Subtitle: A Nasal Spray Longevity Screen, Why Less Protein May Age You Better, Cadaver Skin Injectables, Art's Effect on Biological Age, and Which Anti-Aging Interventions Actually Move the Needle Nasal Spray Ingredient Emerges As Unexpected Longevity Candidate In Massive Drug Screen Researchers mapped 2,358 longevity-associated genes across the body's broader protein and signaling networks, then screened 6,442 approved drugs to see which ones nudged those aging pathways in a healthier direction. Oxymetazoline, the active ingredient in nasal sprays like Afrin, was among 21 standout candidates, with a predicted pathway running through the ACKR3 receptor and connecting to major aging proteins including NF-kB, TP53, and AKT1. Host Dave Asprey explains why this computational screen is a promising research lead rather than a protocol, and why chronic use of a vasoconstricting nasal spray carries real risks regardless of what a network analysis suggests.

Researchers point to FGF21, a liver hormone that rises under protein or amino acid scarcity and boosts energy expenditure and glucose regulation, as a key mechanism. Host Dave Asprey breaks down why blanket protein advice fails older adults preserving muscle and highly active people just as badly as it fails everyone else, and why matching intake to actual biology beats maximizing protein at every meal.

Human-derived tissue matrices already have a track record in burn and wound care, but this specific product is not yet FDA-approved and lacks comparative trial data against existing fillers. Host Dave Asprey separates legitimate regenerative medicine from a novel cosmetic product still waiting on long-term safety and consistency data.

Benefits appeared whether people were actively creating art or simply attending performances and exhibits. Host Dave Asprey argues this expands what counts as a health input beyond molecules and devices, since novelty, meaning, and social connection influence the nervous system too.

Semaglutide produced the strongest single result, slowing DunedinPACE by about nine percent in a trial of adults with HIV-associated fat redistribution, though a separate fatty liver study produced mixed outcomes. Host Dave Asprey explains why a strong mechanistic story does not guarantee a moved biomarker, and why clinical outcomes, functional measures, and safety data all matter alongside any single clock reading.

Host Dave Asprey connects computational biology, nutrition science, regenerative medicine, and biomarker research into practical frameworks for evaluating what belongs in a real longevity protocol versus what belongs on a watch list.
