We haven’t mastered teleportation yet, but scientists have brought at least one gadget from Star Trek to life… sort of.
German doctors have developed a small optical scanner that can measure your overall health by using light beams to detect the concentration of antioxidants in your skin. In as little as 30 seconds, it will rate your antioxidant levels, and presumably your general health, on a scale of 1 (bad) to 10 (good).
The device is already being tested on 19-year-old German students. So how does it work? And when can we get our hands on one?
if this works, that would be kind of awesome.
