Social cues are used to facilitate online science communication, yet little is known about how they may play a role in online public engagement with science sites. This mixed-method study investigates r/science Ask Me Anything (AMA) sessions on Reddit through content analysis and an online survey to identify the types and variations of social cues manifested in six r/science AMAs across varying disciplines. The study's contributions are twofold. One is to investigate social cue uses in online science communication; the other is to develop a coding scheme for social cues that incorporates both positive and negative social cues in the analysis.

“Follow the science” became the mantra for responding to COVID-19 pandemic. However, for the public this also meant “follow the scientists”, and this led to uneasiness as some viewed scientists as not credible. We investigate how beliefs about the way scientists develop their findings affect pandemic-related views. Our analysis shows that beliefs about scientists' objectivity predict views regrading coronavirus-related risks, behavioral changes, and policy priorities. While political party identity also predicts views about COVID-19-related concerns, these vary by political leaders whose approaches embraced versus dismissed science-based strategies, highlighting the importance of perceptions of scientists in shaping pandemic-related attitudes and beliefs.

Physics is often perceived as difficult, but there has been little research on how physics is reported in the media. In this two-stage content analysis, we examine the portrayal of physics in five major Dutch newspapers. Results show that astronomy and astrophysics is the most prominent field. Furthermore, newspaper articles are triggered almost equally by scientific and non-scientific events. Finally, the majority of described physics concepts are framed as difficult, but journalists do provide explanations for them.

The modern science festival movement has grown significantly since the Edinburgh International Science Festival launched in 1989. Hundreds of science festivals now occur annually and vary widely. This article examines how the term “science festival” is used within research and practice. We find that most research articles fail to describe the science festivals they study. A subsequent analysis of festival websites and other publicly available information confirms the wide variability of science festival formats, which suggests the need for descriptive information about science festivals in scholarly work.

Citizen science (CS) is promoted as a useful practice for the achievement of the Sustainable Development Goals (SDGs). In this contribution we explore how CS aligns to the SDGs overarching pledge to ‘Leave no one behind’. We propose a framework to evaluate exclusionary processes in CS. We interlink three dimensions of CS inspired by existing CS typologies with five factors underpinning exclusionary processes. With this, we are able to situate existing literature on various exclusionary effects in CS within a structured framework. We hope this contribution sparks a discussion and inspires practitioners’ reflections on a more inclusive practice in CS.

In 2021 Sweden’s first national portal for citizen science will be launched to help researchers practice sustainable and responsible citizen science with different societal stakeholders. This paper present findings from two surveys on attitudes and experiences of citizen science among researchers at Swedish universities. Both surveys provided input to the development of the national portal, for which researchers are a key stakeholder group. The first survey (n=636) was exclusively focused on citizen science and involved researchers and other personnel at Swedish University of Agricultural Science (SLU). 63% of respondents at SLU had heard about citizen science (CS) prior to the survey; however a majority of these (61%) had not been involved in any CS initiative themselves. Dominant reasons for researchers choosing a CS approach in projects were to enable collection of large amounts of data (68%), improving the knowledge base (59%), improving data quality (25%), promote participants’ understanding in research (21%) and promote collaboration between the university and society (20%). The other survey (n=3 699) was on the broader topic of communication and open science, including questions on CS, and was distributed to researchers from all Swedish universities. 61% of respondents had not been engaged in any research projects where volunteers were involved in the process. A minority of the researchers had participated in projects were volunteers had collected data (18%), been involved in internal or external communication (16%), contributed project ideas (14%) and/or formulated research questions (11%). Nearly four out of ten respondents (37%) had heard about CS prior to the survey. The researchers were more positive towards having parts of the research process open to citizen observation, rather than open to citizen influence/participation. Our results show that CS is a far from well-known concept among Swedish researchers. And while those who have heard about CS are generally positive towards it, researchers overall are hesitant to invite citizens to take part in the research process.

Positioning citizen science within the broader historical public engagement framework demonstrates how it has the potential to effectively tackle research and innovation issues. Citizen science approaches have their own challenges, which need to be considered in order to achieve this aim and contribute to wider and deeper public engagement. However, programme evaluations, which discuss lessons learned in engaging the public and other stakeholders with science are rare. To address this gap, we present the H2020-funded DITOs project and discuss the use of logic models in citizen science. We share the project’s assumptions, design considerations for deeper engagement and its impact pathways demonstrating how logic models can be utilised in citizen science to monitor programme effectiveness and for their successful implementation. We hope that this work will inspire citizen science practitioners to use similar tools and by doing so, share their experiences and potential barriers. This knowledge is essential for improving the way citizen science is currently practiced and its impacts to both science and society.

Acknowledging the consolidation of citizen science, this paper aims to foster a collective debate on two visible gaps of the field. First, how to overcome the limited participation of social sciences and humanities in the broader field of citizen science, still dominated by natural sciences. Second, how to develop a citizen social science that allows for an active participation of citizens and for a critical engagement with contemporary societies. The authors coordinate a state-sponsored program of scientific dissemination within a Portuguese research institution and this paper intends to lay the groundwork for a future project of Citizen Social Science based on a new concept of “engaged citizen social science”.

WeObserve delivered the first European-wide Citizen Observatory (CO) knowledge platform to share best practices, to address challenges and to inform practitioners, policy makers and funders of COs. We present key insights from WeObserve activities into leveraging challenges to create interlinked solutions, connecting with international frameworks and groups, advancing the field through communities of practice and practitioner networks, and fostering an enabling environment for COs. We also discuss how the new Horizon Europe funding programme can help to further advance the CO concept, and vice versa, how COs can provide a suitable mechanism to support the ambitions of Horizon Europe.

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.
