Semaglutide Slows Biological Aging A randomized, placebo-controlled study published in Nature Communications found semaglutide slowed biological aging markers by nine percent on the DunedinPACE epigenetic clock in adults living with HIV-associated metabolic disease, with simultaneous improvements across inflammation, heart, kidney, liver, and brain markers. Host Dave Asprey breaks down why this isn't a weight loss story. It's a metabolic inflammation story. He explains why the GLP-1 mechanism hitting insulin signaling, oxidative stress, and inflammatory pathways simultaneously is the real finding, and makes the case that your metabolic markers and your aging markers are the same numbers. Sources: https://www.medicalnewstoday.com/articles/glp-1-drugs-ozempic-wegovy-may-slow-biological-aging https://www.nature.com/articles/s41467-026-72861-3 https://today.ucsd.edu/story/study-popular-glp-1-drug-may-slow-down-biological-aging  FDA Approves First New Sunscreen Ingredient in 20 Years The FDA approved bemotrizinol as a permitted OTC sunscreen active ingredient, the first new approval in roughly two decades, clearing it for adults and children six months and older with broad UVA and UVB coverage and low skin absorption. Host Dave Asprey explains why twenty years of regulatory lag left American consumers with inferior chemistry while Europe moved on, why he's watching independent absorption data before updating his own stack, and why consistency of use matters more than perfect formulation when sun protection remains one of the most evidence-backed longevity interventions available. Sources: https://www.fda.gov/news-events/fda-newsroom/press-announcements/fda-expands-sunscreen-options-first-time-20-years https://www.accessdata.fda.gov/scripts/cder/omuf/index.cfm?event=OrderDetail&orderid=OTC000039 https://www.usatoday.com/story/news/health/2026/06/09/new-sunscreen-ingredient-bemotrizinol/90477659007/  Deoxyribose Gel Matches Minoxidil in Hair Regrowth Study Researchers testing a topical gel made from deoxyribose, the sugar backbone of DNA, saw roughly 80 to 90 percent hair regrowth in a mouse model of male-pattern baldness, matching minoxidil results and showing new follicle formation and increased blood vessel activity in treated areas. Host Dave Asprey breaks down why mouse hair regrowth studies have a long history of failing to translate to humans, what a plausible circulation-based mechanism would actually need to show in human trial data before it's worth acting on, and why the molecule itself is interesting enough to keep watching. Sources: https://www.reddit.com/r/Biohackers/comments/1tyt87w/researchers_found_that_a_gel_made_from/ https://www.sciencealert.com/surprise-hair-loss-breakthrough-a-dna-sugar-gel-sparks-robust-regrowth  Caffeinated Chewing Gum and Exercise Performance A systematic review and meta-analysis of 21 studies found caffeinated chewing gum produces a small but real ergogenic effect for muscular strength and countermovement jump height, with buccal absorption delivering caffeine faster than capsules or drinks in a five to twenty-five minute pre-training window. Host Dave Asprey breaks down why delivery mechanism is an underrated variable in caffeine optimization, why timing matters as much as dose, and why a modest but measurable edge on a cheap and accessibl
