Researchers at the University of Sydney have developed a new type of radar that can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth ...

Nature may abhor a vacuum, but it sure loves structure. Complex, self-organized assemblies are found throughout the natural world, from double-helix DNA molecules to the photonic crystals that make ...

Structural colors result from interactions between light and nanostructures. Engineering structural colors is a promising, rapidly emerging research field. Compared with conventional painting ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have developed a new type of lidar—a laser-based remote-sensing instrument—that can observe cloud ...

Scientists at Duke University have created the first invisibility cloak that perfectly hides centimeter-scale objects. While invisibility cloaks have been created before, they have all reflected some ...
