Protein ReHMGB1 linked to spreading aging signals in mice
A mouse study from Korea University, published in the journal Metabolism, suggests that the protein ReHMGB1, released by senescent cells, may cause aging-like effects in distant tissues. Blocking the protein with antibodies was associated with fewer aging signs.
Retro Biosciences begins Phase 1 trial of aging drug candidate RTR242
The article reports that Retro Biosciences has started a Phase 1 trial of RTR242, a small molecule linked to cellular cleanup. The trial is randomized, placebo-controlled and enrolls healthy volunteers.
SIRT6 Enzyme Linked to Tryptophan Shifts in Aging Brains
A report describes how SIRT6 levels fall as the brain ages, shifting tryptophan toward the kynurenine pathway. The findings come from animal studies and are preliminary.
Article claims diabetes drug henagliflozin lengthened telomeres in a trial
An article reports a 26-week trial of henagliflozin in which more treated people had longer telomeres than those on placebo. The result is preliminary and needs independent verification.
Blood proteins may reveal uneven aging across cell types
An article reports that blood proteins from more than 60,000 people may help measure aging in specific cell types, which could be relevant to understanding disease risk.
Cyb5b protein and gene switching by electromagnetic fields in a mouse study
A study from a Seoul group, reported in the journal Cell, describes the Cyb5b protein as a possible switch for genes under electromagnetic fields. The results are preliminary and come from animals, not people.
Gene in worms and lifespan: what a social media post reports
A social media post describes experiments with worms in which switching off one gene reportedly doubled lifespan, including in older worms. The result has not yet been checked against a peer-reviewed publication.
Human partial reprogramming eye study for glaucoma and NAION completes enrollment
A first-in-human study testing partial cellular reprogramming in the eye has completed enrollment. Safety data are expected in Q4 2026, and no efficacy results have been released yet.
Information loss theory of aging: an unproven hypothesis from a 2008 lab
An article presents the claim that aging may stem from loss of epigenetic information after DNA breaks, citing 2008 work from a Sinclair lab. It is a debated hypothesis, not a proven result.
Partial cell reprogramming and aging in mice
A social media post describes studies in mice in which partial cell reprogramming made old animals younger and, according to the text, about 30% longer-lived. The results come from animal research.
Senolytic and NAD-boosting combination extended mouse lifespan by 33%
In mice, an oral combination of quercetin, NR, urolithin A and alpha-lipoic acid, started at 18 months of age, increased median remaining survival by 33%. The results are early and do not show an effect in people.
SGLT2 inhibitor linked to longer telomeres in diabetes trial
A randomized, double-blind trial of 150 adults with type 2 diabetes linked henagliflozina, an SGLT2 inhibitor, to longer telomeres after 26 weeks, compared with placebo.
Three-Year Study Reports Brain Health Gains at Advanced Ages
A three-year study of nearly 4,000 adults reported improved brain health at any age, including people in their 80s and 90s. The researchers say the results challenge the idea that cognitive decline is inevitable.
An Opinion Piece Argues Aging Mixes Random Damage and Regulated Processes
An opinion article, citing an unnamed review, proposes that aging combines accumulated errors whose rate is shaped by evolved regulatory networks, rather than being either purely random damage or programmed death.
Ant study links a peptide to caste switch and longer lifespan
A study in Harpegnathos ants reports that the peptide HCRG1 suppresses juvenile hormone and coordinates changes in reproduction and lifespan in these insects.
Early trial of AMPK activator ATX-304 reports metabolic changes
An early phase 1b trial in people with obesity or prediabetes reported improvements in liver fat, visceral fat and resting metabolic rate after 8 weeks of taking the compound ATX-304.
Social media post claims aging shifts at ages 33, 60, 69 and 78
A social media post says a Nature Medicine article found 'aging waves' across 7 studies, around ages 33, 60, 69 and 78. This piece explains the idea and the questions it still leaves open.
Aging as a continuation of developmental programs: a hypothesis
A social media post presents a hypothesis by researcher João Pedro de Magalhães that aging may be developmental programs that become harmful after reproductive maturity.
Engineered enzyme reduced AGE damage in human tissue samples
A proof-of-concept study reported that an engineered enzyme removed advanced glycation end products from human tissue samples in the lab, lowering the damage to levels similar to those of a much younger person.
Mouse study suggests TBMS1 compound removes senescent cells
A Tsinghua University team reported, in mice, that the TBMS1 compound removes senescent cells by acting on the ATP1A1 protein, improving several age-related conditions.
Engineered enzyme reduces AGE damage in human tissue samples
A proof-of-concept study reports that an engineered enzyme removed AGEs, advanced glycation end products, from human tissue samples, including tissue from a 75-year-old donor.
Glutamate reduces aging skin cells in pre-clinical study
A report describes glutamate reducing senescent cells in experiments with skin cells. The author describes the work as entirely pre-clinical, meaning it is far from being tested in people.
Mouse study links senescent brain immune cells to brain aging
In aged mice, senescent immune cells built up in the brain's white matter. According to the report, targeting these cells reduced cells linked to inflammation. The finding comes from animals and does not yet tell us about people.
Nervous system imbalance as a possible starting driver of aging
A perspective published in the journal npj Aging proposes that chronic sympathetic dominance and lower parasympathetic tone may drive markers of aging. It is a theoretical hypothesis still under discussion.
