Science centres and museums can be considered a microcosm of the relationship between science and the public. Thus, it is of interest and importance to examine the evolution of science education and communication in the context of science centres and museums, as well as the implications for a more democratic model of science communication. Through exhibitions, films and educational programs, museums present science and technology in a specific light. Nowadays, museums are veritable wonderlands, where science and technology are accessible, increasing the level of enjoyment for the public. Are we to see this as a "happily-ever-after" for museums? Shall we endeavour to exclude the controversial and unresolved issues of scientific and technological research existing outside the territory of the museum, as these might interfere with the public's image of the museum as an "authority"? In response to the conference theme "The Museum at a Crossroads," this article aims to examine the political identity of the science museum as a public institution, as well as the challenges brought about by the changing dynamics of the science/society relationship. The European project of "Nanototouch" will also be discussed as a new model of science museum communication.
