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.

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.

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 history of public communication of science in Spain is yet to be written. Few academic studies exist that have tackled this subject. The political and economic history of the country have marked out the evolution of this discipline, which burst into the country at the end of the 20th century with the proliferation of initiatives such as the creation of science museums, the building of the Spanish Science Foundation and the development of a public Scientific Information service. Despite these efforts, the level of scientific culture for Spanish people is one of the lowest in Europe [OECD, 2016].

This contribution concerns the role of the Victorian newspaper correspondence column in advancing knowledge of dermatology in relation to corporal punishment. It explores The Times' coverage of an inquest into the death by flogging of a British soldier. I argue that on the one hand, The Times participated in the debate about flogging in the army by bringing forward skin anatomy as an argument against corporal punishment. On the other hand, the paper might have used the publication of letters with medical content as a marketing strategy to maintain its authority and credibility against accusations of sensationalism.

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.

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.

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.

Social media is restructuring the dynamics of science communication processes inside and outside the scientific world. As concerns science communication addressed to the general public, we are witnessing the advent of communication practices that are more similar to public relations than to the traditional processes of the Public Understanding of Science. By analysing the digital communication strategies implemented for the anti-vaccination documentary Vaxxed, the paper illustrates these new communication dynamics, that are both social and computational.

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.
