A sweeping new scientific review suggests that pecans -- America's native nut -- may pack more heart power than many people realize. After analyzing over 20 years of research, scientists found consistent evidence that eating pecans can improve key .. ...

Chronic wounds often spiral out of control because oxygen can't reach the deepest layers of injured tissue. A new gel developed at UC Riverside delivers a continuous flow of oxygen right where it's needed most, using a tiny battery-powered system. In ...

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 ...

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 . ...

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 ...

Exercise may sharpen the mind by repairing the brain's protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In ...
