You're looking at some of the most intricate images of live nerve endings ever captured, in which it's possible to make out individual nerves and touch receptors in unprecedented detail.
Get y0ur T-1000 jokes ready, because we're one step closer to liquid metal-powered people. As a team of Chinese biomedical engineers recently used an alloy to close the gap between severed sciatic nerves in frogs. In effect, it made electronic circuits out of nerves—and it worked.
A 71-year-old man who was paralyzed in a 2008 car accident has regained motor function in his hands thanks to Washington University doctors who rewired his nerves to bypass the damaged ones. Though the patient could move his arms, he had lost the ability to pinch and grab with his fingers. Until now, that is.
A neural engineer from Case Western Reserve University is reviving paralyzed limbs with an electricity hack. It's a brilliant workaround for spinal cord injuries, and it may someday let paraplegics activate their legs just by pushing a button.
