An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

What happens when the smallest building blocks of matter refuse to play by the rules of traditional physics? For decades, ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses. They definitely exist in East Lansing, Michigan.

Far lighter than other ions collided at the LHC, oxygen (and neon) could tell us about conditions in the early universe.

THE neutron is usually looked upon as an aggregate of a proton and an electron. If it were so, there ought to be a strong tendency for hydrogen atoms to be converted spontaneously into neutrons ...

Protons and neutrons also have another property — kind of like a different type of charge — that is strong enough to bind them together once they are able to get very close together.

In a study published in Physical Review Letters, scientists at GSI Helmholtzzentrum für Schwerionenforschung have discovered ...

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...

Scientists from CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to ...
