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 thought the LiveJournal debacle taught them a lesson. I guess not. Melissa posted about this a couple of weeks ago, and Tara did it today again because the issue has not been resolved yet. So did PZ Myers (Janet Stemwedel and Dr. Joan Bushwell also chime in). Facebook is deleting pictures of…
