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

A milestone for Abel PharmBoy and Happy Birthday to Olduvai George! Chris asks: how to get alienated kids from inner cities interested in nature? This year saw a sharp rise in the number of multi-author scientific papers. This reflects the increasingly collaborative nature of science - no more…
