) is an emergent property of a multicellular brain? Unlike in the clock field, a single neuron does not carry the function – it does not sleep. Only whole (or halves of) brains can be asleep or awake. The sleep “mechanism” is not a molecular mechanism but a result of a particular pattern of neural connectivity and activity.

And, lo an behold, all the genes that affect sleep (the duration or quality of it, not timing which is guided by the circadian clock), turned out to be those “maintanance” molecules, involved in general, day-to-day activity of neurons. Most geneticists have since moved away from such a simplistic, bean-bag genetics notion of sleep and started studying sleep from a much more integrative perspective. But some persist. The newest discovery of a “sleep-gene” is just like what I predicted, a general-maintanance molecule – an ion channel:
Second Sleep Gene Identified:

A gene that controls the flow of potassium into cells is required to maintain normal sleep in fruit flies, according to researchers at the University of Wisconsin School of Medicine and Public Health (SMPH). Hyperkinetic (Hk) is the second gene identified by the SMPH group to have a profound effect on sleep in flies.
The finding supports growing evidence that potassium channels–found in humans and fruit flies alike–play a critical role in generating sleep.
“Without potassium channels, you don’t get slow waves, the oscillations shown by groups of neurons across the brain that are the hallmark of deep sleep,” says Chiara Cirelli, SMPH psychiatry professor and senior author on the latest study, which appeared in the May 16, 2007, Journal of Neuroscience.

Very cool and important for the advancement of our understanding of sleep, but surely not a “gene for sleep”.

New Genetic Data Overturn Long-held Theory Of Limb Development:

Long before animals with limbs (tetrapods) came onto the scene about 365 million years ago, fish already possessed the genes associated with helping to grow hands and feet (autopods) report University of Chicago researchers in the May 24, 2007, issue of Nature. This finding overturns a long-held, but much-debated, theory that limb acquisition was a novel evolutionary event, requiring the descendents of lobed-fin fish to dramatically alter their genes to adapt their bodies to their new environments of streams and swamps.

Archaea In Hot Springs Use Ammonia For Energy: May Shed Light On Early Evolution:

Discovered in the late 1970s, archaea are one of the three main branches on the tree of life, with bacteria and eukaryotes such as plants and animals on the other two branches. But scientists are just now gaining a fuller understanding of what archaea do — in an ecological sense — to make a living. A new study led by University of Georgia researchers and announced on Wednesday at the American Society for Microbiology meeting in Toronto finds that crenarchaeota, one of the most common groups of archaea and a group that includes members that live in hot springs, use ammonia as their energy source. Chuanlun Zhang, lead author of the study and associate research scientist at UGA’s Savannah River Ecology Laboratory, said such a metabolic mode has not been found in any of the other known high-temperature archaea.

‘Radiation-eating’ Fungi Finding Could Trigger Recalculation Of Earth’s Energy Balance And Help Feed Astronauts:

