Atoms are the building blocks of matter. Everything around us — from air and water, to rocks, plants and animals — as well as everything within our bodies, is made up of atoms. They are very small, ...

Nuclear physicists used a little magic in their latest experiment conducted at the U.S. Department of Energy's Thomas ...

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 ...

A CSU team has measured a hydrogen proton’s radius to be 0.84 femtometers, resolving a long-standing scientific discrepancy ...

At long last, we have pinned down the size of a proton. More than 15 years after an experiment unexpectedly shook the world of particle physics, researchers are regaining their grip on one of this ...
