The thorium-229 nuclear clock offers an exciting new possibility, enabling researchers to spot the faintest deviations in resonance frequencies that could indicate the presence of dark matter.

Scientists believe that if a nuclear clock is developed—one that uses the atomic nucleus to measure time with extreme precision—even the tiniest irregularities in its ticking could reveal dark ...

WASHINGTON — The United States is rushing to put nuclear power reactors on the Moon and Mars, and hopes to launch the first ...

The risk of nuclear war and the threat of climate change have caused the Bulletin of the Atomic Scientists to move the Doomsday Clock 30 seconds closer to catastrophe to two minutes to midnight.

However, progress on the nuclear clock stalled at the very first stage, when scientists tried to measure the resonance frequency of thorium-229 with the utmost precision.
