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

At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic field. However, research by scientists led by Prof. Michal Tomza from the ...

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 ...

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 ...

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 ...

Light has no mass, but Europe's Large Hadron Collider (LHC) can convert light's energy into massive particles. Physicists studied matter-generating collisions of light and showed the departure angle ...

Ideas of high-energy particle physics have been borrowed for a device that might bring insight into fundamental questions of chemical physics — the molecular synchrotron. A whole number of ...
