The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

Polarized light observations from ALMA reveal the magnetic structures and galactic outflows in Arp 220, the nearest ultraluminous infrared galaxy to Earth, providing detailed field maps.

A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...

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 ...

The COronal Diagnostic EXperiment (CODEX) is an externally occulted solar coronagraph designed to observe the linearly polarized K-corona to simultaneously measure the electron density, kinetic ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways. GOP members face backlash after ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

This spring, the Trump Administration cut the Consumer Financial Protection Bureau’s staff by about 80 percent, and Congress halved the agency’s budget cap. Last week, Democratic lawmakers urged the D ...

It's a beautiful summer day, and you're outside enjoying the weather. You are wearing your favorite sunglasses for protection from the bright sun. However, you still find yourself squinting when the ...
