Public communication of sciences is of strategic relevance in the transition from the industrial society to the knowledge society. The Master’s Course in Scientific, Medical and Environmental Communication of Pompeu Fabra University in Barcelona (Spain) responds to this economic, social and cultural need. The result: professionals who clearly understand the key aspects of the transmission of scientific knowledge to society through the different essential communication channels in multiple organizations as, among others, mass media, institutional and public relations and museums. This initiative collaborates also to build informed and educated citizens, who understand, accompany and are able to participate in the necessary and unavoidable adaptation to this new society.
