A large UK Biobank analysis turns the abstract idea of cumulative physiological stress into a measurable signal — and links it, dose by dose, to how long we live.
A new analysis of more than 18,000 adults parses exercise by domain—and finds the clock-slowing benefits aren't distributed evenly. Sweat on your own time appears to matter more than sweat on the job.
A new study trained a machine-learning model on routine blood, urine and saliva tests from 11,554 people — and the labs already in your annual physical may carry more aging signal than the boutique clocks selling it back to you.
New 2025 population research points to surprisingly accessible markers — what's in your urine, the length of your reproductive years, and a single honest question about your health — that track biological age.
A seven-marker aging clock built on nearly 60,000 blood samples and machine-learning screens for natural geroprotectors hint at a clinic-ready future for longevity medicine — with caveats.
DNA-methylation clocks and a new atlas of immune aging are nudging longevity science from theory toward something a clinic could actually use. Here's where the evidence really stands.
A large NHANES analysis suggests the American Heart Association's updated checklist doesn't just predict heart trouble — it lines up with how fast your body is actually aging.
Chinese researchers built an early-stage 'aging clock' from amino acids, vitamins and oxidative-stress markers — a promising step toward biological age you might actually be able to nudge.
A new systematic review pools 17 plasma proteomics datasets into a shortlist of candidate proteins — the scaffolding for a next-generation aging clock that may one day rival DNA methylation.
Two fresh studies sharpen what 'biological age' actually measures — one tracing it to the air outside your window, the other to quiet patterns deep in the genome of people who reach 100.
