As several recent National Academies of Sciences reports have highlighted, greater science communication research is needed on 1) communicating chemistry, and 2) building research-practice partnerships to advance communication across science issues. Here we report our insights in both areas, gathered from a multi-year collaboration to advance our understanding of how to communicate about chemistry with the public. Researchers and practitioners from science museums across the U.S. partnered with academic social scientists in science communication to develop and conduct multi-strand data collections on chemistry communication and informal education. Our focus was on increasing interest in, the perceived relevance of, and self-efficacy concerning chemistry through hands-on activities and connecting chemistry to broader themes concerning everyday life and societal impacts. We outline challenges and benefits of the project that future collaborations can gain from and illustrate how our strands of work complemented each other to create a more complete picture of public perceptions of chemistry.

When, to what extent and under what conditions autonomous driving will become common practice depends not only on the level of technical development but also on social acceptance. Therefore, the rapid development of autonomous driving systems raises the question of how the public perceives this technology. As the mass media are regarded as the main source of information for the lay audience, the news coverage is assumed to affect public opinion. The mass media are also frequently criticized for their inaccurate and biased news coverage. Against this backdrop, we conducted a content analysis of the news coverage of autonomous driving in five leading German newspapers. Findings show that media reporting on autonomous driving is not very detailed. They also indicate a slight positive bias in the balance of arguments and tonality. However, as soon as an accident involving an autonomous vehicle occurs, the frequency of reporting, as well as the extent of negativity and detail increase. We conclude that well-informed public opinion requires more differentiated reporting — irrespective of accidents.

Little is known about how incidental exposure to news, interpersonal discussion, and the diversity of social networks interact in social media environments and for science-related issues. Using a U.S. nationally representative survey, we investigate how these features relate to factual knowledge of gene editing. Incidental exposure to science-related news interacts with interpersonal discussion and network heterogeneity and reveals that the relationship between incidental exposure to news and knowledge is strongest among those who discuss the least. Incidental exposure could alleviate knowledge gaps between the Facebook users who are the most and least involved in interpersonal discussions about science.

Communities of practice in science communication can make important contributions to public engagement with science but are under-researched. In this article, we look at the perspectives of a community of practice in astronomy communication regarding (relations with) their public(s). Most participants in this study consider that public(s) have several deficits and vulnerabilities. Moreover, practitioners have little to no contact with (and therefore make no use of) academic research on science communication. We argue that collaboration between science communication researchers and practitioners could benefit the science-public relationship and that communities of practice may be critical to that purpose.

When analysing the actors of the science communication ecosystem, scholarly research has focused on the perceptions and attitudes of scientists, science journalists, and science communicators. How the public envisages the roles of science producers and mediators is mostly uncharted territory. We address this gap, by examining the results of a public consultation in Portugal concerning science communication. We show that the public demonstrates a clear preference for science communication performed by scientists, over journalists, although credibility and trust depend on multiple factors. We also ascertain that professional science communicators are mostly invisible, though the public recognises the value of `translators'.

European science communication project QUEST surveyed and reviewed different aspects of European science communication, including science journalism, teaching and training in science communication, social media activity, and science in museums. This article draws together themes that collectively emerge from this research to present an overview of key issues in science communication across Europe. We discuss four central dynamics — fragmentation within research and practice; a landscape in transition; the importance of format and context; and the dominance of critical and dialogic approaches as best practice — and illustrate these with empirical material from across our datasets. In closing we reflect upon the implications of this summary of European science communication.

Internet technologies and specifically social media have drastically changed science communication. The public no longer merely consume science-related information but participate (for example, by rating and disseminating) and generate their own content. Likewise, scientists are no longer dependent on journalists as gatekeepers to spreading relevant information. This paper identifies and reflects on relevant theoretical strands that help to inform theoretical frameworks and research agendas. Therefore, we discuss the technological structures and resulting affordances, a new knowledge order and its actors, as well as trust and rationality as important constructs.

This paper investigates the dimensions of trust and the role of information sources and channels in developing differentiated forms of science communication. The discussions from two public consultations carried out in Italy and Slovakia about controversial science-related topics were quali-quantitatively content analysed. The results show that scientific knowledge pervades diverse communication spheres, producing differentiated paths of trust in science. Each path is determined by topics (environment or health-related), information sources and channels preferred, and specific features of the multifaceted notion of trust. The contribution discusses cross-national commonalities and specificities and proposes implications for science communication.

The pace and scope of digital transformation has brought about fundamental changes to science communication. These changes have so far hardly been reflected in the underlying concepts of science communication as field of research and practice. Against this backdrop, this paper asks how science communication can be conceptualized in response to fundamental societal changes brought about by digital transformation. In response to this question, this paper builds on the results of a Delphi study with 31 outstanding international science communication scholars. It presents a shared approach that conceptualizes online science communication broadly and tackles different points of view by identifying specific characteristics that enable the distinction of different settings of science communication. It is argued that such an approach should be more appropriate for a contemporary analysis of science communication and also helpful for professional communicators and policymakers to understand the interactions of science and society in the context of the digital media landscape.

This article contributes to reflective practice amongst scientists who engage with citizens in the digital public sphere, by exploring the scientists' experiences and underlying perspectives on their role repertoires in online science-society interactions. Semi-structured interviews were held with 26 European scientists to investigate their focus and contribution in boundary interactions, perspective on appropriate model of science communication, and activities, outputs and addressees in the digital public sphere — together comprising a role repertoire. The intended role of scientists often did not match with their deployed repertoire in online interactions with citizens. Participants were left with the feeling that the digital public sphere provides hollow interactions, devaluates scientific expertise or even represents a hostile environment. In order to capitalise on the promise of the digital public sphere for constructive interactions with a diverse public, a reflective practice is needed that aligns scientists' intended contribution to science-society interactions with the scientists' perspective and deployed online repertoires.
