(PhysOrg.com) -- Taking light control to a new level, scientists have proposed a technique for confining light into an area just 1/500th the size of the light's wavelength. Since funneling light through such tiny spaces enhances ...
Three years ago, the first ever image of a black hole stunned the world. A black pit of nothingness enclosed by a fiery ring of light. That iconic image of the black hole at the center of galaxy Messier 87 came into focus ...

Two researchers, one with Biofaction in Austria, the other with Université de Toulouse in France, report an example of ants (Azteca brevis) in Costa Rica who have developed a truly unique way of capturing prey that are much ...
(Phys.org)—A team of researchers from China and the U.S. has devised a relatively simple means for measuring the shear forces that exist between sheets of graphene and other materials. In their paper published in the journal ...
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility of weaving together ...
