An exotic particle theorized more than 85 years ago has finally been discovered. Dubbed the "Weyl fermion", it is a strange but stable particle that has no mass, behaves as both matter and anti-matter inside a crystal, and is claimed to be able to create completely massless electrons. Scientists believe that this new particle may result in super-fast electronics and significant inroads into novel areas of quantum computing.
