Scientists found that older, weaker muscle releases fewer extracellular vesicles and less of a microRNA called miR-7a-5p. Exercise can restore vesicle release and may help reduce cancer risk in older adults. The work suggests new biomarkers and therapies.

A study of sexual and gender minority (SGM) young adults found hiding identity linked to more emotional strain, while being open related to clearer self‑feeling and more positive identity emotions. Researchers tracked daily experiences over several days.
A 12-year study in southwest Tanzania found that mass treatment for lymphatic filariasis (elephantiasis) was linked to fewer new HIV infections. Researchers say clearing the parasite may reduce HIV risk, but policies have not changed.
A global study finds billions of people live in "cooling poverty" as hot spells become more frequent and intense. Researchers call for low-cost, coordinated policies across housing, water, health and cities because air conditioning alone is not enough.
Researchers found that a common eight-question depression test gives similar results for people with and without chronic pain. The study used a large 2019 US health survey and says clinicians can trust positive screens in patients with pain.
