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

The beauty of "spacing" children many years apart lies in the fact that parents have time to learn the mistakes that were made with the older ones - which permits them to make exactly the opposite mistakes with the younger ones. - Sydney J. Harris

A dozen or so years ago, I drove my Biochemistry prof to tears with questions - she had 200 people in front of her and she tried hard to make Biochem interesting enough not to get us all bored to tears, and she was pretty good at that, as much as it is possible not to make people bored to tears…

I briefly noted this study yesterday, but now W. D. Craft analyzes it in great detail: I am pessimistic that the authors' more careful conclusions and recommendations will be noticed. Instead I fear we're in for more naive calls for "abstinence education" and coerced virginity pledges.

Also from Miriam, not the famous old (and beloved by my kids) rote memorization of elements - but you will never forget these few basic facts about a few major elements, because it is presented in a viscerally fun way:

Miriam points to this set of pictures of the development of the chicken embryo. As I have written before, I did have to learn how to precisely stage the chick embryos, both the older stages and the early stages, in order to manipulate them at exactly the right time. Cool pics.

Humor is, I think, the subtlest and chanciest of literary forms. It is surely not accidental that there are a thousand novelists, essayists, poets or journalists for each humorist. It is a long, long time between James Thurbers. - Leo C. Rosten
