The Human Upgrade: Biohacking for Longevity & Performance

Sea Squirt Plasmalogens Show Brain And Aging Benefits In Old Mice
Aged mice given purified plasmalogen supplements showed better memory performance, healthier synaptic structure, lower neuroinflammation, and increased signaling tied to neurite growth and synapse development, with treated mice even growing thicker, darker, glossier hair. Plasmalogens are specialized lipids concentrated in cell membranes and the brain that tend to decline with age and neurodegenerative disease, making them an intriguing target for cognitive longevity. Host Dave Asprey breaks down why membrane composition matters for brain signaling, mitochondrial function, and inflammation, while stressing that this remains mouse research from 2022 and does not mean eating sea squirts or taking an unproven plasmalogen supplement will reproduce the same effects in humans.

Apple Watch Series 12 Adds More HRV Data, Readiness Scoring, And Health Age
Apple Watch Series 12 pushes deeper into health tracking with heart rate measurements every five seconds, substantially more frequent HRV sampling, a new daily Readiness score, and a Longevity section in the Health app featuring Health Age. Apple is also expanding its health ecosystem with daytime vitals, movement assessments, menopause tracking, and Quest Diagnostics lab ordering for more than fifty biomarkers. Host Dave Asprey explains why higher-frequency wearable data can become useful for spotting changes in stress, recovery, sleep, and illness, but warns against letting algorithmic scores override your own baseline, symptoms, and real-world performance.

FDA Moves To Accelerate Botanical Drug Development
The FDA has opened a formal request for input on how to accelerate botanical drug development, including better clinical trial designs, stronger quality standards, improved standardization of complex plant mixtures, and expanded use of real-world evidence. The agency is also working with the European Medicines Agency on regulatory considerations for herbal and botanical medicines, potentially creating a clearer path for standardized plant-derived therapies to move beyond vague supplement claims and into more rigorous clinical testing. Host Dave Asprey breaks down why this could strengthen the evidence behind compounds like berberine, saffron, medicinal mushrooms, and flavanols, while also warning that more pharmaceutical-style regulation could increase costs and reduce access.

Persistent Adolescent Cannabis Use Linked To Long-Term IQ And Cognitive Decline
A long-running New Zealand birth cohort found that people with persistent cannabis dependence beginning in adolescence showed significant cognitive decline by age thirty-eight, including losses in IQ, memory, processing speed, attention, and executive function. The most persistent users showed an average decline of roughly eight IQ points, while adult-onset users did not show the same pattern, pointing toward adolescence as a potentially important developmental vulnerability window. Host Dave Asprey explains why this 2012 observational study cannot prove cannabis caused every cognitive change, but argues that dose, frequency, age of exposure, and brain development all matter when evaluating cannabis for performance, health, or therapeutic use.

Pterostilbene Helps Mouse Muscle Cells Burn More Fat Through PPAR-Delta
Researchers testing pterostilbene, a polyphenol found in blueberries and grapes, found that it reduced intracellular fat accumulation and increased fatty acid oxidation in cultured mouse muscle cells. Rather than directly activating PPAR-delta, pterostilbene appeared to slow its breakdown, leaving more of the protein available to regulate genes involved in fat metabolism and potentially offering a new mechanistic target for myosteatosis and metabolic dysfunction. Host Dave Asprey explains why the PPAR-delta mechanism is interesting for metabolic health, but draws a clear line between promising cell research and human outcomes, emphasizing that resistance training, walking, muscle mass, and mitochondrial health still have far stronger evidence than taking blueberry extracts to reduce muscle fat.
