- Broadcast from KSQD, Santa Cruz on 11-20-2025: Dr. Dawn discusses GLP-1 inhibitors like Zepbound and semaglutide showing unexpected benefits for addiction treatment beyond diabetes and weight loss. Patients in rehab report these drugs mute cravings for alcohol, cocaine, and cigarettes. Multiple studies show reduced substance abuse rates in users, with VA and NIH conducting trials examining brain activity and responses to triggers. With 80,000 annual drug overdose deaths and 48 million Americans having substance abuse disorders, these medications may revolutionize addiction treatment by dampening brain reward circuitry, though costs threaten healthcare budgets. A Stanford twin study found those twins assigned a vegan diet had substantially lower cholesterol, insulin, and body weight compared to their omnivore twins after several months, with LDL dropping 15mg, four pounds more weight loss, and 20% lower insulin. Dr. Dawn explains how a fungal disease decimating Central American frog populations caused 500% malaria increases in some areas. The fungus kills frogs by blocking skin electrolytes until hearts stop, eliminating tadpoles that eat mosquito larvae. Ecosystem collapses followed with algae blooms and snake population drops. She provides other examples showing how species losses affect human health, emphasizing the "one health" movement recognizing ecosystem health as fundamental to human wellbeing. An Australian study found people aged 70+ who listen to or play music regularly had 39% lower dementia rates, though causation remains uncertain. Princeton research shows music activates multiple brain regions simultaneously. Learning instruments increases gray matter, and musical memory remains intact in advanced dementia since it's stored separately from other memories. A caller discusses how modern screen-based activities provide less multisensory engagement than past social experiences like dances. Another caller describes Grover's disease causing persistent itchy skin with no known cause. Dr. Dawn recommends an elimination diet removing common allergens for one month, then reintroducing individually to identify food sensitivities triggering immune responses. Dr. Dawn explains xenotransplantation advances with genetically edited pigs beginning full-scale kidney transplant trials. Companies use CRISPR to disable genes causing immune rejection and insert human genes promoting immune tolerance. With only 10% of global kidney patients receiving organs, these could provide unlimited supply. Other innovations include kidneys with thymus tissue to teach immune tolerance and external pig liver systems as transplant bridges. She concludes noting research showing female dogs remember and prefer humans who demonstrate competence at tasks, while male dogs show no preference.
