Deepwater Horizon oil spill interrupted bluefin tuna spawning

According to a new paper showing temporal and spatial patterns of migratory routes and spawning grounds of bluefin tuna, they were in the Gulf of Mexico spawning at the moment the oil well exploded and all that oil started gushing out (and then dispersed with toxic chemicals).
Nobody is fishing there now, and no professional media or amateur reporting or photography are allowed, but I am assuming some of the radiotransmitters in some of the individuals may still be operational and that data from the area, during the spill, will become available in the future.

New and Exciting in PLoS this week

Over the past week or so, PLoS IT/Web team made some serious upgrades to the site, including a much better, faster search – go and test it! Friday is also the time to point out cool new papers from four out of seven PLoS journals. As always, you should rate the articles, post notes and comments and send trackbacks when you blog about the papers. You can now also easily place articles on various social services (CiteULike, Mendeley, Connotea, Stumbleupon, Facebook and Digg) with just one click. Here are my own picks for the week – you go and look for your own favourites:

Why is some coverage of scientific news in the media very poor?

Ever have one of those times when you have a cool new blog post all ready in your head, just needs to be typed in and published? Just to realize that you have already published it months ago? Brains are funny things, playing tricks on us like this. I just had one of such experiences today, then realized that I have already posted it, almost word-for-word, a few months ago. It’s this post. But something strange happened in the meantime: that post, in my head, got twice as long and changed direction – I started focusing on an aspect that I barely glossed over last time around. So perhaps I need to write this one anyway, with this second focus of emphasis and instead of retyping the first half all over again, just ask you to read the old post again as it provides background necessary for understanding this “Part II” post today. I’ll wait for you right here so go read it and come back….

Are you back?

OK, so, to reiterate, about four or so months ago, I started monitoring media coverage of PLoS ONE papers and posting weekly summaries and linkfests on the everyONE blog. In the previous post (the one you just read and then came back here) I focused on the importance of linking to the papers, and why bloggers tend to provide links while traditional media does not. There is also a good discussion in the comment thread there. Here, I’ll shift focus on the quality of coverage instead.

Expectations before I started:

Before I was given this task, I was already, of course, aware of a lot of coverage, just not in a systematic way. After all, I needed to read the coverage on science blogs in order to make my monthly pick.

Reading science blogs of repute, or those editorially approved by the editors of ResearchBlogging.org, or those editorially chosen to join the networks like Scienceblogs.com or Discover, I assumed that I was predominantly seeing the best of the best of bloggy coverage of science stories and that there is probably some lesser stuff out there that I just did not pay attention to. If I noted some really bad coverage, I usually discovered it via science blogs on posts that debunked them – such bad coverage I saw tended to come from specialized anti-science or pseudoscience blogs whose political agenda is to misrepresent scientific findings in a particular area of science (e.g., blogs of Creationists or Global Warming Denialists). I assumed that there was also a bunch of stuff in the middle, OK but not brilliant.

Likewise, without specifically looking for coverage in traditional media, such coverage would often find me, either if a blogger linked to it, or via TwitterFriendfeedFacebookverse. Again, it was either excellent coverage of a big story of the week, or such egregiously wrong explanation that it was the duty of science bloggers to do the fact-checking and correcting in a public place – their blogs – so the audience googling the topic would hopefully see those corrections. Again, I assumed I saw only the best and the worst and that there must be a lot of middlin’ stuff in-between.

So, if I designed a scale to measure the quality of reporting, ranging from Amazing to Excellent to Very Good to Good to Average to Meh to Poor to Atrocious, I expected to see both blog posts and MSM articles spanning the entire scale in pretty proportional distribution, more of a flat line than a bell curve.

That’s not what I found.

What I found surprised me….and depressed me.

So, let me classify coverage by quality:

1) Anti-coverage.

Anti-science and pseudoscience blogs actually rarely post about specific scientific papers. They are essentially political blogs, and thus most of their posts are broad, opinionated rants. When they do target a new paper, they tend not to link to the paper, which makes it difficult for me to find the post in the first place (my previous post describes detailed methodology I use to find the coverage).

There is plenty of anti-science and pseudoscience ranting in what goes under the heading of traditional media as well. Just like blogs, they tend to make broad opinionated rants and not focus on specific papers. HuffPo is notorious for pushing medical quackery and pseudoscientific NewAge-style woo. The things that look like media but are just well-funded AgitProp fronts for RightWing organizations sometimes focus on science they hate, especially Global Warming which they deny. Interestingly, unlike their cable counterpart which is pure ideological propaganda, the FoxNews website has relatively decent science coverage as far as traditional media goes.

It does not matter to me that many of those outlets are indexed in Google News – PLoS is a serious scientific organization and I will not reward anti-science forces with a link from our blog or legitimize them by mentioning them.

2) Non-coverage.

Some blogs are personal RSS-feed aggregators, automatically importing feeds from various sources, or with specific keywords. If those include links to the original, they are legitimate, if there are no links, they are splogs (spam-blog), but either way they are useless – that is not coverage of our papers, so I ignore it. In case of a very big story, sometimes I see a blogger who is not a science blogger post something about it – usually just a copy and paste of some text from ScienceDaily, rarely with any editorializing (e.g., a funny title, or a LOL-cat-ized picture) – also not to be considered original coverage, thus ignored safely by me.

Likewise, often dozens or hundreds of newspapers copy and paste (sometimes abbreviated) text coming from AP or Reuters or AFP or TASS. They are essentially equivalent to feed-blogs (since they usually say that this was from Reuters, etc.) or even splogs (since they never link to the original scientific paper) and only a technicality saves them from being considered outright plagiarism. Thus, I link to the Reuters original (which since recently started adding links to papers – Yay!!!) and safely ignore all the others – they are not considered coverage.

Sites like EurekAlert! and ScienceDaily collect barely modified press releases. If I can find the original press release on the University site I may link to it in my weekly post, but I do not link to these secondary sites – they are just aggregators, not sources of original coverage.

3) Poor-to-average coverage.

This comes 100% from the traditional media. Bloggers are either experts – scientists themselves (or science teachers or science writers) – and thus do a good job, or are not experts in which case they are not interested in science, do not blog about it, and certainly have nothing to say even if they copy+paste something sciencey from the MSM. So they don’t even try to write original blog posts with their own opinions. The middlin’ gray area just does not seem to appear on blogs. But there is tons of it in the MSM – the range of my quality scale from Average down to Atrocious is filled with MSM articles. They are bad, but they are “original reporting” at least to some extent (though probably warmed-up press releases, rewritten to use different words and phrases) so I include the links in my posts anyway.

4) Good to excellent coverage.

This is interesting. Many PLoS ONE papers get covered on blogs, and are usually covered wonderfully well. On the other hand, good MSM coverage happens only for the Big Papers, those that are covered everywhere (like Nigersaurus, Maiacetus, Green Sahara, Darwinius….). And then, those excellent MSM articles are written by well-known science writers in top media outlets (e.g., Guardian, London Times, NY Times….). Traditional media pull their Big Guns only for a rare Super-Paper, while bloggers cover everything well, big or small – whatever is their interest or area of expertise. Finally, I should point out that the websites of magazines and public radio (NPR or PRI) tend to cover science better than the websites of newspapers and TV outlets. At the latter, science is covered better by their resident bloggers than by the main news-site.

Why does PLoS treat bloggers as journalists, has bloggers on press list, and highlights the blog coverage? You can say we are nimble and ‘get it’, or that we want a perception of being cutting-edge, or that we’ll try to get whatever coverage we can get. But really, the most important reason we do this is because the coverage of our papers by bloggers is just plain better than MSM, and significantly more so.

So, when British Council only suggests science pages of newspapers for science coverage, or when KSJ Tracker puts together linkfests of coverage of science stories that is composed entirely of media organizations that existed 20 years ago, they are not just out-dated (and thus look like dinosaurs), they miss the very best coverage out there.

What is the difference between Good and Poor coverage?

I have been looking and looking and looking….and I think I finally figured it out. Scientific expertise or experience in covering science by the journalist (or blogger) is a relatively small factor in determining the quality of the article. Much more important is availability of space! Bad articles are short, good articles and blog posts are long.

A couple of inches is just not enough to cover a new scientific paper properly.

Let’s dissect this in more detail….piece by piece.

Lede – an MSM article will always start with it. But from a blogger’s sensibility, lede is weird. Strange. Artificial. Unnatural – nobody really talks like that! It is also superfluous – a fantastic waste of limited space. And it also feels so pretentious: if you are reporting on a scientific story, why start with a paragraph hinting you think you are some kind of Tolstoyevsky? Bloggers either jump straight into the story with a declarative introductory sentence, or start with providing context (including copious use of links) or occasionally start with a joke or personal story or a funny picture, then segue into the serious coverage (but bloggers have endless space so they can afford to waste some of it).

Human Interest paragraph – an MSM article always has it. Bloggers will have it if there is a strong human interest aspect to the story (though never interviewing Average Joe on the street to get a useless quote). Science stories are either “cool” or “relevant” or “fishy”. The latter two often have a human interest aspect to it which a good article and blog post with explore. But many ‘cool’ stories do not – the human interest starts in the reader’s mind while reading the story – the human interest is in reading the story about cool animal behavior or some wonder of the cosmos. There is no need to artificially invent a human interest aspect to such stories – those are often misleading, and always a waste of space.
Main conclusion of the paper paragraph – of course bad articles, good articles and good blog posts will have the main conclusion clearly spelled out. But good articles and blog posts have sufficient space to explain those conclusions – from methodology (is it trustworthy, novel, creative…), to authors’ conclusions (do they follow from the data, miss some important alternative explanation, or over-speculate). They have enough space to explain how those conclusions differ from similar conclusions reached by previous studies, etc. A brief article has no space for this, thus the summary conclusion is either too blunt and short to be accurate, or is too similar to conclusions that the reader has already encountered many times before.

Context – there is no space for context in a short article. Yet it is the context that is the most important part of science coverage, and of science itself – remember the “shoulders of giants”? Placing a new study within a historical, philosophical, theoretical and methodological context is the key to understanding what the paper is about and why it is important, especially for the lay audience. Even scientific papers all provide plenty of context in the Introduction portion (and often in the Discussion as well) which is sprinkled with references to earlier studies.

Quotes – even the shortest article will have a brief quote from one of the authors and/or another scientist in the field, as well as sometimes another scientist who is a naysayer or skeptical about the results. Names of these people who are quoted are usually completely unfamiliar to the lay reader, so invoking them adds no heft to their claims. This is pure HeSaidSheSaid journalism and, again, a colossal waste of space. Not to mention that there are no links to the homepages or Wikipedia pages of these quoted scientists for the audience to see who they are. And we know that a cherry-picked quote that does not link to the entire transcript or file of the interview is a huge red flag and sharply diminishes reputation and trust of the reporter and the media outlet.

Why don’t science bloggers quote other scientists? Why should they? A science blogger is simultaneously both a reporter and a source. If there is a new circadian paper that I find interesting enough to blog about, I am both reporting on what other scientists did AND am a source of expertise in evaluating that work. Why quote someone else when my entire post is essentially an interview with myself, the expert – not just a quote but the entire transcript? The chances I will get something wrong about a paper in my own field are tiny, but if it happens, other people in the field read my blog and they will be quick to correct me in the comments (or via e-mail, yes, it happened a couple of times and I made corrections to the posts). Why add redundancy by asking yet another expert on top of myself?

So, a brief article contains a lot of unnecessary stuff, while it leaves out the most important pieces: the details of methodology and the context. Those most important pieces are also most interesting, even to a lay reader – they situate the new study into a bigger whole and will often prompt the reader to search for more information (for which links would be really useful).

