By focusing on a specific episode of 20th Century physics — the discovery of parity violation in 1957 — the paper presents a study of the types of explanations of the crucial experiment as they are found in different editorial categories: a peer-review journal, a popular science book, an encyclopedia and a newspaper articles. The study provides a fine-grained description of the mechanism of the explanation as elaborated in non-specialist accounts of the experiment and identifies original, key-explanatory elements which characterize them. In so doing, the paper presents a reflection on the processes of transformation and adaptation implied by the circulation of knowledge — which features as a productive process in its own right — and shows which further insights a focus on explanation can offer to the current historical researches on science communication.

This paper explores the combined effects of everyday life technological devices and advertisements in constituting an efficient way to scientific popularization. We, therefore, analyze mobile telephony advertisements published in a high-circulation Spanish newspaper — La Vanguardia — between 1994 and 1999. We identify content that promoted knowledge about the devices, the service, or the uses of this groundbreaking technology. Advertisements also attach attributes to technology — modernity, freedom, or efficiency. We suggest that the analysis of advertisements that promote everyday life digital devices allows a better understanding of what (digital) technology means to publics.

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.

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.

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.

Previous studies have concluded that science coverage in Soviet countries was determined by the ideological function of the media. This paper analyses the science coverage in Soviet Estonian publications Rahva Hääl and Horisont in 1960/1967 and 1980 and demonstrates that the popularization of science existed as an independent function of articles. This suggests that the parallel developments in science communication on both sides of the Iron Curtain deserve further study.

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.

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.
