Abstract

Scientific knowledge is no longer transmitted solely through a one-way channel of communication from scientific communities to `lay' readers through the knowledge transmission `chain'. Communication between the two communities has now been extended into media and everyday social discourse where it crops up in news debates about issues such as public health and food safety. In this process, scientific academic discourse has lost much of its original form. This article examines part of the current research at the Centre de recherche sur les discours ordinaires et spécialisés. It provides evidence of new discursive forms adopted by science in media and social discourse, such as the emergence of enunciative standpoints, the redefinition of the role of the journalist as mediator between science and the general public, the use of specific forms of intertextuality and the interweaving of scientific elements in general social discussions. This research on new data implies renewed definitions of certain concepts used in linguistic descriptions: discursive meaning and signification, interdiscursive memory bank, etc. These recent forms of discourse have brought about a change in the status of science so that science has now become an object of debate in the public arena — a sign of its crucial social role.
