Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

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 ...

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 ...

In use, lower light intensities favor more ordered crystalline regions, while higher intensities suppress crystallization, yielding softer, more transparent material. By projecting grayscale patterns ...

Apple in macOS Tahoe 26.2 introduced Edge Light, a clever new feature that turns your Mac's display into a virtual ring light during video calls. Instead of fumbling with external lighting equipment, ...

An evaluation of commercially available red light devices used to control myopia found that the devices exceeded established safety levels and may damage vision. The recommended duration for red light ...

Add Yahoo as a preferred source to see more of our stories on Google. Another day, another “feature” turned on in a load-bearing app that you might want to turn off. Fizkes / Getty Images For Gmail ...

Stephenson, MD, FACS, shares insights on evolving LAL technology and best practices for managing the ocular surface before ...

Artificial intelligence is prioritizing green lights for San Jose's buses - speeding them along their routes 20% faster, city ...

Control panels of a pre-digitalization nuclear plant look quite daunting, with countless dials, buttons and switches that all ...

Background To evaluate the efficacy and safety of repeated low-level red-light (RLRL) therapy for controlling myopia progression over 3 years in real-world settings. Methods This multicentre cohort ...
