For centuries, telescopes have relied on curved lenses and mirrors to capture images of the cosmos. While effective, these ...

Scientists have recently revealed, both theoretically and experimentally, that germanium atoms can arrange themselves into a 2D 'bitriangular' lattice on zirconium diboride thin films grown on ...

The first flat lens that works within a continual bandwidth of colors, from blue to green, has now been developed by researchers. This bandwidth, close to that of an LED, paves the way for new ...

For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be, the ...

A "radically different" flat map of the Earth has been produced by scientists who say it is more accurate than any previous 2D models that came before. The two-sided map is made up of two circles ...
