Researchers claim to have created an electrochemical eye with a hemispherical retina made of a "high-density array of nanowires mimicking the photoreceptors on a human retina". Their report said its design has a "high degree of structural similarity to a human eye". It even mimics the vitreous humour (gel between the lens and retina) with an ionic liquid, researchers said.
NASA has developed VITAL (Ventilator Intervention Technology Accessible Locally), a high-pressure ventilator in 37 days to treat COVID-19 patients. The device is composed of far fewer parts, many of which are available to potential manufacturers, NASA said. "Its flexible design means it can be modified for use in hospitals being set up in hotels and other high- capacity facilities," NASA added.
