In a first, researchers from the U.S. and Germany excite Thorium-229 in opaque material, advancing optical nuclear clocks.

Old Dominion vs South Florida will broadcast nationally on ESPN for the Cure Bowl. Dave Neal and Fozzy Whittaker will call ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

Being on the surface of a sizable planet moving at high speed through space, spinning around a yellow star and on its axis, ...

What a play by Blake Horvath, who finds his top target in Eli Heidenreich for an 8-yard touchdown on fourth-and-goal. Navy ...

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 ...

We answered questions including, "Is there any collaboration between you guys and reporters from other cities?" and "How does ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...

The Hawks don't possess the puck much, yet they've managed to outscore their opposition so far this season. There's some luck ...

Physicists are quietly rewriting one of the most basic units in science, using a new generation of optical clocks that can ...

Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...