If you are a journalist whose editor gave you plenty of space to cover a Big Story, you can have all of the above in your article, which makes it good. If you are writing for a magazine, it is to be expected you will have plenty of space to give the study sufficiently complete coverage. If you are a blogger, space is not an issue so you just write until you are done. When the story is told, you just end the post and that is it.

But if you are a beat reporter with gazillions of stories to file each week, under tight deadlines, and a couple of inches for each story, then at least try to think how to best use the space you got – is that lede really necessary? The quotes? Can you squeeze in more context instead? And end with a URL to “more information on our website”? Then write (or have someone else write) a longer version on the website, with more multimedia, and with plenty of links to external sources, explainers, other scientific papers, bloggers who explained it better?

How to rethink the Space Restrictions

Once upon a time, buying a newspaper or magazine was an act of getting informed. What was printed in it was what information you got for the day.
Today, a newspaper is a collection of invitations to the paper’s website, a collection of “hooks” that are supposed to motivate the readers to come to the website. Different stories will hook different readers, but they will all end up online, on the site (where they may start clicking/looking around). Why? To see more!!!!

What a disappointment when they come to the website to see more…only to find exactly the same two inches they just read on paper!!!! Where is “more”? Where is the detailed explainer, the context, the useful links? Not there? What a disappointment! But the reader is still interested and will Google the keywords and will leave your site and end up on a wonderfully rich and informative science blog instead, never to come back to you and your poor offering.
Public radio folks – both NPR and PRI – have long ago realized this. Have you noticed how every program, and often every story, ends up with an invitation to the listeners to come to the website to see more – images, videos, documents, interactive games, discussion forums, even places where the audience can ask questions (and get answers) of the people they just heard as guests on the radio? Radio understands that their “space” (time) is limited and heavily rationed (seconds instead of inches) and they use their programing as a collection of hooks produced specifically to pique interest in people, as lures for the audience to go to the website to ‘see more’. And there is a lot of that “more” on their sites for people to keep coming back.

Very few newspapers have realized this yet – some have, but their online offerings are still not rich enough to be truly effective. Let’s hope they start doing more of that if they want to retain the trust and reputation of their brand names and to retain the audience that is loyal to their brand names.

ScienceOnline2010 – interview with Travis Saunders

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Travis Saunders (Twitter), my SciBling from the Obesity Panacea blog to answer a few questions.
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 (scientific) background?
I am a PhD student in Exercise Physiology at the Children’s Hospital of Eastern Ontario Research Institute in Ottawa, Ontario, Canada. My undergrad was in Kinesiology (aka Physical Education) at the University of Calgary, and my Masters was in Exercise Physiology at Queen’s University.
Tell us a little more about your career trajectory so far: interesting projects past and present?
Travis Saunders pic.jpgMy research focuses on the inter-relationships between obesity, physical activity, and chronic disease risk. For example, I have been involved with studies examining the relationship between different fat depots and health risk (abdominal fat is very bad, but leg fat can actually be protective in some situations), as well as studies examining the benefits of exercise with or without weight-loss (your lipid profile and insulin sensitivity almost always improve in response to exercise, while inflammatory markers seem to improve only in response to weight loss). I’ve just begun my PhD, which is looking at the relationship between sedentary time (e.g. sitting) and health risk. For example, if you run for an hour every morning but then spend the next 7 hours sitting in front of a computer, is your metabolic health going to be better or worse than someone who spends all day on their feet but rarely performs vigorous exercise? No one knows just yet, but it’s a very interesting area of study with important public health implications.
What is taking up the most of your time and passion these days? What are your goals?
Right now most of my time is being spent developing my PhD project, as well as (hopefully) getting a few side projects published. I’m fortunate to really enjoy my area of research, as well as the people I work with, so it’s a pretty fun way to spend my days. My short-term goal is to do research that is both interesting to me personally and that has a positive influence on the health of the population. I don’t have any specific long-term goals aside from finishing my PhD, but I know that I want to be involved with both research and science communication in whatever I do next.
What aspect of science communication and/or particular use of the Web in science interests you the most?
It is absolutely critical that researchers share their findings with the general public, rather than just other colleagues within their research area. I think it’s especially important for those of us performing tax-payer funded research – if the public is paying for our research it only makes sense that we should do everything we can to keep them informed of our results. If the public is better informed they can make better health decisions, but they are also in a better position to understand the value of our research – a clear win-win! For a young researcher like myself, the Web is by far the easiest way to communicate with the public about my area of research.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
Blogging has had a very positive impact on my work to date. Writing a blog is almost like doing 2 or 3 Journal Club presentations every week! It has forced me to stay up-to-date on the latest studies in my field of research, and has also helped me to develop my understanding of a number of issues (it’s one thing to skim through a paper, but it’s another thing entirely to write an intelligible blog post about it!) Blogging has also been tremendously helpful in preparing for conferences – responding to comments and questions online is very similar to responding to questions following a presentation (but in a much less stressful environment). As a result, it has made me a much more confident writer and speaker, which has direct benefits in my day-to-day work. And finally, blogging has been a very effective means of spreading the word about my own area of research, which is the whole reason I got into blogging in the first place!
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 first discovered science blogs (and ScienceBlogs) in SEED magazine. My girlfriend bought me the magazine on a whim and I absolutely loved it, and when I saw an ad for ScienceBlogs I knew it was something that I had to check out. Around the same time my labmate Peter and I stumbled upon the blogs of Drs Arya Sharma and Yoni Freedhoff, two physicians who specialize in the treatment of obesity. That was when we realized that science blogging was something we wanted to get involved with.
For me personally, the coolest part of ScienceOnline2010 was meeting the bloggers that I have been following for the past few years. This includes people like yourself, Ed Yong, Scicurious, the gang from Science Based Medicine, and Dave Munger to name just a few. It was especially nice to meet Dave as he’s not only a phenomenal writer, but also because he has done such great work promoting peer-reviewed research via ResearchBlogging.org.
What was the best aspect of ScienceOnline2010 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?
The best part for me was meeting all of the other participants. There were some incredibly talented science-communicators in attendance, and it was a lot of fun to be able to learn from them. Rebecca Skloot’s session on pitching story ideas was especially useful, and gave me a much better understanding of how to frame a story in a way that appeals to journalists, which is an extremely important skill as a researcher.
This year’s conference featured some top-notch science-communicators (Michael Specter, Ed Yong, Rebecca Skloot, Carl Zimmer, etc); I’d love to see next year’s conference bring in a few more top-notch researchers – maybe a Nobel Prize winner or prominent researcher like Brian Greene or Freeman Dyson. This year’s conference helped me learn a lot about science communication from the perspective of journalists and bloggers, but I feel it would be extremely useful to hear what these top researchers could add to the discussion.
Thanks again for all the hard work that you and Anton put into the conference, it was an amazing experience!
It was so nice to meet you in person and thank you for the interview. I hope to see you again next January.

Science Café Raleigh – The Human-Animal Bond

Hi Café Friends,
Our June Science Café (description below) will be held on Tuesday 6/15 at the Irregardless Café on Morgan Street. Our café speaker for the evening will be Dr. Dianne Dunning from the NCSU School of Veterinary Medicine. Join us for a thought provoking discussion with Dr. Dunning about the relationships humans have with animals in our increasingly crowded world.
The Human-Animal Bond
Tuesday June 15, 2010
Time: 6:30 – 8:30 pm with discussions beginning at 7:00 followed by Q&A
Location: The Irregardless Café, 901 W. Morgan Street, Raleigh 833-8898
Animals touch our daily lives — from the pets we keep, to the food we eat, to the health care advances we enjoy. Current animal welfare concerns include pet overpopulation, rescue and care of animals in disasters, treatment of food animals, biomedical research involving animals, and the affects of global urbanization and environmental change on wildlife. Our evolving human-animal bond and the mandate to be good stewards of animal welfare are at the heart of these concerns. Join our discussion about how the integration of veterinary medicine and animal science, as well as ethics and public policy, can dictate how successfully these concerns are addressed, and how the diverse needs of humans and animals are met on a local and global scale.
About the Speaker
Dr. Dianne Dunning is a clinical associate professor and the director of the Animal Welfare, Ethics and Public Policy Program (AWEPP) at the NC State College of Veterinary Medicine. Through professional education, public service, research and public policy development, AWEPP seeks to explore and address issues including pet abandonment, animal abuse and fighting, companion animal loss and grief, and the link between animal health and human well being.
Please RSVP (Katey Ahmann: kateyDOTahmannATncdenrDOTgov ) if you are able to come – As always, I will be communicating with the restaurant so that we can have a good set-up for our group.
Looking forward to seeing eveyone on the 15th – hope you can come.

New and Exciting in PLoS this week

Distorted Views of Biodiversity: Spatial and Temporal Bias in Species Occurrence Data:

Historical as well as current data on species distributions are needed to track changes in biodiversity. Species distribution data are found in a variety of sources but it is likely that they include different biases towards certain time periods or places. By collating a large historical database of ~170,000 records of species in the avian order Galliformes, dating back over two centuries and covering Europe and Asia, we investigate patterns of spatial and temporal bias in five sources of species distribution data: museum collections, scientific literature, ringing records, ornithological atlases, and website reports from “citizen scientists.” Museum data were found to provide the most comprehensive historical coverage of species’ ranges but often proved extremely time-intensive to collect. Literature records have increased in their number and coverage through time, whereas ringing, atlas, and website data are almost exclusively restricted to the last few decades. Geographically, our data were biased towards Western Europe and Southeast Asia. Museums were the only data source to provide reasonably even spatial coverage across the entire study region. In the last three decades, literature data have become increasingly focussed towards threatened species and protected areas, and currently no source is providing reliable baseline information–a role once filled by museum collections. As well as securing historical data for the future and making it available for users, the sampling biases will need to be understood and addressed if we are to obtain a true picture of biodiversity change.

Secondary Prevention of Suicide:

Suicide prevention can be primary, secondary, or tertiary. Primary suicide prevention aims to reduce the number of new cases of suicide in the general population [5]. Secondary suicide prevention aims to decrease the likelihood of a suicide attempt in high-risk patients [5]. Tertiary suicide prevention occurs in response to completed suicides and attempts to diminish suicide contagion (clusters of suicides in a geographical area that occur predominantly among teenagers and young adults) and copy-cat suicides [5],[6].
Secondary suicide prevention is particularly important but not always given the attention that it deserves, in part because research into secondary prevention is only just starting to be applied to clinical practice. In this article, we discuss recent research on the evaluation of suicidal risk and on different kinds of secondary suicide prevention interventions that aim to reduce that risk. We also indicate how these interventions are currently being applied and what additional research is needed.

Multi-Way Multi-Group Segregation and Diversity Indices:

How can we compute a segregation or diversity index from a three-way or multi-way contingency table, where each variable can take on an arbitrary finite number of values and where the index takes values between zero and one? Previous methods only exist for two-way contingency tables or dichotomous variables. A prototypical three-way case is the segregation index of a set of industries or departments given multiple explanatory variables of both sex and race. This can be further extended to other variables, such as disability, number of years of education, and former military service. We extend existing segregation indices based on Euclidean distance (square of coefficient of variation) and Boltzmann/Shannon/Theil index from two-way to multi-way contingency tables by including multiple summations. We provide several biological applications, such as indices for age polyethism and linkage disequilibrium. We also provide a new heuristic conceptualization of entropy-based indices. Higher order association measures are often independent of lower order ones, hence an overall segregation or diversity index should be the arithmetic mean of the normalized association measures at all orders. These methods are applicable when individuals self-identify as multiple races or even multiple sexes and when individuals work part-time in multiple industries. The policy implications of this work are enormous, allowing people to rigorously test whether employment or biological diversity has changed.

