Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

The molecular hydrogen ion H₂⁺ is the simplest molecule. This simplicity makes it a perfect study object for physicists, as ...

The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

The ProBE linac will accelerate protons from a medical cyclotron to the higher energies required for proton imaging. (Courtesy: Joel Sauza Bedolla) The recent meeting, Physics-based Contributions to ...

For almost a decade, physicists have been baffled by the so-called proton radium puzzle: using different methods of measurement, they obtained two numbers that are slightly yet significantly different ...

WASHINGTON, D.C., July 20, 2009 -- Proton therapy -- which uses beams of the subatomic particles to treat cancer -- is a hot topic at this year's American Association of Physicists in Medicine (AAPM) ...

Protons can surf some truly gnarly waves. A new experiment suggests that the subatomic particles can be accelerated by a process akin to surfers catching waves. The protons get a speed boost not from ...

How big is a proton? This doesn't sound like a very complicated question, but it's one that turned out to have the potential to wreck a lot of modern physics. That's because different methods of ...
