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

Yes, I am one of many SciBlings and other bloggers who got offered to pre-screen Randy Olson's new movie "Sizzle" (check the Front Page of scienceblogs.com for links to all the others). I was reluctant at first, but in the end I gave in and agreed to preview a copy. Why was I reluctant? As a…

What is Web 2.0? Ideas, technologies and implications for education by Paul Anderson: The report establishes that Web 2.0 is more than a set of 'cool' and new technologies and services, important though some of these are. It has, at its heart, a set of at least six powerful ideas that are changing…
