Stem cells and electronics can help restore vision to people who've been blinded by retinal diseases, scientists reported in Chicago at Neuroscience 2009, the annual meeting of the Society for Neuroscience.
Diseases of the retina cause blindness by damaging the cells that line the back of the eye, where images of the world are normally transformed into nerve impulses that go to the brain.
A very interesting read.
