Experimenters guide heat around a two-dimensional object without leaving a trace.

The propagation of sound waves can be dramatically altered by forcing them to follow meandering channels, according to simulations.

Researchers have designed the first emitter of circularly polarized light made from a stand-alone semiconductor device.

Theorists propose that a nanostructured material could show what happens when the structure of spacetime changes, as some cosmologists have suggested may have occurred in the early universe.

A proposed structure blocks sound waves in one direction but lets them pass in the other direction by first doubling their frequency.

Researchers challenge the idea that special materials can bend light the ‘wrong’ way and create the perfect lens.
