How fast is the universe expanding? The mystery endures

Scientists have known for decades that the universe is expanding, but research in the past few years has shaken up calculations on the speed of growth—raising tricky questions about theories of the cosmos.

New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction ...

Undergraduate engineers advance shock wave mitigation research

A team of undergraduate engineers at UC San Diego has discovered a method that could make materials more resilient against massive shocks such as earthquakes or explosions. The students, conducting research in the structural ...

JILA's novel atomic clock design offers 'tweezer' control

JILA physicists have demonstrated a novel atomic clock design that combines near-continuous operation with strong signals and high stability, features not previously found together in a single type of next-generation atomic ...

Students make neutrons dance beneath UC Berkeley campus

In an underground vault enclosed by six-foot concrete walls and accessed by a rolling, 25-ton concrete-and-steel door, University of California, Berkeley, students are making neutrons dance to a new tune: one better suited ...

Probing a nuclear clock transition

Modern atomic clocks are the most accurate measurement tools currently available. The best current instruments deviate by just one second in 30 billion years. However, even this extraordinary level of precision can be improved ...
