Nuclear power plants keep their waste close by.

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.

A combination of water management practices has contributed to notable groundwater gains in Central Arizona despite the region dealing with long-term water stress, according to a study led by researchers at The University of Texas at Austin and collaborators in Arizona and Colorado.

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.”

Don’t breathe in the dust on Mars.

From chronic respiratory problems to cardiovascular diseases, diabetes and dementia, health damage caused by particulate matter air pollution is wide-ranging and serious.

Distinguishing between rain and snow in near-freezing temperatures is a challenge, even with advanced methods.

Marine life in the deep ocean can take decades to recover from the impact of deep-sea mining for rare metals, new research shows.
