Host Dave Asprey breaks down five emerging health and longevity stories. He covers a mouse study on plasmalogens from sea squirts improving brain aging, the Apple Watch Series 12's new health features including Health Age and HRV tracking, the FDA's move to accelerate botanical drug development, a long-term study linking adolescent cannabis dependence to IQ decline, and research on pterostilbene from blueberries helping muscle cells burn fat. Asprey separates promising mechanisms from premature hype, emphasizing evidence quality and biological context.

Sea Squirt Plasmalogens Show Brain Benefits in Aged Mice00:00:24
Aged mice given purified plasmalogen supplements from sea squirts showed better memory, healthier synapses, less neuroinflammation, and even thicker, glossier hair.
Apple Watch Series 12 Adds HRV Data, Readiness Score, and Health Age00:01:39
Apple Watch Series 12 introduces heart rate sampling every five seconds, a Readiness score, and a Health Age feature in the Longevity section of the Health app.
FDA Moves to Accelerate Botanical Drug Development00:03:38
The FDA has opened a formal request for input on accelerating botanical drug development, including better clinical trial designs and quality standards for plant-derived therapies.
Adolescent Cannabis Dependence Linked to Long-Term IQ Decline00:05:25
A New Zealand birth cohort study found that persistent cannabis dependence starting in adolescence led to cognitive decline by age 38, including an average loss of 8 IQ points.
Pterostilbene Increases Fat Burning in Mouse Muscle Cells via PPAR-Delta00:06:47
Pterostilbene, a polyphenol in blueberries, reduced fat accumulation and increased fatty acid oxidation in cultured mouse muscle cells by slowing PPAR-delta breakdown.
