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

This post was a response to a decent (though not too exciting) study and the horrible media reporting on it. As the blogosphere focused on the press releases, I decided to look at the paper itself and see what it really says. It was first posted on August 09, 2005. Under the fold (reposted on…
