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

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

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

A clock built from thorium-229 has crossed an important line, from a long-discussed concept to a working device. The shift ...

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.

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

New thorium-229-based time standard reaches 1-second drift in 3 million years and promises compact, robust optical clocks ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...

Without precise time, the modern world collapses - from GPS to the electricity grid. And Switzerland is one of the clock ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could exist in a quantum superposition, ticking both faster and slower at the same ...