Carolus Linnaeus’ Floral Clocks

When it’s someone’s birthday it is nice to give presents, or a flower. Perhaps a whole boquet of roses. But if the birthday is a really big round number, like 300, and the birthday boy is the one who actually gave names to many of those flowers, it gets a little tougher. Perhaps you may try to do something really difficult and build, actually plant, a Flower Clock. After all, it was Carl von Linne, aka Carolus Linnaeus, today’s birthday celebrator, who invented the flower clock. He drew it like this, but he never actully built one:
flower%20clock%20linnaeus.jpg
The first one to make (and write down) an observation that some plants (in that case, a tropical Tamarind tree) raise their leaves during the day and let them droop down during the night, was Androsthenes, an officer who accompanied Alexander the Great. In the first century, Pliny the Elder made a similar observation, repeated in the thirteenth century by Albertus Magnus.
In 1729, Jean Jacque d’Ortous de Mairan, an astronomer, not a botanist, reported an experiment – considered to be the first true chronobiologial experiment in history – in which he observed the spontaneous daily rise and nightly fall of leaves of Mimosa pudica kept in a closet in the dark. The experiment was repeated with some improvements by Duhamel de Monceau and by Zinn, both in 1759.
Another Swede, Arrhenius argued that a mysterious cosmic Factor X triggered the movements. Charles Darwin published an entire book on the Movement of Plants, arguing that the plant itself generates the daily rhythms. The most famous botanist of the 19th century, Pfeffer, started out favouring the “external hypothesis”, but Darwin’s experiments forced him to change his mind later in his career and accept the “internal” source of such rhythmic movements. In the early 20th century, Erwin Bunning was the first to really thoroughly study circadian rhythms in plants. For the rest of the century, animal research took over and though there has been some progress recently, the understanding of clocks in plants still lags behind that of Drosophila and the mouse.
But it was Carolus Linnaeus back in the 18th century who, fond of personifying plants (mostly in regard to sex) named this phenomenon “sleep” in plants. Soon, he switched his focus from movements of leaves to the daily opening and closing of flowers and performed a broad study of the times of day when each flower species opened and closed:

Linnaeus observed over a number of years that certain plants constantly opened and closed their flowers at particular times of the day, these times varying from species to species. Hence one could deduce the approximate time of day according to which species had opened or closed their flowers. Arranged in sequence of flowering over the day they constituted a kind of floral clock or horologium florae, as Linnaeus called it in his Philosophia Botanica (1751, pages 274-276). A detailed and extended account of this in English will be found in F.W.Oliver’s translation of Anton Kerner’s The Natural History of Plants, 1895, vol.2, pages 215-218. As many of the indicator plants are wildflowers and the opening/closing times depend on latitude, the complexities of planting a floral clock make it an impractical proposition.

While it is not easy to make a functioning flower clock, people have done it. There is one in his hometown of Uppsala, for instance. It has been made in the classroom (pdf) and one can pretty easily find locally useful lists of plants to try to build one.
flowerclocklarge.jpg

Linnaeus; in writings titled Philosophia Botanica wrote about 3 types of flowers:
1. Meteorici, A category which changes their opening and closing times according to the weather conditions.
2. Tropici, Flowers which change their opening and closing specifically to the length of the day.
3. Aequinoctales, Most important here to this story, are the flowers having fixed times for opening and closing, regardless of weather or season.

It is only those last ones that could be used for buildiing Floral Clocks, while the first two groups were important for the studies of vernalization and photoperiodism in plants in the early 20th century.
flower%20clock%20schematic.JPG
You can find some more detail of the flower clock history here. And the idea of a flower clock was also picked up by artists of various kinds:

Linnaeus’s idea for a collection of flowers that opened or closed at a particular time of day was taken up by the French composer Jean Fran aix in his composition L’horloge de flore (The Flower Clock), a concerto for solo oboe and orchestra.

A floral clock features in the fictional city of Quirm, in Soul Music, one of the books in Terry Pratchett’s Discworld series.

Linnaeus Birthday Celebration

As promised, I will gather here (and update a couple of times during the day) some of the most interesting posts from around the blogosphere about the celebrations of the 300th birthday of Carl von Linne aka Carolus Linnaeus, the guy you cussed at when, back in high school, you had to memorize the order of taxonomic categories: Kingdom, Phylum, Class, Order, Family, Genus and Species (and you all know the mnemonic, don’t you?).
So, what’s with the name? Is it Linnaeus or von Linne? Merriam-Webster explains:

But today we come not to praise Linnaeus but to parse his various names. When Linnaeus was born, surnames were not common in Sweden. His father had been known as Nils Ingemarsson (Nils, son of Ingmar) until he attended the University at Lund with the goal of becoming a clergyman. Needing a proper surname, Nils gave himself the Latinized name Linnaeus, after the Linden tree on the family property (which was a warden tree, a very old tree believed to protect the land and people from bad luck).
So when Carl was born, he was given the surname Linnaeus. When he, in turn, enrolled at his father’s alma mater, he registered in full Latin form: Carolus Linnaeus. Then, in 1761, after he had earned some measure of renown for his work Latinizing and simplifying scientific nomenclature, Linnaeus was raised to the rank of nobility and took yet another name: Carl von Linne.

