Protest placards are an important part of School Strike 4 Climate (SS4C) protest culture and illustrate how protesters view, understand and share their environmental concerns. Many of the placards use humor to convey the messages of their creators. Bringing together science communication and humor studies, this paper examines the communicative functions of humor in Australian SS4C posters by asking to what extent protest signs can be understood as a vehicle of science communication. The paper reveals how humorous protest placards become the means of grassroots creativity, exploring bottom-up science communication in an ambiguous, but accessible and enjoyable form.

In an increasingly mediated culture, social institutions such as science, public health, and civic engagement exist within the same modes of discourse as popular media. As a human endeavor, science is also a cultural phenomenon, and there are webs of multidirectional and layered communication that occur between formal science communication, pop science, and, indeed, popular media. For public participants, engagement with science and entertainment may be one in the same. This essay draws from research of transformative works, fan studies, and memetics to examine how the public engages with science and popular media within digital cultures.

At last, a compilation of essays that provide fascinating insights into Health Communication and Disease in Africa. Falade and Murire (eds.) have produced a volume which needed to be written and will delight those with an interest in health and science communication, public health, social and behaviour change, and theoretical approaches to health communication. Broad themes cover stigma, beliefs and traditions, and rethinking approaches to health communication. A key element is the effort to bridge ‘classical’ approaches to health communication and behaviour change with indigenous knowledge systems of people in Africa.

The latest in a growing number of edited volumes that take science communication as a phenomenon to be explored through science cultures is a rich book full of theoretical and methodological rigour. There are 17 chapters included here from 33 authors across 16 different countries containing selected paper contributions from the 2018 Science & You conference in Beijing jointly organised by the Chinese National Academy of Innovation Strategy and the University of Lorraine, France. With an opening address by Massimiano Bucchi, chapters are arranged thematically, with emphasis on the roles of institutions, state and media in the social dynamics and public understandings of science and technology across global cultures.

In December 2021, Netflix released a comedy feature film, ‘Don't Look Up’. The film follows two scientists who discover an extinction-level comet heading for Earth, which they then attempt to warn humanity about. The makers of the film have publicly stated that the film is meant as a satirical metaphor for the response to the climate emergency. The film presents representations of science, scientists, and science communication. In this set of commentaries, experts have been selected to explore these representations and the lessons the film presents for using satire in science communication.

One of the recent “crises” experienced by science is associated with a decline in its public support. We conducted two factorial surveys among university students aiming at broadening our understanding of the information cues influencing the wider publics' judgments of science. We found that sociological and criminological research results are perceived as less plausible compared to neuroscientific and physiological research, but as more plausible than results from genetics. In contrast with the previous data on the importance of funding and institutional prestige cues as the indirect indicators of the research quality among academic experts, we discovered the absence of any effects of funding or institutional prestige for the selected type of general audience.

Science communication is at the heart of many of the challenges our societies face today. At the same time, on-going changes in the relationship between science and society and the digitalisation of society can make science communication itself into a complex challenge. How can science communication adapt to an ever-changing landscape and take on new roles? In this issue we explore the potential of ‘responsible science communication’ to support and develop meaningful, open and trustworthy relationships between science and society. We present a selection of papers that review three crucial dimensions of ‘responsible science communication: reflexivity, inclusivity and co-creation’. Integrating theory and practice, this issue advocates that researchers and practitioners should be mindful of these dimensions to create meaningful conversations about science and our future.

Citizen Science (CS) can help change the paradigm of science communication. To test this, 38 ongoing CS projects from Italy, Portugal and Spain have been selected by the H2020 NEWSERA project to act as pilots in the development of communication strategies, specifically targeting stakeholders in the quadruple helix. The projects, together with stakeholder representatives and science communication and journalism professionals participated in a series of workshops — #CitSciComm Labs — where communication strategies were co-designed, using adapted design-thinking methods. The innovative methodological approach is hereby presented and can be an inspiration for others willing to implement improved communication strategies to target different stakeholders.

Both research and anecdote in science communication suggests that it is a field where women feel ‘at home’, with high numbers of women science communicators and students on training programmes, but why might this be the case? Using data gathered from a survey of 459 science communicators based in Italy, the Netherlands, Poland, Portugal, Serbia, Sweden and the U.K., we examine the perspectives of female science communicators, in terms of working practices, motivations and barriers to communicate.

The Polish science communication field has grown into a robust and diverse community. Centralised and governmentally funded initiatives are complemented by more bottom-up actions led by academia, researchers, journalists and educators. Still, the main goals of science communication in Poland seem to be a diffusion of scientific knowledge and building trust towards science and scientist. The concept of openness and reflexivity could help to include the needs and perspectives of non-scientific audiences into science communication practice in Poland.
