Scientists can’t yet rebuild someone with bionic body parts. They don’t have the technology. But a new artificial eye brings cyborgs one step closer to reality. This device, which mimics the human eye’s structure, is about as sensitive to light and has a faster reaction time than a real eyeball. It may not come with the telescopic or night vision capabilities that Steve Austin had in The Six Million Dollar Man television show, but this electronic eyepiece does have the potential for sharper vision than human eyes, researchers report in the May 21 Nature.
