With each foiled terrorist attack, airport security eliminates yet another reasonable item from the list of things people are allowed to carry on a plane. As of now, people flying out of the U.K. can't bring any liquids or electronics at all on board with them. Liquids are OK, but electronics… you can only push us so far. Rather than continually annoy travelers with oppressive restrictions, an Israeli-developed system will try to tell if people are hostile before they board the plane. By reading potential passengers pulse, blood pressure, and sweat levels, the device purports to be able to tell if someone is hiding something or planning to blow a plane up using only chewing gum and their RFID-equipped passport. It seems doubtful that the system is sophisticated enough to differentiate between people angry at America for allowing women to drive and people angry at having to get to the airport 18 hours before their flight to go through invasive security screenings, but I guess they're the experts. The system has already begun being tested at an airport in Knoxville, so it seems like it's only a matter of time before you won't be able to fly if you're having a bad day. I think this means the terrorists have officially won. — Adam Frucci
