A feather discovered inside 66-million-year-old fossilized dinosaur poop may help explain why modern birds survived the asteroid catastrophe. The extinct bird it came from had more primitive insulating feathers, suggesting superior plumage may have hel…

Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. The findings suggest that keeping bedrooms darker could be an overlooked strategy for protecting the…

A major Ontario study found 24 common medication chains in which one drug’s side effects can be mistaken for a new medical problem, leading to another prescription. Researchers say closer medication reviews, pharmacist involvement, and automated alerts…

Scientists have created an ultra-small nanolaser that could eventually allow microchips to transmit information with light instead of electricity, potentially making computers faster while cutting energy use roughly in half. Thousands of the lasers cou…

Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of repeated control cycles down to just one. The advance could reduce errors and bring reliable, fault-tolerant quantum computers closer …

Britain’s wasps have become mysteriously scarce this summer, and scientists suspect an unusual combination of temperature swings, heatwaves, and food shortages may be responsible. Even the wasps that remain appear unusually small, potentially offering …

Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had nearly double the odds of constipation, 58% higher odds of irritable bowel syndrome, …

Unconventional quantum theories may imply that time itself has a tiny fundamental uncertainty, placing an ultimate limit on how precisely any clock could measure it. The effect is far beyond current detection, but it could reveal a hidden connection be…

A remarkably detailed study of Maria Branyas, who lived past 117, reveals that extreme longevity may involve both intense aging and powerful biological protection at the same time. Researchers found signs of advanced aging, but also low inflammation, b…

Researchers have shown for the first time that human heart muscle cells can regrow after a heart attack. The finding overturns the idea that damaged areas of the heart are completely incapable of regeneration. Scientists now hope to identify ways to dr…

Eating only between noon and 8 p.m. improved blood sugar control in a small study of adults with Type 1 diabetes and obesity, while avoiding an increase in serious complications. The promising findings offer the first evidence that time restricted eati…

Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found that some impacts create the familiar disk of debris that later becomes the Moon, wh…

UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a single dose controlled cancer and extended survival while avoiding a dangerous comp…
