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.”

This practice insight explores the potential of broadcast television news and current affairs programs for science communication in everyday viewing environments. Using the Japanese news program Shins¯o H¯od¯o Bankisha! as a case study, we assessed its impact on public knowledge of “blue carbon”, a relatively new scientific topic. The program aired on May 28, 2023, reaching an estimated 2.76 million viewers in the Kanto region. A survey revealed that viewers exposed to “blue carbon” through the broadcast showed significant knowledge gains compared to non-viewers, regardless of their interest in science. This included individuals with low scientific interest, a group often excluded by traditional science communication methods. Despite the rise in popularity of digital media formats, broadcast television news and current affairs programs showed their unique ability to disseminate scientific knowledge to diverse audiences, even in today’s multitasking environments. These findings highlight the enduring relevance of television in science communication and its potential to complement digital platforms for broader public engagement.

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.

Micro-patronage provides a new model of funding for research communication. This article uses the Lingthusiasm podcast as a case study to describe how micro-patronage can work and some of the benefits and challenges involved. The authors draw on their own experience of micro-patronage to demonstrate how to create sustainable projects. They also discuss how it sits alongside university funding structures, while also providing a measure of independence from those structures.

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.

Coordinated attempts to promote systematic approaches to the design and evaluation of science communication efforts have generally lagged behind the proliferation and diversification of those efforts. To address this, we founded the US National Institutes of Health (NIH) Science of Science Communication Scientific Interest Group (SciOSciComm-SIG) and undertook a mixed-methods survey-based analysis of the group one year after its founding. Respondents indicated ongoing interest and some participation in public-facing science communication while identifying specific barriers, and praised the role of the SIG in expanding access to information about evidence-based practices.

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.
