Despite Mexico has coasts in the Pacific and Atlantic oceans, people's connection towards the sea and marine environments is quite poor. Our commentary focuses on Mexico's coral reefs, relevant tropical ecosystems to human and oceanic welfare, and it emerges from the experience of the production of an itinerant coral reefs exhibit in Mexico, committed to the conservation and awareness of this threatened habitat. The UN Decade of Ocean Science for Sustainable Development starts in 2021 and represents an opportunity to increase initiatives for public communication of science on marine and oceanic issues in Mexico and the world.

The medical arena often encounters ‘taboo’ topics. These appear especially prevalent in women's health conditions, such as menstruation and menopause. Taboos are exacerbated by medical uncertainty, complex jargon, and patients' misunderstanding of the human anatomy — impacting patients' ability to actively participate in a shared decision-making process with their doctor. In this commentary, we look at one example of a medical procedure where taboo topics pose a number of challenges in doctor-patient communication — hysterectomy. We explore whether science communication can address these challenges, as well as contribute and collaborate in other medical scenarios, thereby benefiting both disciplines, and ultimately, patients.

Most adults in the U.S. and worldwide claim a religious affiliation. As an element of identity and worldview, faith informs many individuals' views of science, technology, and society at large. Engagement with faith communities and religious leaders about science can improve public perceptions and trust of scientists, advance evidence-based policy, and improve diversity, equity and inclusion in science fields. This commentary outlines examples and suggests guiding principles for science engagement with faith communities.

Twelve researchers from 11 countries used autoethnographic techniques, keeping diaries over 10 weeks of the COVID-19 crisis, to observe and reflect on changes in the role and cultural authority of science during important stages of viral activity and government action in their respective countries. We followed arguments, discussions and ideas generated by mass and social media about science and scientific expertise, observed patterns and shifts in narratives, and made international comparisons. During regular meetings via video conference, the participating researchers discussed theoretical approaches and our joint methodology for reflecting on our observations. This project is informed by social representations theory, agenda-setting, and frames of meaning associated with the rise and fall of expertise and trust. This paper presents our observations and reflections on the role and authority of science in our countries from March 10 to May 31, 2020. This is the first stage of a longer-term project that aims to identify, analyse and compare changes in science-society relationships over the course of the ongoing COVID-19 pandemic.

This commentary uses a case study of Uganda and the country's attempts to adopt genetically modified organisms (GMOs) to demonstrate how activists have become communicators of scientific knowledge in the digital age. The digital age allows activists to share their information and collaborate with those who can push their agenda. I argue that anti-GMO activists have positioned themselves as influencers in a debate where weight-of-scientific evidence seems to have been overshadowed by perceptions, largely driven by socio-democratic considerations that require participation in technological uptake.

This paper identifies the diverse ways in which participants engage with science, through the same citizen science project. Using multiple data sources, we describe various activities conducted by citizen scientists in an air quality project, and characterize the motivations driving their engagement. Findings reveal several themes, indicative of participants motivations and engagement; worried residents, education and outreach, environmental action, personal interest and opportunistic engagement. The study further illustrates the interconnectivity between science communication and citizen science practices and calls for nurturing this relationship for the mutual advancement of both fields.

In this comment, we focus on the ways power impacts science communication collaborations. Following Fischhoff's suggestion of focusing on internal consultation within science communication activities, we examine the ways such consultation is complicated by existing power structures, which tend to prioritize scientific knowledge over other knowledge forms. This prioritization works in concert with funding structures and with existing cultural and social hierarchies to shape science communication in troubling ways. We discuss several strategies to address problematic power structures. These strategies may reveal and thus mitigate problems in individual collaborations, but these collaborations exist within a larger infrastructure in need of systemic change.

In this series of comments, we argue for Science Communication as an enabler of transdisciplinary, integrative collaboration in the context of today’s complex, multi-stakeholder issues. Participatory design, as a collaborative method, is effective in achieving mutual learning, shared understandings, integrating disciplines and creating solutions that make sense in the multi-layered reality of today’s challenges. Science Communication, therefore, is communication design in transdisciplinary collaborations.

In this era of pandemics, economic crises and civil unrest, science centres and museums have an opportunity to become truly relevant resources to society. This paper summarises a number of critical lessons from the PISEA International Symposium, a conference held the at the Austrian Museum of Folk Life and Folk Art in Vienna from the 17th–18th of October 2019. The purpose of this event was to share, learn, and discuss ways in which engagement with migrants and refugee populations might be improved within informal science learning spaces. Issues around integration, inclusive art-science practice, and shifting institutional policy and language were all explored. This paper also calls for the committed reform of informal science spaces, and a renewed commitment to responsive, equitable, and inclusive practice.

This special issue of JCOM features six commentary articles from the research stream of the Australian Science Communicators conference, held in February 2020. These opportunistic assessments and deliberate analyses explore important themes of trust, engagement, and communication strategy across a diverse range of scientific contexts. Together, they demonstrate the importance of opportunities to come together and share the research that underpins our practice. The conference and these commentaries enable us to engage in professional development during these exceptional times when successful evidence-based science communication is of critical significance.
