Scientists at the University of Groningen, led by Nobel laureate Ben Feringa and colleagues, have created a new porous ...

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 ...

Ultraviolet and near-infrared light are widely used in modern technologies but are invisible to the human eye. Researchers ...

Every star you see at night broadcasts its temperature through color, yet one shade sits permanently off the menu. The visible spectrum runs from deep red through orange, yellow, white, and blue, each ...

Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

How space telescopes capture distant galaxies using infrared imaging, precision optics, and astronomy technology beyond Earth's atmosphere.

A new, ultra-thin metasurface is making waves in the world of optics by defying the traditional behavior of light. By ...

T-shirts that warn of excessive sun exposure or labels that reveal damage to light sensitive materials: researchers at the ...

T-shirts that warn of excessive sun exposure or labels that reveal damage to light‑sensitive materials: researchers at the Technical University of Munich (TUM) have developed a coating that makes this ...
