Public engagement with science activities need to be extended beyond traditional learning venues (e.g., museums, schools) to increase public access. Scientists are motivated to carry out this work; however, it is difficult to scale up training to support the implementation of engagement activities in non-traditional venues. Such training would need to be applicable to different engagement contexts, while avoiding a “one size fits all” approach. We describe the guiding principles, challenges, and design choices of a training program in the United States to support scientists in designing and implementing audience-specific engagement activities in a range of non-traditional venues.

BioBlitzes, typically one-day citizen science (CS) events, provide opportunities for the public to participate in data collection for research and conservation, potentially promoting deeper engagement with science. We observed 81 youth at 15 BioBlitzes in the U.S. and U.K., identifying five steps participants use to create a biological record (Exploring, Observing, Identifying, Documenting and Recording). We found 67 youth engaged in at least one of the steps, but seldom in all, with rare participation in Recording which is crucial for contributing data to CS. These findings suggest BioBlitzes should reduce barriers to Recording for youth to increase engagement with science.

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.

In the changing science communication landscape, researchers may govern their public science-society relations through the social media connections at their fingertips. However, digital media outreach may create challenges for researchers and cause changes in the communication professionals' role. The aim of this qualitative interview study was to enhance understanding of the challenges in the rarely explored organizational collaboration between researchers and communication professionals. The results identify ambiguous duties and responsibilities, as well as blurring boundaries of occupational roles and coordination challenges in content production.

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.

In this essay the authors reflect on some recent trends in science communication research, celebrating it as an inherently interdisciplinary endeavour. Some current tendencies in science communication are more limiting, however: they present theoretical and strategic prescriptions that do not adquately reflect the variety and cultural diversity of science communication internationally. Rethinking science communication in the context of such diverse practices and cultural reorientations, the authors revise some of their own views and revisit notions of communication as conversation to propose an inclusive definition of science communication as the social conversation around science.

Citizen science is a transdisciplinary approach that responds to the current science policy agenda: in terms of supporting open science, and by using a range of science communication instruments. In particular, it opens up scientific research processes by involving citizens at different phases; this also creates a range of opportunities for science communication to happen This article explores methodological and practical characteristics of citizen science as a form of science communication by examining three case studies that took different approaches to citizens' participation in science. Through these, it becomes clear that communication in citizen science is ‘÷always’ science communication and an essential part of “doing science”.

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.
