Not this again..

BBC science reporting is iffy. Here they report that Majorana particles have been detected in the lab. Majorana was an eccentric physicist who disappeared mysteriously. He proposed a theory (unprovable at the time and still not completely ruled out) that a neutrino was its own anti-particle. The most promising way I know of to test this is to look for nuclear double-beta (2 electrons come out at once) decays and see if the electron's energy curve has the proper behavior at the endpoint--and that is notoriously difficult to do because it relies on knowing fine details about nuclear structure.

This isn't the same thing at all. This is a collective phenomenon, where a kind of wave of electrons in a metal can move around and act like it annihilates other waves of the same kind. This is cool and all--they can emulate Majorana behavior--but it isn't really a discovery of a fundamental particle. Good work, but the story is misleading...
