SCIENTISTS DISCOVER A NEW WEAPON TO STOP THE SPREAD OF COVID-19 INDOORS

ULTRAVIOLET LIGHT HAS A LONG HISTORY AS A DISINFECTANT AND THE SARS-COV-2 VIRUS, which causes Covid-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight the spread of the virus and protect human health as people work, study, and shop indoors. The virus spreads in several ways. The main route of […]

Can far-UVC light reduce the spread of COVID-19 indoors?

Can far-UVC light reduce the spread of COVID-19 indoors?

A decade or so ago, David Brenner, a professor of radiation biophysics at Columbia University Irving Medical Center in New York began thinking about the problem of drug-resistant bacteria. He’d lost a close friend to the scourge—that friend had gone to the hospital for routine surgery and died of a superbug he’d acquired while there. […]
