Immune-Cell Patterns May Reveal How Well We Are Aging
A map of 12.4 million blood cells links the balance of two T-cell populations to health trajectories. The findings could inform future…
A Sardinian Village May Hold New Clues to Living Beyond 100
Validated records suggest unusually favorable recent survival among older women in Bolotana. Small numbers and changing estimates make it a candidate longevity…
What a 194-Year-Old Tortoise Could Teach Scientists About Longevity
Jonathan’s DNA offers clues involving repair, mitochondrial energy and gene regulation. A new tortoise study identifies hypotheses to test, without proving a…
Aging Blood Mutations Linked to Higher Serious Infection Risk
Analyses spanning 889,215 people linked clonal haematopoiesis to serious bacterial infections. Risk varied by mutation and clone size, and the observational findings…
A Newly Identified Form of p53 Helped Cells Enter Senescence
Researchers identified Δ246p53, a short protein form that responds to DNA damage and regulates p21 through p53-family interactions. The work is mechanistic…
Healthy Diets Linked to Distinct Blood Biomarkers in Older Adults
A Swedish study of 1,769 older adults linked diet-quality scores to selected metabolic, inflammatory and neurological markers. The cross-sectional results do not…
Restoring Cellular Cleanup Reduced Senescent Cells in Aged Mice
A Nature Aging study links a declining protein-cleanup pathway to failed immune clearance. An experimental activator reduced senescence-related changes in mice, but…
Which Aging Measures Are Most Strongly Linked to Mortality? A Study Compares 23
A peer-reviewed comparison in an older Scottish cohort found that brain, cognitive and physical measures carried powerful mortality information alongside molecular aging…
Senolytics Improved Liver Fibrosis in a Small Randomized Human Trial
A small randomized trial found improved liver fibrosis with dasatinib plus quercetin in people with MASH. The disease signal is encouraging, but…
FDA Officials Discuss How Longevity Drugs Could Be Evaluated
FDA officials at ARDD discussed possible evidence standards for longevity drugs. The conversation concerns regulatory science, not recognition of aging as a…
