No one really knows what happens inside an atom. But two competing groups of scientists think they've figured it out. And both are racing to prove that their own vision is correct. Still, no one knows ...

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 ...

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, ...

Scientists have developed a new method that can help them probe inside atom’s nucleus. Developed by researchers at MIT, the method uses the atom’s own electrons as “messengers” within a molecule to ...