Whaling – Politics, Science & Ethics

The new forum at PRI World Science:

Listen to a story by reporter Eric Niiler, followed by our interview with Stephen Palumbi.
Our guest in the Science Forum is marine biologist Stephen Palumbi of Stanford University. He uses genetics to study whale populations.
The International Whaling Commission is considering legalizing commercial whaling by some countries, but at a very limited scale. Palumbi says that the current proposal would fail to protect endangered whale species.
You can ask Palumbi your own questions. Join the conversation. It’s just to the right.
* Do you think all whaling should be banned? Why?
* What role can lay citizens play in conserving whales?
* How can modern genetic techniques be used to crack down on whale smuggling?

ScienceOnline2010 – interview with Cassie Rodenberg

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Cassie Rodenberg to answer a few questions.
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 (scientific) background?
Cassie Rodenberg pic2.jpgI’m a Charleston, SC native that now resides in NYC — a complete Northern convert that carries an appreciation for Southern plantations and shrimp ‘n grits. As a kid I slogged through marshes to erect an osprey perch, played slippery ‘jelly ball’ (jellyfish) hockey on a shrimp boat and floated an ATV across a river, only now realizing how much science I was experiencing. The physics of ATV floating? The surprising number of jelly balls hoisted aboard a boat when hunting for shrimp? The torturous plotting of perch placement in attracting birds of prey? Science is everywhere, why hadn’t I noticed?
I’m shamelessly effervescent about science now, dying to share a cool science factoid or an interesting study, which somehow bubble out despite my best efforts to stem them! I think people care about science more than we think they do; science communicators just need to find out what intrigues them– like ATVs or jellyfish hockey games. Enthusiasm and passion are contagious, too. If we’re truly excited, others will be as well. We all need to find the inner kid that’s fascinated by the world around us, the one that shouts, “oo, cool!” before trying to reach the public.
I studied chemistry during college, finding it the most beautifully simple and elegant of all the sciences. Under an NIH grant, I conducted inorganic chemistry research — single molecule spectroscopy — on the Amyloid-Beta peptide associated with Alzheimer’s, looking at different conditions that stimulate growth of the earliest cytotoxic stages of peptide and thus spur the disease’s formation. And my 11-year-old brother would be horrified if I didn’t mention the coolest part: I worked with a laser in the dark.
Tell us a little more about your career trajectory so far: interesting projects past and present?
Gosh, it certainly is an interesting trajectory…after my lab days I wanted to investigate the public’s perception of science, how people thought about science on a daily basis. Actually, I was so intrigued, I later published psychology research on the subject. If we’re making careers out of reaching people and teaching, we better understand where these people come from and how they think.
And so, I worked at a local science museum, teaching science in big public programs — chemistry demonstrations, reptile shows (yes, I held everything from boas to Madagascar hissing roaches to tarantulas)… even walked around in a toga as the Lady of Pompeii to guide in ancient medicinal practices. Besides learning fascinating things myself (iguanas have a third light-sensing eye on the tops of their heads, my long curly hair could stand on end with enough static electricity power..), I learned quickly how to speak across age barriers, from the three-year-old to her great-grandmother to her bored aunt with a Blackberry.
After, I moved to NYC and took science journalism graduate courses at NYU before becoming an in-house contributor at Popular Mechanics and a writer for the weekly science section of the Charlotte Observer.
Now I’m starting at Discovery as an associate web producer, working mainly with planetgreen.com, a environmental and futuristic tech initiative.
What is taking up the most of your time and passion these days? What are your goals?
Cassie pic.jpgThe geek side of me loves production and organization. Though I like writing, I don’t feel married to my byline — the important thing to me is contributing to something meaningful. I hope to do more entrepreneurial work with both science- and non-science-based efforts, hopefully working with idea geniuses to launch new projects. Of course, I’d expect that whatever I delve in will have some scientific element to it, but hybridizing science with other subjects makes it more tangible to readers. We should always be reaching and trying new things… I could never imagine myself without a side project bubbling in the recesses of my mind.
You used to be involved with Scienceline until recently. Can you tell us a little bit more about the project, what was your role there, and what were your experiences while working there? Was it a useful jumping board for your career?
Scienceline is a project of NYU’s graduate science journalism program — all students contributed to running the website and producing content, a mini-newsroom of sorts. It’s a bit like training wheels on a bike: it’s important to get newsroom experience, even working with fellow students as editors, before getting started in the real world of journalism. Though I think it is useful to an extent, especially for giving prospective employers links to clips, I encourage all students to go for internships first and foremost. I’ve always learned most by jumping headlong into a field.
What aspect of science communication and/or particular use of the Web in science interests you the most?
The web provides science communicators a wonderful opportunity for collaboration. Once upon a time, in a small town in South Carolina, I didn’t know any science writers, didn’t know who to go to for advice and inspiration. The web has transformed this, and that struggle isn’t true anymore, as we have genius at our fingertips at just a tweet away. We can craft ideas, bounce them off one another and form relationships. Even further, we can debunk bad science, pass along source recommendations and generate excitement on an issue.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
I started out blogging but lost steam fairly quickly, realizing that Twitter was a much better outlet for my exuberance that a blog post because, honestly, I want to talk about science news constantly… but don’t usually have time to blog about it. On Twitter, I can post the gist of my opinion and ask others for theirs in return — much more effective and efficient than waiting around for comments on WordPress. I can feel the hum of my network around my tweets, much more vibrant than a blog. Twitter is inordinately positive in what I do — knowing what the public thinks should be as, if not more so, important to a journalist as writing a piece, and Twitter magnifies the vitality of readers.
Just after ScienceOnline2010, I highlighted an online event in which you played a central role, that hints at how some aspects of the new journalistic ecosystem – scientist-journalist collaboration – may work. What are your thoughts, in light of this event, on the ways the science journalistic ecosystem is changing?
I think scientists and journalists are finally understanding how much they need one another to effectively change the way science news is disseminated. Science journalism should never have been a fragmented system, it should be a constant conversation and relationship between two different sorts of people united by a single goal. Honest and important news comes from general concern and idea generation — the best ideas come from different vantage points. In the future, I imagine scientists and journalists brainstorming and mingling over drinks, public interest forefront. I’ve already mingled on Twitter — the web only enhances the science/journalist cocktail hour.
What was the best aspect of ScienceOnline2010 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?
It staggered me to think beyond web and print communication and on towards TV, entertainment and citizen journalism projects. It’s invigorating to realize what an effort there is to mesh good science with the public realm and gives me hope that scientific accuracy may not be so far away, that scientists won’t always be portrayed in movies as ‘mad’ and that everyone can do small science projects at home for the benefit of a larger goal.
It was so nice to meet you in person and thank you for the interview. Looking forward to meeting you again soon in NYC and I hope to see you here again next January.

ScienceOnline2010 – interview with Fenella Saunders

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Fenella Saunders from The American Scientist to answer a few questions.
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 (scientific) background?
Fenalla Saunders pic.jpgI was born in England, raised in New York City, did my undergraduate at Duke University in North Carolina, went back to New York for 10 years, then came back to NC five years ago. I have a master’s degree in animal behavior from Hunter College of the City University of New York, where I did my thesis on the interactions of proboscis monkeys in captivity. My undergraduate degree is in computer science with a minor in Japanese, although I chose my major with the concept of going into science journalism.
While I was at college I discussed the education I would need with a number of science journalists, all of whom told me that an education in science, with outside projects to get journalism experience, was the best way to go. (I am from the era just before when it became pretty much standard for science writers to go to an MA program for science journalism.) A computer science major allowed me to study a broad range of sciences and technology, and it also gave me a backup plan in case journalism didn’t work out. At school I wrote for any venue I could get into (and I was lucky that in addition to a regular school paper with a health/medicine section, Duke had both a student-run science and a technology magazine), and in my senior year I wrote a couple of small pieces freelance for Popular Mechanics.
Tell us a little more about your career trajectory so far: interesting projects past and present?
My career started when I landed an internship at Discover Magazine, then got hired on. It was largely a matter of luck and timing: They had a lot of biology people and needed someone with a technology background. I stayed at Discover for about eight years, and ended up also being the online editor toward the end of that time. There were a ton of great moments at that job, but I would have to say my favorite one was when they allowed me to start writing about a different, new robot in each month’s news section. It was a series that lasted 2-3 years, and I never ran out of new robotics research to write about. During that time I freelanced a little, most notably as a co-author for a Time-Life book called “Space 2100.” I left Discover to work on publications for NYU School of Medicine for about two years, which was a very different experience. Probably the best part of that job was learning all about really high-powered MRI machines. For the past five years I’ve been at American Scientist, where I am now a senior editor. It is both fascinating and a challenge working with different scientists each issue, trying to get them to explain their own work for a general audience. I couldn’t even begin to pick a favorite from all of the articles I’ve helped bring to print–it could be anything from Champagne bubbles to snow flakes to honeybee nest relocation.
What is taking up the most of your time and passion these days? What are your goals?
American Scientist is published every two months, so we always confront the problem of remaining timely. We want to find more ways to keep in contact with our readers between issues. We recently relaunched our Web site, which allowed us to better keep up with technology in a few ways. We’re now able to embed video with the online versions of articles. We now also post podcasts of our lunch-speaker series. I am excited that I have been chosen as a fellow to attend on of the Knight Digital Media Center’s multimedia workshops, where I’ll learn more about how to edit audio, video and maybe program some Flash animation. I am hoping that after I attend that workshop, I will be better equipped to have us do more multimedia for the magazine online.
What aspect of science communication and/or particular use of the Web in science interests you the most?
The immediacy of the Web still is its biggest advantage in my mind. Something can be posted for all of the world to see within minutes, and if you are looking for information on a specific topic, a quick search will pull up enough reading to last hours. It’s a very democratic platform, as anyone can post on it, but that makes it all the more important to make sure that sources are reputable and verifiable–I am pretty sure that we all rely too much on the truthfulness of Wikipedia these days. I am also hopeful that the Web can make information, about science or anything, more accessible to people who, say, don’t have the luxury of going to college, or find themselves in a position of having to learn about something new that they never thought about doing.
That being said, I am still unsure of how the print vs. online debate is going to shake out. There is something to be said for picking up a whole magazine, not just a specific article you were looking for. It is broadening to be exposed to topics you might not have even realized existed. People are busy, so in some ways it’s faster just to pick up a print copy rather than have to search and dig online. Perhaps platforms such as the iPad will change all this. But I know that, when I have the time, just browsing through publications in the library is the best way for me to get new ideas.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
It’s fairly bizarre for a publication not to use all social-media platforms possible these days. We send out a daily and a weekly conglomeration of science news, and we tweet about these entries daily as well. We also use twitter to talk about what’s in our latest issue, and we tweet about any news that relates to a past story that we have done. We have groups on Facebook and LinkedIn. We don’t have a set blog yet, although we are working on it, but our Computing Science columnist, Brian Hayes, has a regular one at bit-player.org.
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?
Carl Zimmer is a former colleague of mine at Discover magazine, and he was an early entry into the blogosphere, so his was probably the first blog that I followed. I was happy to meet Ed Yong at the conference, and I follow his blog “Not Exactly Rocket Science.” I’ve also been following Rebecca Skloot’s blog about her book “The Immortal Life of Henrietta Lacks.”
What was the best aspect of ScienceOnline2010 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?
I really liked the fact that there were kids at the conference. Kids often are not brought into the dialogue when discussing science, particularly science journalism. Sometimes they are the target audience, but they are rarely part of the process. For a few years we did a mentoring program with a local middle school where we’d have kids come in for a week, but they’d rotate, so I’d get each student for only one day. I challenged them that they would write a whole science news story by the end of the day, and they all looked at me like I was crazy, but they all did it. Children can do amazing things if given the opportunity, and can provide unique insight. I found it particularly enlightening that the young students at ScienceOnline 2010 thought that Twitter was an adult thing–they saw no real use for it in their lives, preferring more interactive platforms such as Facebook.
I can’t say my usual “It was so nice to meet you in person” because I see you often, but certainly thank you for the interview. I hope to see you again soon.

