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.

~~ New Review Of 350+ Studies Asks Whether Less Protein Means Longer Life A review spanning more than 350 studies found that protein restriction consistently extended lifespan and improved metabolic health across mice, rats, flies, and fish, with smaller human studies showing improvements in body fat and fasting glucose even when total calorie intake rose. 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.

~~ Processed Cadaver Skin Injectable Enters The Anti-Aging Market As Elravie Re2O A new injectable called Elravie Re2O, short for "return to your 20s," is made from donated human skin processed to remove living cells and most genetic material, leaving a collagen-rich extracellular matrix that gets injected into the face and neck as a biological scaffold rather than a simple filler. 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.

~~ UCL Study Finds Weekly Arts Engagement Tracks With Slower Epigenetic Aging A University College London study of more than 3,500 adults found that people who engaged weekly with arts and culture, including painting, music, museums, and theater, showed a roughly four percent slower pace of aging on the DunedinPACE clock and appeared about one biological year younger on PhenoAge, with the effect holding after adjusting for income, education, smoking,
