A More Delicious COVID Screener One of the most bizarre symptoms of COVID-19—a nearly surefire way to know if you have been infected—is a loss of taste or smell. Estimates of how many people are impacted range wildly, with the highest estimates reaching 75 to 80% of COVID-19 survivors. There’s still a lot scientists don’t understand about why this happens and what part of the olfactory system or brain is actually responsible for this change. Researchers at Ohio State University are trying to figure out more about how COVID-19 impacts taste and smell using a familiar and tasty item: hard candy. Study participants eat an uncolored piece of candy each day and describe the flavor. If a participant is suddenly unable to identify which fruit the candy is emulating … well, it’s time to take a COVID test. Joining Ira to talk about this delicious research and learning more about how COVID-19 impacts our senses is Chris Simons, sensory scientist at Ohio State University in Columbus, Ohio. Laugh And Learn With The Ig Nobel Prizes This year, even though many people may be still hesitant to gather together for the holidays, a Science Friday holiday tradition lives on—our annual post-Thanksgiving broadcast of highlights from the Ig Nobel Prize ceremony, now in its 31st first annual year. Marc Abrahams, editor of the Annals of Improbable Research and master of ceremonies for the prizes, joins Ira to present some of the highlights from this year’s awards—from research into the microbiology trapped in the gum on the sidewalk to a transportation prize for scientists who discovered the best way to safely transport a rhinoceros long distances.
