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.

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

L-R: Dr Ashby Hilton, Dr Elizaveta (Liz) Klantsataya and Dr Sarah Watzdorf working on a prototype of a next-generation portable atomic clock. Time is almost up on the way we track each second of the ...
