Nuclear and plasma physics form complementary pillars in our understanding of the fundamental forces and states of matter. Nuclear physics investigates the structure, dynamics and interactions of ...

Nuclear physics is the branch of science that examines the properties and behaviour of atomic nuclei, the densely packed assemblies of protons and neutrons held together by the strong interaction.

Matter is a lush tapestry, woven from a complex assortment of threads. Diverse subatomic particles weave together to fabricate the universe we inhabit. But a century ago, people believed that 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 ...

Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillon years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise ...

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision, new ...

Research using the world's most energetic laser has shed light on the properties of highly compressed matter -- essential to understanding the structure of giant planets and stars, and to develop ...

Nobel laureate Otto Hahn is credited with the discovery of nuclear fission. Fission is one of the most important discoveries of the 20th century, yet Hahn considered something else to be his best ...

In a four-part series, our podcast “Babbage” pulls back the curtain on the vast scientific infrastructure that America has created to build, maintain and upgrade its nuclear weapons. From the turn of ...

A tiny neutrino detector has found its footing in a fresh setting — at a nuclear reactor. Conventional detectors of the subatomic particles require metric tons of material. But the new detector has a ...
