Deep in the Arctic north, drained peatlands--once massive carbon vaults built over thousands of years--are quietly leaking greenhouse gases into the atmosphere. But new field research from northern Norway suggests there's a powerful way to slow that ...

Flea and tick medications trusted by pet owners worldwide may have an unexpected environmental cost. Scientists found that active ingredients from isoxazoline treatments pass into pet feces, exposing dung-feeding insects to toxic chemicals. These ...

Deep inside a Romanian ice cave, locked away in a 5,000-year-old layer of ice, scientists have uncovered a bacterium with a startling secret: it's resistant to many modern antibiotics. Despite predating the antibiotic era, this cold-loving microbe .. ...
