Protons are the basis of bioenergetics. We know them, in our everyday life, from the pH values we see on various soaps and lotions. But the ability to move them through biological systems is essential ...

Applying an electric potential causes a proton to transfer from a hydronium ion (at right) to an electrode's surface. Using electrodes with molecularly defined proton binding sites, MIT researchers ...

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 ...

Inside the nucleus of some atoms, protons appear to be doing very unexpected things. They are pairing up far more often than usual when they get extremely close to each other, and physicists don’t ...
