Science communication continues to grow, develop and change, as a practice and field of research. The boundaries between science and the rest of society are blurring. Digitalization transforms the public sphere. This JCOM special issue aims to rethink science communication in light of the changing science communication landscape. How to characterize the emerging science communication ecosystem in relation to the introduction of new media and actors involved? What new practices are emerging? How is the quality of science communication maintained or improved? We present a selection of papers that provide different perspectives on these questions and challenges.

This paper explains how a participative approach was used to collect first-hand citizens’ suggestions on how to improve science communication regarding Climate Change. A public consultation involving citizens from 5 different European countries revealed various perspectives concerning their communication preferences on scientific topics. Five main themes emerged following citizens' proposals for better communication and involvement: producer of information, medium, message strategies, audiences and areas of action and engagement.

When analysing the actors of the science communication ecosystem, scholarly research has focused on the perceptions and attitudes of scientists, science journalists, and science communicators. How the public envisages the roles of science producers and mediators is mostly uncharted territory. We address this gap, by examining the results of a public consultation in Portugal concerning science communication. We show that the public demonstrates a clear preference for science communication performed by scientists, over journalists, although credibility and trust depend on multiple factors. We also ascertain that professional science communicators are mostly invisible, though the public recognises the value of `translators'.

Communities are rarely seen as the ideal level at which to focus science communication efforts, compared to the individual, psychological or mass, societal levels. Yet evidence from allied fields suggests building interpersonal relationships with specific communities over time is key to meaningful engagement, so orienting science communication towards communities is warranted. In this paper, we argue this case. We review previous studies, identifying three existing models of community-oriented science communication, which we label ‘neighbourly’, ‘problem-solving’ and ‘brokering’. We illustrate the effectiveness of the ‘problem-solving’ approach and the desirable ideal of ‘brokering’ using recent examples of community-oriented science communication from Australia.

In the changing science communication landscape, researchers may govern their public science-society relations through the social media connections at their fingertips. However, digital media outreach may create challenges for researchers and cause changes in the communication professionals' role. The aim of this qualitative interview study was to enhance understanding of the challenges in the rarely explored organizational collaboration between researchers and communication professionals. The results identify ambiguous duties and responsibilities, as well as blurring boundaries of occupational roles and coordination challenges in content production.

In this essay the authors reflect on some recent trends in science communication research, celebrating it as an inherently interdisciplinary endeavour. Some current tendencies in science communication are more limiting, however: they present theoretical and strategic prescriptions that do not adquately reflect the variety and cultural diversity of science communication internationally. Rethinking science communication in the context of such diverse practices and cultural reorientations, the authors revise some of their own views and revisit notions of communication as conversation to propose an inclusive definition of science communication as the social conversation around science.

Although the need to improve quality of science communication is often mentioned in public discussions, the science communication literature offers few conceptualizations of quality. We used a concept mapping approach, involving representatives of various science communication stakeholder groups working collaboratively, to propose a framework of quality. The framework organizes individual elements of quality into twelve indicators arranged into three dimensions: trustworthiness and scientific rigour, presentation and style, and connection with society. The framework supports science communicators in reflecting on their current practices and designing new activities, potentially improving communication effectiveness.

Studies on women's marginalisation as authors and sources of science stories in the media in developing countries are few, and fewer in the context of genetically modified organisms (GMOs). Using feminist media theory, this study surmises that women are accordingly underrepresented in GMO stories. Based on a content analysis of 317 stories published in two Ugandan newspapers, findings indicate that chances of females being published as authors and sources increase if they collaborate with a male. There is a need for female scientists to collaborate with male counterparts and journalists to increase their visibility in the media in an agricultural sector where women are great contributors to the labourforce.

In this essay, we explore what happens when science meets comic art and how such meeting offers an opportunity to rethink science communication. We base our discussion on our own experience, as research scholars, of engaging in a collaboration with a comic artist. Three key reflections are developed: how comic art may help to (1) conceptualize ideas in an early research phase, (2) clarify the main argument by making the (un)written word visible; and (3) communicate science with an open end. These aspects contribute to an increased understanding of science communication in both research and society.

Digital citizen science projects differ greatly in their goals and design. Tensions arise when coordinators' design choices and conceptions of citizen science conflict with users' motivations and expectations. In this paper, we use a combination of qualitative methods to gain new insights into the ways citizen science is understood and implemented digitally. This includes a study into the affordances of two citizen science portals for bird observations, and qualitative interviews with users and coordinators of the portals. This reveals tensions related to data sharing, community hierarchies, and communicated expectations. Awareness of these tensions can benefit the future design of online citizen science projects.
