A 2025 review reframes sarcopenia as a modifiable condition — and grades which interventions actually move the needle on muscle mass, fiber loss, and motor unit decline.
A sweeping new analysis across 23 high-income countries says the steady climb in lifespan is losing steam. Here's what that actually means for the choices you make now.
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 2025 review argues that AI-augmented CPET — measuring how your heart, lungs and metabolism work together — should replace the classic stress ECG as the default deep evaluation. Here is what that shift actually means for your calendar.
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.
