Researchers have recently identified 'dark electrons'—electrons undetectable using traditional spectroscopy—within solid materials. By examining palladium diselenide, the team ...

For the first time ever, scientists have turned light into a supersolid — a bizarre state of matter that acts both like a solid and a liquid (Science, March 5). Scientists achieved this feat ...

For the first time, researchers transformed light into a quantum crystalline structure to create a "supersolid" that's both ...
