Using a bioluminescent substrate that reacts with SARS-CoV-2 spike protein (shown in the insert), researchers have devised a potential one-minute COVID-19 test. Credit: Ryo Nishihara Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine … Read more
