Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...

Although the study was small, it demonstrates that polarized light imaging can detect structural signatures of EDS in unstained biopsy samples, and it may even differentiate hEDS from cEDS and healthy ...

Ehlers–Danlos syndromes (EDS) are inherited conditions that affect the body’s connective tissue, which provides strength and ...

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 ...

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it.

Microscopy is an imaging technique that enables us to see a world that would otherwise be invisible to us. Once upon a time, visualizing cells, microbes and other entities not perceptible to the naked ...

A device produces green light while a researcher in lab gear stands in the background. This OLED device, which is held by a mechanical support, is producing circularly polarized light. Credit: ...

Who doesn’t know the problem of glare when trying to ogle a PCB underneath a microscope of some description? Even with a ring light, you find yourself struggling to make out fine detail such as ...

Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and ...
