A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

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 ...

Adjusting the size and chemistry of nanocrystals within an ultrathin surface can speed up light-driven chemical reactions, ...

Researchers at the University of Waterloo have developed a system that allows humans to ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In August 2025, I wrote about Finchetto, a UK photonics startup working on an optical packet ...

A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of ...

All the info you need right here In this occasion I'll make a lighting system to be controlled remotely from my rc using Arduino compatible boards, they will take the input from a receiver and respond ...

In terms of physical controls, Google is mandating a power switch/button, touchpad (2), and camera button (3) on all Android XR glasses. Models with screens will also have a display button (1) that ...

A system developed by researchers at the University of Waterloo lets people collaborate with groups of robots to create works of art inspired by music. The new technology features multiple wheeled ...

Dear Heloise: To get more use out of discarded Christmas lights, I place a strand in a decorative container and leave them on at night as a night light. This is helpful when walking into a dark living ...

These days, multi-spot ceilings, downlights and LED panels are now the default, often installed with little thought beyond achieving maximum illumination. But lighting is so much more than that: many ...

The method involves stitching together many thin “slices” of light reflecting off an object.
