Darpa stories

To squeeze laser into things like airplanes, we're going to have to make the weapons much smaller and more efficient than the boat-sized platforms we've got right now. DARPA is hard at work on a system called Excalibur that's small enough and powerful enough to make an aircraft like this a reality.
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.
