A widely prescribed blood pressure drug was associated with a 33% higher risk of serious kidney problems in people with type 2 diabetes, even when they were already taking kidney-protective medications. The surprising finding is prompting researchers ...

Researchers have built microscopic, light-driven robots that can rapidly navigate through liquid, collect bacteria, and deposit them in chosen locations. These tiny "cleaners" could open new possibilities for manipulating cells and microbes with ...

A newly discovered Arctic process can dramatically boost the number of particles that help form clouds. Near melting sea ice, sunlight reacts with chemicals released by the ocean, algae, and ice, causing cloud-seeding particles to multiply by as much ...

Traveling electrical waves sweeping across the brain may help determine what we notice, predict what comes next, and construct our internal picture of the world. Researchers now argue that these waves aren't just background activity--they could be a ...

A magnetar's colossal magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago, in which seemingly empty space alters the behavior of light. If confirmed, the discovery could offer the first direct evidence ...

Einstein's abandoned cosmological constant made a spectacular comeback when astronomers discovered that the universe's expansion is accelerating. It now sits at the heart of our best cosmological model--a model that works extraordinarily well, yet .. ...

Childhood criticism can leave people carrying a fear of failure long into adulthood, but new research suggests those emotional patterns may be surprisingly flexible. Young adults who revisited painful memories through imagery-based therapy showed ...

Kratom use and serious health problems linked to it have risen dramatically across the United States over the past decade. Poison center reports jumped from just 19 cases in 2010 to more than 1,200 in 2023, while severe outcomes--including life ...

Scientists studying three artisan British cheeses found that the microbes responsible for their distinctive flavors may also offer surprising benefits for gut health. As the cheeses matured, helpful bacteria transformed their aromas and textures ...

A low-fat vegan diet may help people lose weight without counting calories, shrinking portions, or feeling constantly hungry. In a 16-week clinical trial, people eating mostly fruits, vegetables, grains, and legumes consumed about 357 fewer calories ...
