Mind-blowing medical science

A "vaccine" for brain tumors. A drug-and-electric-shock cocktail that wakes patients out of vegetative states. A single drug that seems to reverse Fragile X syndrome. And gene therapy that allows the blind to see. It's all a little crazy. It's all more-than-a-little for real. (And, hey, that gene therapy for the blind was covered here on BoingBoing a few months ago!)
