In recent years, citizen science has gained popularity not only in the scientific community but also with the general public. The potential it projects in fostering an open and participatory approach to science, decreasing the distance between science and society, and contributing to the wider goal of an inclusive society is being explored by scientists, science communicators, educators, policy makers and related stakeholders. The public's participation in citizen science projects is still often reduced to data gathering and data manipulation such as classification of data. However, the citizen science landscape is much broader and diverse, inter alia due to the participation opportunities offered by latest ICT. The emergence of new forms of collaboration and grassroots initiatives is currently being experienced. In an open consultation process that led to the "White Paper on Citizen Science for Europe", the support of a wide range of project types and innovative forms of participation in science was requested. In this paper we argue for mechanisms that encourage a variety of approaches, promote emerging and creative concepts and widen the perspectives for social innovation.

The prevalent lack of research on the interrelations between science, research and popular culture led to the organization of the first International Conference on Science and Research in Popular Culture #POPSCI2015, which took place at Alpen-Adria-Universität in Klagenfurt, Austria, from 17--18 September 2015. The aim of the conference was to bring together not only science communication researchers with an interest in popular culture, but also other scholars, scientists and researchers, artists, media professionals and members from the general public. In this issue of JCOM we present four invited commentaries which are all based on presentations at the conference.

The academic journal paper has been around for several hundred years and during that time has seen shifts in style and structure. This editorial explores the traditional research paper and considers whether thinking about the research paper as a story, provides insights into style and structure that would make research both more transparent and more readable.

Non-invasive prenatal testing (NIPT) is an emerging technology for detecting chromosomal disorders in the fetus and mass media may have an impact on shaping the public understanding of its promise and challenges. We conducted a content analysis of 173 news reports to examine how NIPT was portrayed in English-language media sources between January 1 and December 31, 2013. Our analysis has shown that media emphasized the benefits and readiness of the technology, while overlooking uncertainty associated with its clinical use. Ethical concerns were rarely addressed in the news stories, which points to an important dimension missing in the media discourse.

Interviews were conducted with 110 marine users to elicit their salient beliefs about recording marine species in a citizen science project. The results showed that many interviewees believe participation would increase knowledge (either scientific, the community's, or their own). While almost half of the interviewees saw no negative outcomes, a small number expressed concerns about targeting of marine species by others, or restrictions on public access to marine sites. Most of the people surveyed (n = 106) emphasised the importance of well-designed technological interfaces to assist their data collection, without which they would be unlikely to engage in the project.

Mirror neurons (MN) — or neurons said to be able to "mirror" the sensed environment — have been widely popularized and referenced across many academic fields. Yet, MNs have also been the subject of considerable debate in the neurosciences. Using a criterion based sampling method and a citation analysis, this paper examines the extent of engagement with the neuroscience literature about MNs, looking specifically at the frequency of "MN debate sources" within articles published in the JSTOR and Communication and Mass Media (CMMC) databases. After reporting the results, the paper reviews characteristic examples in context and, ultimately, shows that MN debates remain largely absent from peer-reviewed articles published in JSTOR and CMMC. However, the paper suggests that this happens for good reason and that MNs retain the potential for inventive animations even though debates have gone largely unrecognized.

Citizen science is one of the most dramatic developments in science communication in the last generation. But analyses of citizen science, of what it means for science and especially for science communication, have just begun to appear. Articles in this first of two special issues of JCOM address three intertwined concerns in this emerging field: The motivation of citizen science participants, the relationship of citizen science with education, and the implications of participation for creation of democratic engagement in science-linked issues. Ultimately these articles contribute to answering the core question: What does citizen science mean?

Citizen Science is part of a broader reconfiguration of the relationship between science and the public in the digital age: Knowledge production and the reception of scientific knowledge are becoming increasingly socially inclusive. We argue that the digital revolution brings the "problem of extension" — identified by Collins and Evans in the context of science and technology governance — now closer to the core of scientific practice. In order to grasp the implications of the inclusion of non-experts in science, the aim of this contribution is to define a role-set of non-certified knowledge production and reception, serving as a heuristic instrument for empirical clarifications.

Determined to learn the extent to which a local contaminated site was impacting community health, the Native American community of Akwesasne reached out to a research university, eventually partnering on the first large-scale environmental health community based participatory research project (CBPR). Based on interviews with scientists, community fieldworkers, and study participants, this article examines the ways in which collaborating on these studies was beneficial for all parties — especially in the context of citizen science goals of education and capacity building — as well as the challenges they faced, including communicating the limits of what scientific studies could accomplish for the community.

Since 2009 Vetenskap & Allmänhet (Public & Science, VA) coordinates an annual mass experiment as part of ForskarFredag — the Swedish events on the European Researchers' Night. Through the experiments, thousands of Swedish students from preschool to upper secondary school have contributed to the development of scientific knowledge on, for example, the acoustic environment in classrooms, children's and adolescents' perception of hazardous environments and the development of autumn leaves in deciduous trees. The aim is to stimulate scientific literacy and an interest in science while generating scientific output. The essay discusses how the mass experiments can contribute to encouraging scientific citizenship.
