Broadcast from KSQD, Santa Cruz on 8-27-2026: Preparing for extreme heat requires a few days of controlled hyperthermia to boost blood plasma volume and trigger heat shock protein production. Dr. Dawn cites research showing that daily 40-minute treadmill sessions in an 80-degree room followed by 40-minute hot baths for six days—or simply an hour daily in a 40°C bath for four days—produces 75-80% of full acclimatization before a heat-zone trip. Five red flags warrant an ER trip for abdominal pain: pain worsening with coughing or car bumps (peritonitis), lack of gas passage with nausea (bowel ob
Broadcast from KSQD, Santa Cruz on 8-20-2026: An emailer asks about amlexanox for mast cell activation syndrome (MCAS). Dr. Dawn first walks through MCAS diagnostic criteria—requiring symptoms across at least two of four categories (skin, low blood pressure, abdominal, respiratory), with serum tryptase testing performed both during and after a flare. She grades amlexanox as a C: originally FDA-approved only as a topical paste for canker sores, later approved in Japan as an asthma treatment, but never validated for MCAS and pushed largely by a single compounding pharmacy and its influencer clon
Broadcast from KSQD, Santa Cruz on 8-13-2026: Dr. Dawn opens by reading an anatomy student's elegy to a body donor, reflecting on how modern medical education has moved away from full cadaver dissection toward pre-dissected specimens and models—and what she believes has been lost in that transition. Dr. Dawn dissects how hospital consolidation has become the primary driver of runaway U.S. healthcare costs. She contrasts a $16,000 knee replacement at Catawba Valley Medical Center with a $40,000 procedure for the same Blue Cross Blue Shield plan an hour away at Asheville's Mission Hospital—a fac
Broadcast from KSQD, Santa Cruz on 8-06-2026: >ul> An emailer with persistent nine-month nerve damage in her right leg after a hysterectomy asks whether peptides could help. Dr. Dawn attributes the injury to lithotomy positioning during surgery, then reviews the main nerve-regeneration candidates in the FDA peptide review pipeline: BPC-157 (Body Protection Compound, strong rat data on sciatic nerve recovery with thicker myelin sheaths), intracellular sigma peptide (targets glial scar CSPGs blocking CNS regrowth), C3 peptide 156-181, GHK-Cu (copper peptide, upregulates nerve growth factor and n
>p>Broadcast from KSQD, Santa Cruz on 7-30-2026: A type of coffee brewed from beans that have been altered by passage through the digestive track of civet cats is a delicacy in Southeast Asia. A Scientific Reports paper using gas chromatography analyzed Kopi Luwak (civet-processed coffee beans) versus fresh-picked beans, finding elevated caprylic and capric acids that carry the characteristic flavor notes found in dairy products. Dr. Manuel Esteller sampled and tested the blood, saliva, urine, and stool of the oldest human Maria Branyas Morera, who died last year at 117. Despite exceptionally
Broadcast from KSQD, Santa Cruz on 7-16-2026: Dr. Dawn dissects a June 2026 JAMA Internal Medicine paper that claimed simultaneous flu and COVID vaccination in veterans reduced cardiac events, arguing the retrospective natural-experiment design cannot support causal conclusions. The 20% versus 2% dropout rates between groups signal fundamentally non-comparable populations, and the divergence in cardiac events starting within a month of vaccination is clinically implausible—suggesting an X-factor other than vaccine effect is driving the numbers. Dr. Dawn delivers a pointed critique of a major c
Broadcast from KSQD, Santa Cruz on 7-09-2026: Researchers refined a technique to reverse skin cell aging by about 30 years while preserving cellular identity. Exposing adult fibroblasts to Yamanaka factors—stopping before full reversion to pluripotent stem cells,reset the epigenetic clock and gene expression patterns to resemble much younger cells. The rejuvenated fibroblasts produced significantly more collagen, migrated faster to close artificial wounds, and showed reversal of gene expression patterns associated with Alzheimer's and cataracts. Since long-term epidemiologic data doesn't yet e
Broadcast from KSQD, Santa Cruz on 7-02-2026: Dr. Dawn devotes the first half of the show to a nuanced defense of GLP-1 receptor agonists, arguing the polarized debate treats obesity as a moral failure rather than a physiological one. She recounts the "Marilyn Monroe dress" moment that transformed semaglutide from diabetes drug into elite cosmetic tool, and pushes back on the puritanical framing that behavior change must be earned rather than pharmacologically enabled—noting we don't apply this logic to antihypertensives or statins. Dr. Dawn catalogs visceral fat as a genuine endocrine organ p
