Peaceful matter-antimatter pairing looks more real: The first signs of these Majorana fermions came last year in the form of a current that appeared at zero voltage in a nano-size wire...
They created a similar set-up but this time ramped the voltage up and down and shortened the wire. The plan was to cause the quantum waves associated with each fermion to overlap and constructively interfere, creating two extra peaks in current. Sure enough, the team saw two more blips...
