By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that ...

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental ...

Jefferson Lab, a nuclear physics research lab, broke ground on a 30,000 sq ft (2,787 sqm) data center last Friday.

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, ...

First dreamed up decades ago, the world's first nuclear clocks are set to improve quickly, becoming more precise and aiding ...

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) usually capture what happens when ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...
