Heart-Healthy Habits Slow the Epigenetic Clock — But Not All Equally
A new Korean cohort study ranks which of the eight cardiovascular health pillars move the biological-age needle most — and the answer differs by sex.

Your Biological Age May Be Loading the Dice on Your DNA
A new UK Biobank analysis suggests that how fast you're aging on the inside can amplify the genetic odds of diabetes and heart disease — and measuring both may sharpen the picture.

Epigenetic Clocks Hold Up Across Borders — and Your Habits Still Move the Needle
A new three-country study finds that the biological-age tests longevity fans love track smoking, heavy drinking, and BMI with surprising consistency. The catch? They only budge if your behavior does.

Measuring Biological Age: From PAI-1 to a Clinically Practical PCAge Score
Two 2025 papers move biological-age measurement closer to the clinic — one builds a risk score from routine bloodwork, the other names a druggable target in the aging heart.

Biological Age, Reimagined: What Bloodwork, mTOR, and New Biomarkers Can Actually Predict
A cluster of 2024–2025 papers is dragging biological-age science out of the speculative zone and into the realm of measurable prediction. The signal is real — but so are the caveats.

Why Your Biological Age Score Might Be Wrong
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.

Reading Organ Age in a Drop of Blood: What 44,000 Plasma Proteomes Tell Us About Living Longer
A massive new study suggests your body doesn't age all at once — and a single blood draw might one day map which organs are racing ahead.

Measuring How Old You Really Are: Biological-Age Clocks Get a Population-Scale Test
A 100,000-person Chinese validation shows phenotypic age scores can predict mortality reasonably well — and reminds us why the consumer versions still overreach.

Epigenetic Clocks Move From Lab to Lifespan: How Biological Age Now Predicts Real Health
A new wave of studies is validating molecular age clocks as practical predictors of kidney, cardiovascular and functional health — nudging longevity science out of theory and toward the clinic.

Epigenetic Clocks Have a Quiet Problem — and Maybe a New Opportunity
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.
