Science cafés offer a place for information and discussion for all who are interested in science and its broader implications for society. In this paper, science cafés are explored as a means of informal science dialogue in order to gain more understanding of the science-society relationship. Perspectives of visitors, organisers and moderators of science cafés were analysed. Findings show that science cafés stimulate discussion and engagement via informal learning processes. Visitors come to broaden their knowledge in an informal ambiance. Organisers and moderators hope to enhance understanding of science and confidence of people to participate in debates.

Citizen science continues to grow, potentially increasing competition among projects to recruit and retain volunteers interested in participating. Using web analytics, we examined the ability of a marketing campaign to broaden project awareness, while driving engagement and retention in an online, crowdsourced project. The campaign challenged audiences to support the classification of >9,000 pairs of images. The campaign was successful due to increased engagement, but it did not increase the time participants spent classifying images. Engagement over multiple days was significantly shorter during the campaign. We provide lessons learned to improve targeted recruitment and retention of participants in online projects.

This paper provides an analysis of the implementation and the outcomes of Scienza Attiva, an Italian national project for secondary school students, that makes use of deliberative democracy tools to address socio-scientific issues of great impact. The analysis has required a mixed method including surveys of students' pre- and post-project opinions, focus groups and interviews with students and teachers. The results from this evaluation study provide evidence that the project improves students' understanding of socio-scientific issues, strengthens their awareness of the importance of discussion and positively influences interactions in the classroom.

This issue sees the publication of several papers that contribute to our understanding of the challenges faced by researchers in communicating about their research, adding richness to our understanding of practices and policies in Zimbabwe as well as amongst non-Anglophone speakers working in Australia. The potential of incorporating documentary filmmaking tools and techniques into open science projects raises interesting questions about subjectivity, data and the collaboration skills needed for today's scientists.

Much of science communication is peer-to-peer communication in collaborative networks for innovation from the fuzzy front-end of innovation until the marketing back-end. Scientists and engineers at meetings tables talking about new developments. Or scientists and engineers in collaboration with industry and policy makers, discussing various scenarios for implementation of e.g. health care services. However, this focus on science communication 'within the action' of uncertain development of science and technology and its attached academic domains such as innovation studies, high-tech marketing and branding, is not often discussed in the science communication literature. Lacking these considerations at this micro-level communication, means we have an incomplete picture of the ways that discourses develop and are shaped by actors, particularly during the upstream phases of innovation.

Differences in viewpoints between science and society, like in for example the HPV-vaccination debate, should be considered from a socio-technical system perspective, and not solely from a boundary perspective between the lay public, medical doctors and scientists. Recent developments in the HPV-vaccination case show how the debate concerning uncertainty amongst scientists and the lay audience is mostly focussed on the improvement of understanding of lay people about why vaccination is important. This boundary thinking leads to the idea that once the boundary is crossed, the problem is solved. However, such ‘bug-fixing’ and technocentric boundary thinking is not leading to sustainable resolutions. We view science communication as a key aspect of the socio-technical system of scientific, technological and innovation  development, in which the vaccine and its corresponding immunisation program are socially constructed. A process of construction that takes place all the way from the fuzzy front-end of their scientific conception until the marketing back-end. The authority, legitimacy and therefore the license to operate of scientists, engineers and policy makers are discussed, primarily at this boundary, but develops during the whole process of innovation. During upstream processes, professional roles and according behaviour are also defined.

In this commentary we state that the development of science communication strategies should also start upstream, and that the ‘bug-fixes’ of improved listening to (and not by) the lay audience, could be become a more sustainable solution to the HPV-debate if this process of listening by experts considers the socio-technical system of vaccination as a whole. One of the outcomes might be that the dialogue between scientists, policy makers and the lay audience is about the various possible scenarios that deal with inherent scientific and societal uncertainty in which the inevitable uncertainty of science becomes more explicit. It is not known according whether this will lead to more profound interactions, however we would like to explore this possibility a bit more from an uncertain innovation process point of view. This could clear the way for a process of co-inquiry into ideas concerning shared responsibility and accountability. The latter means that the focus in the debate is more balanced and concerns the social network, and is not purely focussed on the betterment ofunderstanding by the lay  audience. Moreover, in this way we consider communication and interaction between actors not as a means of crossing any boundaries (since that may be impossible), but as a means to perturb a status quo or equilibrium within a network of actors. This makes apparent boundaries more explicit and discussable. Methods of interaction, e.g. based on concepts like midstream modulation, may lead to another discourse and give way to new dynamics in this social system.

In today's society a variety of challenges need attention because they are considered to affect our well-being. Many of these challenges can be addressed with new innovations, yet they may also introduce new challenges. Communication of these new innovations is vital. This importance is also addressed by the concept of Responsible Research and Innovation. In the present commentary we draw on a dataset of 196 research projects and discuss the two research streams of Science Communication and Responsible Research and Innovation and how they are complements to each other. We conclude with suggestions for practitioners and scientists.

This paper argues that for citizens to be engaged with science they need to be able to share analytical techniques as well as the results of analyses. The category of "brand" which condenses the instrumental with the symbolic is both powerful in its uses and familiar to laypeople. The paper shows briefly how the categories of penicillin, biotechnology and applied science can be analysed in this way. It suggests that historians apply such an approach to the historiography of such new categories as synthetic biology and that this might be useful to curators of such topics in museums.

The academic interest in 'science and technology communication' has evolved from different societal domains and fields of application, giving rise to different scholarly traditions. This contribution introduces current issues and agendas in a field that has its origin at the interface of (agricultural) innovation studies, rural development sociology and the communication sciences. The paper starts with a brief sketch of the history of the field. When compared to earlier approaches, current thinking about 'communication, innovation and development' pays greater attention to limitations in the potential of orchestrating change and innovation in pre-planned directions, and to political and institutional dimensions of both communication and innovation. In relation to this, new lines of questioning are discussed. The article ends with a reflection on the usefulness of the thinking from different historical periods today. It is argued that approaches to science and technology communication need to be matched with the level of complexity of the issue at hand.

We present an exploratory study of science communication via online video through various UK-based YouTube science content providers. We interviewed five people responsible for eight of the most viewed and subscribed professionally generated content channels. The study reveals that the immense potential of online video as a science communication tool is widely acknowledged, especially regarding the possibility of establishing a dialogue with the audience and of experimenting with different formats. It also shows that some online video channels fully exploit this potential whilst others focus on providing a supplementary platform for other kinds of science communication, such as print or TV.
