Global licence deal to provide COVID antibody test tech free to poorer countries – WHO
A global licence for serological technology that detects COVID-19 antibodies will be provided royalty-free to poor and middle-income countries under a first of its kind agreement to boost production, the World Health Organisation said on Tuesday.
The existing four tests, which check for the presence of SARS-CoV-2 antibodies developed after either an infection or a vaccine dose, could also inform decisions on the need for boosters to protect against the disease, it said in a statement.
NASA to launch test mission of asteroid-deflecting spacecraft
A SpaceX rocket was set to blast off from California late Tuesday as NASA seeks to demonstrate a first-of-its-kind planetary defense system, designed to deflect an asteroid from a potential doomsday collision with Earth. The DART mission will test NASA’s ability to alter an asteroid’s trajectory with kinetic force – crashing a robot spacecraft into it at high speed and nudging the space boulder just enough to keep our planet out of harm’s way.
Experimental chewing gum may reduce virus spread; Booster shot protection may be longer lasting
The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. Experimental chewing gum reduces virus in saliva
