This study aims to test for differences in the receptiveness of science and non-science undergraduates to positive, non-aggressive humour being used in a science article, as an exploration into the utilization of such humour as a tool for more engaging science communication. The majority of the 76 respondents to an online survey were generally receptive to such use, with some differences between the two groups. It was also noted that a receptiveness to such humour may not necessarily be associated with a receptiveness to its actual use in science articles.

A new regime of science production is emerging from the involvement of non-scientists. The present study aims to improve understanding of this phenomenon with an analysis of 16 interviews with Spanish coordinators of participatory science practices. The results indicate a majority of strategic and captive publics and point to communication as a key tool for the development of successful practices. Five key elements of the degree of integration required to develop a citizen participation in science practice were analysed: derived outputs, level of participant contribution, participation assessment, practice replicability, and participant and facilitator training. Proposals for strategies to remove barriers to citizen participation are the study's principal contribution.

Since the COVID-19 pandemic hit the global community, politicians as well as scientists increasingly turn to Twitter to share urgent health information using various message styles. The results of our 2x2 between-subject experiment show that if a Tweet is written in lower-case letters, participants perceive the information source as more trustworthy. Furthermore, the information is perceived as more credible, and people are more willing to read the health information and share it via social media. Furthermore, scientists are perceived as possessing more expertise than politicians. However, politicians are perceived as possessing more integrity and benevolence than scientists.

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.

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.

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.

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 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.