Scott Huler – ‘On The Grid’ at Quail Ridge Books

huler 003.JPGAs I alerted you before, last night Scott Huler (blog, Twitter, SIT interview) did a reading from his latest book On The Grid (amazon.com) at the Quail Ridge Books in Raleigh.
The store was packed. The store sold out all the books before Scott was even done talking. The C-Span Book TV crew was there filming so the event will be on TV some day soon. Scott was also, earlier yesterday, on WUNC’s The State Of Things (the podcast will soon be online here) and the day before that he was on KERA’s Think with Krys Boyd (download MP3 podcast by clicking here).
Scott’s energy and enthusiasm are infectuos. He held the audience captive and often laughing. The questions at the end were smart and his answers perfectly on target. But most importantly, we all learned a lot last night. I think of myself as a reasonably curious and informed person, and I have visited at least a couple of infrastructure plants, but almost every anecdote and every little tidbit of information were new to me. Scott’s point – that we don’t know almost anything about infrastructure – was thus proven to me.
What Scott realized during the two years of research for the book is that people in charge of infrastructure know what they are doing. When something doesn’t work well, or the system is not as up-to-date as it could be, it is not due to incompetence or ignorance, but because there is a lack of two essential ingredients: money and political will. These two factors, in turn, become available to the engineers to build and upgrade the systems, only if people are persuaded to act. And people are persuaded to act in two ways: if it becomes too costly, or if it becomes too painful to continue with the old way of doing things. It is also easier to build brand new systems for new services than it is to replace old systems that work ‘well enough’ with more more modern ways of providing the same service.
huler 002.JPGThere are people who advocate for moving “off the grid” and living a self-sufficient existence. But, as Scott discovered, they are fooling themselves. Both the process of moving off the grid and the subsequent life off the grid are still heavily dependent on the grid, on various infrastructure systems that make such a move and such a life possible, at least in the developed world.
What is really astonishing is how well the systems work, even in USA which has fallen way behind the rest of the developed world. We are taking it for granted that the systems always work, that water and electricity and phone and sewers and garbage collection and public transportation always work. We get angry on those rare occasions when a system temporarily fails. We are, for the most part, unprepared and untrained to provide some of the services ourselves in times of outages, or to continue with normal life and work when a service fails. And we are certainly not teaching our kids the necessary skills – I can chop up wood and start a wood stove, I can use an oil heater, I know how to slaughter and render a pig, how to get water out of a well, dig a ditch, and many other skills I learned as a child (and working around horses) – yet I am not teaching any of that to my own kids. They see it as irrelevant to the modern world and they have a point – chance they will ever need to employ such skills is negligible.
grid_cover.jpgI got the book last night and am about to start reading it – very eagerly so. Scott started with his house in Raleigh and traced all the wires and cables and pipes going in and out of the house to see where they led. He compared what he learned in Raleigh and its various infrastructure experts and officials, to the equivalent services in other geographical places, and traced them back in history. I can’t wait to read the synthesis of all that research. I hope you will read it, too.

Serious Gaming at Sigma Xi

Last week I went to this season’s last American Scientist pizza lunch at Sigma Xi featuring Phaedra Boinodiris (Twitter, blog), Serious Games Product Manager at IBM.
I first saw Phaedra Boinodiris speak as the opening speaker at TEDxRTP (my review) back in March, but this was a different kind of talk, geared more towards scientists and science communicators.
I remember playing Pong when it first came out. I remember spending many hours back in 1980 or so playing The Hobbit on Sinclair ZX Spectrum. And I played many games at arcades (still not knowing which games started out as arcade games adapted to computers and which the other way round). Then I quit playing games for a couple of decades until my kids were ready for them. I loved Zoombinis – an amazing game of logic and a brilliant preparation for taking IQ tests! I loved Richard Scarry’s Busytown – the one and only game I know about infrastructure, where players build stuff and deliver it to others for the good of the town – from baking bread to paving roads – learning along the way how those things are done.
And sure, Phaedra Boinodiris started with a slide depicting Pong (to the chuckle of the audience) but soon got into the real stuff – the serious gaming and the story of how she got involved in developing such games, as well as about studies of gaming and how different kinds of games help develop different real-work skills, from eye-hand coordination to leadership to cooperation. Her first game – INNOV8 – was developed as a prototype, a proof of concept, in only three months and instantly became a huge hit. It is used by businesses and business schools around the world to teach Business Process Management. It is essentially a first person shooter game (without guns) in which the player is brought as an outside consultant into a company where s/he has to figure out the flow, the bottlenecks, etc. (including by interviewing employees, as well as data-sheets) and experiment in making it more efficient. The 2.0 version came soon after, adding such problems as traffic, customer service and supply chains.

The next game, recently announced and coming out in October 2010, will be a Sim-City-like serious game CityOne, designed to help city planners, town councils, citizens, and engineers plan better, more efficient infrastructure for their cities. Put in your city’s specs and start building new infrastructure, see how much it will cost, see what problems will arise, see what solutions are available – probably something you could not have thought of yourself and may be surprised.
As I am currently reading ‘On The Grid’ it occured to me that the developers of CityOne should read that book, and that Scott Huler should be given a test-run of the game, perhaps for him to review for Charlotte Observer and Raleigh News&Observer and the local NPR station. And for Science In The Triangle, of course.

‘On The Grid’ by Scott Huler at Quail Ridge Books

Last night I went to the book reading of “On The Grid” by Scott Huler at Quail Ridge Books in Raleigh. It was a great event. I wrote a more detailed summary over on Science In The Triangle.

ScienceOnline2010 – interview with Jeremy Yoder

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Jeremy Yoder from University of Idaho and the Denim and Tweed blog to answer a few questions. Jeremy came to ScienceOnline2010 as one of the two winners of the NESCent blogging contest.
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 (scientific) background?
Jeremy Yoder pic.jpgHello, and many thanks for having me! I’m not sure how best to start this, so I’ll just go from the beginning:
I grew up very Mennonite in rural Pennsylvania (no, there were no buggies involved). I’m more-or-less an agnostic now, but my thinking is still strongly influenced by Mennonite values of peacemaking, simplicity, and independent inquiry.
I had my first taste of field biology in my senior year of high school, when one of my science teachers led the class through a forest survey in a woodlot adjacent to the campus. By cataloguing the trees according to their age class and species, we were able to deduce how mature the woodland was, and what it might look like in another hundred years. It opened up this vision of species jostling against each other, accommodating as well as competing to shape the landscape right outside my front door, and it seemed like a pretty cool thing to do for a living.
Tell us a little more about your career trajectory so far: interesting projects past and present?
From high school on I did my best to arrange to spend time outdoors. I majored in environmental science as an undergraduate, and then spent a year interning with the Western Pennsylvania Conservancy, working on plant community ecology among other projects. When I started to think about graduate school, I knew I wanted to study coevolution — the ways in which interacting species shape each other’s evolutionary history — and I was lucky enough to connect with Olle Pellmyr, who was looking for a new graduate student to work on his current study of Joshua trees and the moths that pollinate them.
Joshua tree populations are exclusively pollinated by one or the other of two different species of yucca moths. It turns out that trees from populations with different pollinators look pretty different themselves, and we now have good reason to think that the moths’ preferences for their “native” type of Joshua tree determines how often the two tree types can interbreed. A big part of my dissertation work is to use DNA sampling from Joshua trees across the whole Mojave desert to estimate how completely the two types of Joshua tree are isolated, and how much coevolution with the moths is responsible for the differences we see in the two types of tree. Before I started grad school, I’d never seen a North American desert — now I’ve been to just about every place Joshua trees grow, from the south rim of the Grand Canyon to the outer suburbs of Los Angeles and (I kid you not) just outside of Area 51.
Joshua Trees pic.jpg
What is taking up the most of your time and passion these days? What are your goals?
My dissertation is far and away my biggest preoccupation, you won’t be surprised to hear. I’ve just had a couple of projects accepted for publication — a literature review and an analysis that reconstructs some characteristics of the ancestors of yucca moths. I’m (hopefully) nearly done with a mathematical model that compares how different kinds of coevolutionary interactions affect the species involved, and I’m heavily occupied with the Joshua tree DNA analysis right now. My plan is to complete my doctorate by about this time next year, and I’m starting to think about possible postdoctoral work (hint, hint!).
I’m also keeping up with writing on Denim and Tweed for the time being, and I’m thinking about running what will be my second marathon sometime this fall. Hopefully, I’ll find some time to get out and enjoy the wilderness out here in the Pacific Northwest this summer, too, since this might be the last year I spend within a day’s drive of both Olympic and Glacier National Parks.
What aspect of science communication and/or particular use of the Web in science interests you the most?
Most academic biologists spend time teaching in addition to their research, and I really believe that telling the general public about my work is a logical extension of that principle — that being a scientist means communicating what you learn to others, not just accumulating knowledge to satisfy your own curiosity. The Web is a great venue for that, thanks to user-friendly blog hosting services and networks like Research Blogging and the Nature Blog Network that connect interested readers to my site. I now list D&T as a “broader impact” on all my grant applications.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
I try to treat Denim and Tweed as an exercise in writing about science for a general audience — so it has that value for me even if no one reads it. In that sense, it’s a little like a one-man journal club, in which I sit down every week and read one paper carefully enough to explain it to someone else in about 700 words.
The blog is pretty heavily linked into my online social network as well — I have a public account on Twitter that I use regularly, and a FriendFeed profile that ties together the blog, my Flickr account, and my Facebook profile. And I interact with family, personal acquaintances, colleagues, and readers of D&T across all those platforms — over my last field trip, I’d post photos from Flickr to the blog, and have folks comment about them on my Facebook wall. It’s not very tidy, but every one of those networks seems to reach a slightly different set of people, so I guess I’m thoroughly enmeshed.
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’ve been reading science blogs since long before it occurred to me to start writing on my own — I don’t remember exactly how I got started, but my first contact was probably when someone sent me a snarky link from Pharyngula. I think I probably didn’t have a sense of the full scope of the science blogosphere before I found Research Blogging, though.
Through RB, I’ve found great sites like The EEB & flow, Conservation Maven, and Open Source Paleontologist, and even occasionally exchanged thoughts in the comments or via back-and-forth posts. Research Blogging is really a fantastic way to get started in writing about science on your own blog, both because it’s easy to add your posts to a feed lots of other science bloggers read and because it helps you find other people writing about the sort of science that interests you.
And then, after I’d been involved in RB for more than a year, I was lucky enough to be able to attend ScienceOnline 2010, and meet in person a number of folks I really only knew as text on the screen — and, yes, add a number of links to my RSS list, including Observations of a Nerd. I think I picked up far more Twitter feeds than blogs at ScienceOnline, though — so much of the conference conversation occurred on Twitter that it was basically unavoidable. And now I probably get more of my online science news via folks I’m following on Twitter than even through the RSS feeds I have bookmarked in Firefox.
What was the best aspect of ScienceOnline2010 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?
I think the biggest benefit I took from ScienceOnline2010 was a better sense of where I fit in the world of online science communication, in my role as a scientist with a blog. I saw some great models of how to draw the public into ongoing scientific work using online tools, and even how to engage the public in the actual science. I also saw some great sessions that addressed interactions among different groups of people involved in science communication — working scientists, educators, and science journalists. It was a really fun weekend all around, and it gave me a lot to think about as I work towards the (still pretty distant!) day when I’m ready to set up my own lab and research program.
It was so nice to meet you in person and thank you for the interview. I hope to see you again next January.

