Editor’s Selections: Eating Disorders, Climate Change, Penises, And Free Divers

My ResearchBlogging Editor's Selections for the week:

• At Neuroskeptic, the neuroscientist investigates the ways that social networks may encourage the (self diagnosis of eating disorders, such as anorexia.  Specifically, social networks may allow the idea of eating disorders to take root, and consequently increase the rate of patients who identify with having an eating disorder.

• At Wide Urban Word, Michael Smith has an interesting post connecting climate change and population growth as evidenced by changes in the Aztec world.

• At A Primate of Modern Aspect, the primate has penises on the table for discussion: why does the human penis look the way that it does and does it serve a purpose?

• Greg Downey of Neuroanthropology has an incredibly thought provoking post up that investigates the relationship between biology and culture via the stories of free divers.

I'll be back next Thursday to highlight research blogging from the social sciences.
