A modest increase in image quality was observed with polarized dermatoscopes vs ambient-light dermatoscopes for patient-performed teledermoscopy.

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard engineers ...

Almost a decade ago, Harvard engineers unveiled the world's first visible-spectrum metasurfaces—ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior ...

Astronomers have been puzzling over the origins of mysterious fast radio bursts (FRBs) since the first one was spotted in 2007. Researchers now have their first look at non-repeating FRBs, i.e., those ...

Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters and transforms inside real-world materials has long been treated as a black ...

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...
