Physicists have found the strongest sign yet of a fabled four of a kind. For six decades, researchers have hunted for clusters of four neutrons called tetraneutrons. But evidence for their existence ...

Scientists have uncovered an unexpected breakdown of nuclear order in a remarkably symmetric atom, challenging long-standing ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

A team of physicists say they have created the first coherent picture of atomic nuclei from their composite particles, quarks and gluons. The 20th century was a pretty busy hundred years for particle ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

What would it actually be like if every particle in your body converted into a dark matter particle? And how long could you ...

Atoms can be more overweight than we thought, a team of scientists in the United States has discovered. They have sent atoms crashing into one another in a particle accelerator to create bloated ...
