Inside the most powerful particle colliders on Earth, protons slam together at nearly the speed of light, shredding matter ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...

GENEVA, Switzerland. - The world's largest atom smasher is back in action after more than a year of repairs and may be about to make big news. Officials in Switzerland say the Large Hadron Collider is ...

DEEP in the heart of every atom lurk protons, tiny particles from which the chemical elements were forged, first in the searing heat of the big bang and then in the nuclear furnaces of stars. The ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

Measurement in ordinary hydrogen agrees with a surprising 2010 result on the element's exotic cousin — but gives a smaller value than virtually every other experiment. The proton might truly be ...
