New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...

Light beams of varying intensities (yellow cylinders) help visualize magnetic domains (light and dark areas), separated by domain walls (red lines). When something draws us in like a magnet, we take a ...

Imagine shining a flashlight into a material and watching the light bend backward – or in an entirely unexpected direction – as if defying the law of physics. This phenomenon, known as negative ...
