Controlling brain neurons with light.The discovery leading to this technology was awarded the 2026 Nobel Prize in Physiology ...

In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

In recent experiments involving hydrogels and water droplets, researchers have proposed that exposure to visible light could ...

Newswise — At the upgraded Advanced Photon Source (APS), a powerful X-ray light source at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, new analysis capabilities are changing how ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...
