I've been involved in UX design for nuclear power plants, air traffic control systems, gambling machines, and more recently lots of web sites. None was "science" but all were very important for their intended audience. I the case of the nuclear power plants and air traffic control systems, there was much more thought and analysis put in by user interface specialists, but I doubt that any of those specialists would consider themselves scientists or their practice a "science".
