The National Autonomous University of Mexico (UNAM) is one of the world's single largest employers of science communicators, with over 350,000 students and 40,000 staff. Its science communication activities include five museums (Universum, Museo de la Luz, the Geology Museum, Museo de la Medicina Mexicana and Musem of Geophysics), botanical gardens, as well as a wide range of cultural and outreach activities. It has several programmes for training professional science communicators. The science communication staff are spread across the campuses in Mexico City and four other cities, including writers, explainers, researchers, evaluators, who produce exhibitions, magazines, books, theatre, screenings and science cafés. This activity is diverse and sometimes operates to different agendas.

Marked by the diversity of initiatives linking science and art and by new presentation formats, the 15th Congress of the Network for Popularisation of Science and Technology in Latin America and the Caribbean (RedPOP) saw heated debates on science, culture, politics and society. Between 21st and 25th August, it brought together in Buenos Aires (Argentina) about 400 participants from 14 countries in order to share new visions, initiatives and research work in science communication. During the event, which included a vast cultural programme, a series of challenges were raised for the future development of the field.

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.

The research field of science communication is fairly neglected in South Africa. The university system in South Africa, with a few exceptions, pays scant attention to the teaching of science communication, leading to limited academic knowledge of this research field with its rich history and philosophical relations. This paper explores some of the reasons behind this neglect of science communication in South Africa and will argue and demonstrate that, primarily, two political systems can be identified as having had a profound impact on the lesser attention given to this research field; the ‘divide and rule’ system of British colonialism and the Afrikaner National Party ‘apartheid’ system of racial segregation.

Research in the field of science communication started emerging about 50 years ago and has since then matured as a field of academic enquiry. Early findings about research-active authors and countries reveal that scholarly activity in the field has traditionally been dominated by male authors from English-speaking countries in the West. The current study is a systematic, bibliographic analysis of a full sample of research papers that were published in the three most prominent journals in the field from 1979 to 2016. The findings reveal that early inequities remain prevalent, but also that there are indications that recent increases in research outputs and trends in authorship patterns ― for example the growth in female authorship ― are beginning to correct some of these imbalances. Furthermore, the current study verifies earlier indications that science communication research is becoming increasingly institutionalised and internationalised, as demonstrated by an upward trend in papers reflecting cross-institutional collaboration and the diversity of countries where authors are based.

The academic interest in 'science and technology communication' has evolved from different societal domains and fields of application, giving rise to different scholarly traditions. This contribution introduces current issues and agendas in a field that has its origin at the interface of (agricultural) innovation studies, rural development sociology and the communication sciences. The paper starts with a brief sketch of the history of the field. When compared to earlier approaches, current thinking about 'communication, innovation and development' pays greater attention to limitations in the potential of orchestrating change and innovation in pre-planned directions, and to political and institutional dimensions of both communication and innovation. In relation to this, new lines of questioning are discussed. The article ends with a reflection on the usefulness of the thinking from different historical periods today. It is argued that approaches to science and technology communication need to be matched with the level of complexity of the issue at hand.

This issue sees the publication of several papers that contribute to our understanding of the challenges faced by researchers in communicating about their research, adding richness to our understanding of practices and policies in Zimbabwe as well as amongst non-Anglophone speakers working in Australia. The potential of incorporating documentary filmmaking tools and techniques into open science projects raises interesting questions about subjectivity, data and the collaboration skills needed for today's scientists.

This study of the science communication views and practices of African researchers ― academics at the National University of Science and Technology (NUST) in Zimbabwe ― reveals a bleak picture of the low status of public science engagement in the developing world. Researchers prioritise peer communication and pay little attention to the public, policy makers and popular media. Most scientists believe the public is largely not scientifically literate or interested in research. An unstable funding environment, a lack of communication incentives and censoring of politically sensitive findings further constrain researchers' interest in public engagement. Most NUST academics, however, are interested in science communication training. We suggest interventions that could revive and support public science engagement at African universities.

This paper contains an overview of the programmes currently existing in Latin America to train science communicators. For such purpose, only postgraduate courses held regularly were considered in the study. Twenty-two programmes meeting such requirement were identified in five countries, 65% of which were in fact established over the past ten years. They present a lot of diversity in terms of admittance requirements, goals, contents, approaches, duration and graduation requirements. However, all of them share the same effort, aiming to offer specific contents in the area of science communication.

Throughout the second half of the twentieth century a varied collection of pressure mechanisms were deployed from nuclear technology exporting countries — mainly from the US — to obstruct the development of a group of semi-peripheral countries’ autonomous nuclear capabilities. Argentina was part of this group. This article focuses on how “fear” of nuclear proliferation was used by US foreign policy as one of the most effective political artifacts to construct and protect an oligopolistic nuclear market.
Spread by the press and by some prestigious social science sectors from the US and some European countries, a persistent and dense discourse production was devoted over several decades to the bizarre practice of “calculating” the alleged hidden intentions of those semi-peripheral countries which aspired to dominate as many technologies of the nuclear
fuel cycle as possible.
