A new generation of retinal implants could use light to provide power and data, potentially restoring vision in a less-invasive form than existing implants. Researchers at Stanford University previously described how such a system would work, and now they’ve designed implants that can receive infrared signals for power and information processing.
Glaucoma affects more than 4 million Americans, many of whom don’t even realize they are affected by it. It’s a leading cause of blindness with no known cure. But researchers at the non-profit Jackson Laboratory have found that a single, targeted X-ray treatment of a single mouse eye is enough to provide complete and lifelong protection from glaucoma, even in mice who are prone to the disease.
