The cultural phenomenon of ‘science festivals’ is ever expanding throughout the world, as universities, city and regional governments, and science engagement professionals alike embrace the concept of a focused ‘celebration’ of science. In the past however science festivals have been criticized for neglecting underrepresented audiences. This special issue explores the extent to which current science festivals have managed to engage with diverse publics, and identifies the key challenges facing the future of science festivals, most notably the need for deeper research into the impacts of science festivals.

Over the past decades there has been an increasing recognition of the need to promote dialogue between science and society. Often this takes the form of formal processes, such as citizen’s juries, that are designed to allow the public to contribute their views on particular scientific research areas. But there are also many less formal mechanisms that promote a dialogue between science and society. This editorial considers science festivals and citizen science in this context and argues that we need a greater understanding of the potential impacts of these projects on the individuals involved, both scientists and the public.

Scientists often cite discrepancy between scientific values and news values as a primary factor in poor quality science reporting. The goal of this study was to understand how news values including conflict and controversy affect science communicators’ evaluation of press releases containing quotes from outside expert sources. Results of an online survey experiment suggest science communicators find a climate science press release with an outside expert quote that introduces controversy to be more newsworthy. However, when a science communicator attributes relatively high importance to reliability of facts as a guiding principle in story selection, this preference for controversy is reversed.

The Internet is increasingly considered as a legitimate source of information on scientific and technological topics. Lay individuals are increasingly using Internet sources to find information about new technological developments, but scientific communities might have a limited understanding of the nature of this content. In this paper we examine the nature of the content of information about fusion energy on the Internet. By means of a content and thematic analysis of a sample of English-, Spanish- and Portuguese-language web documents, we analyze the structural characteristics of the webs, characterize the presentation of nuclear fusion, and study the associations to nuclear fission and the main benefits and risks associated to fusion technologies in the Web. Our findings indicate that the information about fusion on the Internet is produced by a variety of actors (including private users via blogs), that almost half of the sample provided relevant technical information about nuclear fusion, that the majority of the web documents provided a positive portrayal of fusion energy (as a clean, safe and powerful energy technology), and that nuclear fusion was generally presented as a potential solution to world energy problems, as a key scientific challenge and as a superior alternative to nuclear fission. We discuss the results in terms of the role of Internet in science communication.

This issue of the Journal of Science Communication raises a number of questions about the ways that new scientific research emerges from research institutions and in particular the role played by scientists, press officers and journalists in this process. This is not to suggest that the public don't play an equally important role, and several articles in this issue raise questions about public engagement, but to explore the dynamics at play in one specific arena: that of news production. In this editorial I explore the increasing reliance of science journalists on public relations sources and consider what questions this raises for science communication.

The PCST conference attracts a substantial number of science communication academics and practitioners from all over the world. The conference is stimulating and refreshing but the size of it means that quality control is challenging for the organisers. This review highlights areas of both strengths and weaknesses whilst also making recommendations to the PCST committee for PCST 2016. The committee are encouraged to further strengthen the academic/practitioner combination and the international nature of the event. However, they are also recommended to ensure that work presented is of high quality with clear purposes and strong evaluative evidence presented.

The urgent state of our global environment calls for collective action, which depends in large part on effective science communication for better understanding and awareness. Activities and institutions that provide opportunities to learn about nature all ultimately rely on scientific findings about nature. Although science produces the knowledge and information about nature, for the content to be accessible and meaningful to the general public, it needs to be processed by what I call science content design. This process is similar to the concepts of interpretation in tourism, or aesthetic understanding in alternative science education. This study is a theoretical exploration on the definition and nature of science content design, what constitutes its process, and how the content can be designed. Focusing on the fields of macro-biology, I also discuss the types of biological content generally used in nature-based experiences, and examine model cases of biological content design.

The 13th International Public Communication of Science and Technology Conference (PCST) conference offered a valuable opportunity for over 500 science communicators to congregate and network with the international community. While the sheer size of the event made fostering debate somewhat of a challenge, the pertinent theme of ‘science communication for social inclusion and political engagement’, inspired some thought-provoking talks. Certainly, it was an appropriate time for this topic to be explored in Brazil, a developing country with a national government actively working towards greater social inclusion and local scientific development.

Attendance at any large conference is highly personal and every registrant has a unique experience. The value to the individual depends on which sessions they attend, whom they connect with and what outcomes eventuate from what they learn and the networking they do. The networking and feedback can be life changing as it was for me when I attended PCST in 1996 in Melbourne. PCST2014 was a successful conference that provided many options for delegates. This was my fifth PCST and I was glad to have made the long trip to Brazil. One of the most successful aspects of PCST2014 was the opportunity to hear voices that I had not heard at previous PCSTs. The opportunity to hear about interesting work and different perspectives is one of the main advantages of this large, diverse, international network. Some reflective presentations eloquently articulated the familiar but evolving framework of the science communication discipline. Some provocative presentations pushed me to consider new and different perspectives or methodologies. Some case study presentations illustrated that good science communication is happening around the world. All types are particularly useful to those of us at a crossroad in our career, considering where to invest our energy, expertise and time.
