Glass nanostructures reflect nearly all visible light, challenging assumptions

New contact lenses give people infrared vision — even with their eyes shut. Sci-fi-style technology uses nanoparticles to convert infrared light into visible light that humans can see.

New window film drops temperature by 45 °F, slashes energy consumption | Assisted by quantum physics and machine learning, researchers have developed a transparent window coating that lets in visible light but blocks heat-producing UV and infrared.
