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.

Of all the online information tools that the public relies on to collect information and share opinions about scientific and environmental issues, Twitter presents a unique venue to assess the spontaneous and genuine opinions of networked publics, including those about a focusing event like the Fukushima Daiichi nuclear accident following the 2011 Tohoku earthquake and tsunami. Using computational linguistic algorithms, this study analyzes a census of English-language tweets about nuclear power before, during, and after the Fukushima nuclear accident. Results show that although discourse about the event may have faded rapidly from the news cycle on traditional media, it evoked concerns about reactor safety and the environmental implications of nuclear power, particularly among users in U.S. states that are geographically closer to the accident site. Also, while the sentiment of the tweets was primarily pessimistic about nuclear power weeks after the accident, overall sentiment became increasingly neutral and uncertain over time. This study reveals there is a group of concerned citizens and stakeholders who are using online tools like Twitter to communicate about global and local environmental and health risks related to nuclear power. The implications for risk communication and public engagement strategies are discussed.

Volunteer water quality monitors represent the intersection between citizen science and environmental stewardship. Understanding what motivates participation will enable project managers to improve recruitment and retention. This survey of 271 volunteers from eight water quality monitoring organizations in the U.S. found the strongest motivators to participate are helping the environment or community and contributing to scientific knowledge. No variation by gender was found, but younger volunteers have different motivations and preferences than older volunteers. Volunteers value the communication of tangible results more than recognition or reward.

The prevalent lack of research on the interrelations between science, research and popular culture led to the organization of the first International Conference on Science and Research in Popular Culture #POPSCI2015, which took place at Alpen-Adria-Universität in Klagenfurt, Austria, from 17--18 September 2015. The aim of the conference was to bring together not only science communication researchers with an interest in popular culture, but also other scholars, scientists and researchers, artists, media professionals and members from the general public. In this issue of JCOM we present four invited commentaries which are all based on presentations at the conference.

Interviews were conducted with 110 marine users to elicit their salient beliefs about recording marine species in a citizen science project. The results showed that many interviewees believe participation would increase knowledge (either scientific, the community's, or their own). While almost half of the interviewees saw no negative outcomes, a small number expressed concerns about targeting of marine species by others, or restrictions on public access to marine sites. Most of the people surveyed (n = 106) emphasised the importance of well-designed technological interfaces to assist their data collection, without which they would be unlikely to engage in the project.

A survey was conducted during the University of Manchester’s 2014 ‘Science Extravaganza’, which saw the participation of over 900 Key Stage 3 (ages 11–14) students in a range of interactive demonstrations, all run by active University researchers. The findings of this study suggest that a new approach is necessary in order to use these large science events to actively engage with school students about the career opportunities afforded by science subjects. Recommendations for such an approach are suggested, including the better briefing of researchers, and the invitation of scientists from outside academia to attend and interact with the school students.
