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.

Social media is increasingly being used by science communicators, journalists and government agencies to engage in discourse with a range of publics. Despite a growing body of literature on Twitter use, the communication of science via Twitter is comparatively under explored. This paper examines the prominence of scientific issues in political debate occurring on Twitter during the 2013 and 2016 Australian federal election campaigns. Hashtracking of the umbrella political hashtag auspol was used to capture tweets during the two campaign periods. The 2013 campaign was particularly relevant as a major issue for both parties was climate change mitigation, a controversial and partisan issue. Therefore, climate change discussion on Twitter during the 2013 election was used as a focal case study in this research. Subsamples of the 2013 data were used to identify public sentiment and major contributors to the online conversation, specifically seeking to see if scientific, governmental, media or ‘public' sources were the more dominant instigators. We compare the prominence of issues on Twitter to mainstream media polls over the two campaign periods and argue that the potential of Twitter as an effective public engagement tool for science, and for politicised scientific issues in particular, is not being realised.

Scientists for whom English is not their first language report disadvantages with academic communication internationally. This case study explores preliminary evidence from non-Anglophone scientists in an Australian research organisation, where English is the first language. While the authors identified similarities with previous research, they found that scientists from non-Anglophone language backgrounds are limited by more than their level of linguistic proficiency in English. Academic science communication may be underpinned by perceptions of identity that are defined by the Anglocentric hegemony in science, which dictates not only how academic science is communicated but also who can communicate it.

In this article, we present three challenges to the emerging Open Science (OS) movement: the challenge of communication, collaboration and cultivation of scientific research. We argue that to address these challenges OS needs to include other forms of data than what can be captured in a text and extend into a fully-fledged Open Media movement engaging with new media and non-traditional formats of science communication. We discuss two cases where experiments with open media have driven new collaborations between scientists and documentarists. We use the cases to illustrate different advantages of using open media to face the challenges of OS.

In response to Weingart and Guenther [2016], this essay explores the issue of trust in science communication by situating it in a wider communications culture and a longer historical period. It argues that the popular scientific culture is a necessary context not only for professional science, but also for the innovation economy. Given that the neutrality of science is a myth, and that science communication is much like any other form of communication, we should not be surprised if, in an innovation economy, science communication has come to resemble public relations, both for science and for science-based innovations. The public can be sceptical of PR, and may mistrust science communication for this reason.

The phenomenon of lay readers of neuroscience being positively biased by the mere presence of brain images (fMRI), has been hotly debated, with recent failures to replicate the phenomenon, and suggestions that context is important. We experimentally investigated the potentially biasing effect of neuroimagery on participants' beliefs and explored an important facet of context within a neuroscience article: whether the article was supportive or critical of fMRI use in detecting states of mind. Results supported recent arguments that a “neurorealism” effect may in part be an artifact of experimental design; but we also report evidence that context may be critical.

Written in response to a previous article by Weingart and Guenther [2016] in JCOM, this letter aims to open up some critical issues concerning the ‘new ecology of communication’. It is argued that this evolving ecology needs to be openly explored without looking back to a previous idyll of ‘un-tainted’ science.

This issue of JCOM presents some interesting challenges relating to trust and the media ecology that supports science communication. Weingart and Guenther have organised a set of commentaries considering the issue of trust and media from different points of view, by asking for responses to their paper 'Science Communication and the Issue of Trust'. The commentaries focus on traditional and social media and the actors that contribute to media content, though they do not consider 'paid for' content (also known as advertising), which is the subject of a paper by Silva and Simonian also published in this issue of JCOM.

This study applies social network analysis to explore the role that one science festival has played in building the state's STEM learning ecosystem. It examines the breadth and extent of collaboration among STEM educators and their partners, reviewing past and present partnerships across 449 events during the 2015 festival. Three case studies provide in-depth illustrations of partnerships. These findings represent an important step towards (a) mapping a STEM learning ecosystem, and (b) trying to understand how a festival affects the ecosystem itself. Together, study results demonstrate how the festival has served to stimulate and foster STEM partnerships.
