Physicists have recreated the Nobel Prize–winning quantum Hall effect using light, revealing that photons can follow the same ...

In Sept. 2012, NASA’s Van Allen Probes observed the radiation belts around Earth had settled into a new configuration, separating into three belts instead of two. Scientists think the unusual physics ...

“Dark” electrons within solid materials may help us learn more about the behaviour of high-temperature superconductors, and perhaps solve other mysteries in material science. Most of a material’s ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...

Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 ...

Lightning formation and the conditions triggering it have long been shrouded in a cloud of mystery, but new research led by Penn State scientists is lifting the fog. Using mathematical calculations, ...
