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 .. ...

Researchers have mapped the genetic risk of hemochromatosis across the UK and Ireland for the first time, uncovering striking hotspots in north-west Ireland and the Outer Hebrides. In some regions, around one in 60 people carry the high-risk gene ...

Living at high altitude appears to protect against diabetes, and scientists have finally discovered the reason. When oxygen levels drop, red blood cells switch into a new metabolic mode and absorb large amounts of glucose from the blood. This helps . ...

Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, potentially interfering with how they deliver ...

Scientists may have spotted a long-sought triplet superconductor -- a material that can transmit both electricity and electron spin with zero resistance. That ability could dramatically stabilize quantum computers while slashing their energy use. ...

Researchers tested whether generative AI could handle complex medical datasets as well as human experts. In some cases, the AI matched or outperformed teams that had spent months building prediction models. By generating usable analytical code from . ...

For the first time, scientists have mapped Uranus's upper atmosphere in three dimensions, tracking temperatures and charged particles up to 5,000 kilometers above the clouds. Webb's sharp vision revealed glowing auroral bands and unexpected dark ...

Astronomers have uncovered one of the most mysterious galaxies ever found -- a dim, ghostly object called CDG-2 that is almost entirely made of dark matter. Located 300 million light-years away in the Perseus galaxy cluster, it was discovered in an . ...

A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer's disease. Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell ...
