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

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 ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental ...

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

For many years, scientists all around the world have been working towards this goal, now suddenly things are happening very fast: it was only in April that a team led by Prof Thorsten Schumm (TU Wien, ...

A clock based on radioactive thorium atoms realises a long-held ambition, demonstrating a technology that could eventually ...

The timekeeping device is made with atomic nuclei of thorium, although it is not yet more precise than standard atomic clocks. Reading time 2 minutes Meet the “nuclear” clock: a device that marks the ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.
