Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

That all changed on Feb. 11, 1939, with a letter to the editor of Nature – a premier international scientific journal – that described exactly how such a thing could occur and even named it fission.

Neutron stars, the collapsed remnants of massive stars, hold the densest matter in the universe. These cosmic objects are ...

For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It outweighs everything we see by a factor of five, yet it slips past every detector ...

AMES, Iowa – John Lajoie, surrounded in his office by Star Trek posters and a few space hero action figures, recently made the case for nuclear physics research and the multi-million-dollar ...

Helen Jackson, a nuclear physicist with decades of experience and a patent under her belt, was excited about a new job at the U.S. Patent and Trademark office, a ...

UT researchers have made rare measurements of exotic nuclear decay that reshape how scientists think heavy elements form in extreme cosmic events. You can’t have gold without the decay of an atomic ...

A revolutionary achievement could pave the way for smaller, more efficient nuclear clocks. Last year, a research team led by UCLA achieved a milestone scientists had pursued for half a century. They s ...