New and Exciting in PLoS ONE

Another amazing serving of Wednesday sciencey goodness with 40 new articles in PLoS ONE today. As always, you should rate the articles, post notes and comments and send trackbacks when you blog about the papers. You can now also easily place articles on various social services (CiteULike, Mendeley, Connotea, Stumbleupon, Facebook and Digg) with just one click. Here are my own picks for the week – you go and look for your own favourites:
A New Pterosaur (Pterodactyloidea: Azhdarchidae) from the Upper Cretaceous of Morocco:

The Kem Kem beds in South Eastern Morocco contain a rich early Upper (or possibly late Lower) Cretaceous vertebrate assemblage. Fragmentary remains, predominantly teeth and jaw tips, represent several kinds of pterosaur although only one species, the ornithocheirid Coloborhynchus moroccensis, has been named. Here, we describe a new azhdarchid pterosaur, Alanqa saharica nov. gen. nov. sp., based on an almost complete well preserved mandibular symphysis from Aferdou N’Chaft. We assign additional fragmentary jaw remains, some of which have been tentatively identified as azhdarchid and pteranodontid, to this new taxon which is distinguished from other azhdarchids by a remarkably straight, elongate, lance-shaped mandibular symphysis that bears a pronounced dorsal eminence near the posterior end of its dorsal (occlusal) surface. Most remains, including the holotype, represent individuals of approximately three to four meters in wingspan, but a fragment of a large cervical vertebra, that probably also belongs to A. saharica, suggests that wingspans of six meters were achieved in this species. The Kem Kem beds have yielded the most diverse pterosaur assemblage yet reported from Africa and provide the first clear evidence for the presence of azhdarchids in Gondwana at the start of the Late Cretaceous. This, the relatively large size achieved by Alanqa, and the additional evidence of variable jaw morphology in azhdarchids provided by this taxon, indicates a longer and more complex history for this clade than previously suspected.

Large-Range Movements of Neotropical Orchid Bees Observed via Radio Telemetry:

Neotropical orchid bees (Euglossini) are often cited as classic examples of trapline-foragers with potentially extensive foraging ranges. If long-distance movements are habitual, rare plants in widely scattered locations may benefit from euglossine pollination services. Here we report the first successful use of micro radio telemetry to track the movement of an insect pollinator in a complex and forested environment. Our results indicate that individual male orchid bees (Exaerete frontalis) habitually use large rainforest areas (at least 42-115 ha) on a daily basis. Aerial telemetry located individuals up to 5 km away from their core areas, and bees were often stationary, for variable periods, between flights to successive localities. These data suggest a higher degree of site fidelity than what may be expected in a free living male bee, and has implications for our understanding of biological activity patterns and the evolution of forest pollinators.

Helper Response to Experimentally Manipulated Predation Risk in the Cooperatively Breeding Cichlid Neolamprologus pulcher:

We manipulated predation risk in a field experiment with the cooperatively breeding cichlid Neolamprologus pulcher by releasing no predator, a medium- or a large-sized fish predator inside underwater cages enclosing two to three natural groups. We assessed whether helpers changed their helping behaviour, and whether within-group conflict changed, depending on these treatments, testing three hypotheses: ‘pay-to-stay’ PS, ‘risk avoidance’ RA, or (future) reproductive benefits RB. We also assessed whether helper food intake was reduced under risk, because this might reduce investments in other behaviours to save energy. Medium and large helpers fed less under predation risk. Despite this effect helpers invested more in territory defence, but not territory maintenance, under the risk of predation (supporting PS). Experimentally covering only the breeding shelter with sand induced more helper digging under predation risk compared to the control treatment (supporting PS). Aggression towards the introduced predator did not differ between the two predator treatments and increased with group member size and group size (supporting PS and RA). Large helpers increased their help ratio (helping effort/breeder aggression received, ‘punishment’ by the dominant pair in the group) in the predation treatments compared to the control treatment, suggesting they were more willing to PS. Medium helpers did not show such effects. Large helpers also showed a higher submission ratio (submission/ breeder aggression received) in all treatments, compared to the medium helpers (supporting PS). We conclude that predation risk reduces helper food intake, but despite this effect, helpers were more willing to support the breeders, supporting PS. Effects of breeder punishment suggests that PS might be more important for large compared to the medium helpers. Evidence for RA was also detected. Finally, the results were inconsistent with RB.

The Promise and Perils of Pre-Publication Review: A Multi-Agent Simulation of Biomedical Discovery Under Varying Levels of Review Stringency:

The Internet has enabled profound changes in the way science is performed, especially in scientific communications. Among the most important of these changes is the possibility of new models for pre-publication review, ranging from the current, relatively strict peer-review model, to entirely unreviewed, instant self-publication. Different models may affect scientific progress by altering both the quality and quantity of papers available to the research community. To test how models affect the community, I used a multi-agent simulation of treatment selection and outcome in a patient population to examine how various levels of pre-publication review might affect the rate of scientific progress. I identified a “sweet spot” between the points of very limited and very strict requirements for pre-publication review. The model also produced a u-shaped curve where very limited review requirement was slightly superior to a moderate level of requirement, but not as large as the aforementioned sweet spot. This unexpected phenomenon appears to result from the community taking longer to discover the correct treatment with more strict pre-publication review. In the parameter regimens I explored, both completely unreviewed and very strictly reviewed scientific communication seems likely to hinder scientific progress. Much more investigation is warranted. Multi-agent simulations can help to shed light on complex questions of scientific communication and exhibit interesting, unexpected behaviors.

Recurrent, Robust and Scalable Patterns Underlie Human Approach and Avoidance:

Approach and avoidance behavior provide a means for assessing the rewarding or aversive value of stimuli, and can be quantified by a keypress procedure whereby subjects work to increase (approach), decrease (avoid), or do nothing about time of exposure to a rewarding/aversive stimulus. To investigate whether approach/avoidance behavior might be governed by quantitative principles that meet engineering criteria for lawfulness and that encode known features of reward/aversion function, we evaluated whether keypress responses toward pictures with potential motivational value produced any regular patterns, such as a trade-off between approach and avoidance, or recurrent lawful patterns as observed with prospect theory. Three sets of experiments employed this task with beautiful face images, a standardized set of affective photographs, and pictures of food during controlled states of hunger and satiety. An iterative modeling approach to data identified multiple law-like patterns, based on variables grounded in the individual. These patterns were consistent across stimulus types, robust to noise, describable by a simple power law, and scalable between individuals and groups. Patterns included: (i) a preference trade-off counterbalancing approach and avoidance, (ii) a value function linking preference intensity to uncertainty about preference, and (iii) a saturation function linking preference intensity to its standard deviation, thereby setting limits to both. These law-like patterns were compatible with critical features of prospect theory, the matching law, and alliesthesia. Furthermore, they appeared consistent with both mean-variance and expected utility approaches to the assessment of risk. Ordering of responses across categories of stimuli demonstrated three properties thought to be relevant for preference-based choice, suggesting these patterns might be grouped together as a relative preference theory. Since variables in these patterns have been associated with reward circuitry structure and function, they may provide a method for quantitative phenotyping of normative and pathological function (e.g., psychiatric illness).

Coevolution in Action: Disruptive Selection on Egg Colour in an Avian Brood Parasite and Its Host:

Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection. Here, we show through detailed field studies and experimental procedures that the ashy-throated parrotbill (Paradoxornis alphonsianus) and its avian brood parasite, the common cuckoo (Cuculus canorus), have both evolved egg polymorphism manifested in discrete immaculate white, pale blue, and blue egg phenotypes within a single population. In this host-parasite system the most common egg colours were white and blue, with no significant difference in parasitism rates between hosts laying eggs of either colour. Furthermore, selection on parasites for countering the evolution of host egg types appears to be strong, since ashy-throated parrotbills have evolved rejection abilities for even partially mimetic eggs. The parrotbill-cuckoo system constitutes a clear outcome of disruptive selection on both host and parasite egg phenotypes driven by coevolution, due to the cost of parasitism in the host and by host defences in the parasite. The present study is to our knowledge the first to report the influence of disruptive selection on evolution of discrete phenotypes in both parasite and host traits in an avian brood parasitism system.

The Effects of Nutrient Dynamics on Root Patch Choice:

Plants have been recognized to be capable of allocating more roots to rich patches in the soil. We tested the hypothesis that in addition to their sensitivity to absolute differences in nutrient availability, plants are also responsive to temporal changes in nutrient availability. Different roots of the same Pisum sativum plants were subjected to variable homogeneous and heterogeneous temporally – dynamic and static nutrient regimes. When given a choice, plants not only developed greater root biomasses in richer patches; they discriminately allocated more resources to roots that developed in patches with increasing nutrient levels, even when their other roots developed in richer patches. These results suggest that plants are able to perceive and respond to dynamic environmental changes. This ability might enable plants to increase their performance by responding to both current and anticipated resource availabilities in their immediate proximity.

Bacterial Gut Symbionts Contribute to Seed Digestion in an Omnivorous Beetle:

Obligate bacterial symbionts alter the diets of host animals in numerous ways, but the ecological roles of facultative bacterial residents that colonize insect guts remain unclear. Carabid beetles are a common group of beneficial insects appreciated for their ability to consume insect prey and seeds, but the contributions of microbes to diet diversification in this and similar groups of facultative granivores are largely unknown. Using 16S rRNA gene clone libraries and terminal restriction fragment (tRF) length polymorphism analyses of these genes, we examined the bacterial communities within the guts of facultatively granivorous, adult Harpalus pensylvanicus (Carabidae), fed one of five dietary treatments: 1) an untreated Field population, 2) Seeds with antibiotics (seeds were from Chenopodium album), 3) Seeds without antibiotics, 4) Prey with antibiotics (prey were Acheta domesticus eggs), and 5) Prey without antibiotics. The number of seeds and prey consumed by each beetle were recorded following treatment. Harpalus pensylvanicus possessed a fairly simple gut community of approximately 3-4 bacterial operational taxonomic units (OTU) per beetle that were affiliated with the Gammaproteobacteria, Bacilli, Alphaproteobacteria, and Mollicutes. Bacterial communities of the host varied among the diet and antibiotic treatments. The field population and beetles fed seeds without antibiotics had the closest matching bacterial communities, and the communities in the beetles fed antibiotics were more closely related to each other than to those of the beetles that did not receive antibiotics. Antibiotics reduced and altered the bacterial communities found in the beetle guts. Moreover, beetles fed antibiotics ate fewer seeds, and those beetles that harbored the bacterium Enterococcus faecalis consumed more seeds on average than those lacking this symbiont. We conclude that the relationships between the bacterium E. faecalis and this factultative granivore’s ability to consume seeds merit further investigation, and that facultative associations with symbiotic bacteria have important implications for the nutritional ecology of their hosts.

The Nature of Working Memory for Braille:

Blind individuals have been shown on multiple occasions to compensate for their loss of sight by developing exceptional abilities in their remaining senses. While most research has been focused on perceptual abilities per se in the auditory and tactile modalities, recent work has also investigated higher-order processes involving memory and language functions. Here we examined tactile working memory for Braille in two groups of visually challenged individuals (completely blind subjects, CBS; blind with residual vision, BRV). In a first experimental procedure both groups were given a Braille tactile memory span task with and without articulatory suppression, while the BRV and a sighted group performed a visual version of the task. It was shown that the Braille tactile working memory (BrWM) of CBS individuals under articulatory suppression is as efficient as that of sighted individuals’ visual working memory in the same condition. Moreover, the results suggest that BrWM may be more robust in the CBS than in the BRV subjects, thus pointing to the potential role of visual experience in shaping tactile working memory. A second experiment designed to assess the nature (spatial vs. verbal) of this working memory was then carried out with two new CBS and BRV groups having to perform the Braille task concurrently with a mental arithmetic task or a mental displacement of blocks task. We show that the disruption of memory was greatest when concurrently carrying out the mental displacement of blocks, indicating that the Braille tactile subsystem of working memory is likely spatial in nature in CBS. The results also point to the multimodal nature of working memory and show how experience can shape the development of its subcomponents.

