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

Or, to tell the traditional Passover joke: A Jewish physicist in the UK was about to get knighted by the Queen. There was a long line of recepients waiting for the ceremony and they were all instructed what to say/chant once they come to face the Queen. The physicist kept silently practicing the…

See, how retouching history works. Retouching, as in 'photoshopping' a photo of a soldiers in Union uniforms into Confederate uniforms, then using the photo as a propaganda material. Hat-tip: Sally Greene

The Eyes Have It! How Box Jellyfish Avoid Banging Into Things: Box jellyfish are much more active swimmers than other jellyfish -- they exhibit strong directional swimming, are able to perform rapid 180 degree turns, and can deftly move in between objects. So how do they manage to manoeuvre the…

One of the big questions in circadian research is how does the transcription/translation feedback loop manage to get stretched to such a long time-frame: 24 hours. If one took into account the normal dynamics of transcription and translation, the cycle would last a couple of hours at best. The…
