Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not ...

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the ...

In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used ...

A fluorite crystal containing atoms of the radioactive element thorium-229. It was used to precisely measure the absorption spectrum of atomic nuclei at the National Metrology Institute of Germany ...

MIT researchers double the accuracy of optical atomic clocks by reducing quantum noise with an innovative laser technique.

Scientists are close to creating a nuclear clock—an ultra-accurate clock that uses a low-energy transition in the nucleus of a thorium-229 atom to keep time. Electrical interference makes atomic ...

For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It outweighs everything we see by a factor of five, yet it slips past every detector ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But scientists at MIT and Harvard have just taken precision to an entirely new ...

For nearly a century, scientists around the world have been searching for dark matter – an invisible substance believed to make up about 80 percent of the universe’s mass and needed to explain a ...
