Quantum weirdness could soon invade the living world, if a scheme to give a flu virus a strange double life comes off. The method might work on more complex life forms too. In quantum theory, a single object can be doing two different things at once. This so-called "superposition" is a delicate state, destroyed by any contact with the outside world. The largest objects that have been superposed so far are molecules. It is hard to put a much larger object such as a cat into a superposition. (source: newscientist.com)