Broadcast from KSQD, Santa Cruz on 6-25-2026: Dr. Dawn devotes the show's opening to ivermectin for COVID. She walks through critical thinking principles—considering the source, cross-verification, and recognizing self-interested claims—before reviewing the evidence. The most-cited 2021 Bulgarian study of 300 people showing 77% reduction lacked accessible methods, and larger trials capable of detecting even small benefits failed to confirm efficacy. On safety, the standard 12mg parasitic dose every few weeks is well-tolerated due to the blood-brain barrier and efflux pumps that keep ivermectin
Broadcast on KSQD, Santa Cruz on 6-18-2026:>/p> Dr. Dawn opens with Virginia Tech research showing yellow fever mosquitoes can learn to associate DEET with blood meals after just four pairings, with over 60% of trained mosquitoes lunging at DEET alone. She emphasizes using DEET at sufficient concentration since under-application could teach mosquitoes a "life lesson" that compromises one of our best protections against malaria, dengue, and Zika. A controversial new theory from the University of Bonn proposes that iron-rich macrophages in the pigeon liver serve as the long-elusive magnetic comp
Broadcast from KSQD, Santa Cruz on 6-11-2026: Dr. Dawn discusses fascia — the gelatinous network of sugary proteins, salts, and collagen bundles that has been known to acupuncturists and osteopaths for millennia but ignored in conventional medical training. New confocal laser endomicroscopy technology has finally visualized this "interstitium" as a fluid-filled space draining to lymph nodes, present throughout the GI tract, urinary bladder, dermis, and peribronchial tissues. The structure may play roles in cancer metastasis, edema, fibrosis, and mechanical tissue function. An emailer asks abou
Broadcast from KSQD, Santa Cruz on 6-04-2026: A caller with previously normal platelets now bouncing between 40-60 asks whether to accept her doctor's recommendation of high-dose dexamethasone. Dr. Dawn suggests checking homocysteine and methylmalonic acid for hidden B12 issues, getting an ultrasound to rule out splenic sequestration, and confirming actual autoimmune antibody testing before committing to steroids. Researchers invented a fake disease called "Bixonimania" (periorbital hyperpigmentation supposedly caused by blue light) with obvious tells including a fictional Asteria Horizon Univ
Broadcast from KSQD, Santa Cruz on 5-21-2026: This is the second show featuring Mira Achilles, a UCSC graduate working on her masters in epidemiology. Dr. Dawn and Mira open with a Harvard study showing OpenAI's o1 reasoning model reached correct diagnoses 67% of the time versus 50-55% for physicians, and scored 89% versus 34% on treatment plans. The AI advantage shrinks when doctors get more data and time, suggesting its greatest value is in fast-moving triage. Dr. Dawn cautions that over-reliance on AI during residency could undermine the clinical reasoning neurologic pathways doctors must d
Broadcast from KSQD, Santa Cruz on 5-14-2026: An emailer from Switzerland follows up on the case of neurological symptoms, warning about the fox tapeworm Echinococcus multilocularis from unwashed garden vegetables and tick-borne encephalitis requiring the FSME vaccine available in Europe. Dr. Dawn adds that cysticercosis from undercooked pork leaves calcified brain lesions detectable on CT scans. Dr. Dawn covers the Andes hantavirus outbreak that sickened at least eleven people on a cruise ship, with the virus spreading person-to-person unlike other hantaviruses. She explains that Andes virus
Broadcast from KSQD, Santa Cruz on 5-07-2026: Dr. Dawn debunks the 1971 "220 minus age" maximum heart rate formula, noting a 2025 study found individual predictions were off by up to 20 beats per minute. She recommends the Tanaka equation (208 minus age) times 0.7, but emphasizes tracking improvement trends rather than absolute numbers. ConsumerLab testing found Safe Catch Wild Elite Pure Tuna and Wild Ahi Yellowfin Tuna had no detectable mercury, prompting Dr. Dawn to reconsider eating tuna after years of avoidance due to concerns about mercury bioaccumulation and its effects on nerve microtu
Broadcast from KSQD, Santa Cruz on 4-30-2026:>/p> Dr. Dawn opens with a bike safety public service message, noting a 34% increase in bicycle use in Santa Cruz alongside rising e-bike accidents. She urges drivers to stay vigilant and calls for education and enforcement of helmet laws, particularly for riders under 18. A University of Michigan researcher discovered that standard nitrile, latex, and vinyl gloves shed stearate particles indistinguishable from polyethylene under spectroscopy, contaminating microplastics research with approximately 2,000 false positives per square millimeter. Only c
Broadcast from KSQD, Santa Cruz on 4-23-2026: Dr. Dawn highlights ARPA-H-funded breakthroughs: Duke researchers created injections enabling cartilage cells to divide and remodel bone, UC Boulder developed intermittent-burst delivery of a repurposed drug that reversed rabbit arthritis in 4-8 weeks, and Columbia printed a living 3D knee using stem cells on biodegradable scaffolding. She notes the agency's budget was cut by $945 million despite requiring human trials within 18 months of funding. A cord blood study across 200 countries links phthalates—found in food packaging, vinyl flooring, sham
