Researchers turn light upside down

Researchers from CIC nanoGUNE (San Sebastian, Spain) and collaborators have reported in Science the development of a so-called hyperbolic metasurface on which light propagates with completely reshaped wafefronts. This scientific ...

Wi-fi on rays of light—100 times faster, and never overloaded

Slow wi-fi is a source of irritation that nearly everyone experiences. Wireless devices in the home consume ever more data, and it's only growing, and congesting the wi-fi network. Researchers at Eindhoven University of Technology ...

A smarter way to make ultraviolet light beams

Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve ...

Graphene may open the gate to future terahertz technologies

Nestled between radio waves and infrared light is the terahertz (THz) portion of the electromagnetic spectrum. By adding a nanoscale bit of graphene, researchers have found a better way to tune radiation for a THz transmitter.

Dawn beams back asteroid science data

(PhysOrg.com) -- The Dawn spacecraft has completed a graceful spiral into the first of four planned science orbits during the spacecraft's yearlong visit to Vesta. The spacecraft started taking detailed observations on Aug. ...
