I'm aware of the definition of superconductivity. My point is that these researchers have no definitely found superconductivity, they have found evidence that under controlled conditions they can possibly achieve short-term high-temp superconductivity. This is a huge accomplishment, to be sure, but it's not as simple as "room-temperature superconductivity."
