May 28, 2021 Here's today's feel-good story: A blind Parisian man had his eye injected with genes from algae that use light-sensing proteins. The scientists were able to slowly partially restore the man's vision to the point where he could identify and count objects again. This breakthrough in optogenetic therapy can offer a chance of vision restoration with those that have retinitis pigmentosa which is the degradation of the photoreceptive cells in their eyes.
