New York Times has a nice article reviewing recent research that bears on the genetics of behavior.

ScienCentral also has some interesting new articles: one on hypnosis and cognitive conflict (go to my blog entry for July 6 for the link to a Scientific American article on this subject); one about how baby dolphins and whales and their mothers sleep hardly at all in the first postpartum month -- in stark contrast to other mammalian species; and one on an imaging study that's been looking at what goes on in the brain when we're making moral choices.
