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.

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.

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.

For the past thirty years, The National Institute of Higher Education, Research, Science and Technology (NIHERST), Trinidad and Tobago, has been a pioneering force in science popularization both locally and regionally. The biennial NIHERST Sci-TechKnoFest is the Caribbean’s premier science festival, having hosted seven large-scale events catering to tens of thousands of patrons each. This article provides an overview of the role of NIHERST at the national development level, an in-depth look at the content of Sci-TechKnoFest 2013, its impacts on visitors and the way forward for the festival.

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.

Public communication from research institutions often functions as both science communication and public relations. And while these are distinct functions, public relations efforts often serve as science communication tools. This is because successful science communication and public relations efforts for research institutions both rely on finding shared language and disseminating findings in context.

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 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.

Public participation in decision-making has in the last decades become a common refrain in political and scientific discourse, yet it does not often truly come to fruition. The present study focuses on the underlying issue, that of the construction of the difference between scientific and public knowledge and its consequences. Through discourse analysis of scientific texts on sustainable development three distinct groups of Slovenian social scientists were discerned that differed in their views on the relationship between scientific and public knowledge and consequently the role and nature of public participation in decision-making processes. With a rise in participatory practices the preponderance of the deficit model found in this study remains problematic.
