Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei ...

Atomic clocks leveraged the atom to keep time, but new innovations will use the nucleus itself.

By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that ...

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.

Back in 2024, a joint collaboration of researchers from TU Wien in Austria and the National Institute of Standards and ...

(koto_feja/Getty Images) A breakthrough in chronometry decades in the making could redefine the limits of how we keep time.

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
