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

Yup, like Amanda, Atrios and Ed, I hate the telephone. That is why I don't have the cell phone. That is why my landline phone has an answering machine. If you call and the machine picks up and I actually want to talk to you at that particular moment, I'll pick up. If not, leave a message and I'll…

There are several journals dedicated to biological rhythms or sleep. Of those I regularly check only two or three of the best, so I often miss interesting papers that occur in lower-tier journals. Here is one from December 2006 that caught my eye the other day: Mammalian activity - rest rhythms…

It is midnight, Day 10, so the contest is officially over. The winner will be announced tomorrow. But that does not mean that you should abandon reading the Beagle Project blog or helping the Beagle Project get advertised and funded.

OK, I have a huge sleep debt to pay back this weekend after a long, tough week of sleep deprivation. I taught my lab this morning which is always exhilarating yet exhausting. Today is always a sad day - this is the fourth anniversary of my Dad's death. I'll have a sip of slivovitz before bed in…

This is interesting: Study: Sleep linked to brain cell creation: The Proceedings of the National Academy of Science research on rats found that the hippocampus portion of the brain was directly affected by a lack of sleep for a long period, the BBC reported. By depriving rats of sleep for 72 hours…

This book, Darwinian Reductionism by Alex Rosenberg, arrived in the mail today. I do not recall ordering it, and I know it used to be on my amazon.com wishlist, so the only explanation is that this is a gift from one of my readers who chose to remain anonymous. I happen to know Alex Rosenberg and…

Children's Sleep Problems Can Lead To School Problems: It is obvious that young children who have difficulties sleeping are likely to have problems in school. A new study shows that African-American children and children from lower socioeconomic backgrounds fare worse than their counterparts when…

Alliance For Science is starting the First Darwin Day Essay Contest for high school students. Go to Neurotopia for all the details about it. I am assuming that this is going to become an annual event. On the other hand, the rebuilding of the HMS Beagle is going to happen only once, for the…

Ah, why do I have to be so busy on a news-filled day (no, not Anna Nicole Smith)? I barely saw the computer today. I'd get home, have about 5 minutes before I have to go out again and so on. NPR did not mention Edwards until 4pm or so (that I heard in the car), so when I first got home I only had…

John McKay is about to become unemployed. I hear political campaigns are hiring bloggers with forceful voices who speak truth to the power. Perhaps anti-mammoth attack-groups will object if he gets hired.

I and the Bird #42 is up on Neurophilosophy blog. Beautiful rendition, formatted like Charles Darwin's diaries from the "Beagle", which - the ship, I mean - as you know (Day 8), is planned to be rebuilt and sailed again, but only if you help.

John Edwards: Statement about Campaign Bloggers: The tone and the sentiment of some of Amanda Marcotte's and Melissa McEwan's posts personally offended me. It's not how I talk to people, and it's not how I expect the people who work for me to talk to people. Everyone is entitled to their opinion,…

The penultimate installment of lecture notes in the BIO101 series. Help me make it better - point out errors of fact and suggest improvements: It is impossible to cover all organ systems in detail over the course of just two lectures. Thus, we will stick only to the basics. Still, I want to…

[Placed on top for updates...] I think that the whole brouhaha that the extreme wingers are raising about new Edwards bloggers will have a) no effect on Democratic primary voters a year from now, b) no effect on national voters two years from now, and c) negative effect on the wingnutosphere as…
