Cracking open the proton

Physicists around the world are cracking open the proton, within the nucleus of the atom, to see what's inside.

A single proton can make a world of difference

Scientists from the RIKEN Nishina Center for Accelerator-Based Science and collaborators have shown that knocking out a single proton from a fluorine nucleus—transforming it into a neutron-rich isotope of oxygen—can have ...

A special elemental magic

A staple in every science classroom is the periodic table of elements, and for many it is their first introduction to the vast mysteries of the natural world.

Physicists test titanium target windows for particle beam

In the late 2020s, Fermilab will begin sending the world's most intense beam of neutrinos through Earth's crust to detectors in South Dakota for the international Deep Underground Neutrino Experiment, or DUNE. When the new ...

Watching single protons moving at water-solid interfaces

The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements. These protons occur naturally in water where a tiny proportion of H2O molecules separate spontaneously. Their amount ...
