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

When my 'Scientific American' arrived the other day, I was excited to read the article about ravens by Bernd Heinrich, as I loved his book Mind of a Raven. I was also glad to see that new cool experiments have been done since the book came out. But I wondering how to blog about an article that is…

As you may have noticed, there is a vigorous debate going on in the blogosphere about framing science (all the links to all the relevant posts can be found if you click on that link). For the uninitiated, this may look as a big dust-up and bar-brawl, but that is how blogosphere works, ya know,…
