A “weekend warrior” approach to physical activity — getting 150 minutes of moderate-to-vigorous physical activity over one to two days instead of throughout the week — improved health and lowered the risk of death, finds a new study in the Journal of the American Heart Association.

Designed by University of Missouri researchers, the device includes AI technology to detect potential heart problems with over 90% accuracy, making it a promising tool for at-home monitoring.

Nuclear power plants keep their waste close by.

Buzzing insects may be seen as pests – but globally, hundreds of fly species migrate over long distances, with major benefits for people and nature, new research shows.

Spotted seals in some of the most remote marine areas around Alaska are consuming significant amounts of microplastics in their diets, according to a new University of Alaska Fairbanks–led study.

A new study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has found that children exposed to higher levels of air pollution in early and mid childhood have weaker connections between key brain regions.

While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes.

How much can our bodies adapt to a hotter and more humid planet?

Rice University researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS), commonly called “forever chemicals.”
