We are thrilled to pass along the news that Scientific American has won this year's prestigious Science in Society award, given by the National Association of Science Writers, for the essay Ban Chimp Testing that appeared online and in our October 2011 issue...
Two-part barbed penises, a physical struggle and 20 minutes of penetration. That's how some sea slugs do it.
