Shadowy dark matter has eluded scientists for decades. The LZ experiment may have spotted one particle, called a WIMP, but more data is needed to check.

Rubidium atoms on China’s Tiangong space station fell with the same acceleration, upholding a cornerstone of Einstein’s general theory of relativity.

There’s never been a good method to check for violations of the Outer Space Treaty’s prohibition of nuclear weapons in space.

Researchers were unsure whether alpha particles would aid or hinder fusion. Simulations suggest they help, by dampening turbulence.

First dreamed up decades ago, the world's first nuclear clocks are set to improve quickly, becoming more precise and aiding the hunt for dark matter.

Swapping materials in its Majorana 2 chip boosted the effectiveness of quantum bits that rely on the math of topology to reduce errors, Microsoft says.

Physicist Richard Feynman turned a lunch dilemma into a math problem. Researchers finally cracked his notes and found people approximate his solution on their own.

A mathematician found the most efficient way to fold paper into a doughnutlike shape.

Metals like copper oxidize — reacting with oxygen in the air — but gold doesn’t, thanks to a quick switch in atom arrangement on its surface.
