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

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that can be bent, cloaked, and sculpted at scales smaller than a single wavelength ...

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Shaped quantum light is turning ordinary photons into powerful tools for the future of technology.

Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported the first ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
