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 ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

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 ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a ...

Physicists at York University in Toronto have spent the last eight years meticulously conducting a sensitive experiment to measure the charge radius of the proton in hopes of resolving conflicting ...

Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimetre. This is precisely the ...

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 ...

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) ...

Physics is insane, and doesn’t always follow the laws we’ve formulated over the last several thousands of years of accrued observation and analysis. Case in point: a new study published today in ...
