An international team of researchers, led by JILA and NIST Fellow and University of Colorado Boulder Physics Professor Jun Ye and his team, has made significant strides in developing a groundbreaking timekeeping device known as a nuclear clock. Their results have been published in the cover article of Nature. 

Unlike traditional atomic clocks that rely on electron transitions, nuclear clocks harness the energy jumps within an atom's nucleus, offering the potential for unprecedented precision in measuring time. Using thorium-229 nuclei and advanced laser technology, the team has achieved key milestones, including the highest precision measurement of nuclear transitions to date.
