Chinese researchers have reportedly made a breakthrough in artificial vision technology using a rare mineral called tellurium. This development could one day help restore sight to the blind, perhaps even enhancing it beyond natural capabilities.

The breakthrough was made by researchers at Fudan University in Shanghai, who developed an artificial retina implant composed of tellurium nanowires. These wires, the team reports, were then implanted into blind mice who miraculously regained their vision.