Broadcast from KSQD, Santa Cruz on 4-16-2026: Dr. Dawn opens with a follow-up from an email from Maryland about a friend in Switzerland, who has ongoing neurological and gastrointestinal symptoms. She reviews the earlier effort to connect him with functional-medicine resources in Switzerland, then focuses on a new observation that the patient may have had multiple parasitic infections during travel in Europe. Dawn agrees that this may have left a major gap in the workup and says that, in puzzling neurologic cases, a sleep-deprived EEG can sometimes reveal a “fingerprint” of brain-based dysfunc
Broadcast from KSQD, Santa Cruz on 4-09-2026: Dr. Dawn shares a follow-up from an emailer in Switzerland providing seven functional medicine practitioner addresses near Zurich and Aargau, noting that Switzerland uses different terminology but is actually an "epicenter of functional medicine." Dr. Dawn calls for support of the bipartisan Break Up Big Medicine Act, modeled on Glass-Steagall, which would prohibit common ownership of medical providers with insurers, pharmacy benefit managers, or drug wholesalers. She explains how vertical integration by companies like UnitedHealth, CVS/Aetna, and
Broadcast from KSQD, Santa Cruz on 4-02-2026: Dr. Dawn briefly responds to an emailer in Aptos, advising that her numbers don't require rushing into therapy but recommending a more thorough workup. An emailer asks about her sister's osteoporosis treatment, including Reclast side effects and vitamin D levels of 28. Dr. Dawn recommends raising vitamin D to around 50, adding vitamin K2 (MK7-9) and calcium, and suggests weekly oral Fosamax as an alternative to annual Reclast infusions that cause week-long flu-like symptoms. A caller reports dizziness when sitting up in bed and recent fainting epis
Broadcast from KSQD, Santa Cruz on 3-26-2026: li> Dr. Dawn announces a UCSF study recruiting participants for psilocybin therapy to help patients cope with chronic low back pain, requiring ages 25-70 with failed prior treatments. A caller preparing for bladder stone surgery asks about avoiding a repeat of severe post-anesthesia disorientation. Dr. Dawn recommends pharmacogenomic testing through 3x4 Genetics to identify slow acetylator status and other detoxification enzyme variants that can guide anesthesiologists toward better drug choices. A clinical trial found that 24 minutes of music with
Broadcast from KSQD, Santa Cruz on 3-19-2026: Dr. Dawn warns that stacking multiple gummy supplements can cause GI distress from sugar alcohols like xylitol, sorbitol, and mannitol, with symptoms persisting up to three days after stopping. She recommends limiting sugar alcohol intake to 6mg daily and switching to non-gummy formulations if experiencing bloating, cramping, or diarrhea. An emailer asks about finding treatment for abdominophrenic dyssynergia, a condition causing progressive abdominal distension after meals. Dr. Dawn recommends using AI search to locate physical therapy centers off
Broadcast from KSQD, Santa Cruz on 3-12-2026: Dr. Dawn discusses Michael Pollan's critique of MAHA dietary recommendations, agreeing that ultra-processed foods should be avoided but noting the lack of science supporting high saturated fat intake. She acknowledges extra virgin coconut oil as an exception that doesn't raise LDL, and pushes back on the social Darwinism embedded in anti-vaccine, anti-welfare MAHA thinking. Dr. Dawn expresses serious concern about Surgeon General nominee Casey Means, a Stanford-trained physician who dropped out of residency to become a wellness influencer. She obje
Broadcast from KSQD, Santa Cruz on 3-05-2026: Dr. Dawn demonstrates how to critically read a science paper using a widely-publicized study claiming adolescent cannabis use causes psychotic, bipolar, and anxiety disorders. She identifies multiple methodological problems: only 5.7% of Kaiser adolescents admitted cannabis use versus 11.2% in anonymous national surveys, suggesting massive underreporting; the study conflates any use with heavy use; and with 463,000 participants, trivially small differences become statistically significant but clinically meaningless. She proposes reverse causation—t
Broadcast from KSQD, Santa Cruz on 2-26-2026: Dr. Dawn opens with an urgent measles advisory, noting the virus has an R-value of 15 compared to COVID's peak of 5, with South Carolina reporting over 1,000 cases. She recommends those who received only one MMR shot—particularly people now in their 60s—get an immune titer blood test, as protection declines after 40-50 years. Measles can cause "immune amnesia" destroying immunity to other pathogens, and rarely leads to fatal subacute sclerosing panencephalitis years later. Dr. Dawn criticizes Quest Labs' cholesterol reporting, which flags average l
