Capturing free-space optical light for high-speed Wi-Fi

Visible and infrared light can carry more data than radio waves, but has always been confined to a hard-wired, fiber-optic cable. Working with Facebook's Connectivity Lab, a Duke research team has now made a major advance ...

Electric cable bacteria breathe oxygen with unheard efficiency

Ten years ago, researchers at Aarhus University, Denmark, reported the discovery of centimeter-long cable bacteria, that live by conducting an electric current from one end to the other. Now the researchers document that ...

Putting on the pressure improves glass for fiber optics

Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these ...

Huge Puerto Rico radio telescope to close in blow to science

The National Science Foundation announced Thursday that it will close the huge telescope at the renowned Arecibo Observatory in Puerto Rico in a blow to scientists worldwide who depend on it to search for planets, asteroids ...

Cable failures endanger renowned Puerto Rico radio telescope

The giant, aging cables that support one of the world's largest single-dish radio telescopes are slowly unraveling in this U.S. territory, pushing an observatory renowned for its key role in astronomical discoveries to the ...

Researchers develop nonlinearity-induced topological insulator

Researchers from the University of Rostock have developed a novel type of nonlinear photonic circuitry in which intense light beams can define their own path and, in doing so, render themselves impervious to external perturbations. ...
