Volume 25 • Issue 5 • 2026 • Transitions in Science Communication: Continuity and Change (PCST 2025)

This editorial introduces the JCOM special issue on “Transitions in Science Communication: Continuity and Change”. The issue positions continuity and change within four historical processes that have shaped the development of the field: institutionalisation, professionalisation, internationalisation, and diversification. Within these broad field-shaping processes, the issue seeks to capture moments of transition in science communication by featuring selected contributions to the 2025 conference of the Global Network for the Public Communication of Science and Technology (PCST). The special issue combines three genres of contributions: research articles, practice insights, and an invited essay. Across these different contributions, the issue captures three types of transitions, focussed on agendas, approaches, and voices. It illustrates ongoing transitions within the institutions of science communication and transitions in professional roles and institutional responsibilities. It features contributions that show how the processes of internationalisation and diversification lead to new agendas, new approaches, and, crucially, new voices that can take science communication in new directions.

Science museums are undergoing a transition, expanding their role in science communication to engage with equity and inclusion actively. Although women and gender-diverse individuals constitute a significant proportion of museum audiences, they remain underrepresented in exhibitions and leadership roles. This study examines how science museums can address gender equity. Based on a survey of science museum professionals across Latin America and the Caribbean, we identified respondents reporting gender-focused transformative actions. We conducted a thematic analysis of gender-focused transformative actions. Five key elements were developed: female participation, identity negotiation, disruption of normative gender narratives, historical recovery, and activism. The initiatives demonstrate significant transformative potential but are constrained by persistent challenges. By examining these evolving practices in contexts shaped by both structural inequalities and historical struggles for rights, this study contributes to an understanding of how science museums can act as spaces for social transformation.

Science communication experiences major transitions: alongside science journalists, scientists, their institutions, and public relations departments increasingly select and communicate science information to publics, thereby stepping into gatekeeping roles. To better understand this “shared gatekeeping” and how different science communicators select topics, this article investigates relevance criteria that guide selection and communication decisions of science information. Drawing on 57 interviews with German-speaking science journalists, science public relations practitioners, and scientists, the study identifies and compares relevance criteria for each group based on the hierarchy of influences model. Findings reveal a wide range of relevance criteria as well as similarities and differences at individual, communication routines, organizational, and social institutional levels. Although all groups seem to be guided by similar, partly journalistic, relevance criteria (e.g., overlapping goals, topic characteristics), they operate within distinct professional contexts and thus weigh these criteria differently.

This theoretical article introduces academic saviourism as a concept that explains how inclusion efforts in science communication can at times unintentionally reproduce epistemic hierarchies, and end up being symbolic rather than transformative. Building on theories like Bourdieu's habitus, Archer et al.'s science capital, and Critical Race Studies' perspectives on the White Savior Industrial Complex, I draw out three interrelated manifestations of academic saviourism: (1) affective burdens on marginalised individuals, (2) the performative inclusion practices of science communication institutions, and (3) the underlying normative assumptions that shape how science communication actors understand marginalised communities' needs and participation.

Social media made a huge transition in science communication during the public health crises. Social media amplified the audience communication effect of popular science short videos and played a positive role in containing epidemics and stabilizing social sentiment. The purpose of this article is to investigate the effective communication and alignment mechanism of popular science short videos on social media. Applying grounded theory and combining case studies with interviews, this article investigates the factors that influence the effective communication of popular science short videos on social media platforms in China during public health crises. The research identifies audience demand, content quality, platform diversity, and media matrix integration as key factors driving effective communication during public health crises. This study attempts to thoroughly examine the communication process of popular science short videos and propose further suggestions for the future development of popular science media.

The climate crisis is no longer a crisis of knowledge, but a crisis of agency. Individuals wishing to act must overcome climate anxiety, feelings of powerlessness, and doubt associated with the complexity of the scientific realities of climate change. Rural communities offer much to learn about sustainable living and environmental solutions, but are rarely the site of many science communication initiatives due to inequities in funding, transit, and access to decision-makers. This practice insight explores how the act of performing in `We Built This City on Rock and Coal', an improvised theatre show about climate change in rural and remote communities in Ireland, supported performers to develop agency and transition towards taking pro-environmental actions in their own lives. Accessing environmental science expertise alongside space for emotional responses (both heavy and light-hearted) in specific contexts anchored by local knowledge helped practitioners create a platform for change and climate action.

Outreach on mental illness presents a unique challenge for science communication, in that it requires approaches to actively address associated stigma. A significant barrier to treatment and recovery, stigma shapes the lives of those diagnosed with mental illnesses alongside their clinical symptoms. Evidence suggests that active involvement of person(s) with lived experience (PwLE) may be a promising strategy to combat stigma. However, such interventions remain under-documented in low- and middle-income countries like India. To address this gap, we designed a series of innovative events, co-produced with PwLE. We engaged approximately 260 participants and displayed 191 creative artefacts. This article presents and reflects on our science communication practices to address mental illness stigma by integrating arts-based participation with principles from contact theory.

This state-of-the-art literature review advances the shift in science communication research towards an organisational perspective, moving focus from individual researchers' capabilities to the role of organisational structures and practices. It explores how temporary collaborative research organisations, such as research projects, organise their activities, and examines the link between organisational structuring and science communication. Offering a structured overview, the review identifies research gaps and contributes to systematising the field by proposing a conceptual framework that integrates the communicative constitution of organisations (CCO) theory with institutional approaches to science communication. The literature reveals three key organisational dimensions: contextual conditions, cooperation, and communication. In addition to previously recognised components of `organisationality' — actorhood, identity, and interconnected decision-making — contextual conditions are also shown to play a role in organising in temporary research organisations. The theoretically driven framework supports the defragmentation of the research field and provides a foundation for future inquiry.

This essay examines citizen science, from a theoretical and conceptual perspective, as an evolving field situated within emerging agendas for rights that intersect with struggles for environmental, cognitive, and data justice. It contends that citizen science is a polysemic concept, encompassing practices ranging from instrumental data collection to democratic knowledge co-production. Drawing on diverse theoretical contributions and incorporating recent debates within the participatory sciences approach, the essay foregrounds perspectives from Global South authors, particularly decolonial and anti-colonial Latin American thought. The essay explores how citizen science may either challenge or reinforce power asymmetries. On the one hand, it can amplify diverse knowledge systems, foster intercultural dialogue, and act as a form of data activism, strengthening citizenship. On the other, it risks reinforcing platform capitalism, digital surveillance, and data extraction, thereby undermining community autonomy. Cognitive justice and data sovereignty are therefore not inherent conditions of citizen science, but outcomes dependent on equitable governance arrangements, ethical protocols and safeguards, and open infrastructures.
