Flashes of femtosecond laser light, lasting just a few trillionths of a second, have made it possible to observe new magnetic ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

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 refraction ...

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 ...

Researchers have developed a new microscopy method that uses a magnetic field and polarized light to provide quantitative measurements that could enable faster and more objective detection of malaria ...
