Electrical resistance is easy to notice and hard to pin down. Power lines shed energy as heat, and metals warm up when ...

Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how ...

Hot on the heels of proving an 87-year-old prediction that matter can be generated directly from light, Rice University physicists and their colleagues have detailed how that process may impact future ...

Laser cooling and trapping allow physicists to map the dynamics of every ion-atom encounter in a collision experiment. For many years atomic-collision experiments basically involved measuring the ...

Heavy collisions Artist’s impression charged particle tracks streaming from a collision of two uranium nuclei overlaid on a sketch of the STAR detector at RHIC. The incoming uranium nuclei are shown ...

In a paper in Nature, the ALICE Collaboration 1 reports that data from high-energy collisions between protons can be used to investigate the little-understood nuclear forces between protons and ...
