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 never thought that I would link to Razib approvingly, but his recent series of posts about evolution of religion are right on the mark. You can start with today's post and follow the links back to his older posts. A good start for a discussion on the topic.

This is the first study I know that directly tested this - the effects of rotating shifts on longevity - in humans, though some studies of night-shift nurses have shown large increases in breast cancers, stomach ulcers and heart diseases, and similar studies have been done in various rodents and…

It has 'Coturnix' written all over it, don't you think? I am even wearing my PLoS t-shirt right now as I am typing this! But, why is it necessary to move to San Francisco? My wife is terrified of earthquakes and CA is one state she always said she would never move to. Looking at the job…

Yup, that was going to be the title of this post. I got the paper and was ready to write the post when I noticed that Peter scooped me and posted about the same paper today (yup, there is just not that many cool papers on Charismatic Marine Megavertebrates to spread around this week). I have…
