North Korea's leader Kim Jong-un is in "grave danger" following a surgery, CNN reported citing an anonymous US official. Separately, a Seoul-based website run mostly by North Korean defectors reported that Kim underwent a "cardiovascular surgical procedure" and was now mostly recovered. His health has deteriorated in recent months due to heavy smoking, obesity and overwork, it added.
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.
