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

First, we have 199 people registered for the Science Blogging Conference. The Sigma Xi space accommodates 200 and we have ordered food for 200 (coffee for more, to make up for the coffee flop last year) and swag bags for 200. Apart from the public list, we also have a list with a couple of…

No, that is not a really nasty guy who hypnotizes people. It is a technical term used to describe the feeling of falling one sometimes experiences at the moment one drifts into sleep. It often makes the person wake up again. I have not experienced it as kid, and even now it happens to me only…

To keep the conversation about the Science Debate 2008 going, I decided to post, one per day, my ideas for potential questions to be asked at such a debate. The questions are far too long, though, consisting more of my musings than real questions that can be asked on TV (or radio or online,…

Matt and Mrs.Whatsit tagged me with the 7-meme and 8-meme and I have been struggling with the ideas as to how to respond. I am usually a sucker for memes. I always do them. But there is nothing - weird or not - about myself that I have not already mentioned on this blog at one point or another (…

Janet, John and I did this last year. Now John is reminding us again and I hope more people pick it up as it is quite fun to do. The idea is to link back to your first post of each month of the year and to copy and paste the first sentence of each of those posts. Let's see if it is all…

Blind Humans Lacking Rods And Cones Retain Normal Responses To Non-visual Effects Of Light: In addition to allowing us to see, the mammalian eye also detects light for a number of "non-visual" phenomena. A prime example of this is the timing of the sleep/wake cycle, which is synchronized by the…
