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

I did not find it surprising. If you have money, you can buy yourself time - to exercise, to eat a good meal at a nice restaurant or to fix healthy food at home, and to sleep as much as your body needs. As a result, you will be healthier overall. You can read about the study here (hat-tip:…

This post was initially published on September 16, 2004. It takes a critical look at some UCLA studies on brain responses of partisan voters exposed to images of Bush and Kerry: Using M.R.I.'s to See Politics on the Brain The researchers do not claim to have figured out either party's brain yet,…

Some flatworms, for instance these pretty Pseudobiceros hancockanus, engage in penis fencing. Both individuals are hermaphrodites, i.e., have both male and female organs. The penis is white, pointed and two-headed. Both individuals are trying to inseminate the other. The one who is inseminated…

This week, it took me quite a while to figure out how to answer the Ask a ScienceBlogger question: "What are some unsung successes that have occurred as a result of using science to guide policy?" As a relative newcomer to the United States, and even more a newcomer to American politics, I was not…

This is in the bread-mold Neurospora crassa. It is unlikely to be universal. I expect to see the connection in some protists and fungi, perhaps in some animals. I am not so sure about plants, and I am pretty sure it is not like this in Cyanobacteria in which the cycle of cell division is…

I hope you have heard the Diane Rehm Show on NPR this morning at 10EDT (the first hour of the show). The guest was the presiding Episcopal Bishop-Elect Katharine Jefferts Schori, the first woman to lead the Episcopal Church. She is an amazing woman. You should listen to the show here (Real Audio…

Here is a wonderful new study that demonstrates that the antifreeze substances in notothenioid fish are not produced by the liver as was believed for decades and taught in Comparative Physiology courses. Instead, it is produced in two places: most of it in the exocrine pancreas, and somewhat less…

The absence of light-dark cycles in space (e.g., on the shuttle or space station) results in disruptions of sleep. It has been proposed that humans who spend prolonged time in space are suffering from jet-lag - the internal desynchronization of clocks in various tissues. A new experiment on the…

Evolution's Lonely Battle in a Georgia Classroom: OCCASIONALLY, an educational battle will dominate national headlines. More commonly, the battling goes on locally, behind closed doors, handled so discreetly that even a teacher working a few classrooms away might not know. This was the case for Pat…

The fifth installment just came in - read under the fold. (Oh, and BTW, I was wrong - the installments ARE in the correct chronological order) Muyu, extended stay, report (Mu - you, as in newt) I never thought it would come to this, having to give a report on my finds and experiences in the town,…

This post was first written on October 28, 2004 on Science And Politics, then it was republished on December 05, 2005 on The Magic School Bus. The Village vs. The University - all in your mind. Eric at Total Information Awareness wrote two excellent posts on something that touches me personally,…

WHY DAVID BRODER AND MARSHALL WITTMAN THREATEN DEMOCRACY: If you look out over the landscape and think that both sides are equally bad and that the answer is somewhere in the middle, then you aren't looking very closely. In fact, you're not looking at all. You're letting a pre-existing concept (the…

The fifth part of Kevin's snake research in rural China is coming up on this blog today at noon. How do you think Kevin became such a scientist at such a young age? And how can we get more Kevins? Answer: science teachers in our schools. That is why we need to help teachers make science alive…

...so now you know. CFeagans, Mike Dunford and Dave S. were the closest to the correct diagnosis in the comments. You should start a car-repair show on NPR, guys! I also needed - badly - new front tires and alignment. Total cost = St.Peter's scrambled eggs!
