A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

Inscribed on an Italian family’s 15th century coat of arms and decorating an ancient Japanese shrine, the Borromean rings are symbolically potent. Remove one ring from the trio of linked circles and ...

At the heart of every atomic nucleus, the strong interaction quietly dictates the structure of matter, yet for decades one of its simplest products refused to fit the script. The way fragile “light ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

Nuclear physics is a forbidding subject, even for trained physicists. To understand current news and discussion about nuclear science and technology, some background knowledge is required. The high ...

A researcher stands behind a metal pipe covered with electrical cords and gauges. A researcher works on a device at the Facility for Rare Isotope Beams. This part of the facility provides low-energy ...

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission ...

Here’s a mysterious truth that scientists have known since 1983: Protons and neutrons act differently when they’re inside an atom, versus floating freely through space. Specifically, the subatomic ...

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...
