'Ghostly' neutrinos provide new path to study protons

Neutrinos are one of the most abundant particles in our universe, but they are notoriously difficult to detect and study: they don't have an electrical charge and have nearly no mass. They are often referred to as "ghost ...

Electrons set the stage for neutrino experiments

Neutrinos may be the key to finally solving a mystery of the origins of our matter-dominated universe, and preparations for two major, billion-dollar experiments are underway to reveal the particles' secrets. Now, a team ...

One step closer: Scientists help explain scarcity of anti-matter

A collaboration with major participation by physicists at the University of Wisconsin-Madison has made a precise measurement of elusive, nearly massless particles, and obtained a crucial hint as to why the universe is dominated ...

IceCube neutrino observatory nears completion

In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, which is located beneath the Antarctic ice -- will finally be completed after two decades of planning. In an article in the AIP's Review ...
