Stars are powered by nuclear fusion, in which two or more atomic nuclei have a close encounter and form one or more different nuclei 1. A key aspect of nuclear fusion is that the rearrangement of ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

All the matter we know of in the Universe is made up of Standard Model particles. Photons and neutrinos zip through the Universe all the time, far outnumbering all the other particles. Normal, ...

Quarks, the elementary particles that make up protons and neutrons, have been notoriously difficult to nail down -- much less weigh -- until now. A research group has calculated, with a razor-thin ...

Deep within the atoms that make up our bodies and even within the protons and neutrons that make up atomic nuclei, are tiny particles called quarks. When you purchase through links on our site, we may ...

Nature is the ultimate puzzle player, as scientists at the European Center for Nuclear Research (CERN) found out last week. In the late 1950s, particle physics was in crisis. Being the branch of ...