Bacterial Biodiversity-Ecosystem Functioning Relations Are Modified by Environmental Complexity:

With the recognition that environmental change resulting from anthropogenic activities is causing a global decline in biodiversity, much attention has been devoted to understanding how changes in biodiversity may alter levels of ecosystem functioning. Although environmental complexity has long been recognised as a major driving force in evolutionary processes, it has only recently been incorporated into biodiversity-ecosystem functioning investigations. Environmental complexity is expected to strengthen the positive effect of species richness on ecosystem functioning, mainly because it leads to stronger complementarity effects, such as resource partitioning and facilitative interactions among species when the number of available resource increases. Here we implemented an experiment to test the combined effect of species richness and environmental complexity, more specifically, resource richness on ecosystem functioning over time. We show, using all possible combinations of species within a bacterial community consisting of six species, and all possible combinations of three substrates, that diversity-functioning (metabolic activity) relationships change over time from linear to saturated. This was probably caused by a combination of limited complementarity effects and negative interactions among competing species as the experiment progressed. Even though species richness and resource richness both enhanced ecosystem functioning, they did so independently from each other. Instead there were complex interactions between particular species and substrate combinations. Our study shows clearly that both species richness and environmental complexity increase ecosystem functioning. The finding that there was no direct interaction between these two factors, but that instead rather complex interactions between combinations of certain species and resources underlie positive biodiversity ecosystem functioning relationships, suggests that detailed knowledge of how individual species interact with complex natural environments will be required in order to make reliable predictions about how altered levels of biodiversity will most likely affect ecosystem functioning.

Changing Patterns of Microhabitat Utilization by the Threespot Damselfish, Stegastes planifrons, on Caribbean Reefs:

The threespot damselfish, Stegastes planifrons (Cuvier), is important in mediating interactions among corals, algae, and herbivores on Caribbean coral reefs. The preferred microhabitat of S. planifrons is thickets of the branching staghorn coral Acropora cervicornis. Within the past few decades, mass mortality of A. cervicornis from white-band disease and other factors has rendered this coral a minor ecological component throughout most of its range. Survey data from Jamaica (heavily fished), Florida and the Bahamas (moderately fished), the Cayman Islands (lightly to moderately fished), and Belize (lightly fished) indicate that distributional patterns of S. planifrons are positively correlated with live coral cover and topographic complexity. Our results suggest that species-specific microhabitat preferences and the availability of topographically complex microhabitats are more important than the abundance of predatory fish as proximal controls on S. planifrons distribution and abundance. The loss of the primary microhabitat of S. planifrons–A. cervicornis–has forced a shift in the distribution and recruitment of these damselfish onto remaining high-structured corals, especially the Montastraea annularis species complex, affecting coral mortality and algal dynamics throughout the Caribbean.

The Power of Exercise: Buffering the Effect of Chronic Stress on Telomere Length:

Chronic psychological stress is associated with detrimental effects on physical health, and may operate in part through accelerated cell aging, as indexed by shorter telomeres at the ends of chromosomes. However, not all people under stress have distinctly short telomeres, and we examined whether exercise can serve a stress-buffering function. We predicted that chronic stress would be related to short telomere length (TL) in sedentary individuals, whereas in those who exercise, stress would not have measurable effects on telomere shortening. 63 healthy post-menopausal women underwent a fasting morning blood draw for whole blood TL analysis by a quantitative polymerase chain reaction method. Participants completed the Perceived Stress Scale (Cohen et al., 1983), and for three successive days reported daily minutes of vigorous activity. Participants were categorized into two groups-sedentary and active (those getting Centers for Disease Control-recommended daily amount of activity). The likelihood of having short versus long telomeres was calculated as a function of stress and exercise group, covarying age, BMI and education. Logistic regression analyses revealed a significant moderating effect of exercise. As predicted, among non-exercisers a one unit increase in the Perceived Stress Scale was related to a 15-fold increase in the odds of having short telomeres (p<.05), whereas in exercisers, perceived stress appears to be unrelated to TL (B = −.59, SE = .78, p = .45). Vigorous physical activity appears to protect those experiencing high stress by buffering its relationship with TL. We propose pathways through which physical activity acts to buffer stress effects.

‘Functional Connectivity’ Is a Sensitive Predictor of Epilepsy Diagnosis after the First Seizure:

Although epilepsy affects almost 1% of the world population, diagnosis of this debilitating disease is still difficult. The EEG is an important tool for epilepsy diagnosis and classification, but the sensitivity of interictal epileptiform discharges (IEDs) on the first EEG is only 30-50%. Here we investigate whether using ‘functional connectivity’ can improve the diagnostic sensitivity of the first interictal EEG in the diagnosis of epilepsy. Patients were selected from a database with 390 standard EEGs of patients after a first suspected seizure. Patients who were later diagnosed with epilepsy (i.e. ≥two seizures) were compared to matched non-epilepsy patients (with a minimum follow-up of one year). The synchronization likelihood (SL) was used as an index of functional connectivity of the EEG, and average SL per patient was calculated in seven frequency bands. In total, 114 patients were selected. Fifty-seven patients were diagnosed with epilepsy (20 had IEDs on their EEG) and 57 matched patients had other diagnoses. Epilepsy patients had significantly higher SL in the theta band than non-epilepsy patients. Furthermore, theta band SL proved to be a significant predictor of a diagnosis of epilepsy. When only those epilepsy patients without IEDs were considered (n = 74), theta band SL could predict diagnosis with specificity of 76% and sensitivity of 62%. Theta band functional connectivity may be a useful diagnostic tool in diagnosing epilepsy, especially in those patients who do not show IEDs on their first EEG. Our results indicate that epilepsy diagnosis could be improved by using functional connectivity.

The Brain Functional Networks Associated to Human and Animal Suffering Differ among Omnivores, Vegetarians and Vegans:

Empathy and affective appraisals for conspecifics are among the hallmarks of social interaction. Using functional MRI, we hypothesized that vegetarians and vegans, who made their feeding choice for ethical reasons, might show brain responses to conditions of suffering involving humans or animals different from omnivores. We recruited 20 omnivore subjects, 19 vegetarians, and 21 vegans. The groups were matched for sex and age. Brain activation was investigated using fMRI and an event-related design during observation of negative affective pictures of human beings and animals (showing mutilations, murdered people, human/animal threat, tortures, wounds, etc.). Participants saw negative-valence scenes related to humans and animals, alternating with natural landscapes. During human negative valence scenes, compared with omnivores, vegetarians and vegans had an increased recruitment of the anterior cingulate cortex (ACC) and inferior frontal gyrus (IFG). More critically, during animal negative valence scenes, they had decreased amygdala activation and increased activation of the lingual gyri, the left cuneus, the posterior cingulate cortex and several areas mainly located in the frontal lobes, including the ACC, the IFG and the middle frontal gyrus. Nonetheless, also substantial differences between vegetarians and vegans have been found responding to negative scenes. Vegetarians showed a selective recruitment of the right inferior parietal lobule during human negative scenes, and a prevailing activation of the ACC during animal negative scenes. Conversely, during animal negative scenes an increased activation of the inferior prefrontal cortex was observed in vegans. These results suggest that empathy toward non conspecifics has different neural representation among individuals with different feeding habits, perhaps reflecting different motivational factors and beliefs.

ScienceOnline2010 – interview with Jack, Staten Island Academy student

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Jack from Miss Baker’s Biology class at Staten Island Academy, to answer a few questions. Jack wrote about his experience at ScienceOnline2010 here and wrote a blog post about video/computer games here.
Welcome to A Blog Around The Clock. Would you, please, tell my readers a little bit more about yourself? Where are you from?
Jack pic.jpgI’m Jack, a freshman student who went to Science Online 2010. I am one of Miss Baker’s students and I’m from NJ. I go to school at Staten Island Academy. I currently play the piano but I am planning to get a drum set to teach myself drums, too. I love making things whether it be some random contraption built out of paper or a game to be put online. I always liked making things since I built stuff with legos when I was in lower school.
What is taking up the most of your time and passion these days? What are your goals?
I enjoy using photoshop and flash together to make games. Recently, I decided to also write out my own music for the games. I am currently making a few games that have absorbed most of my free time. Between painstakingly creating graphics and filtering through code to thinking of music for the games, my free time is pretty much gone. As for my goals, I always wanted to design and create new devices or develop new software. I really want to go to M.I.T. for college, and I’ve been doing my best in and out of school to try and get there. On a completely different note, I also want to learn Japanese.
What particular use of the Web in science interests you the most?
I enjoy the amount of freedom that the web gives people, as anyone can access a world-wide database of knowledge for almost any subject. I currently surf the web to find aid in the programming world whenever I have trouble with a script. I also enjoy how the web can be used as a great device for gathering information and doing research. As I move along in developing my programming skills, it is great to talk with fellow programmers to brainstorm possible techniques of getting around difficulties like run time or complex functions.
How does (if it does) blogging figure in your work and school? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do and want to accomplish?
Using Facebook has helped me immensely as it is quicker and more open than e-mailing, so if I or someone else needs a little help with something, they can simply put it up and one of their friends can help out. I also think it is a great way to spread cool articles and facts. Twitter on the other hand has been abused by hundreds of people. No, I really don’t care that you are “enjoying your microwavable pizza” mrtwittrface. Because of all of the “eating this” or “listening to that” tweets on Twitter, I really can’t get into it.
As Miss Baker, when teaching the Biology class, gives you a lot of creative freedom, how does that affect your own interest in the subject? Do you think you learn better this way? What would you suggest to do differently to make it even better? What are some of your own projects you did for the class?
Of course, I found it easier to learn by writing a blog post and commenting on others. Having the creative freedom allowed me to learn what I wanted to, while also allowing the output of the project to be read and understood by people who aren’t just my classmates. Not only was I able to learn about how video games affect the brain, but I also got to make a game and work on my programming.
What was the best aspect of ScienceOnline2010 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?
I loved the fact that people were able to come together for a few days to talk about how the internet is used in science. It was cool to be one of the 8 kids there looking at everything from a different view than most of the other people there. I can’t believe that while I was presenting, Beth Beck (jokingly) asked, “Would you like a job at NASA?” but I was so focused on not messing up that the question just flew over my head. I didn’t want to ruin my opportunity to present at a conference in front of scientists and journalists and everyone else who was there, too. Because of that moment, I’m now working harder than before on my “occupation” of making flash games, as I realized that I could make a positive impact with my programming knowledge, but I need to keep working on getting better first.
It was so nice to meet you in person and thank you for the interview. I hope to see you again next January.

