Science festivals (or just “festivals”) are currently ascendant in the United States with more than 40 new initiatives emerging in just the past 5 years, but their story is not so easily told. The schedule of any one individual festival may contain a staggering array of events, and each festival is different both from year to year, and from other festivals. One multi-festival evaluation points to potential strengths of the format, as well as the importance of the participation of STEM practitioners. Collaboration and social identity formation are considered as powerful festival impacts, and potential challenges for festivals are discussed.

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.

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.

This essay intends to present and reflect on the production and reception of sound language styles in a radio programme discussing science called Universidade das Criancas UFMG (UFMG Children’s University). This programme, aimed at children, is broadcast on the UFMG (Federal University of Minas Gerais) Educational Radio Station, located in Belo Horizonte, Minas Gerais, Brazil.

Thailand’s National Science Fair is an annual two-week event held to promote science, encourage learning and prove that science is for everyone. Derived from the first ‘Thai National Science Day’ in 1982, the fair now hosts over 1 million visitors, with exhibits from over 50 national and international companies and institutions from governmental, educational and commercial sectors. Whilst the fair is normally held in Bangkok the outreach program holds mini fairs for 32 Universities and numerous schools across the nation for local participation in science week. This paper discusses the past, present and future of the fair, incorporating existing evaluation findings and identified key challenges.

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.

We analysed the representations of science and of scientists at Jornal Nacional, the main Brazilian TV news. We carried out content and frames analysis, besides the lexical and semantic analysis of the transcriptions of the science and technology stories. Our results show a narrative that highlights the novelties and the epopee of the scientific advance, mainly in the health field. But to the emotional palette feelings of combat, anxiety and triumph were added. The face of the scientist presented by the TV news is mainly masculine, suggesting a stereotyped role of the male and female scientist: meanwhile men go out to literally explore other worlds, women take care of health and of the body.

The purpose of this study is to quantify the use of science fiction films in academic papers as well as to analyse the patterns of use of those films indexed in international databases, using the ISI Web of Science database. Twenty films were selected from recognised sources. Films referenced in the scientific literature were detected and, with quantitative methodologies, we classified their genres, the journals of publication and the disciplines they belong to. Finally, we performed a detailed study of each paper in which selected films were found, to observe and categorise specifically the ways such film references are used.

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.
