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 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.

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.

How a discipline's history is written shapes its identity. Accordingly, science communicators opposed to cultural exclusion may seek cross-cultural conceptualizations of science communication's past, beyond familiar narratives centred on the recent West. Here I make a case for thinking about science communication history in these broader geotemporal terms. I discuss works by historians and knowledge keepers from the Indigenous Australian Yorta Yorta Nation who describe a geological event their ancestors witnessed 30,000 ybp and communicated about over generations to the present. This is likely one of the oldest examples of science communication, warranting a prominent place in science communication histories.

Feminist technoscience theory offers perspectives for science communication that both question common narratives and suggests new narratives. These perspectives emphasize issues of ethics and care often missing from science communication. They focus on questions of what is marginalized or left out of stories about science — and encourage us to make those absences visible.

The challenge to the science communication field put forward by Bruce Lewenstein, of the sector becoming a ‘ghetto’ of women's over-representation (see the commentary by Lewenstein in this issue), is a very timely wake-up call. This Commentary however, elaborates and frames the pivotal and constructivist premises on which this phenomenon should be interrogated and understood on many levels. It is critical that we undertake a deeper introspection, beyond just simplistic head counts of the number of women and men in the field, if we are to make sense of the seeming paradoxes that pervade the field, across the intersectionalities of gender, race, social class and other paradigms of inequality. This Commentary also highlights with qualitative and quantitative data how the interrogation of these developments in the field should bring on board inclusive global and diverse regional perspectives, critiques, good practices and nuances, to fully inform our shared understandings, and engender transformation in the field.

As science communication develops as a field of both practice and research, it needs to address issues of equity, diversity, and inclusion across a wide range, including race, power, class, gender. Doing so will require deeper understanding of conceptual work and practical activities that address those issues. This brief comment introduces a series of commentaries that provide one approach: feminist approaches to science communication.

Science Hunters is an outreach project which employs the computer game Minecraft to engage children with scientific learning and research through school visits, events, and extracurricular clubs. We principally target children who may experience barriers to accessing Higher Education, including low socioeconomic status, being the first in their family to attend university, and disability (including Special Educational Needs). The Minecraft platform encourages teamwork and makes science learning accessible and entertaining for children, irrespective of background. We employ a flexible approach that adapts to the needs of the users. More than 8000 children have been engaged in the first four years, with overwhelmingly positive feedback.

Effective classification of large datasets is a ubiquitous challenge across multiple knowledge domains. One solution gaining in popularity is to perform distributed data analysis via online citizen science platforms, such as the Zooniverse. The resulting growth in project numbers is increasing the need to improve understanding of the volunteer experience; as the sustainability of citizen science is dependent on our ability to design for engagement and usability. Here, we examine volunteer interaction with 63 projects, representing the most comprehensive collection of online citizen science project data gathered to date. Together, this analysis demonstrates how subtle project design changes can influence many facets of volunteer interaction, including when and how much volunteers interact, and, importantly, who participates. Our findings highlight the tension between designing for social good and broad community engagement, versus optimizing for scientific and analytical efficiency.

This paper describes community engagement activities with indigenous heritage and archaeology research in the Caribbean. The practice of local community engagement with the archaeological research process and results can contribute to retelling the indigenous history of the Caribbean in a more nuanced manner, and to dispel the documentary biases that originated and were perpetuated from colonial times. From the conception of the ERC-Synergy NEXUS 1492 research project, a key aim has been to engage local communities and partners in the research process and collaboratively explore how the research results can be positively incorporated in contemporary cultural heritage. In the context of community engagement with scientific research, this paper explores the question of who represents a community and highlights key examples in community participation in archaeological research. These examples emphasize participation throughout the research process, from the development of research questions, to data analysis, dissemination and conservation action.
