- Broadcast from KSQD, Santa Cruz on 9-24-2026: Dr. Dawn warns about a sophisticated phishing scam arriving by mail impersonating post-hack credit-monitoring services from Kroll—the tell being that clicking through prompts for the same personal information the fake letter claims was already breached. ABT-263, an experimental cancer drug that selectively kills senescent "zombie" cells by blocking their BCL-2 anti-apoptotic proteins, dramatically sped wound healing in aged mice (80% healed by day 24 versus 56% in controls) with no effect on young mice—opening potential applications for chronic wounds, diabetic ulcers, and cosmetic use. Dr. Dawn explains why cooling dulls sweetness but enhances saltiness (via cold-activated epithelial sodium channels)—so under-salt hot dishes and don't judge saltiness while food is piping hot. Dr. Dawn walks through when to get stitches: bleeding that won't stop after 10-15 minutes of pressure, visible fat (yellow bubbles) or muscle, jagged edges that won't zipper together, wounds over joints, animal bites, and puncture wounds, and recommends bacitracin over petroleum jelly for initial dressing due to contamination in commonly-used jars. Researchers created a "spud cell"—a barely-living synthetic organism with just 36 genes (from E. coli, viruses, and jellyfish) that divides five times over 12-hour cycles and needs hand-feeding, potentially opening a path to made-to-order cells for cancer treatment, plastic degradation, and carbon capture. Rezdiffra, an analog of activated thyroid hormone T3 that binds only the beta receptor (avoiding cardiac alpha-receptor toxicity), treats metabolic dysfunction-associated steatotic liver disease (MASLD, now affecting 25-40% of adults globally) by boosting fat breakdown and reversing liver fibrosis in patients where diet, exercise, GLP-1 drugs, and bariatric surgery haven't been enough. UK Biobank data from 355,000 people showed that drinking five or more cups of coffee daily was associated with 32% reduced cirrhosis risk and 47% reduced liver cancer risk over 13 years, along with lower liver fat, iron, fibrosis, and inflammation. Men's average testosterone has fallen 54% over the past half-century (steepening after 2000), largely driven by belly fat's aromatase enzyme converting testosterone to estrogen, with hormone-disrupting chemicals and microwaved plastics as additional suspects. Dr. Dawn revisits the 9/11 exposure legacy—28,000 survivors now receiving compensation for asbestos, benzene, and building-fire toxin exposures linked to breast and prostate cancer—and recommends aggressive fiber intake (aim for two large daily bowel movements) and far-infrared sauna sweating as accessible detoxification tools relevant now for those exposed to current fire-season smoke.
