My scientific specialty is chronobiology (circadian rhythms and photoperiodism), with additional interests in comparative physiology, animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. As well as writing this blog, I am also the Online Discussion Expert for PLoS. This is a personal blog and opinions within it in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com

Mindy discovered a cool series of videos on YouTube, done by a physics teacher. The first one is called The Most Terrifying Video You'll Ever See: Then, to respond to questions and comments, he added Patching Holes #1, Patching Holes #2 and Patching Holes #3, also well worth watching. This is…

Well, I have the reputation about blogging around the clock, but every year more and more bloggers take that idea literally and they do it for one day for good cause, as a part of Blogathon. Bill explains: The mechanics are simple: bloggers sign up to blog for their chosen charity, and sponsors…

I can't stay away (a charming spell?) from the series that Anne-Marie is churning out at a supernatural rate (what kind of magic?). Here are the latest three installments, totally enchanting: Conservation Biology The Botany of Wands Kin selection

The third post in the series on entrainment, first written on April 10, 2005, starts slowly to get into the meat of things...As always, clicking on the spider-clock icon will take you to the site of the original post. In the previous post, I introduced the concept of entrainment of circadian…

Kim of Emergiblog explains nicely why you should support Open Access publishing: The Public Library of Science: You are writing a paper. You need to do some research, so you google your topic. Ah ha! There it is! The perfect article for your paper. The abstract is right in front of you, but you…

The Purloined Bibliography: My training in medieval history had acquainted me with the practice of identifying dependencies among manuscripts by tracing the repetition of errors. By analogy, I thought, if there were additional idiosyncratic errors on my Web site that also appeared in the book, each…

My SciBling Rob Knop is leaving the academic circus for a cool job: designing Universes or some such astronomical stuff on Second Life. Just as he is about to leave his University, though, he got a nice parting gift from the academic world for his work on the expansion of the Universe - the Gruber…

Jonathan Eisen demonstrates with a personal example. First he did a keyword search for the topic of his interest and expertise. Then he read a paper that came up in the search. Then he rated the paper and left a brief comment with the rating. Then he came back to his blog, wrote in more detail…

This is the second in a series of posts on the analysis of entrainment, originally written on April 10, 2005. The natural, endogenous period of circadian rhythms, as measured in constant conditions, is almost never exactly 24 hours. In the real world, however, the light-dark cycle provided by the…

Russ Williams (Director of NC Zoo Society) reports on his blog that the North Carolina Zoo is experiencing record attendance. He also notes that San Francisco Zoo is enjoying record numbers as well. Why do you think zoos are so popular lately? Finally, he mentions that in the Oakland Zoo, one can…

This crept up on me - I was unaware it was so close yet. I just saw it and had to capture this historical moment: The 500,000th visitor came from Reading, UK. After all this time, I still wonder why so many people come here so often: is watching compulsive blogging akin to watching a wreck? You…

The Wall Street Journal has an article about blogs, written by 10 or so people. Some of it is good, some of it is bland and out-of-date, and you can just skip Tom Wolfe's piece (via Ed Cone). Also, check out 55 Essential Articles Every Serious Blogger Should Read (which makes it the 56th such…

I missed this by weeks, but Dave asked a set of questions that I was pondering on, but found no time and energy to answer until now. PZ, Janet, Martin, Chad and RPM responded (I am assuming some people outside SB did as well) and their responses (and their commenters') are very interesting. 1. What…
