The first 18 volumes of the International Scientific Series published in both London and New York were reviewed to assess their contribution to transatlantic communication of popular science. The dominant flow of ideas was westwards on topics such as science versus religion, empiricism in psychology, survival of the fittest, jurisprudence versus mental illness, economics and development of cinematography. There was an eastward flow in philology. The preparation of volumes was rushed and many authors merely expanded previous notes, articles and pamphlets. Commercial and idealistic motives conflicted. There were disagreements among authors. Despite all this, the series had a lasting effect on social thought.

This article sums up key results of a web-based questionnaire survey targeting the members of the Danish Science Journalists' Association. The association includes not only science journalists but also other types of science communicators. The survey shows that science communicators have a nuanced and multidimensional view on science communication, science, and technology. Science communicators are thus more than the "mountain guides" of science, as a recent definition describes it. The survey respondents are not just interested in helping the public at large to a wider recognition of scientific knowledge, but also want to contribute to democratic debate and social legitimisation of science and technology. The respondents exhibit a certain amount of optimism in relation to science and technology, yet also take a sceptical stance when confronted with overly positive statements regarding science and technology. Finally they have a predominantly social constructivist perception of science and technology when it comes to external relations to society, while they lean towards a hypothetical-deductive science understanding when it concerns the internal dynamics of science

“From Earth to the Universe” (FETTU) is a collection of astronomical images that showcase some of the most popular, current views of our Universe. The images, representing the wide variety of astronomical objects known to exist, have so far been exhibited in about 500 locations throughout the world as part of the International Year of Astronomy. In the United States, over 40 FETTU exhibits have occurred in 25 states in such locations as libraries, airports, nature centers, parks and college campuses. Based on preliminary evaluations currently underway, this project – a large-scale, worldwide astronomy outreach in non-traditional locations – has unique opportunities and implications for informal science learning. We present some early findings from the observational section of the exhibit’s formal evaluation in five selected locations in the U.S. and U.K., including emphasis on inter-organizational networking, visitor attention and participant make-up as well as generative aspects of the exhibit.

This essay reflects on three figures that can be used to make sense of the changing nature of public participation in the life sciences today: outlaws, hackers and Victorian gentlemen. Occasioned by a symposium held at UCLA (Outlaw Biology: Public Participation in the Age of Big Bio), the essay introduces several different modes of participation (DIY Bio, Bio Art, At home clinical genetics, patient advocacy and others) and makes three points: 1) that public participation is first a problem of legitimacy, not legality or safety; 2) that public participation is itself enabled by and thrives on the infrastructure of mainstream biology; and 3) that we need a new set of concepts (other than inside/outside) for describing the nature of public participation in biological research and innovation today.

Online knowledge production sites do not rely on isolated experts but on collaborative processes, on the wisdom of the group or “crowd”. Some authors have argued that it is possible to combine traditional or credentialled expertise with collective production; others believe that traditional expertise's focus on correctness has been superseded by the affordances of digital networking, such as re-use and verifiability. This paper examines the costs of two kinds of “crowdsourced” encyclopedic projects: Citizendium, based on the work of credentialled and identified experts, faces a recruitment deficit; in contrast Wikipedia has proved wildly popular, but anti-credentialism and anonymity result in uncertainty, irresponsibility, the development of cliques and the growing importance of pseudo-legal competencies for conflict resolution. Finally the paper reflects on the wider social implications of focusing on what experts are rather than on what they are for.

The Makers is the latest novel of the American science fiction writer, blogger and Silicon Valley intellectual Cory Doctorow. Set in the 2010s, the novel describes the possible impact of the present trend towards the migration of modes of production and organization that have emerged online into the sphere of material production. Called New Work, this movement is indebted to a new maker culture that attracts people into a kind of neo-artisan, high tech mode of production. The question is: can a corporate-funded New Work movement be sustainable? Doctorow seems to suggest that a capitalist economy of abundance is unsustainable because it tends to restrict the reach of its value flows to a privileged managerial elite.

In this essay, I argue that the rise of personal genomics is technologically, economically, and most importantly, discursively tied to the rise of network subjectivity, an imperative of which is an understanding of self as always already a subject in the network. I illustrate how personal genomics takes full advantage of social media technology and network subjectivity to advertise a new way of doing research that emphasizes collaboration between researchers and its members. Sharing one’s genetic information is considered to be an act of citizenship, precisely because it is good for the network. Here members are encouraged to think of themselves as dividuals, or nodes, in the network and their actions acquire value based on that imperative. Therefore, citizen bioscience is intricately tied, both in discourse and practices, to the growth of the network in the age of new media.

How will peer to peer infrastructures, and the underlying intersubjective and ethical relational model that is implied by it, affect scientific practice? Are peer-to-peer forms of cooperation, based on open and free input of voluntary contributors, participatory processes of governance, and universal availability of the output, more productive than centralized alternatives? In this short introduction, Michel Bauwens reviews a number of open and free, participatory and commons oriented practices that are emerging in scientific research and practice, but which ultimately point to a more profound epistemological revolution linked to increased participatory consciousness between the scientist and his human, organic and inorganic research material.

This introduction presents the essays belonging to the JCOM special issue on User-led and peer-to-peer science. It also draws a first map of the main problems we need to investigate when we face this new and emerging phenomenon. Web tools are enacting and facilitating new ways for lay people to interact with scientists or to cooperate with each other, but cultural and political changes are also at play. What happens to expertise, knowledge production and relations between scientific institutions and society when lay people or non-scientists go online and engage in scientific activities? From science blogging and social networks to garage biology and open tools for user-led research, P2P science challenges many assumptions about public participation in scientific knowledge production. And it calls for a radical and perhaps new kind of openness of scientific practices towards society.

In this commentary, we collected three essays from authors coming from different perspectives. They analyse the problem of power, participation and cooperation in projects of production of scientific knowledge held by users or peers: persons who do not belong to the institutionalised scientific community. These contributions are intended to give a more political and critical point of view on the themes developed and analysed in the research articles of this JCOM special issue on Peer-to-peer and user-led science. Michel Bauwens, Christopher Kelty and Mathieu O'Neil write about different aspects of P2P science. Nevertheless, the three worlds they delve into share the "aggressively active" attitude of the citizens who inhabit them. Those citizens claim to be part of the scientific process, and they use practices as heterogeneous as online peer-production of scientific knowledge, garage biology practiced with a hacker twist, or the crowdsourced creation of an encyclopedia page. All these claims and practices point to a problem in the current distribution of power. The relations between experts and non-experts are challenged by the rise of peer-to-peer science. Furthermore, the horizontal communities which live inside and outside the Net are not frictionless. Within peer-production mechanisms, the balance of power is an important issue which has to be carefully taken into account.
