Thought-controlled robotic arms for humans

Remember last year how scientists said they were able to train a monkey to control a robotic arm using only its thoughts? Well, they've done some more work and are saying that the they should be able to get it to work with humans. [We know that it sounds like we're making up a lot of the posts today (cellphones that analyze skin and measure body fat! loser detectors!), but we swear that this one is real, too.]
