PhenoNet Cleared By FDA To Begin Phase 3 Trial Of Inhaled Alzheimer's Drug
PhenoNet has received FDA clearance to begin a Phase 3 trial of PHENOGENE-1A, an inhaled formulation of cromolyn sodium, an asthma drug with decades of safety data. Unlike most Alzheimer's therapies, which target only APOE4 gene carriers, this ~648-person trial stratifies both carriers and non-carriers by genotype, testing whether reducing amyloid aggregation, inflammation, and microglial dysfunction can benefit a broader Alzheimer's population than current treatments reach. Host Dave Asprey explains why this genotype-inclusive design challenges the field's narrow focus on APOE4 carriers, and what it means for families with Alzheimer's history who don't carry the gene.

University Of Zurich Researchers Discover The Adult Brain Can Repair Itself Better Than Believed
Researchers at the University of Zurich identified a population of "regenerative astrocytes" in living mouse brains that repair damaged tissue through a previously unknown mechanism: dividing cells send newly formed nuclei traveling across long cellular extensions to repopulate injured regions and rebuild the astrocyte network. The discovery overturns the long-standing assumption that adult brains have limited capacity to replace lost astrocytes after injury or autoimmune disease. Host Dave Asprey unpacks why this finding reframes brain injury recovery as something the body may already be equipped to handle, and what the newly identified genetic pathways could mean for future regenerative therapies.

Sheep's Wool-Derived Keratin Outperforms Collagen In Bone Regeneration Study
Researchers at King's College London developed a keratin scaffold from sheep's wool, a farming industry waste product, and tested it against collagen, the current gold standard, in rats with non-healing skull defects. While collagen produced more total bone volume, the keratin scaffold generated bone that was more structurally organized and closer to natural bone architecture, while remaining stable and integrating cleanly with surrounding tissue. Host Dave Asprey explains why bone quality, not just quantity, matters for weight-bearing repair, and why a cheaper, more sustainable material outperforming the standard is a bigger deal than it sounds.

Oral GLP-1 Pill Aleniglipron Shows 12% Weight Loss In Phase 2b Trial
Structure Therapeutics' oral small-molecule GLP-1 receptor agonist, aleniglipron, produced up to 12.1% weight loss at 36 weeks in a 230-person Phase 2b trial, with no apparent plateau and continued loss to 16% in the open-label extension, putting an oral pill in the same efficacy range as injectable GLP-1 drugs like Wegovy and Ozempic. Host Dave Asprey weighs the compliance advantage of an oral option against his ongoing concerns about muscle loss, rebound weight gain, and the fact that GLP-1 drugs treat a symptom rather than the underlying metabolic cause.

Study Finds 150 Minutes Of Weekly Exercise Falls Far Short Of Real Heart Protection
A Macao Polytechnic University analysis of over 17,000 UK Biobank participants found that the standard 150-minute weekly exercise guideline only reduces cardiovascular risk by 8-9%, while achieving a substantial risk reduction of over 30% requires 560-610 minutes a week, three to four times current recommendations. Only 12% of participants hit that higher threshold. Host Dave Asprey breaks down why public health minimums are a floor, not an optimization target, and what listeners serious about cardiovascular protection should actually be aiming for.

New Research Clarifies The Mechanism Behind IV Vitamin C's Anti-Cancer Effect
Decades after Linus Pauling's high-dose vitamin C claims were dismissed following failed oral-dose trials, researchers have clarified that Pauling had the mechanism right and the delivery method wrong: IV vitamin C bypasses gut absorption limits to reach plasma concentrations up to 100 times higher than oral dosing, generating hydrogen peroxide that is selectively toxic to cancer cells due to their lower catalase levels. A 2024 University of Iowa study found IV vitamin C combined with chemotherapy doubled overall survival in advanced pancreatic cancer patients. Host Dave Asprey reflects on how this vindicates a decades-old idea that was dismissed for the wrong reasons, and what it means for anyone facing a cancer diagnosis.
