Social isolation emerges as a key, independent risk factor for cognitive decline
Using longitudinal data from the US Health and Retirement Study, this study applied causal inference modeling to disentangle the independent and joint effects of social isolation and loneliness on later-life cognitive function. It shows that reducing social isolation is associated with modest but meaningful protection against cognitive decline, with loneliness mediating only a small proportion of this effect.

AI analysis of chest X-rays may reveal early signs of aging
Artificial intelligence may be able to reveal how fast your body is aging by analyzing a chest X-ray, according to a new study published in The Journals of Gerontology. Researchers found that a deep learning model was able to detect subtle, age-related changes in the heart, lungs, and overall health more effectively than leading DNA-based "epigenetic clocks."

Strong heart health lowers long-term death risk in cancer survivors
Higher Life’s Simple 7 cardiovascular health scores were associated with lower long-term all-cause and cancer mortality in cancer survivors from a large Italian cohort. Inflammation, resting heart rate, and vitamin D statistically explained a substantial share of these associations, supporting shared cardiometabolic pathways across cancer and cardiovascular disease.
