Its been quite a year for tech developments, although you might not realize until you see a list of them together. Stem cell transplants that keep AIDS at bay. A prosthetic leg that is controlled by the user's mind. Artificial skin that responds to touch -for now made for robots, but who knows what the future holds? There's also a few that are more silly than earth-shattering, like the glow-in-the-dark ice cream in a list of 2013's science fiction-to-fact developments at Buzzfeed.
