What Companion Dogs Are Teaching Us About Human Aging
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.

The Aging Brain Under Pressure: How Refined Diets and Dirty Air Quietly Speed Decline
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.

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.

Measuring Age Itself: The Quiet Revolution in How We Quantify Getting Older
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.

Metformin's Second Act: From Diabetes Pill to Longevity Candidate
A cheap, decades-old drug is being reframed as a possible geroprotective adjuvant. The science is intriguing — and still unfinished.

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.

Bones, Muscles, and the Frailty Cliff: What a New Aging Study Really Says
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.

The New Map of Aging: How Multiomics and Ribosome Biology Are Rewriting Longevity Science
A wave of 2025 research is pushing aging biology past single-pathway thinking — toward an integrated, system-level model that includes surprising new players like rRNA methylation and the slow failure of cellular recycling.

The CALERIE Receipts: A New Genomic Window Into How Caloric Restriction Shapes Human Aging
Researchers have released a multi-tissue genomic dataset from the only long-term randomized trial of caloric restriction in healthy adults. It won't tell you what to eat tomorrow — but it may finally show how eating less rewires the biology of getting older.
