Public Communication of Science and Technology plays a relevant role in today’s ‘Societies of Knowledge’ not only in the dissemination of theories and innovations but also because it contributes to shape a scientific culture (López Cerezo, 2005). For this reason, it is of interest for the studies on Communication as well as for the studies on Sociology and Philosophy of Sciences. In this field, we focus on the use of metaphors and their cognitive reach. Our hypothesis is that metaphor is not merely an instrument for didactic or communicational purposes, but it has the capacity to produce new meanings and to reinforce existing meanings in the wider cultural frame. In this paper, we shall focus on the metaphors the digital press habitually uses to refer to the sciences. These metaphors contribute to the consolidation of a public image of the sciences, of scientists and of their activity. Based on recent theories on metaphors and the communication of sciences (Lizcano, 2009; Palma, 2012), we put forward an analysis of news and editorials that recur to metaphors such as “impact”, “struggle”, and “endeavor”. We also make some reflections on the meanings they produce, the image or science they produce and the resulting image of science. We shall argue that these metaphors are more frequent than would be expected. Also, they produce an image that ponders sciences as a privileged form of knowledge and promotes a kind of relationship in which society lacks the relevance required by a critical scientific culture.
