Longevity

Summer 2025 delivered three milestones for mitochondrial medicine: births after mitochondrial donation in the UK, an FDA-cleared Phase II cell therapy for Pearson syndrome, and precise base edits in animals and patient cells. Here is what is real, what is risky, and how this momentum could shape healthspan.

Loyal’s senior-dog pill just passed the FDA’s Reasonable Expectation of Effectiveness bar, opening a path to conditional approval. Here is what RXE certifies, why the veterinary-first route matters, and how a 2026 launch could become real.

With the FDA’s 2024 LDT rule vacated and CLIA back in the driver’s seat, aging biomarkers from methylation clocks to proteomic panels are racing into clinics. Here is what reopens, who benefits now, and a 6 to 12 month playbook to do it credibly.

For the first time, U.S. regulators have authorized formal studies of gene-edited pig kidneys. Here is what changes for patients, safety, and longevity if xenotransplantation moves from one-off surgeries to scalable care.

An NIH analysis in Science on June 5, 2025 reports that circulating taurine does not consistently track aging in humans, monkeys, or mice. We explain biomarker versus endpoint, where human trials stand, and how to read longevity claims with discipline.

Swiss Re modeling suggests GLP-1 drugs could reduce U.S. mortality up to 6.4 percent by 2045. With new Phase 3 data on oral semaglutide, we unpack biology, durability, biomarkers, trials, payer models, and equitable access.

Cross-organ signals from Life Biosciences at ARDD 2025 move partial epigenetic reprogramming from hype to clinical planning. Here is what it means for delivery, safety, endpoints, first indications, and regulatory strategy.

Lilly’s July 2025 purchase of Verve puts one-shot PCSK9 base editing on a fast track from lab signal to real-world prevention. Here is what the data showed, the risks, the regulatory path, and what to watch next.

Rubedo dosed its first patient with RLS-1496 in May 2025, launching the first human test of a GPX4-modulating senolytic. Here is how ferroptosis could define senolytics 2.0, which skin biomarkers will matter, and what a credible 2026 systemic program could look like.

A randomized human study in 2025 reported multi-omics rejuvenation signals after therapeutic plasma exchange, strongest when IVIG was added. Here is what the data means, how clinics plan to scale, and what the next randomized trials must prove.

PEARL's 48-week randomized trial in healthy adults reports acceptable safety, sex-specific gains in lean mass, and less pain in women, with no change in visceral fat. Here is what that means for healthspan and what a real Phase 3 must prove.

{"value":"Retro Biosciences plans to dose its brain-targeted autophagy inducer, RTR242, in a 2025 first-in-human study in Australia. Here is what the trial will likely test, which biomarkers matter most, and how this approach stacks up against rapalogs and supplements."}

Veterinary anti-aging just crossed a regulatory threshold. The FDA’s CVM granted RXE to Loyal’s LOY‑002 while the Dog Aging Project restarted its TRIAD rapamycin trial, signaling that geroscience is moving into everyday practice.

A single AAV dose of secreted Klotho extended male mouse lifespan in a 2025 study, while a biotech began manufacturing an AAV‑Klotho candidate for ALS. Here is the biology, delivery tradeoffs, safety map, endpoints, and timelines that matter now.

A 2025 case study of supercentenarian Maria Branyas Morera reveals low inflammation, a youthful microbiome, protective genes, and a younger epigenome. The findings shift longevity science toward resilience and trial designs that measure recovery and function, not just age.

After a March 31, 2025 court ruling, FDA formally rescinded its 2024 LDT rule on September 19, 2025. Epigenetic clocks and proteomic biological age panels shift back under CLIA. Here is what is defensible now, how to validate, and what to watch next.

Fresh August 2025 cardiology genetics data suggest that low-dose colchicine may slow TET2-driven clonal hematopoiesis in people with coronary disease. Here is what CHIP is, who to test, and how to act while we wait for genotype-enriched trials.

New 2025 data suggest GLP-1 combinations can shift weight loss toward fat while protecting muscle. Here is how ActRII and myostatin strategies, amylin add-ons, and smarter training could make weight loss longevity-safe for older adults.
