Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

A string of experiments using thorium-229 nuclei has brought the long-theorized nuclear clock closer to reality, producing frequency measurements stable enough to challenge the atomic clocks that ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

Physicists have developed a highly precise and ultra-sensitive atomic clock based on ytterbium, which ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...

Add Yahoo as a preferred source to see more of our stories on Google. Jon Wolfsthal, director of global risk at the Federation of American Scientists (FAS), Asha George, executive director of the ...

Researchers from Los Angeles, Munich, and Mainz open new avenues for nucleus-based quantum technologies A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian ...

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.
