PCST 2025 took place in the silver city of Aberdeen, Scotland. Named for the sparkle of the mica in the granite of which it is largely built, Aberdeen was first scheduled to host the PCST conference in 2020, when it was cancelled due to the COVID pandemic. The conference was then hosted online in 2021, coming back to Aberdeen in person in April of 2025.

This is the age of exoplanets. Thousands of planets around other suns have been discovered, upending settled science. Unlike spectacular imagery of other phenomena (e.g., nebulae), exoplanets are difficult to `directly' image, and exoplanet scientific imagery is visually limited. This practice insight is a qualitative case study of how artists and scientists at NASA's Exoplanet Travel Bureau co-imagined exoplanets as destinations of the future, with the artists playing an essential role of clarifying and extending scientific thinking. Using textual/visual analysis of how the Bureau's iconic series of exoplanet posters (launched in 2015) invited the public to visit exoplanet landscapes, this practice insight reflects on a recent historical instance of how exoplanets were visually communicated to the public in innovative ways, using overlapping scientific and artistic practices.

Science podcasts have become an increasingly popular channel for science communication. Although podcasting has risen in popularity, little is known about why science podcasters choose to pursue this pathway for communication and how they set about achieving their goals for their podcast. Drawing on qualitative data from interviews with 20 science podcasters in Australia, our results reveal that the podcasters are mainly driven by personal factors such as their interest in, enjoyment of, and curiosity about science and that while they employ various tactics to achieve their goals, they do not consciously consider these tactics to be a form of strategic science communication.

This paper presents a practical insight based on the case study of the European Researchers' Night held in the rural village of Armamar, northern Portugal. By moving this initiative beyond traditional academic and urban settings, we helped bridge the gap between science and rural communities, and democratise access to science through a co-creation process, deep-rooted community partnerships, and active student engagement. Drawing from the RERN-Armamar blueprint, we highlight the importance of promoting and/or building from locally established networks of partners, including the school community. Local ambassadors with a diverse range of profiles can act as multipliers, engaging researchers from diverse institutions, teachers, students and their families. Context sensitive formats which promote inclusive, equitable, and sustainable access to science, in addition to the alignment of content with community interests, has further contributed to the success of the action.

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.

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.

The workshop “Decide your Print” engages high school students outside of classroom settings, with sustainability challenges, focusing on fast fashion’s socio-technical systems. Using collaborative decision-making and systemic analysis, the activity fosters understanding of sustainability’s interrelated dimensions — socio-ecological, technological, political, economic. Combining dialogue, evidence-based education and participatory approaches, it promotes critical thinking and actionable solutions. Conducted at the 2023 Genoa Science Festival in Italy, the workshop aimed to empower participants to propose multi-level strategies, showcasing the potential of informal education to address sustainability through interdisciplinary learning and systemic reasoning.

 

The mitigation of the climate crisis demands effective communication strategies. Transforming food systems plays a key role in climate protection, not only by changing eating habits, but also by preventing food waste. While workplaces are commonly used for health promotion activities, they are a rare setting for science communication. This practice insight targets individual food waste reduction through a workshop at the workplace, including a lunch from rescued food, documentary screening, discussion, and expert presentation. It aimed to enhance participants’ self-efficacy and intention to reduce food waste. The effectiveness of the screening was tested experimentally by evaluating the effects of positive and negative framing. Exposure to negative framing was associated with higher intensity in negative affect, whereas positive framing appeared to be associated with higher self-efficacy. Furthermore, this practice insight provides strategies to foster science communication in workplaces.
