From ‘Feed the Birds’ to ‘Do Not Feed the Animals’ takes an engaged approach in which science communication is both process and outcome of the research. The project started in the UK in March 2020, coinciding with government-imposed lockdowns in response to the COVID-19 pandemic; since the project’s engagement had been designed around in-person interactions, a rapid and creative rethink was needed. This paper outlines the redesign of the project and describes a hybrid model of on-line and in-person engagement, integrating new skills and technologies which the pandemic catalysed, with well-established in-person practice in science communication. Our research develops good practice for online, participatory science communication, and supports the advancement of engaged research more widely.

Participatory science communication featured in several sessions and individual papers at the 2021 online conference of the Public Communication of Science and Technology (PCST) Network. This coverage recognises the drive away from linear communication to more participatory forms of science communication. In this special edition we present practice insights, papers and essays that explore participatory science communication. These contributions explore definitions, processes and describe case-studies of participatory science communication which involve a variety of publics, from young school students to Indigenous groups to farmers. In this introductory editorial we reflect on the papers, describe the growth of a participatory approach as part of the continuing evolution of science communication; explore a definition for participatory science communication; and consider some of the key concepts and issues that emerged.

The language of science communication has moved from deficit to dialogue and talk of a ‘new social contract’ with the public ‘invited to participate’. This paper outlines a practitioner path that begins with storytelling and moves to a more participatory mode of practice of science communication for adaptation to climate change at the community scale. I outline personal practitioner reflections, specifically the need to consider issues of power, place, pain and the need to challenge assumptions. I propose the need to consider context, many forms of local knowledge and expertise, social learning, plus the pain of historical, contemporary or projected loss.

Although research has been performed on participatory mechanisms in science and technology such as brokering, little seems written on intermediary organizations, e.g. science museums, taking up and embedding a participation brokerage role and systemic factors influencing these. This paper presents a qualitative case study in which six different intermediary organizations developed their participation brokerage role in a European RRI project. We demonstrate how structuring factors in the project context, the intermediary organization and the broader systemic context influenced the participation brokerage role take-up and embedding. Our findings yield implications for future capacity building endeavors among participation brokers in the making.

Undertaking citizen science research in Public Health involving human subjects poses significant challenges concerning the traditional process of ethical approval. It requires an extension of the ethics of protection of research subjects in order to include the empowerment of citizens as citizen scientists. This paper investigates these challenges and illustrates the ethical framework and the strategies developed within the CitieS-Health project. It also proposes first recommendations generated from the experiences of five citizen science pilot studies in environmental epidemiology within this project.

Co-created citizen science offers practical tools for implementing science communication theories by increasing public participation in scientific research, empowering communities and advancing situated scientific knowledge. However, delivering such an approach presents a number of key challenges around funding, fostering working partnerships between scientists and citizens and ensuring all stakeholders receive sufficient benefits from the process. In this essay we draw from science communication and citizen science literature to describe these challenges and discuss the opportunities that will enable co-created practices to prosper.

A Science Shop acts as a mission-oriented intermediary unit between the scientific sphere and civil society organizations. It seeks to facilitate citizen-driven open science projects that respond to the needs of civil society organizations and which, typically, include students in the work process. We performed a thematic analysis of a systematically selected literature on Science Shops to understand how the scientific literature reflects the historical evolution of Science Shops in different settings and what factors the literature associates with the rise and fall of the Science Shop. We used the PRISMA methodology to search for scientific papers in indexed journals in eight databases published in English, French and Spanish, and employed the thematic theory approach to extract and systematize our results. Twenty-six scientific articles met the inclusion criteria. We identified three meta-categories and ten sub-topics which can serve as key pointers to guide the set-up and future work of Science Shops. Our results identify a major paradox: Science Shops incorporate public values in their scientific agendas but have difficulties sustaining themselves institutionally as they do not fit the current dominant research paradigm. Science shops represent a persuasive complementary approach to the way science is defined, executed and produced today.

A new regime of science production is emerging from the involvement of non-scientists. The present study aims to improve understanding of this phenomenon with an analysis of 16 interviews with Spanish coordinators of participatory science practices. The results indicate a majority of strategic and captive publics and point to communication as a key tool for the development of successful practices. Five key elements of the degree of integration required to develop a citizen participation in science practice were analysed: derived outputs, level of participant contribution, participation assessment, practice replicability, and participant and facilitator training. Proposals for strategies to remove barriers to citizen participation are the study's principal contribution.

The COVID-19 pandemic was the most prominent feature in the media in 2020. This research analyzes the scientific community's perception of the journalistic coverage of the pandemic in the Spanish media. Based on a survey with the participation of 818 respondents, the study revealed that scientists believe that radio did the best job in reporting the pandemic, whereas television did the worst. Among our findings, it is worthwhile to mention that — according to scientists — the media used sensationalistic tones and reports were not particularly accurate nor realistic. Finally, we included the scientific community's recommendations to treat the subject more appropriately.

For many decades, NGOs and social movements have acted as “alternative” science communicators. They have made strategic use of science to promote their ideological stances, to influence political and/or economic decision-making and to motivate civic action. To date, however, our understanding of science communication in activism has received little critical attention. This set of commentaries acts as a starting point for further research and reflection. The different cases and perspectives urge readers to consider the impact, democratic legitimacy, and relevance of alternative science communication, and the challenges that alternative science communicators pose for science communication and society.
