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

This nerd thing going on is really bugging me. I went back and re-did the test, changing only 2 or 3 answers to what I did before (not lying, just taking the other one of two possibly correct answers) and got a much higher score: I agree with Jim that the quiz is not really measuring nerdiness so…

Since I already posted, earlier in the week, the weirdest and most disgusting animal sex post ever, instead of writing a new one, I'll just send you to see some cute ladybug sex (scroll down to the middle of the post), which also reminded me of these pictures I dicovered a few months ago. Or…

Global Changes Alter The Timing Of Plant Growth, Scientists Say: Different plant species mature at different times. Scientists studying plant communities in natural habitats call this phenomenon "complementarity." It allows species to co-exist because it reduces overlap in the time period when…

Fifth in the five-part series on clocks in bacteria, covering more politics than biology (from May 17, 2006): In the previous posts in this series, I covered the circadian clocks in Synechococcus, potential circadian clocks in a couple of other bacteria, and the presence of clock genes (thus…

Fourth in the five-part series on clocks in bacteria (from April 30, 2006): For decades, it was thought that prokaryotes did not have circadian clocks. Then, a clock was discovered in a unicellular cyanobacterium, Synechococcus (later also in Synechocystis [1] and Trichodesmium [2]) which quickly…

You may remember this chart from three days ago. Now, Rob Loftis updated his chart after the inputs of a number of bloggers and commenters over the past few days, and John Dupuis has his own chart he uses in teaching about the flow of scientific information.

TNG of Neural Gourmet tagged me with this meme, so how can I resist.... Why do you blog? It's an addiction. It's therapy. It seems a waste if I think about something and don't write it down and let others see it and comment on it. And all of that would count even if I had no audience at all, but…

When Ed announced that Elizabeth Edwards is coming to ConvergeSouth to lead a session about buidling online communities, a bunch of Republican commenters on his blog announced they are not going to show up because of her and found it hard (some, not all of them) to be persuaded that the conference…

The third installment in the five-part series on clocks in bacteria (from April 19, 2006): As you probably know, my specialty are birds, so writing this series on clocks in microorganisms was quite an eye-opener for me and I have learned a lot. The previous two posts cover the clocks in the…

I have a bunch of plants on my porch, mostly ferns, but also some flowers. One of these has really tiny flowers that I thought would be pollinated by small insects - not bigger than a honeybee. So, I was really surprised to see a hummingbird come and sip nectar out of it. Moreover, it is a huge…

Here is a cool microbiology blog, if you can read Slovenian language (I can get the main idea of the post, but not understand every word). This blog is about science in general and this one is about food science.
