You probably think of matter and antimatter as mortal enemies, since their equivalent particles (such as protons and antiprotons) normally destroy each other on contact. However, there are now hints that the two might get along just fine in the right circumstances. Researchers claim to have successfully imaged a Majorana particle, which exists as both matter and antimatter at the same time. The team created it by placing a string of iron atoms on top of a lead superconductor, forming pairs of electrons and antielectrons -- except for one lone electron at the end of the chain, which exhibited properties of both.
