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.

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.

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.

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 accessible tool is exactly the kind of practical biohack worth understanding.

Vitamin A Overdoses Surge Nearly 40 Percent

Medical News Today reported a 38.7 percent spike in vitamin A overdoses in early 2025, driven by online misinformation claiming high-dose vitamin A treats or prevents measles, a claim with no clinical support and real toxicity risk from fat-soluble accumulation in the liver. Host Dave Asprey explains the actual hepatotoxicity and bone demineralization risks of preformed retinol excess, draws the critical distinction between preformed retinol and beta-carotene that got lost in the misinformation cycle, and makes the case that mechanism is not a dosing protocol and confusing the two is how people get hurt.

World Cup 2026 and Mass Gathering Health Risk

With the 2026 FIFA World Cup underway, public health researchers are flagging dense international crowds, high-volume travel, and shared indoor and outdoor spaces as an elevated transmission environment for respiratory illness. Host Dave Asprey reframes the conversation away from germ exposure and toward immune terrain, explains why your resilience going into a high-contact environment is a variable you actually control, and lays out the pre-exposure preparation window that matters most for anyone traveling or attending large events this summer.
