Every Story. Every Angle. Everywhere.
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…
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.…
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…
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…
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…
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…
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…
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…
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.…
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…
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…
Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA…
Scientists have used DNA from living descendants to identify four more members of the doomed Franklin expedition, including Harry Peglar, whose identity had remained uncertain for 166 years. The findings…
Researchers have created a foam-based material that produces intense whiteness and water repellency without titanium dioxide pigments or PFAS chemicals. Inspired by natural structures in snow, clouds, flowers, and lotus…
While clearing debris to protect ancient Egyptian tombs from flash floods, researchers near Luxor stumbled upon an unknown 3,000-year-old tomb. Its remarkably preserved paintings depict an official named Paser, his…
