The protons must first accelerate to about 60 percent of the speed of light, or around 114,000 miles per second. Only then can the stream of protons be tuned and focused on its target — a human tumor.

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 ...

All the focus on the LHC is generally on the enormous, 26km circumference of the main accelerator ring. But, according to Paul Collier, the head of CERN’s Beams Department, the protons that form the ...

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.

A number of advanced energy technologies—including fuel cells, electrolyzers, and an emerging class of low-power ...

When you get an MRI scan, the machine exploits a phenomenon called nuclear magnetic resonance (NMR). Certain kinds of atomic nuclei—including those of the hydrogen atoms in a water molecule—can be ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

The movement of protons through electrically charged water is one of the most fundamental processes in chemistry. It is evident in everything from eyesight to energy storage to rocket fuel — and ...
