The biology of aging, clinical translation and the hard work of separating a longer life from a longer claim.
New research complicates the assumption that cellular recycling uniformly declines with age. Its preliminary findings also highlight why measuring biological activity does not automatically establish a health benefit.
Researchers developed EHR-AGE using diagnosis histories from Hungary’s population records. The findings support further study of an accessible aging measure, while its value for clinical decisions remains unestablished.
A randomized study in older adults separates a biochemical response from evidence of functional benefit. The findings leave broader healthy-aging claims unresolved.
A small observational study linked faster epigenetic aging in participants in their forties to later everyday memory complaints. The study found no significant overall association across the sample and does not establish a dementia screening test.
A multi-cohort study connects menopause-related protein patterns with poorer cognitive outcomes in older women. The findings identify research candidates but do not establish a clinical screening test or a preventive treatment.
Newly published research links the metabolic supplement to smaller tumors in female mice and larger tumors in males in one experimental model. The findings underscore uncertainties about translating animal longevity research into human benefits.
Researchers linked Neisseria flavescens to aging-related profiles in people and tested it in worms and mice. The findings nominate a research candidate but do not establish a human longevity intervention.
Researchers mapped gene activity across 284 human brain donors, identifying distinct patterns across development, adulthood and aging. The findings provide a research reference but do not establish a treatment or a test of individual dementia risk.
An observational analysis of 2,418 adults connects long-term employment patterns with later cognitive performance. The findings do not establish that postponing retirement prevents dementia.
A longitudinal analysis connects lower bone density with cognitive decline and regional brain changes. The findings suggest shared aging vulnerabilities, but do not establish that treating bone loss protects cognition.
A new imaging study connects cellular chemistry with gene activity in aging mouse lung and skin. The approach could improve research on senescence, but human diagnostic use remains unvalidated.
New research examines how mitochondrial stress affects the hippocampus. The findings add to animal evidence that biological sex influences vulnerability to brain aging.
A new research toolkit compares AI systems across biological datasets and introduces compact models trained for aging research. Its benchmark results support further computational testing but establish no clinical or longevity benefit.
A study of 95,559 UK Biobank participants links estimated sleep stages and duration to subsequent diagnoses. The observational findings do not establish that changing a sleep-stage score prevents illness.
University researchers are recruiting women ages 50–75 to evaluate a remote exercise and nutrition program. The study will examine feasibility and sarcopenia-related outcomes; clinical benefits remain unestablished.
A new framework draws on mouse research to identify biological signals that might help prioritize longevity interventions. The proposed markers still need validation before they can establish treatment benefits in people.
A new study tests separate biological-aging models for females and males across organ systems. The findings raise questions about how aging scores should be interpreted in prevention research.
Researchers found associations between healthier dietary patterns and more favorable molecular aging measures. The observational study does not establish that changing diets slows aging or extends life.
The initiative will develop computational models of hormone regulation across the lifespan. Its relevance to healthy aging lies in improving research on treatment response and toxicity, with clinical benefits still untested.
Researchers catalogued 1,067 small proteins missing from a reviewed reference database and linked one to mitochondrial function in laboratory microglia. The findings expand Alzheimer’s research tools, while leaving treatment and prevention benefits untested.