ScienceOnline2010 – interview with Karyn Hede

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Karyn Hede to answer a few questions:
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 (scientific) background?
Karyn Hede pic.jpgI think of myself as a scientist who writes, even though I jumped out of research after graduate school. Most of my formal education is in science. I was biology/chemistry major and then studied genetics in graduate school at the University of North Carolina – Chapel Hill. I should have known I would end up a science communicator though. As an undergraduate, I performed in a “chemistry magic show.” We would go around to elementary and middle schools and get kids involved in the show. It was fantastic to see kids get engaged and to realize that science can be fun. After I committed to making the switch to writing about science and medicine, I studied journalism at UNC-CH. This was well before the medical journalism program existed. I was the oddball. I like to think I helped plant the seed for that program. I’ve spent my whole career telling stories about medicine, science and scientists.
Tell us a little more about your career trajectory so far: interesting projects past and present?
My first professional writing gig was for a local publication called Triangle Business Journal. I talked the editor into letting me write personality profiles of local scientists. My first interview was with George Hitchings, of the [now defunct] Burroughs Wellcome Co., who had just won the Nobel Prize in Medicine. He was so gracious, and I was so nervous! Many years later, I was working as communications officer at the Burroughs Wellcome Fund, a post now occupied by the inestimable Russ Campbell, when Dr. Hitchings passed away. We went over to the old Burroughs Wellcome offices to collect some of his memorabilia for display. They had his personal scrapbook there – he had cut out the article I wrote and put it in his scrapbook. That remains one of the best compliments I’ve ever been paid as a writer.
I was senior science writer at Duke Medical Center for four years. I learned how to put together broadcast-quality video and how to organize and run a news conference. It was a hectic job, and I spent a lot of my time responding to media requests. I discovered I prefer to be on the other side of the equation. I like to be the one asking questions.
Currently, I am a news correspondent for Journal of the National Cancer Institute and for the journal Science’s Careers site. I also write for magazines and science organizations.
What is taking up the most of your time and passion these days?
An undercurrent within my work has always been career development for scientists. When I was a graduate student, you were pretty much on your own as far as exploring career options and developing professional skills. I enjoy teaching and helping support the next generation of scientists. In the last couple of years I have done some consulting work with the North Carolina Biotechnology Center to promote professional science masters programs with the state. We organized a meeting around the issue in 2008. I’ve also been working with Russ Campbell on a series of professional development booklets for scientists. Recently, I started teaching scientific writing for biomedical graduate students at UNC. I taught two courses, one for first-year students and a second course I developed for students who are working their first grant or their dissertation. It’s my way of giving back.
What are your goals?
I am also into gardening and the local food movement. I subscribe to a local CSA at Maple Spring Gardens. A few years ago I organized a session at the National Association of Science Writers meeting to get science writers more interested in covering how our food is produced. Since then, the topic has gotten a lot of coverage, with Michael Pollan’s fantastic books and all the concern over outbreaks of food-borne disease. I’d love to write more about the intersection of science and food production.
What aspect of science communication and/or particular use of the Web in science interests you the most?
I think the wave of the future in science communication is going to be scientists engaging directly with people through their own blogs, videos and websites. Some people (like you!) are naturals and don’t need any help. I know scientists who would like to move more into this arena, but don’t know how to get started. I’d like to work with scientists to help them develop those communication and storytelling skills.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
I read blogs and have gotten story ideas from blogs. I don’t have a blog (yet). I like to let ideas percolate for awhile before writing. The thought of having to produce coherent posts every day (or nearly so) is a bit daunting. My Facebook connections are mostly old friends from college and family. I like LinkedIn for work-related networking – it’s a bit more professional and I like having more control over the content.
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 lived in Washington state for several years and moved back to North Carolina a couple of years ago. In my absence, I discovered an enthusiastic on-line science blogging community had grown up here. I wasn’t surprised. This has always been a science-rich area – blogging is just the latest incarnation of the local science communications community, but with a much wider reach now. I read your blog, Drugmonkey, Female Science Professor, The Intersection, and Terra Sigillata, among others.
What was the best aspect of ScienceOnline2010 for you? Any suggestions for next year?
This was my first time attending ScienceOnline. I was impressed with the sessions and particularly the workshops on Fri. The sessions on visualization in science were valuable, because I was teaching at the time and was able to gather a lot of incredible resources for my students. Meeting so many interesting people who are inventing the future of science communication was great. I’d love to see more of a mashup of working scientists and science communicators shaping the agenda next year.
It was so nice to see you again and thank you for the interview. I hope you can come again next January.

Cory Doctorow in Chapel Hill

Cory Doctorow, blogger at BoingBoing and author of several books, came to town last weekend and did a reading/signing of his latest novel For The Win at Flyleaf Books in Chapel Hill on Sunday.
I assume that, being bloggers and blog-readers, you all know who Cory is and what he does – if not, follow the links above as this post is going to be self-centered 😉
This is the first time I got to meet Cory in person, but he is pretty important person in my life. After I have been blogging about politics for a couple of years and my blog started being well known in the circles of the progressive blogosphere, Kerry/Edwards ticket lost and we all sunk into a collective state of depression. I wrote a few election post-mortems but the wind was out of my sails and I was tired of political blogging.
So I started a new blog in January 2005 and posted a longish blog post about circadian rhythms and sleep in humans. I installed Sitemeter on that one-post blog and went to sleep, only to wake up in the morning to an avalanche of traffic – coming from BoingBoing, linked to by Cory. Soon others linked to it as well, e.g., Andrew Sullivan. To this day, this is still one of the most visited posts in my blogging career and at least once a year it gets rediscovered by someone on digg, redditt or stumbleupon which brings in another mini-avalanche of traffic to it.
That was a wake-up call and an Eureka moment. Aha! Everyone can bash Bush and Cheney, but not everyone can write about science from a position of expertise! I can! On that day I became a science blogger. I knew a handful of science blogs at the time – Intersection, Loom, Pharyngula, Deltoid…but really, the space was still wide open at that time. Very soon, my science blog was receiving as high traffic as the political one, although I kept it very narrowly focused on just chronobiology – talk about a niche blog!
A year later, I was invited to join Scienceblogs.com which widened my audience and enabled me to organize the first science blogging conference (now known as ScienceOnline) and to put together the first science blogging anthology (Open Laboratory 2006). This broadened my audience even more and put my name out there into the media, the science publishing world and Science 2.0 world. As a blogger whose academic library password expired, I naturally became a proponent of Open Access and tended to blog a lot about PLoS papers because I could access them. All of this led to a job at PLoS which I got in the comments of a blog post of mine. That job then led to many other opportunities – speaking invitations, two trips to Europe, various consulting gigs, etc.
So, a single link from someone like Cory can completely alter one’s career trajectory. Just saying. Never hold your links back, you never know how that can help a person one day.
Oh, and you never know what exactly on your blog is interesting to other people. Cory says he loves the Clock Quotes. Go figure!
Anyway, I took a few murky photos at the reading – under the fold:

New and Exciting in PLoS ONE

There are 28 new articles in PLoS ONE today. As always, you should rate the articles, post notes and comments and send trackbacks when you blog about the papers. You can now also easily place articles on various social services (CiteULike, Mendeley, Connotea, Stumbleupon, Facebook and Digg) with just one click. Here are my own picks for the week – you go and look for your own favourites:
Torpor on Demand: Heterothermy in the Non-Lemur Primate Galago moholi:

Hibernation and daily torpor are energy- and water-saving adaptations employed to survive unfavourable periods mostly in temperate and arctic environments, but also in tropical and arid climates. Heterothermy has been found in a number of mammalian orders, but within the primates so far it seems to be restricted to one family of Malagasy lemurs. As currently there is no evidence of heterothermy of a primate outside of Madagascar, the aim of our study was to investigate whether small primates from mainland Africa are indeed always homeothermic despite pronounced seasonal changes in weather and food availability. One of the nearest relatives of Malagasy lemurs, the African lesser bushbaby, Galago moholi, which inhabits a highly seasonal habitat with a hot wet-season and a cold dry-season with lower food abundance, was investigated to determine whether it is capable of heterothermy. We measured skin temperature of free-ranging individuals throughout the cool dry season using temperature-sensitive collars as well as metabolic rate in captured individuals. Torpor was employed by 15% of 20 animals. Only one of these animals displayed heterothermy in response to natural availability of food and water, whereas the other animals became torpid without access to food and water. Our results show that G. moholi are physiologically capable of employing torpor. However they do not use it as a routine behaviour, but only under adverse conditions. This reluctance is presumably a result of conflicting selective pressures for energy savings versus other ecological and evolutionary forces, such as reproduction or territory defence. Our results support the view that heterothermy in primates evolved before the division of African and Malagasy Strepsirhini, with the possible implication that more primate species than previously thought might still have the potential to call upon this possibility, if the situation necessitates it.

Marginal Eyespots on Butterfly Wings Deflect Bird Attacks Under Low Light Intensities with UV Wavelengths:

Predators preferentially attack vital body parts to avoid prey escape. Consequently, prey adaptations that make predators attack less crucial body parts are expected to evolve. Marginal eyespots on butterfly wings have long been thought to have this deflective, but hitherto undemonstrated function. Here we report that a butterfly, Lopinga achine, with broad-spectrum reflective white scales in its marginal eyespot pupils deceives a generalist avian predator, the blue tit, to attack the marginal eyespots, but only under particular conditions–in our experiments, low light intensities with a prominent UV component. Under high light intensity conditions with a similar UV component, and at low light intensities without UV, blue tits directed attacks towards the butterfly head. In nature, birds typically forage intensively at early dawn, when the light environment shifts to shorter wavelengths, and the contrast between the eyespot pupils and the background increases. Among butterflies, deflecting attacks is likely to be particularly important at dawn when low ambient temperatures make escape by flight impossible, and when insectivorous birds typically initiate another day’s search for food. Our finding that the deflective function of eyespots is highly dependent on the ambient light environment helps explain why previous attempts have provided little support for the deflective role of marginal eyespots, and we hypothesize that the mechanism that we have discovered in our experiments in a laboratory setting may function also in nature when birds forage on resting butterflies under low light intensities.

Targeted Manipulation of Serotonergic Neurotransmission Affects the Escalation of Aggression in Adult Male Drosophila melanogaster:

Dopamine (DA) and serotonin (5HT) are reported to serve important roles in aggression in a wide variety of animals. Previous investigations of 5HT function in adult Drosophila behavior have relied on pharmacological manipulations, or on combinations of genetic tools that simultaneously target both DA and 5HT neurons. Here, we generated a transgenic line that allows selective, direct manipulation of serotonergic neurons and asked whether DA and 5HT have separable effects on aggression. Quantitative morphological examination demonstrated that our newly generated tryptophan hydroxylase (TRH)-Gal4 driver line was highly selective for 5HT-containing neurons. This line was used in conjunction with already available Gal4 driver lines that target DA or both DA and 5HT neurons to acutely alter the function of aminergic systems. First, we showed that acute impairment of DA and 5HT neurotransmission using expression of a temperature sensitive form of dynamin completely abolished mid- and high-level aggression. These flies did not escalate fights beyond brief low-intensity interactions and therefore did not yield dominance relationships. We showed next that manipulation of either 5HT or DA neurotransmission failed to duplicate this phenotype. Selective disruption of 5HT neurotransmission yielded flies that fought, but with reduced ability to escalate fights, leading to fewer dominance relationships. Acute activation of 5HT neurons using temperature sensitive dTrpA1 channel expression, in contrast, resulted in flies that escalated fights faster and that fought at higher intensities. Finally, acute disruption of DA neurotransmission produced hyperactive flies that moved faster than controls, and rarely engaged in any social interactions. By separately manipulating 5HT- and DA- neuron systems, we collected evidence demonstrating a direct role for 5HT in the escalation of aggression in Drosophila.

