Publisher Correction: In situ nanocrystal confinement for efficient blue perovskite LEDs

Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered materials. The Nottingham Trent University team says the work will help fully optimize metasurface potential for a range of real-world applications and paves the way for a move from physical to virtual platforms in nanotechnology.

When people think of workplace segregation, they usually think of race or gender. Yet Americans are also sorted at work by something employers rarely measure: how they vote.

Australia is home to unusual mammals not found anywhere else—consider the platypus, Tasmanian devil or red kangaroo. But did you know our understanding of this continent's incredible mammalian diversity is still incomplete?
