New public participatory modes of practice are emerging in fields as diverse as politics, healthcare and research. In part, these DIY and citizen-led initiatives have gained momentum from the optimism of new technologies, which allow unprecedented access to previously inaccessible knowledge and tools. Equally, they are the result of a growing frustration with power hierarchies and systems that reinforce elites. Experts are increasingly regarded with suspicion as trust in public institutions is eroded and individuals begin to give more weight to personal accounts, and information shared within networks of peers. In this climate there is a critical need for improved knowledge transfer practices based on improved empathy, understanding and communication of shared values and motivations. In this session we questioned the role of expertise in a changing landscape of knowledge production and practice. Using the lens of science & technology communication and hands-on DIY practices, we explored how to move towards a more inclusive model of knowledge transfer, where different types of expertise are acknowledged and valued.

The Science in Public Conference, held this year at the University of Sheffield, generated animated discussion of a wide range of topics. Six commentaries cover conference themes around engagement with science and technology and how science and technology are shaping what it means to be human. The commentaries range from discussions of our relationship with expertise and how science communication can better act as a knowledge broker in a time of ‘alternative facts’ to exploration of fictional narratives and how they might be used to open up dialogue about science and technology.

To unravel how science museums can prepare citizens for reflection on research and innovation, this study evaluates a playful exhibit prototype, Opinion Lab (OL). The OL made children and parents reflect on synthetic biology (SB), supported by conversation exercises, citizen-narratives, and futuristic scenarios. We analysed 26 OL test sessions performed in NEMO science museum Amsterdam. The prototype appeared to support participants in opinion forming, counter-argument incorporation and extrapolation. Also, reflection on deeper questions such as `what is nature?' evoked understanding for alternative viewpoints. These findings show that playful exhibits, like the OL, potentially facilitate dialogue in science museums very well.

Although with some reluctance, social sciences now seem to have accepted the challenge deriving from the growing digitisation of communication and the consequent flow of data on the web. There are actually various empirical studies that use the digital traces left by the myriads of interactions that occur through social media and e-commerce platforms, and this trend also concerns the research in the PCST field. However, the opportunity offered by the digitisation of traditional mass media communication — the newspapers in particular — is much less exploited. Building on the experience of the TIPS project, this paper discusses the advantages and the limits of computational social science on PCST using newspapers as the main source of data. Some methodological issues are also addressed, in order to suggest a more aware use of such data and the several computational tools available for analysing them.

How users discuss climate change online is one of the crucial questions (science) communication scholars address nowadays. This study contributes by approaching the issue through the theoretical concept of online public arenas. The diversity of topics and perceptions in the climate change discourse is explored by comparing different arenas. German journalistic articles and their reader comments as well as scientific expert blogs are analyzed by quantitative manual and automated content analysis (n=5,301). Findings demonstrate a larger diversity of topics and interpretations in arenas with low barriers to communication. Overall, climate change skepticism is rare, but mostly present in lay publics.

In an information free-for-all why should scientists bother to add their voice? In this commentary piece I argue there is an increasingly important role for scientists amongst the growing ranks of public intellectuals and the many who style themselves as such. First, we must become the sifters and sorters. We need to be willing to use our research and analytical skills to identify what is valuable amongst all the noise, and, if necessary, to volubly reject what is not. And, second, we need to create and defend the space everyone needs for deep thought and consideration. We need to influence ongoing debates by seeking to push them towards evidence-based arguments and areas of scientific consensus. To sift out the deliberately distracting stories and to counter fake news.

This article proposes a classification of the current differences between online videos produced specifically for television and online videos produced for the Internet, based on online audiovisual production on climate change. The classification, which consists of 18 formats divided into two groups that allow comparisons to be made between television and web formats, was created through the quantitative and qualitative content analysis of a sample of 300 videos. The findings show that online video's capacity to generate visits is greater when it has been designed to be broadcast on the Internet than when produced for television.

Englehard et al. provide a wide-ranging look at synthetic biology, from discussion of how one might classify different synthetic approaches to consideration of risk and ethical issues. The chapter on public engagement considers why synthetic biology seems to sit below the public radar.

This letter reflects on how the role of science in society evolved in 2016. While there were plenty of groundbreaking scientific discoveries, the shifting political landscape cultivated a tempestuous relationship between science and society. We discuss these developments and the potential role of the science communication community in political activism.

Social media is increasingly being used by science communicators, journalists and government agencies to engage in discourse with a range of publics. Despite a growing body of literature on Twitter use, the communication of science via Twitter is comparatively under explored. This paper examines the prominence of scientific issues in political debate occurring on Twitter during the 2013 and 2016 Australian federal election campaigns. Hashtracking of the umbrella political hashtag auspol was used to capture tweets during the two campaign periods. The 2013 campaign was particularly relevant as a major issue for both parties was climate change mitigation, a controversial and partisan issue. Therefore, climate change discussion on Twitter during the 2013 election was used as a focal case study in this research. Subsamples of the 2013 data were used to identify public sentiment and major contributors to the online conversation, specifically seeking to see if scientific, governmental, media or ‘public' sources were the more dominant instigators. We compare the prominence of issues on Twitter to mainstream media polls over the two campaign periods and argue that the potential of Twitter as an effective public engagement tool for science, and for politicised scientific issues in particular, is not being realised.
