Episode Details

Today's episode reveals a startling connection between periodontal health and white matter damage in aging brains that could change how we think about dental care. We explore microbes thriving in ocean water as alkaline as bleach, challenging what we thought was possible for life on Earth and beyond. Plus, quantum signals successfully transmitted from Earth to satellites, new findings on Enceladus's subsurface ocean that could harbor alien life, and why hair turning gray might actually protect you from melanoma. We also cover revolutionary advances in Alzheimer's treatment, a compact laser system that fits in your palm, and evidence from 9,000 years ago showing how quickly Antarctica can collapse.
