Last year, University of Texas at Austin alumnus Michael Young won the Nobel prize for discovering the molecular mechanism behind circadian rhythms. Circadian clocks are critical for the health of all living things, acting as the internal timekeepers in plants and animals that help to synchronize functions like eating and sleeping with our planet’s daily rhythm of light and dark. In today’s episode, Young reveals the series of lucky events that launched him into the forefront of circadian rhythm research, what’s really going on in your body when you experience jet lag and how insights from the lowly fruit fly might now help millions of people with sleep disorders.
