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 ...

Scientists have digitally reconstructed the face of a 1.5-million-year-old Homo erectus fossil from Ethiopia, uncovering an unexpectedly primitive appearance. While its braincase fits with classic Homo erectus, the face and teeth resemble much older ...

Ramanujan's elegant formulas for calculating pi, developed more than a century ago, have unexpectedly resurfaced at the heart of modern physics. Researchers at IISc discovered that the same mathematical structures behind these formulas also describe ...

Scientists are uncovering a surprising way to influence bacteria--not by killing them, but by changing how they communicate. Researchers studying oral bacteria found that disrupting chemical signals used in bacterial "conversations" can shift dental ...
