• Electron, heal thyself! Making curved electron beams go around barriers

  Electron beams, like light, spread out when they pass through an opening. Even highly focused beams such as lasers spread over large distances, a result of the wave character of light. However, by manipulating the wave form near its source, researchers can create something known as an Airy beam, which doesn’t disperse—and in fact follows…
