Stretchable waveguides maintain stable transmission even when bent or twisted

Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These plasmonic waveguides could make it possible to seamlessly embed advanced sensing, communication and health monitoring functions into everyday wearable materials.

Researchers integrate waveguide physics into metasurfaces for advanced light control

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but many conventional designs are held back by inefficiencies. Typically, they rely on local resonances within individual nanostructures, which often leak energy or perform poorly at wide angles. These […]

How biological motors achieve maximum efficiency

Inside nearly every cell of your body, the tiny F1 motor works non-stop to create adenosine triphosphate (ATP), the universal energy source that powers almost every action you take—from breathing to running. While scientists have understood the structure of this molecular machine for years, a key mystery remained: how does its partner, the F0 motor, […]

Quantum uncertainty captured in real time using femtosecond light pulses

Researchers from the University of Arizona, working with an international team, have captured and controlled quantum uncertainty in real time using ultrafast pulses of light. Their discovery, published in the journal Light: Science & Applications, could lead to more secure communication and the development of ultrafast quantum optics.
