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.

Earlier this year, the Bulletin of the Atomic Scientists announced that it was moving the hands of the Doomsday Clock to 89 seconds before midnight, a symbolic hour signifying global catastrophe. The ...

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 ...

On this week’s “More To The Story,” Daniel Holz from the Bulletin of the Atomic Scientists discusses why the hands of the Doomsday Clock are the closest they’ve ever been 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.
