Look Mum, no hands! Two monkeys have managed to use brain power to control a robotic arm to feed themselves. The feat marks the first time a brain-controlled prosthetic limb has been wielded to perform a practical task.

Previous demonstrations in monkeys and humans have tapped into the brain to control computer cursors and virtual worlds, and even to clench a robot hand. But complicated physical activities like eating are “a completely different ball game”, says Andrew Schwarz, a neurological engineer at the University of Pittsburgh, who led the new research.

Tests with humans are being prepared in numerous labs, but experts caution that brain-controlled robotic limbs are far from freeing paraplegics from their wheelchairs or giving amputees their limbs back.
