FULL EPISODE: Forgotten Memories, Not So Forgotten - August 19, 2026

Astrophysics professor Jesse Rogerson joins the program to cover these science news items: Our survival might one day rely on nuking a city killer asteroid and scientists just tested whether it'll work; Sugar-sweetened beverages linked to stomach cancer for the first time; Ancient humans may have evolved a remarkable trick to survive the last Ice Age; Avocados switch sex on a daily basis, and now we finally know how; NASA rover zapped a rock on Mars and found a gemstone surprise; and Ghosts of forgotten memories may linger in the brain and study suggests they could even be restored. Author Lindsay Owens outlines why she wrote Gouged, a book that explains how companies use technology, hidden fees, data, and other deceptive pricing tactics to charge consumers more. Clinical psychologist specializing in sex therapy Marianne Brandon makes the case that the equality we strive for outside the bedroom accidentally flattens desire, and how being nice to each other sometimes kills sexual tension. Life sciences professor Dr. Ayelet Erez reveals how Viagra's active ingredient appears to trap cholesterol inside cancer cells, potentially limiting their ability to spread.
