By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that could lead to even more precise clocks and new ways to search for dark ...
A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

The world's first nuclear clocks are ticking, opening a new way to investigate dark matter and other mysteries of physics
For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons, the negatively charged particles that whiz around in an atom. Now, two ...
Nuclear clocks should be more robust and portable than the best available clocks today because nuclei are hard to perturb and are protected in a crystal. Creating a nuclear clock is “a dream come ...
For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based directly on the interactions between their protons and neutrons. Published in ...
Back in the 1930s, physicists were doing experiments involving what they called "beta decay." They observed that an element would suddenly spit out a fast-moving electron, and once it was done, it ...
The Department of Defense (DOD)—which is “using a secondary Department of War designation” under Executive Order 14347 dated September 5, 2025—is in the process of modernizing U.S. strategic nuclear ...
