Darpa stories

Even through traumatic brain injury has the word "traumatic" in it, it's often the case that soldiers in combat are exposed to things blowing up that leave mild to moderate brain injuries that go undetected. DARPA's new field blast gauge is designed to help medics tell exactly how much blast exposure someone has, and whether they need treatment.
A world full of flying cars certainly sounds like an impossible dream, but if it did happen, wouldn't it be nice for them to fly automatically to boot? It'd be either that, or we'll all have to get pilots licenses. Carnegie Mellon is indeed working on a system to have cars fly themselves, but not just any soaring car — DARPA's Transformer.