Loss and Recovery Potential of Marine Habitats: An Experimental Study of Factors Maintaining Resilience in Subtidal Algal Forests at the Adriatic Sea:

Predicting and abating the loss of natural habitats present a huge challenge in science, conservation and management. Algal forests are globally threatened by loss and severe recruitment failure, but our understanding of resilience in these systems and its potential disruption by anthropogenic factors lags well behind other habitats. We tested hypotheses regarding triggers for decline and recovery potential in subtidal forests of canopy-forming algae of the genus Cystoseira. By using a combination of historical data, and quantitative in situ observations of natural recruitment patterns we suggest that recent declines of forests along the coasts of the north Adriatic Sea were triggered by increasing cumulative impacts of natural- and human-induced habitat instability along with several extreme storm events. Clearing and transplantation experiments subsequently demonstrated that at such advanced stages of ecosystem degradation, increased substratum stability would be essential but not sufficient to reverse the loss, and that for recovery to occur removal of the new dominant space occupiers (i.e., opportunistic species including turf algae and mussels) would be required. Lack of surrounding adult canopies did not seem to impair the potential for assisted recovery, suggesting that in these systems recovery could be actively enhanced even following severe depletions. We demonstrate that sudden habitat loss can be facilitated by long term changes in the biotic and abiotic conditions in the system, that erode the ability of natural ecosystems to absorb and recover from multiple stressors of natural and human origin. Moreover, we demonstrate that the mere restoration of environmental conditions preceding a loss, if possible, may be insufficient for ecosystem restoration, and is scarcely cost-effective. We conclude that the loss of complex marine habitats in human-dominated landscapes could be mitigated with appropriate consideration and management of incremental habitat changes and of attributes facilitating system recovery.

Phylogenetic Evidence for Lateral Gene Transfer in the Intestine of Marine Iguanas:

Lateral gene transfer (LGT) appears to promote genotypic and phenotypic variation in microbial communities in a range of environments, including the mammalian intestine. However, the extent and mechanisms of LGT in intestinal microbial communities of non-mammalian hosts remains poorly understood. We sequenced two fosmid inserts obtained from a genomic DNA library derived from an agar-degrading enrichment culture of marine iguana fecal material. The inserts harbored 16S rRNA genes that place the organism from which they originated within Clostridium cluster IV, a well documented group that habitats the mammalian intestinal tract. However, sequence analysis indicates that 52% of the protein-coding genes on the fosmids have top BLASTX hits to bacterial species that are not members of Clostridium cluster IV, and phylogenetic analysis suggests that at least 10 of 44 coding genes on the fosmids may have been transferred from Clostridium cluster XIVa to cluster IV. The fosmids encoded four transposase-encoding genes and an integrase-encoding gene, suggesting their involvement in LGT. In addition, several coding genes likely involved in sugar transport were probably acquired through LGT. Our phylogenetic evidence suggests that LGT may be common among phylogenetically distinct members of the phylum Firmicutes inhabiting the intestinal tract of marine iguanas.

Morphological and Molecular Characterizations of Psychrophilic Fungus Geomyces destructans from New York Bats with White Nose Syndrome (WNS):

Massive die-offs of little brown bats (Myotis lucifugus) have been occurring since 2006 in hibernation sites around Albany, New York, and this problem has spread to other States in the Northeastern United States. White cottony fungal growth is seen on the snouts of affected animals, a prominent sign of White Nose Syndrome (WNS). A previous report described the involvement of the fungus Geomyces destructans in WNS, but an identical fungus was recently isolated in France from a bat that was evidently healthy. The fungus has been recovered sparsely despite plentiful availability of afflicted animals. We have investigated 100 bat and environmental samples from eight affected sites in 2008. Our findings provide strong evidence for an etiologic role of G. destructans in bat WNS. (i) Direct smears from bat snouts, Periodic Acid Schiff-stained tissue sections from infected tissues, and scanning electron micrographs of bat tissues all showed fungal structures similar to those of G. destructans. (ii) G. destructans DNA was directly amplified from infected bat tissues, (iii) Isolations of G. destructans in cultures from infected bat tissues showed 100% DNA match with the fungus present in positive tissue samples. (iv) RAPD patterns for all G. destructans cultures isolated from two sites were indistinguishable. (v) The fungal isolates showed psychrophilic growth. (vi) We identified in vitro proteolytic activities suggestive of known fungal pathogenic traits in G. destructans. Further studies are needed to understand whether G. destructans WNS is a symptom or a trigger for bat mass mortality. The availability of well-characterized G. destructans strains should promote an understanding of bat-fungus relationships, and should aid in the screening of biological and chemical control agents.

A Three-Dimensional Atlas of the Honeybee Neck:

Three-dimensional digital atlases are rapidly becoming indispensible in modern biology. We used serial sectioning combined with manual registration and segmentation of images to develop a comprehensive and detailed three-dimensional atlas of the honeybee head-neck system. This interactive atlas includes skeletal structures of the head and prothorax, the neck musculature, and the nervous system. The scope and resolution of the model exceeds atlases previously developed on similar sized animals, and the interactive nature of the model provides a far more accessible means of interpreting and comprehending insect anatomy and neuroanatomy.

The Bank of Standardized Stimuli (BOSS), a New Set of 480 Normative Photos of Objects to Be Used as Visual Stimuli in Cognitive Research:

There are currently stimuli with published norms available to study several psychological aspects of language and visual cognitions. Norms represent valuable information that can be used as experimental variables or systematically controlled to limit their potential influence on another experimental manipulation. The present work proposes 480 photo stimuli that have been normalized for name, category, familiarity, visual complexity, object agreement, viewpoint agreement, and manipulability. Stimuli are also available in grayscale, blurred, scrambled, and line-drawn version. This set of objects, the Bank Of Standardized Stimuli (BOSS), was created specifically to meet the needs of scientists in cognition, vision and psycholinguistics who work with photo stimuli.

Genomic Diversity and Introgression in O. sativa Reveal the Impact of Domestication and Breeding on the Rice Genome:

The domestication of Asian rice (Oryza sativa) was a complex process punctuated by episodes of introgressive hybridization among and between subpopulations. Deep genetic divergence between the two main varietal groups (Indica and Japonica) suggests domestication from at least two distinct wild populations. However, genetic uniformity surrounding key domestication genes across divergent subpopulations suggests cultural exchange of genetic material among ancient farmers. In this study, we utilize a novel 1,536 SNP panel genotyped across 395 diverse accessions of O. sativa to study genome-wide patterns of polymorphism, to characterize population structure, and to infer the introgression history of domesticated Asian rice. Our population structure analyses support the existence of five major subpopulations (indica, aus, tropical japonica, temperate japonica and GroupV) consistent with previous analyses. Our introgression analysis shows that most accessions exhibit some degree of admixture, with many individuals within a population sharing the same introgressed segment due to artificial selection. Admixture mapping and association analysis of amylose content and grain length illustrate the potential for dissecting the genetic basis of complex traits in domesticated plant populations. Genes in these regions control a myriad of traits including plant stature, blast resistance, and amylose content. These analyses highlight the power of population genomics in agricultural systems to identify functionally important regions of the genome and to decipher the role of human-directed breeding in refashioning the genomes of a domesticated species.

ScienceOnline2010 – interview with Sonia Stephens

Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years’ interviews as well: 2008 and 2009.
Today, I asked Sonia Stephens to answer a few questions:
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)?
Sure. I’m originally from Minnesota, but moved to Hawaii when I was young. Now I’m living in Florida. So geographically, I’ve been all over the place, but I probably consider Hawaii “home”. I was always interested in science and nature while growing up – while I was in Hawaii, that interest focused a bit on evolution and extinction. Hawaii is one of the evolution hotspots of the world, and now it’s unfortunately one of the extinction hotspots as well. There are many, many biological, political, social, and economic factors that have combined to create this situation in the Hawaiian Islands. Invasive species, climate change, and dwindling supplies of fossil fuels are some specific problems that make it really obvious that “culture” and “nature” are not, and can never be, separate. This idea made a big impression on me in college, so my interest in ecology now is in this interface of the human and natural worlds.
What is your (scientific) background? Tell us a little more about your career trajectory so far: interesting projects past and present?
Sonia Stephens pic.jpgAt the University of Hawaii, I studied the ecology of stream algae for my Master’s. After graduating, I worked for the National Park Service on a program to inventory and set up a long-term monitoring plan for Pacific Island park natural resources. I started out working on streams and other freshwater ecosystems, some of which are pretty funky, like anchialine pools. These are brackish systems found in rocky coastal areas in Hawaii, connected to both fresh and salty groundwater through crevices in the basalt substrate. They harbor a unique flora and fauna that can cope with tidal changes in salinity. They’re also culturally hugely important, as the only surface-level freshwater on these incredibly hot, dry coastal lava plains. Unfortunately, they’re also hugely threatened by groundwater pollution, coastal development, and invasive species. So these were some of the key resources that the NPS wanted to protect.
The point at which I started to get interested in science communication was when I began working more in-depth on the actual writing of the monitoring plan, as well as coming up with conceptual models and diagrams to illustrate ecosystems and processes (like anchialine pools). I found it really interesting and challenging to translate some of the complicated ideas into pictures as tools to communicate with the public. A whole different question, though, is how to actually get those explanations and illustrations out to people. Traditionally, the NPS creates park displays, which can only be visited in person, and reports and newsletters, which are now downloadable. But these aren’t necessarily the most far-reaching communication methods.
What I’m interested in doing is exploring how scientific organizations can use online tools to communicate with the public. Right now, I’m a PhD student at the University of Central Florida, in the Texts & Technology program. This is a humanities-based program that emphasizes study of digital media, so it’s pretty interdisciplinary in both methodology and subject matter. What I’d like to do is shed some light on what online tools work best for what purposes, and why some tools work better for some types of communication than others.
What is taking up the most of your time and passion these days? What are your goals?
Well, as a grad student, classes and teaching are definitely taking up most of my time. Since my program is based in an English department, I’m teaching college composition this academic year as part of my financial support, which has been quite a learning experience for me. This summer and next semester, I’ll be going into taking my candidacy exams and planning research (assuming the exams go well), so that will take up the majority of my time. In my research, I’m planning to use both visual and science communication theories to look at online science communication. I’m definitely interested in doing some empirical research, but those ideas are still taking shape.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, FriendFeed and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
I don’t have a blog, but I’ve been slowly dipping my toes into the social network aspect of the Internet. Facebook is a great way to keep track of what people are doing, but it does add to the occasional multitasking frenzy, so I’m not sure whether it’s a net positive yet… My main interest in these tools is more along the lines of asking what they’re good for, in terms of working on public understanding of science. I know a lot of writers like to use blogging as sort of a journaling tool, or a place to play with ideas. I’ve never really enjoyed journaling, but I’m starting to see how it might be useful in preparing for my exams (an idea I got from reading Christina Pikas’s blog), so that might be a good way to get started blogging. Right now, I have a fairly basic website online but I’m hoping to upgrade that soon…
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 do read several of the blogs on the Science Blogs site, but honestly I usually just go to the 24-hour feed and look at what posts seem interesting. I do read a couple of nature blogs pretty regularly- one is by Julie Zickefoose, a nature writer & illustrator. and the other is by a birder, Sharon Stiteler. The rest of the blogs I read are generally politically oriented.
What was the best aspect of ScienceOnline2010 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?
Well, one of the questions that seemed to keep coming up at the meeting was: we have all these online tools to communicate with the public, but what tools work best in what situations? There’s a need for research on how well efforts at online science communication work in what situations. Which, obviously, is where I’m trying to go with my studies. I won’t promise to give a complete answer 🙂 but maybe I’ll be able to shed some light on this question.
I also saw a huge diversity of opinion about what science communication is, what blogging is for, whether we should be striving for science literacy vs. public understanding of science, etc. For these more philosophical questions, the answers really depend on the person doing the communicating. I think listening to the talks at the meeting and participating in some conversations helped me clarify some of those answers for myself and think about where I’d like to focus in my work. Personally, I’m involved in environmental activism, and I think that simply educating people about the science behind environmental issues is a huge step in creating sustainable social change. So my focus is on the public understanding of science, with the underlying goal of making the connections between “culture” and “nature” more obvious. Maybe in a few years, if I keep banging my head on a wall of public miseducation about statistics, for example, I’ll shift my focus to science literacy. But for now, I’ll try to start at least a little smaller!
It was so nice to meet you in person and thank you for the interview. I hope to see you again next January.
