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

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, ...

Physicists at MIT have developed a new way to probe inside an atom's nucleus, using the atom's own electrons as "messengers" within a molecule. Typically, experiments to probe the inside of atomic ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

A researcher stands behind a metal pipe covered with electrical cords and gauges. A researcher works on a device at the Facility for Rare Isotope Beams. This part of the facility provides low-energy ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...
