Chronic insomnia — trouble sleeping at least three days a week for three months or more — could speed up brain aging. People with chronic insomnia were 40% more likely to develop dementia or mild cognitive issues than people without insomnia. Insomnia with perceived reduced sleep was associated with lower cognition comparable to being four…

Tiny red objects spotted by NASA’s James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe — and may represent an entirely new class of celestial object: a black hole swallowing massive amounts of matter and spitting out light. Using the first datasets released by the telescope…

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately, this key characteristic of quantum mechanics defies the classical expectation that each particle should have a reality of its own, which gravely concerned…

Science News from research organizations Intriguing behavior of such electrons in particular materials produced by chemical synthesis. Date: September 13, 2025 Source: Ehime University Summary: Quantum materials, defined by their photon-like electrons, are opening new frontiers in material science. Researchers have synthesized organic compounds that display a universal magnetic behavior tied to a distinctive feature…

Approximately 30% of the global population is affected by metabolic-associated fatty liver disease (MASLD), a condition that previously lacked targeted treatments. In a groundbreaking discovery, researchers have identified a genetic factor that exacerbates the disease, and remarkably, the FDA-approved drug that most effectively targets this factor is vitamin B3. A collaborative research team led by…

A molecule made by bacteria in the gut can hitch a ride to the kidneys, where it sets off a chain reaction of inflammation, scarring and fibrosis — a serious complication of diabetes and a leading cause of kidney failure — according to a new study from researchers at the University of Illinois Urbana-Champaign and…

NASA’s Perseverance Rover spent three years exploring the floor of Jezero Crater, located just north of the Martian equator. This close-up look at what had previously been seen only from orbit revealed evidence of chemical reactions that shaped the planet billions of years ago. SETI Institute Senior Research Scientist Janice Bishop and University of Massachusetts…
