"What were we talking about again? Oh, that's right. Brains. Wonderful, delicious... brains. A new study published in the Proceedings of the National Academy of Sciences shows that researchers can track grey matter for the patterns that precede careless errors. Apparently there's a detectable activity shift when your brain switches to auto pilot -- which can happen as much as half a minute before you screw up. The hope behind the research is to be able to track brain activity and alert users who are headed off the tracks. The technology could reduce work slip-ups, improve driving, or at least help you know when to take a nap or switch activities to keep engaged. But seriously, what were we just talking about?"^^<http://www.w3.org/2001/XMLSchema#string>
