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 analysis of nearly 3,000 older adults suggests that conscientiousness and openness may help the mind stay sharper than the body's biological clocks would predict — while neuroticism appears to do the opposite.
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 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 worm study suggests that mild stress in one generation can leave longevity marks on the next. The mechanism is fascinating — and the leap to humans is still a long one.
A new GeroScience analysis argues the machine-learning clocks behind today's biological-age tests optimize for math, not biology — and miss inflammation in the process.
Consumer biological-age tests promise a number that tells you how fast you're aging. A new analysis suggests the signal underneath that number isn't quite what we thought.
A new clinical clock called LinAge2 is trained to predict survival, not just guess your age — a quiet but meaningful shift for anyone paying for an epigenetic age test.
Transcriptomic clocks are joining PhenoAge and GrimAge in a fast-maturing toolkit — and early longitudinal work hints that ordinary medications may nudge the dial.
At-home longevity tests are graduating from gimmick to research-grade. Here's what second-generation DNA clocks and saliva-based oxidative stress assays actually measure — and what they still can't tell you.
