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.

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.

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.

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].

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.

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.

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.

This article examines certain guiding tenets of science journalism in the era of big data by focusing on its engagement with citizen science. Having placed citizen science in historical context, it highlights early interventions intended to help establish the basis for an alternative epistemological ethos recognising the scientist as citizen and the citizen as scientist. Next, the article assesses further implications for science journalism by examining the challenges posed by big data in the realm of citizen science. Pertinent issues include potential risks associated with data quality, access dynamics, the difficulty investigating algorithms, and concerns about certain constraints impacting on transparency and accountability.

Online visual communication of science focuses on interactive sharing and participatory collaboration rather than simple knowledge dissemination. Visuals need to be stunning to draw people in and engage them, and a cross-media approach together with digital multimedia tools can be used to develop a clear and engaging narrative to communicate complex scientific topics. On the web both science communicators and the public manage co-create, shape, modify, decontextualise and share visuals. When it happens that low science literacy publics devoid a picture of its information assets, caption or source, they distort image meaning and perpetuate misinformation.

Although with some reluctance, social sciences now seem to have accepted the challenge deriving from the growing digitisation of communication and the consequent flow of data on the web. There are actually various empirical studies that use the digital traces left by the myriads of interactions that occur through social media and e-commerce platforms, and this trend also concerns the research in the PCST field. However, the opportunity offered by the digitisation of traditional mass media communication — the newspapers in particular — is much less exploited. Building on the experience of the TIPS project, this paper discusses the advantages and the limits of computational social science on PCST using newspapers as the main source of data. Some methodological issues are also addressed, in order to suggest a more aware use of such data and the several computational tools available for analysing them.