The main webpage for the tricentennial celebration is here. But let’s now move to blogs….

One In Six European Mammals Threatened With Extinction:

The first assessment of all European mammals, commissioned by the European Commission and carried out by the World Conservation Union (IUCN), shows that nearly one in every six mammal species is now threatened with extinction. The population trends are equally alarming: a quarter (27%) of all mammals has declining populations and a further 33% had an unknown population trend. Only 8% were identified as increasing, including the European bison, thanks to successful conservation measures.

Scientists Concerned About Effects Of Global Warming On Infectious Diseases:

As the Earth’s temperatures continue to rise, we can expect a significant change in infectious disease patterns around the globe. Just exactly what those changes will be remains unclear, but scientists agree they will not be for the good.

Whales, dolphins and porpoises (cetaceans) are facing increasing threats from climate change, according to a new report published by WWF and the Whale and Dolphin Conservation Society.

Scientists Evolve New Proteins From Scratch:

Nature, through the trial and error of evolution, has discovered a vast diversity of life from what can only presumed to have been a primordial pool of building blocks. Inspired by this success, a new Biodesign Institute research team, led by John Chaput, is now trying to mimic the process of Darwinian evolution in the laboratory by evolving new proteins from scratch. Using new tricks of molecular biology, Chaput and co-workers have evolved several new proteins in a fraction of the 3 billion years it took nature.

Reason For Mammals’ Aging Lies In The Brain:

To date, there are two basic concepts of reasons for aging. The first one is death as a result of damage accumulation, and the second is death as a suicide program. There are multiple arguments in favour of both concepts. A new – astrocytic – hypothesis has been put forward by Aleksei Boyko, Ukrainian researcher, specialist of the National Agrarian University of Ukraine. In the framework of this hypothesis, aging is treated as a result of changes in cerebrum cells. The key role is played by transmutation of cells of the radial neuroglia into stellate cells – astrocytes. Since such cell transmutation is a programmed process, the researcher is inclined to the opinion that aging and following death have been programmed.

Is That Your Jet-Lag Treatment Showing or are you just Happy To See Me?

Blogging on Peer-Reviewed Research

If this gets more widely known (and, with this post, I am trying to help it become so), you can just imagine the jokes about the new challenges to the aviation industry and the renewed popularity of the Mile High Club, or the cartoons utilizing the phallic shape of airplanes!
Hamsters on Viagra Have Less Jet Lag, Research Shows (also Viagra helps jet-lagged hamsters, maybe humans, too: study and Viagra ‘improves jet lag’):

Hamsters given Pfizer Inc.’s Viagra adapted more quickly to changes in their internal clocks, scientists said.
Hamsters given sildenafil, the chemical name of the drug sold as Viagra, adapted more easily to altered patterns of light exposure to simulate changes caused by air travel across time zones. Long-haul travel desynchronizes the body’s alignment to the day-night cycle, leading to the disorientation of jet lag.
————snip—————-
The researchers synchronized the hamsters to a 24-hour day by simulating light-dark cycles. Once the hamsters adjusted to a cycle, they shifted the light-dark phases forward six hours. One group of hamsters was given saline; the other was given Viagra. The hamsters given Viagra got used to the change 4 days faster, on average, than their counterparts given a placebo. Viagra eased the transition that mimicked crossing the international dateline from west to east, known as phase advancing, and had no effect on a transition that mimicked westward travel.

There should be a rule in journalism making sure that no article about Viagra ever contains the words “harder” and “screw”, especially close to each other. Oooops!

