During the course of several decades, several scientists and groups of scientists lobbied the British Broadcasting Corporation (BBC) about science broadcasting. A consistent theme of the interventions was that science broadcasting should be given exceptional treatment both in its content, which was to have a strongly didactic element, and in its managerial arrangements within the BBC. This privileging of science would have amounted to ‘scientific exceptionalism’. The article looks at the nature of this exceptionalism and broadcasters' responses to it.

In this paper, we identify some milestones in the construction process for mobile science museums and centres in Brazil. As background for presenting the Brazilian context, we initially address the records found on the earliest travelling museum exhibitions and mobile museums in Europe and North America. We then introduce the role of UNESCO in the promotion and implementation of travelling science exhibitions and museums in several countries. Finally, we document important events in the history of mobile science museum and centres in Brazil and outline three general and inter-related challenges currently faced by them.

Modern science communication has emerged over the last 60 years as a field of study, a body of practice and a profession. This period has seen the birth of interactive science centres, the first university courses to teach the theory and practice of science communication, the first university departments conducting research into science communication, and a sharp growth in employment of science communicators by research institutions, universities, museums, science centres and industry. This chapter charts the emergence of modern science communication in Australia, against an international background.

Japan's policy of “public understanding of science” (PUS) has shifted to “science communication” since 2003. That year, there were a number of simultaneous developments with regard to science communication. The key report that advocated for the promotion of science communication and a textbook on science communication were published then. The most important consequence was that the report triggered a policy change at the Ministry of Education, Culture, Sports, Science and Technology (MEXT). The following year, MEXT published the White Paper on Science and Technology 2004, the main theme of which was concerned with science communication. Although the shift may have begun as a somewhat top-down contrivance, it has subsequently sunk down firm roots throughout Japan. In 2011 the Japanese Association for Science Communication was founded. People's awareness of science communication was significantly changed by the Great East Japan Earthquake that occurred on March 11, 2011. Why was such a policy shift possible? How did such a cascade effect occur? This paper will discuss the reasons behind these phenomena.

Between the 1950s and the 1980s the British nuclear industry engaged with ordinary people in a wide range of ways. These included articles in the print media, exhibitions and educational resources as well as through open days, developing nature reserves and building relations with the local communities around nuclear sites. This paper draws on recently collected oral history interviews and archival material to consider what was one of the largest and best resourced efforts to communicate science to the British public between the 1950s and the 1980s.

This study compares Australian government vaccination campaigns from two very different time periods, the early nineteenth century (1803–24) and the early twenty-first (2016). It explores the modes of rhetoric and frames that government officials used in each period to encourage parents to vaccinate their children. The analysis shows that modern campaigns rely primarily on scientific fact, whereas 200 years ago personal stories and emotional appeals were more common. We argue that a return to the old ways may be needed to address vaccine hesitancy around the world.

As a case study, we analyze an article of the psychiatrist Henrique Roxo published in 1942 in two publications directed to different publics. The communication of science was intended as part of Brazil's modernizing project of the epoch. Roxo's case reveals that the language used by science communicators, although sometimes of difficult apprehension, was part of an strategy of acknowledgment of the medical authority for the diagnosis and treatment of the mental illnesses.

In the last decades of the 19th century education played a major role in Mexican society, when efforts were being made to restructure it based on the objective teaching of sciences, which was regarded as the driving force behind the change needed in various sectors such as industry and public health. In this context, the so-called science disseminators aimed to communicate their knowledge to the general public, mainly to the working classes and the children. Journalism grew and reached a wide range of themes and audiences. They believed in the idea of a science for all and that sciences were an instrument to know the new nations and educate the population. It is worth mentioning La ciencia recreativa, a publication dedicated to children and working classes. Between 1871 and 1879 it was edited by the topographical engineer and surveyor José Joaquín Arriaga (1831–1896), who aimed to generalise the scientific knowledge of cosmography, mineralogy, meteorology, physics, botany, zoology, descriptive geography and industrial agriculture.

Science communication is today a well-established ―although young― area of research. However, there are only a few books and papers analyzing how science communication has developed historically. Aiming to, in some way, contribute to filling this gap, JCOM organized this special issue on the History of Public Communication of Science and Technology (PCST), joining 15 contributions, from different parts of the globe. The papers published in this issue are organized in three groups, though with diffuse boundaries: geography, media, and discipline. The first group contains works that deal descriptively and critically with the development of PCST actions and either general or specific public policies for this area in specific countries. A second set of papers examines aspects of building science communication on TV or in print media. The third group of papers presents and discusses important PCST cases in specific areas of science or technology at various historical moments.

Computational social science represents an interdisciplinary approach to the study of reality based on advanced computer tools. From economics to political science, from journalism to sociology, digital approaches and techniques for the analysis and management of large quantities of data have now been adopted in several disciplines. The papers in this JCOM commentary focus on the use of such approaches and techniques in the research on science communication. As the papers point out, the most significant advantages of a computational approach in this sector include the chance to open up a range of new research opportunities: from the study of technical and scientific controversies to citizen science, from the definition of new norms and practices for science journalism to open science issues. On the other hand, difficulties are shared with other areas of application. The main risk is that the large quantity of data available can overwhelm the importance of theory. Instead, as the papers in this commentary demonstrate, big data should push scientists to pursue a deeper epistemological and methodological reflection also in the research on science communication.
