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 new head-to-head validation of consumer sleep wearables and nearables shows where the devices earn their place on your nightstand — and where, especially after midlife, they quietly overreach.
A large Chinese cohort study suggests that losing both thinking power and lean mass together carries a sharper mortality signal than either alone — and points toward a combined training plan.
A rare two-decade study tracked how people react to everyday hassles — and found that the small stuff may slowly bend who we become.
A randomized crossover study put 27 older adults through three hours of sitting — broken up with single-task or dual-task walking. Cerebral blood flow and cognition shifted in ways worth dissecting.
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 analysis of more than 3,000 older Americans suggests that decades of weight patterns — not just today's number on the scale — interact with inherited obesity risk to nudge the body's biological clock forward.
A new study links handgrip, finger pinch, and even tongue strength to a blood marker tied to Alzheimer's pathology — hinting that simple bedside checks could one day flag risk early.
A pooled look at 33 studies finds microplastic exposure consistently nudges oxidative-stress markers upward. The signal is real — but so are the caveats.
A randomized trial of a self-managed balance app and new neuromechanics research are reshaping how we think about preventing falls in older adults — and why some topple backward like felled trees.
