Blasts from improvised explosives and RPGs can cause traumatic brain injuries among soldiers, which can leave permanent damage. Sounds like a challenge for the Pentagon's mad science lab DARPA, which has issued a call for a brain freeze device that could stop the after-effects of brain trauma in its tracks, Wired's Danger Room reports.
About a year ago, when resident mad scientist Theo Gray pitched me a Gray Matter column on liquid oxygen, an extremelyflammable energetic form of the element, he first proposed showing how to use it to light a grill nearly instantaneously. The lawyers, however, suggested we go a more tame route, so instead we showed how you could make a few drops of the hooch yourself.
But of course, when left to his own devices (and free of legal oversight), Theo couldn't help himself.
