Just about every animal with a backbone yawns (maybe even dinosaurs), but why we do it is still something of a mystery. A SciFri listener from Texas recently spotted some research that suggests yawning could play a role in clearing waste products from the brain, and asked us to get to the bottom of it. Biomechanical engineer Lynne Bilston, an author on that study, joins Flora to discuss the findings and what they could mean for neurodegenerative diseases like Alzheimer's.
Plus, about a third of Americans aren’t getting the recommended seven hours of sleep per night, according to a new CDC report. We check in with sleep researcher Stuti Jaiswal to break down the report and find out how to get a better night's sleep.
