Explore the mechanics behind the M1A2 Abrams battle tank, which moves 68 tons of steel with precision and power to hit targets 2 miles away. The smoke grenade launchers deploy grenades that emit smoke ...

Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different ...

As multicancer early detection research scales, generating sensitive and reproducible biomarker data across large studies remains a critical challenge. While advances in genomic and proteomic tools ...

Small home appliances equipped with electric heating coils and brushed DC motors, like hair dryers, air fryers and toasters—can emit harmful tiny ultrafine particles that deteriorate indoor air ...

Stephen Goff is the Higgins Professor of Biochemistry at Columbia University in New York City. He was a postdoc in Baltimore’s lab at the Massachusetts Institute of Technology in Cambridge from 1978 ...

Every electronic device in your home emits some form of radiation. But it's important to understand exactly what that means. When you hear "radiation," you might picture X-rays, radioactive materials, ...

Technological advances, such as digital screens, have their obvious benefits, but these advances often outpace the time it takes for human physiology to adapt to them. As more work, learning, and ...

Wastewater treatment plants emit far more greenhouse gases—especially methane and nitrous oxide—than previously estimated, significantly contributing to climate change. Researchers analyzed ...

Did you know that you’ve been glowing your whole life? No, you’re not bioluminescent like colorful jellyfish or bright fireflies, but you do emit a faint light that isn’t even visible to the naked eye ...

A new "optoexcitonic switch" already achieves state-of-the-art performance over current electronics and could serve as the basis for classical and quantum computing devices capable of operating at ...

Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal ...
