A hole in the ozone layer above the Arctic caused due to unusual atmospheric conditions, including freezing temperatures in the stratosphere, has closed. The development was confirmed by Copernicus Atmosphere Monitoring Service (CAMS) and Copernicus Climate Change Service (C3S) implemented on behalf of the European Commission. The hole was first spotted by scientists in late March this year.
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.
