Throw some electrons onto the surface of a topological insulator and they seemingly become invincible, effortlessly bypassing obstructions along their route. Now researchers have crafted a structure that empowers particles of light to do the same thing. The first demonstration of a topological insulator for photons, reported April 10 in Nature,

“I think it’s wonderful,” says Michal Lipson,
