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

No Sex For 40 Million Years? No Problem: A group of organisms that has never had sex in over 40 million years of existence has nevertheless managed to evolve into distinct species, says new research published today. The study challenges the assumption that sex is necessary for organisms to…

A few months ago, Mike defined the Compulsive Centrist Disorder and I have argued something similar a number of times in the past, e.g., here and here. In short - there is no such thing as a political middle. There is no line between "Left" and "Right" that you can put your own dot on. Most…

Crows Can Recognize The Calls Of Relatives: Most of us would know our mother's voice on the phone from the first syllable uttered. A recent Cornell study suggests that crows also can recognize the voices of their relatives. By recording and analyzing the alarm caws of American crows, Jessica…

The first four books in the Cherry Ames series are back in print, published by Springer Publishing Company. Apparently, many people, upon reading them, decided to join the nursing profession. Mind you, that was between 1943 and 1968. when these books first came out. I bet Kim was the first one…

Actually, no, he knows exactly where they went - and for a good reason: Shooting Marbles At 16,000 Miles Per Hour: NASA scientist Bill Cooke is shooting marbles and he's playing "keepsies." The prize won't be another player's marbles, but knowledge that will help keep astronauts safe when America…

Just in case you have not seen it yet, Bee of Backreaction blog has posted an interesting trio of posts well worth reading (each in the series, IMHO, better than the previous): Science and Democracy, part I, part II and part IIi. They are a little physics-centric (especially part I), but if you…

It has been known for quite a while now that bipolar disorder is essentially a circadian clock disorder. However, there was a problem in that there was no known animal model for the bipolar disorder. Apparently that has changed, if this report is to be believed: "There's evidence suggesting that…

You know how on comment threads on blogposts about evolution you, sooner or later, get a commenter saying something that reveals complete lack of understanding of even the basics of evolutionary biology? It is usually accompanied by some creationist canard as well. What do you do? If you stop to…

This is a crosspost to effect a Googlebomb, correcting an injustice against a fellow feminist blogger. Jill Filipovic, who blogs at Feministe and Ms. JD, is a NYU law student who has been the subject of cyber-obsession on a discussion board allegedly populated by law students. The discussions…

Being constantly online and at the same time out of academia skewed my perspective, and I kinda expected that most of my old profs would not be so hot about publishing in online open-sorce journals (and even thinking that Science is still a place to go, oy vey!), but this is quite disheartening,…

Every time someone proposes a radical rewriting of science textbooks, one needs to proceed with caution. There is so much evidence for electrical potentials in nerve cells, this sounds really fishy: Action Of Nerves Is Based On Sound Pulses, Anesthetics Research Shows: Nerves are 'wrapped' in a…

The case is made by an atheist, of course - Amanda - but the important part of the post is the explanation of why is it impossible in the current educational system in the USA and why is the current system inherently conservative.
