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 did not have time to go through all the posts on all of today's carnivals, but Larry Moran discovered a real gem on today's Carnival of Education. Check the comments as well. Then come up with your own system.

Joel is collecting links to all the posts written today in honor of the 10-year anniversary of the death of Carl Sagan. The phrase "Science as a Candle in the Dark", the subtitle of Sagan's magnificient The Demon-Haunted World, evokes such a powerful idea that we are fighting for - the…

Somehow I feel that I've been tagged by Janet for this meme, because it is public that we celebrate Hannukkah. But we really make it low-key, family-only, and have only been doing it for about a dozen years so far. Actually, this is the first time that we had guests for the first night. 1. Latkes…

For science bloggers, a study older than a week is often too old to blog about. For scientists, last five years of literature are the most relevant (and many grad students, unfortunately, never read the older stuff). I thought that for journalists, 24-cycle was everything. Apparently not.…

The 29th Carnival of Feminists is up on The imponderabilia of actual life containing posts by several of my favourite bloggers, including Zuska who has her own pick of favourites there. Speaking of Zuska, she also has a cool article in the inaugural issue of the new science-culture Inkling…

Just for the holidays, you get two for the price of one - two simultaneous editions of the Pediatric Grand Rounds: the reverent version and the irreverent version. And no, not all the entries can be found on both. Beware of the pirates on that second one, though.

Too Mellow For Our Predatory World: Flight Behaviour Of Marine Iguanas: Marine iguanas on the Galápagos Islands live without predators - at least this was the case up until 150 years ago. Since then they have been confronted with cats and dogs on some islands of the Archipelago. For scientists,…

OK, everyone is doing this (Janet was the last one I saw), so I'll do it, too. Instead of writing a creative year in review, just copy the first sentence of the first blogpost of each month in 2006. Until June 9th I had three blogs, so I have to pick the first sentence from the first post on each…

Is Internet going to change the way politicians campaign and the way they are perceived? Check this video, the first in a series of "webisodes" filmed behind the scenes with John Edwards: Doesn't that completely change your perceptions? Update: Sorry, forgot the links. You can find this video on…

Apparently, I am not the only one to see a hummingbird in Chapel Hill of a species that should not be found around here. While I am quite confident that the visitor to my porch was a female Blue-throated Hummingbird, usually not found this far North, these neighbors of mine have found a Rufous…

This is my favourite album of all times. The best holiday present I can get. It is not available on tape, CD or mp3 - only an LP. But I can find a way to make a copy somewhere around here. Also, does anyone know if she has ever recorded anything else?

If you really read this blog 'for the articles', you know some of my recurrent themes, e.g., that almost every biological function exhibits cycles and that almost every cell in every organism contains a more-or-less functioning clock. Here is a new paper that combines both of those themes very…

Carnival of the Green #58 is up on Cocolico. It is a strangely formatted blog with no real Permalink and the post is spread over seven pages (you need to keep clicking on the '+' sign). It also looks unusually small (missing my own submission, but perhaps also some others as well). Update: I have…

I can't wait for Night at the Museum! What a perfect movie to take the kids to during the holidays. My son is quite hyped about it - he only nees to decide if he'll go with me or ask a girl out.
