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

Scientists have generated ultra-stable, donut-shaped light structures called skyrmions. These innovative beams can carry data ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

A research team from Munich has identified a previously unknown communication mechanism in harvestmen. Five closely related ...

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain—bypassing the body's ...

“Visible light is much gentler and can penetrate deeper, making it more suitable for real-world applications,” says Huaping Xu, a professor at Tsinghua University and one of the study’s corresponding ...

Spatial variation in lighting environments frequently leads to population variation in colour patterns, colour preferences and visual systems. Yet lighting conditions also vary diurnally, and many ...

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal ...

I am a versatile writer with a keen interest in exploring and sharing insights on lifestyle, food, and technology. With a deep curiosity about the world around me, I enjoy delving into various ...
