“This research helps reveal how nuclear matter behaves under extreme conditions, like those that existed just after the Big ...

An international team of researchers recently measured the lifetime of a neutron outside of an atomic nucleus with extraordinary precision. By their measurements, the neutron survived for 14.629 ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Look around you (or, if you’re sight impaired, touch something). Everything solid, liquid, or gas that you see and feel is made of matter. We sometimes call it “normal” matter, though with dark matter ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable ...

Intriguingly, these scientists noticed that very particular numbers of protons and neutrons appeared to result in unusually stable nuclei, and these values became known as magic numbers. "The magic ...

Billions of times each minute, the Large Hadron Collider (LHC) smashes protons together, unleashing a maelstrom of energy that crystallizes into more protons, neutrons, and less familiar cousins of ...

Scientists are holding up a 'mirror' to protons and neutrons to learn more about the particles that build our visible universe. The MARATHON experiment has accessed new details about these particles' ...

Researchers from the Institute for Bioengineering of Catalonia (IBEC) and CIBER-BBN, in collaboration with teams from the ...
