Researchers have combined theory and experiments to show that nuclear polarization does not limit studies of muonic atoms, clearing the way for new nuclear physics experiments. University of ...

Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's ...

Superfluid helium has produced a narrow muonium beam, opening a path to test whether exotic particles fall like ordinary matter.

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 ...

Clocks are the bedrock of modern physics and technology, as they allow scientists to assess fundamental scientific theories, and they make GPS and telecommunications possible. The current gold ...

Scientists using the STAR detector to study particle collisions at the Relativistic Heavy Ion Collider (RHIC) have found an intriguing dip in their data in a relatively unexplored region of the ...

Jericho celebrates its 20th anniversary with a nuclear physics audit: the CBS drama got electromagnetic pulse right, confirmed by a 1962 US nuclear test. But fallout cleared in hours, not weeks. The ...

Solving the nuclear many-body problem is a key challenge in nuclear physics – it deals with understanding the behavior of the protons and neutrons (called nucleons) inside atomic nuclei. These ...

Researchers have characterized the temperature-induced frequency shifts of a thorium-229 nuclear transition—an important step in establishing thorium clocks as next-generation frequency standards.

Nuclear physics investigates the properties, structure and reactions of atomic nuclei, the dense assemblies of protons and neutrons bound by the strong nuclear force. Central themes include the ...

Combining physics and generative AI creates novel, exquisitely active and selective molecules quickly and accurately, ...
