Sniffing out trouble …You’ve probably tested yourself for COVID by now, and soon you’ll be able to test everyone else – with a new wearable COVID detector. While it’s not on sale just yet, Yale University researchers say they’ve perfected something called Fresh Air Clip. The clip-on device can detect very low levels of the virus that causes COVID-19 in the air, making it easier to sense if you’re entering a danger zone. Sure beats having to swab your neighbor’s nose!
