Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom. A new study comes closer than ever to ...

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.

Physicists with the STAR Collaboration have reported their strongest evidence yet for a long-sought feature in nuclear ...

Protons are 0.00000000000000003 meters smaller than we thought. That sounds like nothing, but it means one of these things must be true: Undiscovered particles are lurking, quantum mechanics needs ...

Since the discovery of radioactivity in the 19th century, humanity has been forced to reckon with an uncomfortable but sobering truth: much of the matter we find today will eventually decay away. This ...

Mirror magic: The "cores" of the exotic nuclei oxygen-22 and silicon-22 both resemble that of oxygen-16, with eight protons and eight neutrons. The neutron-rich oxygen isotope contains an additional ...

Protons make up most of the visible universe. Now, in a new study published in the August 18 issue of the journal Nature, scientists find that because of the strange nature of quantum physics, protons ...

A study led by the Institute for Bioengineering of Catalonia (IBEC) has revealed that protons and reactive oxygen species mediate long-distance charge transport in the mitochondrial respiratory chain ...
