Farmington, Conn.-based biotech startup Lambdavision Inc. is preparing to test the benefits of microgravity in producing its protein-based artificial retina, thanks to a $5 million, three-year award from the National Aeronautics and Space Administration (NASA). The first-of-a-kind treatment aims to restore vision to people who have lost all or much of their sight due to advanced retinitis pigmentosa (RP).
