Stem cell research and therapies have been the topic of hype in the news media in Europe, America, Asia and the Pacific. Using a computational approach, we examine stem cell hype in the news media in the unique political, media and cultural context of Vietnam. The results indicate a pattern of the news media portraying this medical advancement as a source of national pride and achievement to tap into consumers' patriotism. The computational frame analysis method was shown to be efficient, helpful, and useful when researchers are confronted with urgent social, technological or public health matters. Findings from this study suggest that there is a need for national and international efforts to investigate news media content that misrepresents the current stage of stem cell treatment efficacy and risks.

This research investigates how members of the geoscience community in Portugal perceive and engage in science communication, identifying distinct patterns and practitioner profiles. Statistical analysis and a clustering algorithm were used to identify communication patterns based on practitioners' communication goals, target audiences, training, and self-efficacy. The results align with expected patterns but provide new empirical evidence of the relationship between communication goals and audience targeting, offering specific data for the geoscience community.

Extending previous research on how science fiction viewing and science news use predict attitudes toward a range of emerging technologies, this study draws on theories of genre-specific cultivation and narrative transportation to analyze how media consumption predicts attitudes toward two speculative technologies: mind uploading and terraforming. Results from a survey of the U.S. public (N = 1,015) show that science fiction viewing was positively related to support for mind uploading, while science fiction transportation was positively related to support for terraforming, belief that people are likely to develop mind uploading, and belief that people are likely to develop terraforming. Transportation also mediated relationships between science fiction viewing and attitudes. In addition, science news use was positively related to support for each technology and belief that people are likely to develop each technology. These findings highlight the potential role of media factors in predicting attitudes about hypothetical technologies.

Previous research has suggested that incorporating emotional language and exemplars within inoculation messages could enhance their effectiveness in inducing resistance to climate change misinformation. We conducted a between-subject experiment with four conditions (negative narrative inoculation, positive narrative inoculation, didactic inoculation, and misinformation only condition) to test the effectiveness of inoculation. We found that didactic inoculation increased perceived threat significantly more than both types of narrative inoculations. However, there were no significant differences across these three types of inoculation messages in conferring resistance to misinformation regarding counterarguing against misinformation, belief in misinformation, perceived credibility of misinformation, or intention to share misinformation.

Metaphors are prevalent in environmental science communication, because they describe complex topics in more familiar terms. Yet, little research has investigated whether metaphors contribute to comprehension in such communication. This experiment (N=510) disentangles the effects of different metaphor types on comprehension-related outcomes for three environmental concepts (greenhouse effect, carbon footprint, greenwashing). Results showed small but statistically significant effects of some metaphors on perceived text comprehensibility and perceived comprehension, but no effects on actual comprehension. No mediation effects were attested. Science communication could thus benefit from metaphor, but communicators should be careful not to overdo it, nor to overestimate its effectiveness.

As a recently emergent issue, public familiarity with orbital debris is likely low, and therefore especially susceptible to the influence of news media representations. To better understand media representations of orbital debris issues, a content analysis of all orbital debris news articles (N = 207) across four major U.S. media outlets (2011 – 2022) was conducted. It examines portrayals of risks associated with orbital debris, response measures, and terminology choices. Despite evidence that risks to satellite services are most consequential to everyday civilians, this risk was not a leading theme in any article. Instead, risks associated with falling debris to Earth was the most frequent leading theme across all news outlets. We also found differences across partisan outlets, including greater attention to space sustainability/safety risks and mitigation in a liberal outlet compared with a conservative outlet. Linguistically, the more colloquial “space junk” was more prominent than the more jargon-y “orbital debris.”

Visitors to public science events (PSEs) often report gains in scientific knowledge, improved attitudes toward science, and a greater awareness of science in everyday life (Jensen & Buckley, 2012; Adhikari et al., 2019; Boyette & Ramsey, 2019). However, these visitors disproportionately come from white, well-educated backgrounds (Bultitude, 2014; Kennedy et al., 2018; Adhikari et al., 2019; Nielsen et al., 2019). This paper utilizes a science capital framework to analyze the differential patterns of participation among PSE audiences. Quantitative analysis approaches are used to explore the kinds of science capital that visitors bring to PSEs, how the science capital of audiences differs between events, and how science capital might predict future participation in PSEs. Results reveal that PSE visitors typically have high pre-existing levels of science capital and that those with high levels of science capital are more likely to express interest in attending future PSEs. Directions for future research and practice are discussed.

In May 2021, the World Health Organization announced a new naming system for SARS-CoV-2 variants intended to replace potentially stigmatising names referencing geographic locations. A quantitative content analysis was conducted to identify the names and frames present in Australian news media coverage before and after the new names were announced. Results demonstrate uptake of the new names but also indicate the potential for intended outcomes of de-stigmatisation to be compromised, particularly by persistent negative framing. These findings indicate that future health communication efforts might be strengthened by integrating disease naming considerations into ongoing public health preparedness efforts and support ongoing scholarly inquiry into naming and framing in news media communication.

Movements opposing genetically modified organisms (GMOs) remain one of the most impactful protest movements in recent times, successfully suppressing the widespread global acceptance of GMOs through strategically crafted anti-GMO rhetoric. Yet, inadequate research has focused on the arguments used by GMO-promoting advocates. In this media content analysis study, inspired by the Neo-Aristotelian Method of Rhetorical Criticism (NAMRC), we analyze news articles about GMO technologies gathered from the most-read news portals in Ghana. We identify the rhetorical strategies used by GMO-promoting institutions that are reported in media interactions when the legitimacy of these technologies is questioned. We found that pro-GMO rhetoric focuses on themes of problem-solving technology, defensive advocacy, hope for the future, and scientific evidence to persuade publics. In the media coverage we analyzed, pro-GMO advocates defended both the safety of the technology and the legitimacy of scientific research and agricultural innovation. To ensure that advocacy for genetically modified crops is both responsible and credible, advocates of GMO technologies must strike a balance between conveying enthusiasm for these technologies and exercising caution about their limitations.

The COVID-19 pandemic exposed media professionals to the complex challenge of communicating scientific uncertainty. Using an automated, dictionary-based approach, we examined how different types of publications addressed scientific uncertainty at both the onset and the declared end of the pandemic. In the early stages of this health crisis, both general interest and science-focused media showed increased scientific uncertainty scores, with specialised outlets using scientific uncertainty markers more frequently. When the pandemic was declared over, science-focused publications maintained high scientific uncertainty levels across all stories, while general interest media reverted to pre-COVID-19 levels. The findings provide insights for journalists and science communicators.
