A long-running U.S. cohort study links weaker odor identification in older adults with later losses in balance, gait and grip — strengthening the case for smell as a low-cost biomarker of aging.
Two 2026 studies move the Med-Diet story from epidemiology toward mechanism, pointing to mitochondrial microproteins and a reshaped gut microbiota as plausible reasons the pattern protects the heart and brain.
A long-running German study finds that how old you feel tracks how your brain performs over time — at both the population and personal level. The signal is modest, but it's persistent.
A new Nature Medicine review argues that resilience — biological, psychological, social — is a measurable modifier of brain aging, and that studying it only in wealthy countries leaves real protection on the table.
New research in young adults links long-term obesity to measurable biological aging — and points to metabolism as the load-bearing pillar of longevity.
A 15,000-person cohort sharpens which fats in your bloodstream travel with healthspan — not just the years, but the years lived free of major disease.
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 445,000-person UK Biobank analysis suggests telomeres track life expectancy differently in men and women — and a transplant study links short, dysfunctional telomeres to frailty. Here is what that actually means for you.
Biological-age tests are flooding the longevity scene, but the rulers we use to measure aging — and the muscle loss that comes with it — are getting a hard second look.
A WHO-aligned way of thinking about reserves — and a simpler test of leg power — gives men past sixty practical handles on staying strong, sharp and independent.
