Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth's climate. Scientists warn that this widespread deoxygenation is closely ...

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer's disease: the brain's own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, ...

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing ...

A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer's disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it ...

Scientists have redesigned zinc oxide particles to create a mineral sunscreen that protects against ultraviolet radiation without leaving such a noticeable white cast. The SPF 30 formula could make sunscreen easier and more appealing to use across a ...

Scientists are testing two promising ways to destroy PFAS, the stubborn "forever chemicals" that can accumulate in water and resist normal treatment. One method uses collapsing vapor bubbles to generate extreme heat and reactive molecules, while the ...

A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems. Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the ...

Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material ...

The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside ...

Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells from stress, inflammation, and damage. These ...
