Dr. Kiki Sanford makes her eighth appearance on Background Mode. Kiki is a neurophysiologist with a B.S. in conservation biology and a Ph.D. avian neurophysiology from the University of California. She’s a popular science communicator and creator/co-host of This Week in Science (TWIS) podcast and radio show. In this episode, we spend the entire first segment discussing the coronavirus. Kiki fills us in on the details you don’t hear about on the nightly news. In segment #2, Kiki tells us the real reason why people under stress get grey hair, how Mars used to have surface water, how the Earth’s sea level is rising faster than expected, and how zebra strips seem to provide good protection against biting insects. As always, Kiki makes science fun and interesting.
