Longevity Roundup — 31 May 2026
The week’s most relevant longevity research and commentary, curated by The Health Clinic Stockholm.
This week brought new data on how your own self-perception of aging predicts your physical activity years later, a Phase 1 epigenetic-reprogramming trial moving forward in humans, and a reminder from Bryan Johnson that chronic stress shows up in your biology long after it’s gone. Six items worth your attention.
1. How you think about aging predicts how active you’ll be — four years later
A 4,947-person UK PROTECT cohort study found that adults who perceived more age-related losses were significantly less physically active four years later, with depressive symptoms partially mediating the link. The negative self-perception → less activity pathway held across number, duration, and intensity of exercise.
Practical implication: how older patients narrate their own aging may matter as much as the physiology — interventions that reframe aging may unlock more movement than pure exercise prescriptions.
2. A traditional Chinese herb extends lifespan in yeast and flies — via the PI3K-AKT pathway
Dendrobium officinale extracts extended lifespan in both yeast (Saccharomyces) and fruit flies (Drosophila), and rescued high-sugar-diet-induced lifespan loss. The mechanism: context-dependent modulation of the highly conserved PI3K-AKT signaling pathway, with downstream FOXO activation.
Why it matters: PI3K-AKT-FOXO is the same axis implicated in rapamycin, metformin, and dietary-restriction effects on lifespan. Still pre-mammalian, but mechanistically interesting.
3. Bryan Johnson: “The Biological Cost of Stress”
A piece by Vanessa Gibbs on how present-day psychological stress accumulates as measurable biological changes that persist for years. Covers the physiological mechanisms by which stress raises biological age and points to chronic stress as one of the most underrated longevity variables.
Useful framing for anyone tracking biomarkers but ignoring HRV, sleep, and recovery.
4. Bryan Johnson: “12 Phone Habits for Better Health”
A practical companion piece arguing that smartphone usage patterns are an underappreciated lever on biological age, with twelve specific habit modifications. Many overlap with what we already know about sleep hygiene and circadian rhythm protection, but the framing as a biological age intervention rather than productivity is novel.
5. Rhonda Patrick Q&A #81: beta-glucan for PFAS, urolithin A, sauna, and IVF supplements
Dr. Patrick’s monthly listener Q&A covers oat beta-glucan fiber as a possible binder for “forever chemical” (PFAS) excretion, the current evidence on urolithin A and mitophagy, exogenous ketones, supplementation strategies for IVF, sauna protocols, and Botox safety.
Worth listening for the PFAS and urolithin A segments specifically — both have meaningful new evidence in 2026.
6. Update: Life Biosciences’ epigenetic reprogramming trial — the human test of Sinclair’s information theory of aging
Life Biosciences (co-founded by Harvard’s David Sinclair) received FDA approval in January for the first human trial of partial epigenetic reprogramming — the technique uses modified Yamanaka factors to “reset” the chemical tags on DNA in aged cells. The Phase 1 trial targets glaucoma and non-arteritic anterior ischemic optic neuropathy (NAION), with first-patient readouts expected late 2026 / early 2027.
Why it matters: this is the most consequential live test of Sinclair’s Information Theory of Aging — whether the same approach that restored vision in aged mice will translate to humans. Worth following over the rest of the year.
