"Put your thinking cap on" may acquire real meaning if the brain beanie these researchers have developed comes to pass. It could be a major breakthrough for those with serious physical impairments, but it is easy to imagine all sorts of other uses as well. Unfortunately, I keep thinking of applications related to improved ways to change channels--with a "channel beanie," you would not even have to pick up the remote and stab a button...you could just think the channel changed.
