Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

With the terahertz scope, the team observed a frictionless “superfluid” of superconducting electrons that were collectively ...

Measuring conditions in volatile clouds of superheated gases known as plasmas is central to pursuing greater scientific ...

Technique lays the groundwork for neutral-atom quantum computers with more than 100 000 qubits, say physicists ...

Footpaths are designed for pedestrian safety, yet many remain dim or uncomfortable to use even when the nearby streetlights are functioning properly. This is a common urban problem. Pedestrians ...
