The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

The structure of the proton is under the microscope at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia, where a series of ...

An experiment more than 10 years in the making has delivered its first glimpse of the hurricane of particles whirring inside subatomic particles called neutrons, laying the groundwork to solve a ...

Review terms related to atomic structure. Have students make flash cards and quiz one another on terms related to atomic structure. For example, have them define such words as electron, proton, ...

Osaka - Understanding the behavior of proteins and enzymes is key to unlocking the secrets of biological processes. The atomic structures of proteins are generally investigated using X-ray ...

There are few things in the Universe that are as easy to form, in theory, as black holes are. Bring enough mass into a compact volume and it gets more and more difficult to gravitationally escape from ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...
