Treating Insomnia Changed an Epigenetic Aging Clock. Did People Actually Age More Slowly?
A randomized trial found that cognitive behavioural therapy for insomnia changed one epigenetic measure in older adults. The result is promising, but…
Does Caffeine Slow Aging? A New Study Finds an Intriguing Metabolic Signal
In 6,150 U.S. adults, higher caffeine exposure and a paraxanthine-to-caffeine ratio tracked with younger biological-age measures, less frailty and lower mortality. The…
A Probiotic Improved Healthspan in Old Mice. That Doesn’t Mean You Should Buy It Yet.
A bacterium depleted with age improved several health measures in old mice. Human intervention trials have not shown that it extends healthspan.
Does fasting become riskier with age? What a 15-year study actually found
A 15-year study linked longer daily meal gaps to faster disease accumulation in older adults, especially after age 78. Here’s what it…
Did NR Slow Muscle Aging While HIIT Sped It Up? What the Clock Study Really Found
A small exploratory human analysis found opposite shifts in muscle epigenetic clocks after NR and HIIT. It did not show that a…
Creatine for Healthy Aging: What the Evidence Actually Shows
Creatine may help older adults gain strength and lean tissue when paired with resistance training. Here is what the human evidence supports—and…
What Happened to Resveratrol, the Longevity Molecule That Was Everywhere?
Resveratrol moved from celebrated calorie-restriction mimetic to an instructive case study in the gap between animal biology and human longevity evidence.
A Wearable-Based Aging Clock Connects Daily Signals to Health Risk
Continuous pulse data may complement occasional clinic visits, but a wearable “age” is still a research biomarker, not a medical diagnosis.
