Scientists watching a new fluorescent sensor inside Alzheimer's-model mouse neurons spotted a quieter fuel crisis — and a possible way to refill the tank.
The Dog Aging Project's Precision Cohort turns 1,000 family pets into a living laboratory for geroscience — and a useful mirror for the rest of us.
Two 2025 studies sharpen an uncomfortable idea: what we eat and what we breathe may be shaping the aging brain as forcefully as the genes we inherit.
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.
Two new papers — a framework for what a real aging biomarker must do, and a label-free way to read it inside mitochondria — suggest biological age is finally becoming measurable science.
A major European Heart Journal review reframes excess weight as a driver of the heart's biological aging itself. The implication: weight reduction may be less about preventing one bad day and more about extending healthy years.
A cheap, decades-old drug is being reframed as a possible geroprotective adjuvant. The science is intriguing — and still unfinished.
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.
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.
A long-running Taiwanese cohort took a closer look at osteosarcopenia — losing bone and muscle at the same time — and the findings are more nuanced than the headlines suggest.
