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.

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.

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.

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.

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.

Science communication as an interdisciplinary field of study has always been concerned with issues of knowledge utilisation. This theoretical paper focusses on the “knowledge” part of knowledge utilisation and provides a conceptual frame to distinguish between different types of knowledge in science-based practice. A practitioner’s knowledge store is portrayed as a dense set of personal knowledge, consisting of procedural knowledge, factual knowledge, potential factual knowledge and opinions/beliefs; the totality of which is continuously refined through more experiences and additional information received from people, documents or events. Implications for future studies of knowledge utilisation in science-based practices are highlighted and a number of questions posed to science communication as a profession.
