Here's a pretty amazing story:
Four people were able to control a computer using their thoughts and an electrode-studded "thinking cap," U.S. researchers reported on Monday.
While experiments have allowed a monkey to control a computer with its thoughts, electrodes were implanted into the animal's brain. This experiment...required no surgery and no implants.
One hardly knows what to say. This is one of those scientific breakthroughs that I find both exhilarating and terrifying.
