Sorbitol, a popular sugar-free sweetener, may not be as harmless as its label suggests. Researchers found it can be turned into fructose in the liver, triggering effects similar to regular sugar. Gut bacteria can neutralize some of it--but too much . ...

California researchers are preparing for the possible return of the New World screwworm, a parasitic fly that feeds on living flesh and once devastated U.S. livestock. By monitoring traps and educating veterinarians and farmers, they hope to stop the ...

A missing brain molecule may be disrupting neural wiring in Down syndrome, according to new research. Replacing it in adult mice rewired brain circuits and improved brain flexibility, challenging the idea that treatment must happen before birth.

Scientists at Northern Arizona University are developing a promising new way to detect Alzheimer's disease earlier than ever before--by tracking how the brain uses sugar. Using tiny particles in the blood called microvesicles, researchers may soon be ...

A mysterious cloud of ultra-hot dust around Kappa Tucanae A may finally have an explanation: a hidden companion star. The star's extreme orbit carries it straight through the dust zone, strongly suggesting it plays a key role in keeping the dust ...

People think online platforms are overflowing with toxic and misleading content, but the reality is far calmer. A small group of highly active users creates most of the harm, while the majority remain relatively civil. Still, many Americans assume .. ...

Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small brains. Changes in actin disrupted the orientation of early brain cell divisions, causing crucial progenitor cells to disappear ...

Over 8,000 years ago, early farming communities in northern Mesopotamia were already thinking mathematically--long before numbers were written down. By closely studying Halafian pottery, researchers uncovered floral and plant designs arranged with .. ...

A museum visit sparked a revelation when a Roman glass cup was turned around and its overlooked markings came into focus. These symbols, once dismissed as decoration, appear to be workshop identifiers used by teams of skilled artisans. The findings . ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These signals could help drive ion transport and ...
