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 ...

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 ...

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 ...

The Isotope Separator On-Line facility (ISOLDE) directs a proton beam from the Proton Synchrotron Booster (PSB) onto ...

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 ...

Proton running for 2010 in the LHC at CERN came to a successful conclusion on November 4. Since the end of March, when the first collisions occurred at a total energy of 7 TeV, the machine and ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, ...

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 ...
