Coffee makes it harder to think clearly, while alcohol makes the mind sharper. (At least if you're British.)
Learning to Juggle Causes Changes in the Brain. In a possible twist for the "nature vs. nurture" debate, this study proves "what was not thought possible -- that new stimuli can alter the brain's structure." The head researcher from the University of Regensburg in Germany says "Our results challenge our view of the human central nervous system. Human brains probably must be viewed as dynamic, changing with development and normal learning."
Brain fingerprinting seems to have nothing to do with fingerprinting, but it's still ominous, a step toward a lot of sci-fi dystopias. Don't worry, they'll only use this against criminals and terrorists *cough*
Inattention blindness has been documented in a study of drivers using cell phones. Back when the driving-while-yakking phenomenon first started growing, I told friends I could always tell if the driver of the car ahead of me was on a cell phone: They had a certain style of stupid driving that I couldn't quite describe but I always knew it when I saw it. Now a team of researchers has pinpointed it; they also effectively debunk "you're just as distracted talking to someone in the car"-type analogies. The question remains, now that we know what's wrong with this practice, what do we do about it?
