Who speaks for “citizen science” on Twitter? Which territory of citizen science have they made visible so far? This paper offers the first description of the community of users who dedicate their online social media identity to citizen science. It shows that Twitter users who identify with the term “citizen science” are mostly U.S. science professionals in environmental sciences, and rarely projects' participants. In contrast to the original concept of “citizen science”, defined as a direct relationship between scientists and lay participants, this paper makes visible a third category of individual actors, mostly women, who connect these lay participants and scientists: the “citizen science broker”.

When it comes to complex topics in the field of health and risk communication, experts are of high importance for the credibility of a news media report. This paper examines the use of experts and their roles in the news media coverage of multi-resistant pathogens by means of a quantitative content analysis of German print and online news. A cluster analysis of the expert statements identifies three different statement frames describing different expert roles. The results show manifest patterns of selected expert sources, which points to professionalized mechanisms of selecting expert sources for news media reports.

In recent times we have allegedly witnessed a “post-truth” turn in society. Nonetheless, surveys show that science holds a relatively strong position among lay publics, and case studies suggest that science is part of their online discussions about environmental issues on social media — an important, yet strikingly under-researched, debate forum. Guided by social representation theory, this study aims to contribute knowledge about the role of science in everyday representations of livestock production on social media. The analysis identifies two central themata, namely lay publics' contestations of (1) facts and non-facts, and (2) factual and non-factual sources.

This research develops a conceptual framework for telling visual stories about science using short-format videos, termed SciCommercial videos, that draw upon marketing communication. The framework is illustrated by an exemplar, the Good Whale Watching video, which is explained using a visual rhetoric keyframe analysis. Finally, the effectiveness of the video is evaluated as a science communication tool using an empirical online survey with 1698 respondents. The results highlight the benefits of using video for storytelling about science by using our framework formula, modified from marketing practices, to produce videos that are Simple, Unexpected, Concrete, Credible, Emotional, Science Storytelling (SUCCESS).

This comment discusses feminization of science communication as a process that is related to the professionalization of the field, but also with the subordination of its practices to certain ideas of science that have described as androcentric. It argues that science communication can play an important role in questioning this subordination and contributing to democratizing science bringing gender diversity into it. For this, the comment presents the case of a Colombian transgender scientist whose public presence in media has being important to destabilize scientific subjectivities in the country and also has opened the possibility to think of science from a care-ful perspective.

Science and technology have become tools to legitimize messages that affect the world in terms of society, politics and economy. This paper presents part of the results of a study that analyzed the symbolic construction of the future in the scientific-technological discourse at EPCOT theme park in Orlando, Florida. The sociohistorical conditions and narrative strategies are analyzed based on the theoretical and methodological approach by John B. Thompson. The results highlighted that the construction of the notion of progress is strongly influenced by the commercial and political interests of the sponsors. In particular, the ‘Test Track’ ride totally lacks any discussion about the impact of cars on society and the environment. The future is presented as a utopian one without any possible disruption, a perception that permeated the development of the United States over the 20th century and is promoted even in the 21st century despite the evidence provided by multiple wars and crises.

In early August 2019, the U.S.A. saw 2 significant mass shootings in just 48 hours. On Twitter, Neil deGrasse Tyson responded with a tweet to his millions of followers. He outlined the number of deaths in 48 hours from other causes, and seemed to disparage the human tendency to respond emotionally “more to spectacle than to data”. The tweet resulted in an uproar. This “twitterstorm” might provide important lessons for practicing science communicators. The first lesson outlined in this letter is about the use of analogy in science communication, and the second is about how emotion is addressed in science communication.

Fiction is often credited with shaping public attitudes to science, but little science communication research has studied fans' deep engagement with a science-themed fiction text. This study used a survey to investigate the impacts of television series ‘Doctor Who’ (1963–89; 2005–present) on its viewers' attitudes to science, including their education and career choices and ideas about science ethics and the science-society relationship. The program's reported impacts ranged from causing participants to fact-check ‘Doctor Who’'s science to inspiring them to pursue a science career, or, more commonly, prompting viewers to think broadly and deeply about science's social position in diverse ways.

The research explores the differential impact of exposure to one-sided vs. two-sided satire about climate change on message processing. Analyzing experimental data (N =141) we find that one-sided satire offered by ‘The Onion’ ironically claiming that global warming is a hoax encourages viewers to engage in greater message elaboration and counterarguing. In contrast, two-sided satire offered by ‘The Weather Channel’ that makes jokes about those who believe in vs. reject human involvement in climate change is quickly discounted. We conclude by discussing the strategic value of incorporating one-sided satirical humor in communication efforts focused on climate change engagement.

Research shows that news consumption plays a positive role in youths' environmental engagement. This article examines if this also holds true for sceptics by comparing Swedish climate change sceptics with non-sceptical youngsters in their early and late adolescence. We conceptualise news consumption as foci of public connection and orientation rather than a source of environmental information. The results show that in their early teens, heavy news consumers among both sceptics and non-sceptics are indeed more engaged with environmental issues than their less news-oriented peers. However, in late adolescence, sceptics among news consumers show very little environmental engagement.
