While substantial research has focused on emotions within classroom activities such as class attendance, studying, and test-taking, less attention has been paid to emotional experience in informal science settings such as media, museums, and public science events. Despite their significant role, emotions are under-theorised and under-researched in science communication. However, there is a growing interest among researchers and practitioners in understanding their role in the public communication of science and leveraging these insights for more effective science communication. This context lead us to propose and organise this Special Issue on Emotions in Science Communication, comprising six manuscripts as detailed in this editorial.

Theatre is a privileged medium for expressing and conveying emotions. Emotions play a significant role in audience engagement when communicating to create awareness and knowledge about a given subject. The Marionet Theatre Company has created a series of theatre performances related to health sciences over the past few years, to expand knowledge and reduce the stigma frequently associated with certain diseases. In this report on practice, we present the process of developing the theatre performance Oxymoron, between solstices and equinoxes, exploring bipolar disorder and its consequences. The artistic team devised the performance after a series of interviews with both patients and mental health professionals. In this article, we discuss the process of its creation, identify dramaturgical connections between the performance and the interviews, and examine the emotional engagement it provoked in the audience. We conclude by assessing the effectiveness of theatre in communicating health-related subjects, most particularly by involving the audience emotionally.

Two studies, using real-time response measurement and interviews, explore how German recipients assess the trustworthiness of a voice-based communicative AI conveying science-related information with empathic and humorous expressions. In both a laboratory and an online study, humor was associated with short-term declines in trustworthiness, reflecting cultural expectations and appreciation of objectivity and neutrality. In contrast, empathic expressions are rated more trustworthy, but evoke less conspicuous effects. Cluster analysis identified four distinct patterns of evaluation, with two groups largely unaffected by affective cues and two skeptical of humor, underscoring the importance of personalization and adaptation in designing trustworthy communicative AI for science communication.

This paper uses New Zealand’s AF8 [Alpine Fault Magnitude 8] program, designed to build resilience and preparedness for earthquakes, as a real-world example to explore how emotional appeals can affect preparedness intentions within the emergency management sector. Drawing on template analysis of 14 artifacts from AF8’s communication material and 34 semi-structured interviews with emergency management stakeholders (the AF8 material’s primary audience), the study examines how emotional appeals are strategically employed and perceived in practice.  Findings contextualize theoretical understandings of how risk communication can balance fear and anxiety with positive emotions like fascination and confidence using tools such as vivid imagery, narrative framing, and certainty. The research offers empirical insights into how emotional appeals are used and perceived in risk communication, providing a foundation for developing future hazard communication strategies grounded in real-world application.

This paper uses the Aristotelian concept of pathos to investigate how scientists can persuade their audiences through emotional appeals in science crowdfunding videos (SCVs). SCVs are short videos created to promote and fund a research project through online crowdfunding platforms, and represent an emerging genre of science communication that connects experts and audiences. By adopting a linguistic and semiotic approach, a sample of 50 SCVs was analysed with qualitative analysis software to identify linguistic and non-linguistic resources that could appeal to viewers' emotions. The findings show a strong emphasis on positive emotional appeals, particularly strategies that foster kindness and friendship between scientists and audiences. In contrast, appeals to fear and pity were minimal, suggesting that SCVs focus mostly on building trust and empowering potential donors rather than evoking urgency or guilt. These results shed light on the role of emotions in science communication, particularly in the context of research funding.

This article adopts the perspective of inclusive science communication by approaching the interface between science, technology, intersectionality, and the experience of female Quilombola leaders in Minas Gerais, Brazil. Quilombolas are an ethnic-racial group of Black origins associated with oppression and resistance over the centuries, particularly against slavery during the colonial period. The primary strategy for engaging these women with science was the web series Meios de Prosa (Means of Prose), developed across three seasons. Twelve women, aged between 21 and 73, shared their experiences of early labor, racism, community leadership, and resistance in the context of their access, use, and appropriation of information and communication technologies (ICT).

While social media has been praised for youth engagement with science, evidence of its impacts remains fragmented. This scoping review reports on the impacts of social-media-based science communication on young audiences. A PRISMA-guided database search yielded 2,257 articles, which were screened to include only empirical articles studying social media’s behavioral, attitudinal, and cognitive impacts on audiences, including youth, in science or health contexts. Using Directed Qualitative Content Analysis, the impacts desired, measured, and observed were categorized in the 35 remaining articles. The most desired and measured impact was knowledge gain, while the most observed outcomes were interest and trust in science. Many studies desired specific impacts but failed to measure them. Impactful content was relevant, visually appealing, and emotionally engaging. However, studies recognized that unreliable actors may also manipulate these characteristics to spread misinformation. While many science communicators assume the importance of social-media-based science communication for young audiences, evidence of observed outcomes is limited and specific to platforms and topics.
