But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental disturbances. According to new research, that dream might soon become reality ...

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

A clock built from thorium-229 has crossed an important line, from a long-discussed concept to a working device. The shift ...

As we scour and scorch the Earth for deeper wells of energy, investors and government agencies are pouring billions into ...

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 ...

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 ...

Recent advances in the optical spectroscopy of trapped atoms and ions have led to a measurement precision that is without peer in science 1, heading towards a relative accuracy of parts per billion ...

Atomic, molecular and optical (AMO) physics explores the quantum behaviour of electrons, atoms and light, and their mutual interactions across energy, length and time scales. In atoms and molecules, ...
