Are hidden chemicals making us fat? a new cause of obesity

Obesity is a growing problem all over the world. Since 1975, the number of overweight people has nearly tripled. We often blame high-fat food, sugar,...

Fingernail-sized sensor could detect hydrogen leaks in seconds

Hydrogen is often called the fuel of the future. It burns cleanly, leaving only water behind, and many countries are betting on it to power...

Oxygen defects reveal the secret of next-generation memory

The future of computing could be shaped by a new kind of memory called resistive random access memory, or ReRAM. Unlike traditional memory chips, ReRAM...

Scientists create greener materials to transform lighting and display technology

Lighting and display screens are everywhere—in our homes, offices, phones, computers, and even in medical devices. But the technology that powers them comes at a...

Scientists use bent crystals to steer particles toward new physics

Physicists at CERN have achieved a world first that could help unlock mysteries lying beyond our current understanding of particle physics. In a new proof-of-principle...

Scientists turn problem seaweed into greener building materials

Along coastlines in the Caribbean, the United States, and northern Brazil, massive amounts of brown seaweed called sargassum have become a growing problem. When it...

Scientists find cheap way to recycle lithium from old EV batteries

With millions of electric vehicles already on the road, one big question looms: what happens to all their used batteries? Even when a battery reaches...

Scientists find how to overcome the fatigue limit ceiling in ultra-strong steel

A Japanese research team has found a surprising way to make steel much tougher against repeated stress. Instead of weakening the metal, carefully applied “fatigue...

A magic-like material could make EV batteries easy to recycle

Electric vehicles (EVs) are on the rise, but there’s a hidden problem growing alongside them: waste. Every EV runs on large, complex lithium-ion batteries that...

Scientists find way to turn Mars soil into metal

The dream of building homes, labs, and entire settlements on Mars is no longer just the stuff of science fiction. Billionaires, space agencies, and space...
