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 ...

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.

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

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 ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and ...

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

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...
