This article describes an example of science engagement striving for social justice by invigorating neglected spaces. The pop-up science centre “Knowledge◦Room“ in Vienna encourages learning, participation and engagement and provides accessibility to different groups regardless of their background. Based on a case-study of a bottom-up event at the Knowledge◦Room, we show how science communication can create a trust-based connection with disadvantaged groups in society and inspire their curiosity in science. We argue that science communication can be used as a tool for advancing social justice in the wider sense and facilitate encounters between diverse groups within society.

Twelve researchers from 11 countries used autoethnographic techniques, keeping diaries over 10 weeks of the COVID-19 crisis, to observe and reflect on changes in the role and cultural authority of science during important stages of viral activity and government action in their respective countries. We followed arguments, discussions and ideas generated by mass and social media about science and scientific expertise, observed patterns and shifts in narratives, and made international comparisons. During regular meetings via video conference, the participating researchers discussed theoretical approaches and our joint methodology for reflecting on our observations. This project is informed by social representations theory, agenda-setting, and frames of meaning associated with the rise and fall of expertise and trust. This paper presents our observations and reflections on the role and authority of science in our countries from March 10 to May 31, 2020. This is the first stage of a longer-term project that aims to identify, analyse and compare changes in science-society relationships over the course of the ongoing COVID-19 pandemic.

This commentary uses a case study of Uganda and the country's attempts to adopt genetically modified organisms (GMOs) to demonstrate how activists have become communicators of scientific knowledge in the digital age. The digital age allows activists to share their information and collaborate with those who can push their agenda. I argue that anti-GMO activists have positioned themselves as influencers in a debate where weight-of-scientific evidence seems to have been overshadowed by perceptions, largely driven by socio-democratic considerations that require participation in technological uptake.

This paper identifies the diverse ways in which participants engage with science, through the same citizen science project. Using multiple data sources, we describe various activities conducted by citizen scientists in an air quality project, and characterize the motivations driving their engagement. Findings reveal several themes, indicative of participants motivations and engagement; worried residents, education and outreach, environmental action, personal interest and opportunistic engagement. The study further illustrates the interconnectivity between science communication and citizen science practices and calls for nurturing this relationship for the mutual advancement of both fields.

In this comment, we focus on the ways power impacts science communication collaborations. Following Fischhoff's suggestion of focusing on internal consultation within science communication activities, we examine the ways such consultation is complicated by existing power structures, which tend to prioritize scientific knowledge over other knowledge forms. This prioritization works in concert with funding structures and with existing cultural and social hierarchies to shape science communication in troubling ways. We discuss several strategies to address problematic power structures. These strategies may reveal and thus mitigate problems in individual collaborations, but these collaborations exist within a larger infrastructure in need of systemic change.

In this series of comments, we argue for Science Communication as an enabler of transdisciplinary, integrative collaboration in the context of today’s complex, multi-stakeholder issues. Participatory design, as a collaborative method, is effective in achieving mutual learning, shared understandings, integrating disciplines and creating solutions that make sense in the multi-layered reality of today’s challenges. Science Communication, therefore, is communication design in transdisciplinary collaborations.

In this era of pandemics, economic crises and civil unrest, science centres and museums have an opportunity to become truly relevant resources to society. This paper summarises a number of critical lessons from the PISEA International Symposium, a conference held the at the Austrian Museum of Folk Life and Folk Art in Vienna from the 17th–18th of October 2019. The purpose of this event was to share, learn, and discuss ways in which engagement with migrants and refugee populations might be improved within informal science learning spaces. Issues around integration, inclusive art-science practice, and shifting institutional policy and language were all explored. This paper also calls for the committed reform of informal science spaces, and a renewed commitment to responsive, equitable, and inclusive practice.

This special issue of JCOM features six commentary articles from the research stream of the Australian Science Communicators conference, held in February 2020. These opportunistic assessments and deliberate analyses explore important themes of trust, engagement, and communication strategy across a diverse range of scientific contexts. Together, they demonstrate the importance of opportunities to come together and share the research that underpins our practice. The conference and these commentaries enable us to engage in professional development during these exceptional times when successful evidence-based science communication is of critical significance.

We present a novel approach to communicating abstract concepts in cosmology and astrophysics in a more accessible and inclusive manner. We describe an exhibit aiming at creating an immersive, multisensory metaphorical experience of an otherwise imperceptible physical phenomenon — dark matter. Human-Computer Interaction experts and physicists co-created a multisensory journey through dark matter by exploiting the latest advances in haptic and olfactory technology. We present the concept design of a pilot and a second, improved event, both held at the London Science Museum, including the practical setup of the multisensory dark matter experience, the delivery of sensory stimulation and preliminary insights from users' feedback.

This essay explores the relationship of science communication and public relations and contends that science communication has something to learn from public relations research. I provide an alternate history of public relations, drawn from the history of social movements (activism). I outline two areas from public relations theory: first, notions of human agency and equity in communication and, second, public interest in public communication. In doing so, I highlight how research from critical public relations could contribute to science communication efforts to enable participation with science and technology from wider, more diverse publics.
