The question of whether the electromagnetic waves emitted by living tissues contain information about those tissues is especially fascinating in brain emission.

Breakthrough ultrathin metalenses not only focus light like traditional lenses but also turn invisible light into visible light.

ETH Zurich develops ultrathin lens that converts infrared into visible light 03 Jun 2025 Based on LiNbO3 and nano patterning, the lenses have applications in tiny camera elements or banknote security.

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials.

Physicists at ETH Zurich have developed a lens with magic properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Contact lenses have enabled people to see beyond the visible light range, picking up flickers of infrared light even in the dark – or with their eyes closed.

Introduction: Recent findings show that visible light, particularly blue light, stimulates melanogenesis in human skin, though the underlying mechanisms remain debated. This study aimed to determine ...

Light therapy can also worsen melasma, a condition that causes blotches to form on the skin, Rogers says. Visible light, including red and blue, might also worsen hyperpigmentation or melasma for ...

"We choose these wavelengths because 1,550 nm, an infrared light, is commonly used for telecommunications, and 550 nm is visible light to which human eyes are highly sensitive.

Many people with a visible difference experience appearance concerns. Our study tested a novel approach for improving their body image.

In addition to “ doomscrolling,” toxic productivity from overwork and other psychological effects of spending too much time tapping away on a device, there’s more: our digital devices emit blue light, ...
