Small AI Models Led an Aging-Biology Benchmark. What Does That Actually Mean?
A compact model led LongevityBench, a new test of AI on aging data. The gains are real, but benchmark rankings and proposed…
Aging May Leave More Than One Kind of Signature in Our DNA
In 1,445 Canadian adults, DNA methylation variability revealed signals that averages alone missed. A combined biomarker remains experimental and is not a…
Scientists Want a Speedometer for Aging. These 12 Signals Could Be the Start
Researchers propose 12 biological signals that might reveal whether aging is currently moving faster or slower. The candidates come mostly from mouse…
How Diet and Microbes Unlocked a Longevity Pathway in Worms
A worm study connects bacterial nutrients, RICTOR and mitochondrial cleanup. It provides no evidence that supplements extend human lifespan.
She Lived to 117. Her Biology Shows That Aging and Disease Are Not Quite the Same Thing
Maria Branyas carried clear molecular signs of extreme age alongside low inflammatory markers and other features associated with good health. Her detailed…
Scientists Found One of the Body’s Natural Brakes on Inflammation
A small human study traced a fat-derived signaling pathway that limited inflammatory immune cells and hastened pain resolution. It did not test…
Higher Folate Tracked With Slower Biological Aging. That Does Not Mean Supplements Slow Aging.
In older adults from India, higher folate tracked with slower biological aging while higher homocysteine tracked with faster aging. The longitudinal study…
Cash Payments Changed an Epigenetic Aging Measure in Children. What Does That Mean?
A randomized cash-transfer trial changed one epigenetic aging measure in four-year-old children. The finding is intriguing, but it does not prove that…
Your Gut Microbiome May Track Inflammaging Better Than Your Age
In 1,199 adults, gut microbiome composition tracked inflammatory and physiological differences more strongly than chronological age. The study is observational and does…
Six Biological Age Clocks Moved Younger After an AI-Designed Drug. Did Aging Actually Slow?
Rentosertib lowered predicted biological age across six protein-based clocks in a small pulmonary fibrosis trial. The result is intriguing, but it does…
