Sci-fi meets wi-fi in a mind over gene experiment

Playing a computer game or letting your mind go to its happy place might one day ease a migraine, administer drugs or prevent epileptic seizures, according to Swiss bioengineers who pulled off a strange mind-over-gene trick. The researchers took advantage of a technique that engineers genes to switch into action in response to light input. But instead of just flipping on a light, they got brain waves to trip the switch. Neither element by itself is all that novel these days. Synthetic biology and cybernetics have brought us the ability to insert DNA that responds to light into the regulatory programming of a gene. Electroencephalogram (EEG) receivers, which detect voltage changes from...
