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

In a few minutes, I will post the interview with Sen. John Edwards on this blog. All the questions are related to science (and yes, it was not easy to cut down the number of questions and the length of each question - there is so much to ask) so they should be of interest to the readers of this…

What?.... There is a slang phrase in Serbo-Croatian that means "doing nothing; being idle; wasting time", and it is "hladiti jaja", which means "cooling (one's) balls". So, if you see a guy just sitting there, clutching a beer bottle and gazing into the distance, you may ask him "Hey, man, whatcha…
