A new study suggests that the positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects. Neutron stars are the smallest, densest ...

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 ...

Adding a single proton to a doubly magic isotope of oxygen is enough to significantly alter its properties, an international team of physicists has discovered. Led by Tsz Leung Tang at the University ...

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.

The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty years ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

The finding could be put to use at a new facility opening in 2020 that might create new elements—that is, nuclei with more than 118 protons—in addition to new isotopes of the known elements Scientists ...

A few days ago I wrote about how different measurements of the Hubble parameter gave results that didn't quite agree. It's not the only example of such an experimental disagreement. In fact, one of ...

For four years, James Chadwick was a prisoner of war in Germany. When World War I ended, he returned to his native England to rejoin the mentor of his undergraduate days, Ernest Rutherford. Now head ...
