In this book, Brian G. Southwell discusses how disparities in information-sharing arise and what can be done to alleviate them. In all sorts of ways and for all sorts of reasons, people have always sought to share information among their family and other social networks. However, this sharing has never been equal: inevitably, some people are better-informed than others and some are more socially-connected than others. At first glance, the plethora of communication tools and technologies available nowadays should help democratise information and reduce disparity but differences in how, when and with whom information is shared create conversation gaps and maintain inequalities. Southwell explores and catalogues information-sharing behaviours, discusses the factors that affect how and why we share information and addresses the questions of why disparities in information-sharing matter and what we can do about the gaps between ‘information-haves’ and ‘information have-nots’.

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.

There is growing competition among publicly funded scientific institutes and universities to attract staff, students, funding and research partners. As a result, there has been increased emphasis on science communication activities in research institutes over the past decade. But are institutes communicating science simply for the sake of improving the institute’s image? In this set of commentaries we explore the relationship between science communication and public relations (PR) activities, in an attempt to clarify what research institutes are actually doing. The overall opinion of the authors is that science communication activities are almost always a form of PR. The press release is still the most popular science communication and PR tool. There is however disagreement over the usefulness of the press release and whether or not gaining public attention is actually good for science.

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.

Antibiotic resistance is an increasing global threat involving many actors, including the general public. We present findings from a content analysis of the coverage of antibiotic resistance in the Swedish print media with respect to the risk communication factors cause, magnitude and countermeasures. The most commonly reported cause of development and spread of resistance was unnecessary prescription of antibiotics. Risk magnitudes were mostly reported qualitatively rather than using quantitative figures. Risk-reduction measures were analyzed using a framework that distinguishes between personal and societal efficacy. Measures at the societal level were more commonly reported compared to the individual level.

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 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.

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.
