Women 55+ navigating menopause, bone, brain and heart health
Eleanor Voss writes about the science of women's health after 50 — menopause, bone density, brain and heart — cutting through decades of under-research with clear, candid evidence reviews. She writes the column she wished existed.

A Blood Test That Sees Alzheimer's Coming — Years Before Symptoms
A new analysis of plasma biomarkers suggests a simple blood draw may flag who is heading toward Alzheimer's while there is still time to act. The evidence is promising, not definitive.
Stress, Sleep, and the Fat Between Your Muscles: Three Studies on Aging Well
Three population studies point to the unglamorous middle layer of healthy aging — where perceived stress, sleep architecture, and muscle composition quietly shape what comes next.
Rapamycin vs. Metformin: What a New Vertebrate Meta-Analysis Actually Found
A 2025 analysis of 911 effect sizes asked which of longevity medicine's two favorite molecules truly mirrors dietary restriction. The answer reshuffles the conversation — carefully.
Measuring Biological Age: From PAI-1 to a Clinically Practical PCAge Score
Two 2025 papers move biological-age measurement closer to the clinic — one builds a risk score from routine bloodwork, the other names a druggable target in the aging heart.
Reversing the Decline: What the New Science Says About Aging Muscle
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.
Sex Differences in Cognition Don't Fade With Age — They Persist Into the 80s
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.
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.
The New Aging Hallmarks: Why Lysosomes, Senescent Cells, and Translation Errors Are the Next Frontier
Three 2025 papers are quietly reshaping the science of why we age — and where the next generation of interventions may aim. Here is what to know, and what to hold loosely.
The Centenarian Code: What Hypothalamic NPY, Spermidine, and Rare Gene Variants Reveal About Brain Aging
A new wave of 2025 research points to specific molecular levers that distinguish the brains of healthy agers from the rest — and hints at what the rest of us might one day borrow.
Rewriting the mTOR Aging Playbook: From YTHDF1 to Curcumin
Two new studies sharpen the picture of mTOR as an aging lever — pointing toward more precise ways to dial it down than blunt suppression.
Immune Resilience: The Aging Trait That Might Matter More Than Your Biomarkers
A new perspective in Aging Cell argues that the body's capacity to buffer immune decline — not the disease markers we obsess over — may be the truer measure of how well we age.
