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

Something happened in Siberia 100 years ago - exactly, on this day. I always found the event very intriguing. If you want to learn everything one needs and wants to know about the event, written in a way that will make you excited - go and read Archy's latest masterpiece (hmmm, anthology-worthy?).

Believe it or not, this appears to have something to do with their circadian rhythms! Back in the 1960s and early 1970s, there was quite a lot of research published on the circadian rhythms in earthworms, mostly by Miriam Bennett. As far as I can tell, nobody's followed up on that work since. I…
