- Broadcast from KSQD, Santa Cruz on 9-10-2026: The Pennsylvania measles outbreak has reached 540 confirmed cases with 119 new cases in the past week—the highest yearly count in 35 years, with likely three-fold undercount. Dr. Dawn emphasizes measles' R-value of 14 (versus COVID's peak of 3), its four-day pre-rash contagion window, and two-hour airborne persistence. Lancaster County's pediatric vaccination has dropped from the 95% threshold needed for herd immunity to 87%. She discusses the recent infant death (measles at birth with subsequent splenic rupture during vaginal delivery), the impossibility of vaccinating pregnant women against this live-virus disease, and public health workers doing pop-up clinics and home vaccine delivery. Dr. Dawn criticizes federal threats to strip tax-exempt status and terminate federal grants from universities like UCLA and UC Davis over race-conscious admissions. She argues this targets exactly the schools admitting students most likely to serve underserved communities and enter primary care—where the physician shortage is most acute—rather than dermatology or interventional radiology at tertiary centers. UCLA's Eisenberger social pain lab found that social exclusion (via a rigged game with undergraduates) activates the same brain regions as physical pain (dorsal anterior cingulate cortex and anterior insula on fMRI). A follow-up study showed acetaminophen blunted both self-reported social pain and empathy for others' pain, later replicated with EEG changes in DACC. Dr. Dawn suggests strategic use before stressful social events—though not combined with alcohol. Orexins are wakefulness-regulating neurotransmitters discovered in narcoleptic Doberman Pinschers and Labrador Retrievers. Takeda's oveporexton was approved August 5 as the first orexin agonist for narcolepsy, and Eli Lilly recently paid $8 billion for a related biotech, with Morgan Stanley projecting $16 billion in annual sales. Beyond narcolepsy, orexin agonists show promise for ADHD, attention/motivation, and potentially sleep apnea, with lower abuse potential than methylphenidate or Adderall. A caller advocates for free education and mandatory multilingual instruction in elementary school. Dr. Dawn describes France's tuition-and-food-subsidized medical education with post-graduation community service requirements built in, and shares her own experience with 2% National Defense Student Loans established after Sputnik. Researchers identified a distinctive brain-wave signature marking the transition to unconsciousness under propofol anesthesia—the loss of alpha-band coordination between the parietal cortex and thalamus. Delivered via scalp electrodes, this signature could enable individualized anesthesia dosing and provide non-behavioral markers of consciousness for brain-injured patients. A grandmother caller asks about protecting her first-grader during the measles outbreak. Dr. Dawn confirms two-dose MMR vaccination provides 100% protection against severe measles and 98% against mild disease, and reminds her to prompt women of childbearing age to verify their vaccination status before pregnancy, since maternal measles or COVID infection carries much higher mortality. Researchers studying breath and stool volatile compounds in asthmatic children identified four molecular markers that could enable early sepsis detection through breath analysis. This would prove especially valuable in neonates, where blood cultures are technically difficult, and could provide hours-to-days warning before clinical sepsis manifests. Vaginal birth exposes the infant to maternal vaginal and fecal bacteria that serve as the first beneficial inoculation, with some maternal microbes crossing the placenta prenatally. During the first week of life, maternal antibodies in colostrum and breast milk train the neonatal immune system to tolerate friendly bacteria—preventing later asthma, food allergies, and autoimmune disease. Dr. Dawn highlights colostrum as the critical component and suggests it should be sourced for infants who cannot be breastfed. Magnesium L-threonate crosses the blood-brain barrier efficiently, with about a gram at bedtime improving deep and REM sleep, morning alertness, mood, and productivity. It also reduces migraine severity, and one of Dr. Dawn's patients successfully replaced ADD medications with 3g daily. The only meaningful upper limit is diarrhea, which signals malabsorption.
