Researchers found that moderate to severe periodontitis (gum disease) is associated with higher mortality risk, and this connection appears to work partly through accelerated biological aging—measured by two epigenetic clocks (PhenoAge and KDM). While biological …
Researchers used imaging in 285 macaques and postmortem human eyes to map how the retina thickens during development but thins with age—a pattern that could help us understand age-related vision loss. The findings suggest macaques …
Researchers experimentally warmed nests of wild great tits by 2°C during development and found the chicks showed accelerated telomere shortening—a cellular aging marker—despite normal growth. This suggests climate warming could speed up aging in birds, …
This narrative review examines whether three readily available blood markers—lymphopenia, neutrophilia, and the neutrophil-to-lymphocyte ratio (NLR)—can reliably indicate immune aging and predict severe COVID-19 outcomes in elderly patients. The authors conclude these markers consistently correlate …
Researchers found that people diagnosed with schizophrenia age faster on a biological level than the general population, using a novel brain imaging measure of aging. This finding, replicated across four independent datasets, could explain why …
This editorial discusses a new study finding that higher glutathione (an antioxidant) levels in the brain correlate with better cognitive performance in older adults, measured using brain imaging. However, the authors note that findings across …
An 8-week program combining diet, sleep, exercise, and stress management reversed biological age by an average of 3 years.