“All animals, including humans, have a harder time with phase advancing,” said Colwell in a telephone interview today. “Humans are unique in our ability to screw up our timing system — you know, jet lag, shift work, staying up too late playing video games, or whatever.”

OK, now seriously…what does the study say?

Linnaeus Tricentennial tomorrow

Tomorrow is 300th birthday of Carl von Linne (or Carlus Linnaeus) and there will be celebrations in Sweden and around the world. So, tomorrow is a good day for a post about him (and if I find enough time and energy, I may compile the best ones into a mini-carnival).

The first masked villain

Remember just the other day when I posted about Arsene Lupen, one of my childhood heroes? OK, Sherlock Holmes (called Herlock Sholmes for copyright reasons in the Lupen books) was a greater hero – there is probably not a single book or story I have not read at least once in my life.
I could also remember there was another French one, but I forgot his name so I omitted him from my post. I could recall the smell and sight of the beautiful new hardcover translations, and how my mother and her friends looked down on them and would not believe me that the books were well-written, smart and exciting. But I could not recall the name of the villain that was the main character of the series. And now, after about 30 years that I never thought about or heard about him, I found it on a blog by sheer coincidence – his name is Fantomas! (via). The books were publised starting in 1911 and it may have been the first masked villain in literature.

Ken Ham Carnival!

You may have heard that Ken Ham is opening his freak show circus Museum of Creation “Science” in Cincinnati on May 28th. There will be protesters picketing. Hopefully there will also be people who will come in and laugh out loud at each exhibited piece. I also hope that the media coverage will be funny – and that is where we in the blogosphere can help.
Archy has all the information about it and has suggested a one-day carnival (an apt name for the thing, for once) of sorts which will appear on May 27th on Pharyngula.
So, write something and send the Permalink to PZ or blogswarm it by linking to the carnival. PZ will actually take the best quotes from each entry – a good idea if the blogswarm brings the carnival up high on the Google searches that day when all the journalists are trying to cover the story.
If you are better at drawing or photoshopping than writing, Left ‘Toon Lane is organizing a cartoon contest for the occasion and PZ will showcase those as well.
Now go, be creative and have fun!

My Picks From ScienceDaily

Sleep Apnea Patients Have Greatly Increased Risk Of Severe Car Crashes:

People with obstructive sleep apnea have a markedly increased risk of severe motor vehicle crashes involving personal injury, according to a new study. The study of 800 people with sleep apnea and 800 without the nighttime breathing disorder found that patients with sleep apnea were twice as likely as people without sleep apnea to have a car crash, and three to five times as likely to have a serious crash involving personal injury. Overall, the sleep apnea group had a total of 250 crashes over three years, compared with 123 crashes in the group without sleep apnea.

How Rabies Spreads In A Raccoon Outbreak:

Analyzing 30 years of data detailing a large rabies virus outbreak among North American raccoons, researchers at Emory University have revealed how initial demographic, ecological and genetic processes simultaneously shaped the virus’s geographic spread over time.

Prehistoric Behavior And Ecology Of Northern Fur Seals Reconstructed:

A team of researchers has documented major changes in the behavior, ecology, and geographic range of the northern fur seal over the past 1,500 years using a combination of techniques from archaeology, biochemistry, and ecology. Among their findings is evidence of reproductive behavior in the past that is not seen in modern populations of northern fur seals.

Biologist Hopes Mosquito Can Break Viral Chain:

Most people do their best to avoid mosquitoes. But this summer Rollie Clem will play the wary host to his own homegrown swarm of Aedes aegypti, the yellow fever mosquito. He’s made a room ready for them, and even a menu.

Diversity Tonight

No more blogging until late tonight or tomorrow morning as it is a Monday and on Monday evenings I teach. Today’s topic is Biological Diversity, from its origins through its evolution to its current state. Fun!

