Invisibility update:
Invisibility devices, long the realm of science fiction and fantasy, have moved closer after scientists engineered a material that can bend visible light around objects.

...It follows earlier work at Imperial College London that achieved similar results with microwaves. Like light, these are a form of electromagnetic radiation but their longer wave-length makes them far easier to manipulate. Achieving the same effect with visible light is a big advance.
