Brains Again 

CalTech researchers have found a way to read monkeys' minds using electrode implants. This has many cool potential applications for helping disabled persons, but also for general human improvement. And abuse, of course. Yay.

Serotonin is, as everyone now knows thanks to marketing campaigns for SSRIs, very important to many brain functions, including mood and appetite and cognition. Given this, there's lots of interest in why some people have more or less than others. Duke researchers have found an allelic(!) gene for an enzyme which directly affects serotonin levels in mouse brains. Plenty of coolness here.
