New analysis shows a way to self-propel subatomic particles

Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.

High-energy particle collisions reveal the unexpected

The nucleus of an atom is composed of protons and neutrons, which are themselves made up of elementary particles called quarks and gluons. Observing these elementary particles is difficult and typically involves smashing ...

Big chill sets in as RHIC physics heats up

If you think it's been cold outside this winter, that's nothing compared to the deep freeze setting in at the Relativistic Heavy Ion Collider (RHIC), the early-universe-recreating "atom smasher" at the U.S. Department of ...

Novel topological crystalline insulator shows mass appeal

Disrupting the symmetrical structure of a solid-state topological crystalline insulator creates mass in previously mass-less electrons and imparts an unexpected level of control in this nascent class of materials, an international ...

Catching graphene butterflies

Writing in Nature, a large international team led Dr Roman Gorbachev from The University of Manchester shows that, when graphene placed on top of insulating boron nitride, or 'white graphene', the electronic properties of ...
