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.

Science communication continues to grow, develop and change, as a practice and field of research. The boundaries between science and the rest of society are blurring. Digitalization transforms the public sphere. This JCOM special issue aims to rethink science communication in light of the changing science communication landscape. How to characterize the emerging science communication ecosystem in relation to the introduction of new media and actors involved? What new practices are emerging? How is the quality of science communication maintained or improved? We present a selection of papers that provide different perspectives on these questions and challenges.

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”.

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.

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'.

The promotion of quality is a critical aspect to consider in the re-examination of science communication. This problem is analysed in the research carried out by the QUEST project, as featured in this paper. Engaging key stakeholders in a codesign process — through interviews, focus groups, workshops and surveys — the research identified barriers to quality science communication and on the basis of these, proposes a series of tools and supporting material that can serve as incentives toward quality science communication for different stakeholders across the fields of journalism, social media, and museum communication. And it highlights in particular the significance of training in order to promote professionalism amongst communicators.

This study explores the types of actors visible in the digital science communication landscape in the Netherlands, Serbia and the U.K. Using the Koru model of science communication as a basis, we consider how science communicators craft their messages and which channels they are using to reach audiences. The study took as case studies the topics of climate change and healthy diets to enable comparison across countries, topics and platforms. These findings are compared with the results from a survey of over 200 science communication practitioners based in these countries. We find that although traditional media are challenged by the variety of different new entrants into the digital landscape, our results suggest that the media and journalists remain highly visible. In addition, our survey results suggest that many science communicators may struggle to gain traction in the crowded digital ecology, and in particular, that relatively few scientists and research institutions and universities are achieving a high profile in the public digital media ecology of science communication.

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 paper explains how a participative approach was used to collect first-hand citizens’ suggestions on how to improve science communication regarding Climate Change. A public consultation involving citizens from 5 different European countries revealed various perspectives concerning their communication preferences on scientific topics. Five main themes emerged following citizens' proposals for better communication and involvement: producer of information, medium, message strategies, audiences and areas of action and engagement.