My Picks From ScienceDaily

Fused Nasal Bones Helped Tyrannosaurids Dismember Prey:

New evidence may help explain the brute strength of the tyrannosaurid, says a University of Alberta researcher whose finding demonstrates how a fused nasal bone helped turn the animal into a “zoological superweapon.”

Jet Lag, Circadian Clocks Explained:

Circadian clocks regulate the timing of biological functions in almost all higher organisms. Anyone who has flown through several time zones knows the jet lag that can result when this timing is disrupted. Now, new research by Cornell and Dartmouth scientists explains the biological mechanism behind how circadian clocks sense light through a process that transfers energy from light to chemical reactions in cells. Circadian clocks in cells respond to differences in light between night and day and thereby allow organisms to anticipate changes in the environment by pacing their metabolism to this daily cycle.

OK, one more little piece of the puzzle is in – it does not mean that everything is “explained” as the title suggests….
Bigger Is Smarter: Overall, Not Relative, Brain Size Predicts Intelligence:

When it comes to estimating the intelligence of various animal species, it may be as simple measuring overall brain size. In fact, making corrections for a species’ body size may be a mistake. The findings were reported by researchers at Grand Valley State University and the Anthropological Institute and Museum at the University of Zürich, Switzerland. “It’s long been known that species with larger body sizes generally have larger brains,” said Robert Deaner, assistant professor of psychology at Grand Valley and the first author on the study. “Scientists have generally assumed that this pattern occurs because larger animals require larger nervous systems to coordinate their larger bodies. But our results suggest a simpler reason: larger species are typically smarter.”

Conferences should be more spread out….

First, I tentatively reserved a spot for myself for the Science Foo Camp on August 3-5, 2008 in Mountain View, CA.
Then, there is nothing for a long time, then three conferences I want to go to, and for all three I have some degree of negotiations about presenting about Open Science or science blogging or in some way being involved, and all three are almost simultaneous:
ConvergeSouth 2007 in October 19-20, 2007, in Greensboro, North Carolina.
The 2007 Microsoft eScience Workshop at RENCI at the Friday Center in Chapel Hill, NC on October 21-23, 2007
ASIS&T: Joining Research and Practice: Social Computing and Information Science on October 18-25, 2007 in Milwaukee, Wisconsin
Perhaps I can finagle to go to Greensboro for two days, Chapel Hill for two days and Milwaukee for two days – my wife is gonna kill me for abandoning her with the kids for so long while I schmooze with interesting people!
Then again, nothing for a long time until the North Carolina Science Blogging Conference, at Sigma Xi, RTP, on January 18-19, 2008.
Unfortunately, I found no sponsor to go to this next week. Ah well, it turned out to be far too molecular for my taste anyway.

Some very old beer…

Via Snarkmarket, I found this (probably incomplete) Wikipedia list of the oldest companies in the world that are still operating today under the same name. The oldest one, a construction company in Japan called Kongō Gumi, just went belly-up after serving their customers since the year 578AD.
And according to a commenter there, the oldest University in continuous operation is University of Al Karaouine in Fes, Morocco.
The oldest company on the list from the Balkans is Apatinska Pivara which has been brewing beer continuously since 1756. They produce one of the most popular local beers, the Jelen Pivo (although, both in the region and for emigrants like me, the champion is Montenegro’s Niksicko Pivo, both the pilsner and the stout).
WWII and the subsequent nationalization of all sorts of businesses makes it unlikely that many old companies continued under the same name afterwards, but I cannot believe that only one beer brewery made the list. Anyone here from the Balkans can think of (and verify) some other companies with a long tradition?

Arsene Lupen

This brief story on NPR today reminded me of some books I read as a child (in Serbo-Croatian translation) – though I have to admit that my brother loved them even more – in which the main character is Arsene Lupen, the art connoisseur and gentleman burglar. Listen to the NPR podcast and get the books – they are great! How well known is this character in the USA? Perhaps through his anime grandson?
