A new GeroScience analysis finds women still outperform men on memory and executive function in their ninth decade — and estrogen plays a measurable, if partial, role.
A long-running English study suggests that persistent loneliness — not the occasional lonely week — quietly raises the odds of functional decline and earlier death. The signal is moderate, but it deserves a place alongside blood pressure and grip strength.
A new pathway analysis from the Long Life Family Study untangles how genes, school, and stimulating activities co-act to protect the aging brain — and what that means for the rest of us.
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 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.
