Light Could Make Paralyzed Limbs Move 63 63

Zothecula writes "In a study that could eventually restore movement to humans' paralyzed limbs, researchers at California's Stanford University have used light to induce muscle contractions in mice. A gene derived from algae was inserted into the mice, encoding a light-sensitive protein which adhered to their nerve cell surfaces. Scientists then placed an 'optical cuff' lined with tiny, inwards-facing LEDs around the mice's sciatic nerves. By penetrating those nerves with brief, high-intensity bursts of blue light, they were able to produce muscle contractions similar to those that would occur naturally. The technology is called 'optogenetics.'"

Twitter isn't the only form of electronic communication. It is, however, the most asinine and informal. I wouldn't want the news of my upcoming demise originating from the same site responsible for informing millions that Lance Armstrong woke up and is preparing a delicious sandwich.
