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.

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.

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.

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.

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.

The future challenges within science communication lie in a 'grey area' where the frontiers between production and sharing of knowledge are blurred. An area in which we can satisfy at the same time and within the same activity the autonomous interests of researchers and those of other stakeholders, including lay publics. Settings are emerging, where we can provide real contribution to scientific research and at the same time facilitate the publics in their process of hacking scientific knowledge to serve autonomously defined and often unpredictable functions. Some are linked to research institutes, others to science centres, others are precisely inbetween. This editorial explores why these special places are needed, and present some case studies, leading to the need of interpreting science culture centres as research facilities.

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.

Science in film is gaining attention from scientists and science communicators. Sixteen experts gathered at the 253rd Annual Meeting of the American Chemical Society to explore the role and relevance of science in film. An audience of researchers, academics and students enjoyed first-hand accounts from filmmakers, science consultants and experts in science communication, who all agreed on the important impact the way science is depicted in film has on education, outreach and the relationship between science and society.

How users discuss climate change online is one of the crucial questions (science) communication scholars address nowadays. This study contributes by approaching the issue through the theoretical concept of online public arenas. The diversity of topics and perceptions in the climate change discourse is explored by comparing different arenas. German journalistic articles and their reader comments as well as scientific expert blogs are analyzed by quantitative manual and automated content analysis (n=5,301). Findings demonstrate a larger diversity of topics and interpretations in arenas with low barriers to communication. Overall, climate change skepticism is rare, but mostly present in lay publics.
