Researchers use gold nanoparticles to restore vision in mice, offering hope for treating retinal disorders like macular ...

Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices ...

Flashes of infrared light can detect signs of cancer in a patient's blood, new research suggests. In a new study, scientists demonstrated that a test using infrared light can detect the difference ...

But small enhancements can improve them even ... This unique structure allows it to manage light selectively. It allows infrared light (the main heat source) to escape while reflecting visible ...
