Harry Potter fans, rejoice. A cloak of invisibility, like the one featured in the movies, is now a reality -- on a much smaller scale at least. Inventors have been working toward this for a while now, ...

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 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 ...

Lawrence Livermore National Laboratory (LLNL) engineers and scientists, in collaboration with Stanford University, have ...

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 ...

Metalenses -- flat surfaces that use nanostructures to focus light -- are poised to revolutionize everything from microscopy to cameras, sensors, and displays. But so far, most of the lenses have been ...
