We live in bewildering times. Unusual politicians and political movements are rising to the fore, geopolitical maps are being redrawn, old certainties are collapsing, and knowledge — both good and bad — is flowing differently from ever before. Based on the belief that effective communication of science requires understanding of our communication landscape, in this article I offer a brief `technological tectonics' of our current communication landscape, exploring how shifts in communication technologies have made certain politics and certain flows of knowledge possible. I then offer three paths for action — in reflection, practice and advocacy — for those interested in the communication of science.

I was invited by my colleagues, Leßmöllmann and Medvecky, to participate in a set of commentaries on the role of science communication in the post-truth era, which will be published in the Journal of Science Communication. My reflection will focus on how reshaping and promoting official or governmental science communication could help minimise the impact of misinformation on science-related issues, such as climate change, vaccines and artificial intelligence, among others, in the public sphere. Although European and Western governments have increasingly embraced the integration of science communication as a structural and ethical component of their public information strategies, these efforts have mainly centred on fostering dissemination practices led by individual researchers or research teams. However, this approach often overlooks the equally critical role of institutional communication systems, which are incapable of translating scientific knowledge into clear, accessible and actionable information for the broader public. This omission becomes particularly salient during crises when citizens actively seek guidance grounded in scientific evidence and are frequently met with institutional silence, ambiguity or poorly coordinated messaging.

Rapid and significant developments in the science of Autism Spectrum Disorders (ASDs) have provoked serious social and ethical concerns as well as positive influences worldwide. This study created a social agenda containing 21 important issues regarding the relationship between ASDs and society and the development of the science of ASDs. The agenda was constructed with the input of a variety of Japanese people who were provided with scientific ASD information and engaged in discussions regarding ASDs. First, opinions were sought via a questionnaire from the attendees of six science café sessions. Then, additional important issues were put forward by attendees of a larger dialogue session regarding the relationship between ASDs and society, again via a questionnaire. The agenda covered a wide range of issues, including information regarding ASDs, people’s understanding of ASDs, social support, education, the difference between ASD characteristics and individuality, ASD research, diagnosis, and social attitudes.

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.

From contributions of astronomy data and DNA sequences to disease treatment research, scientific activity by non-scientists is a real and emergent phenomenon, and raising policy questions. This involvement in science can be understood as an issue of access to publications, code, and data that facilitates public engagement in the research process, thus appropriate policy to support the associated welfare enhancing benefits is essential. Current legal barriers to citizen participation can be alleviated by scientists’ use of the “Reproducible Research Standard,” thus making the literature, data, and code associated with scientific results accessible. The enterprise of science is undergoing deep and fundamental changes, particularly in how scientists obtain results and share their work: the promise of open research dissemination held by the Internet is gradually being fulfilled by scientists. Contributions to science from beyond the ivory tower are forcing a rethinking of traditional models of knowledge generation, evaluation, and communication. The notion of a scientific “peer” is blurred with the advent of lay contributions to science raising questions regarding the concepts of peer-review and recognition. New collaborative models are emerging around both open scientific software and the generation of scientific discoveries that bear a similarity to open innovation models in other settings. Public engagement in science can be understood as an issue of access to knowledge for public involvement in the research process, facilitated by appropriate policy to support the welfare enhancing benefits deriving from citizen-science.

This study explores the presence of science programs on the Flemish public broadcaster between 1997 and 2002 in terms of length, science domains, target groups, production mode, and type of broadcast. Our data show that for nearly all variables 2000 can be marked as a year in which the downward spiral for science on television was reversed. These results serve as a case study to discuss the influence of public policy and other possible motives for changes in science programming, as to gain a clearer insight into the factors that influence whether and how science programs are broadcast on television. Three factors were found to be crucial in this respect: 1) public service philosophy, 2) a strong governmental science policy providing structural government support, and 3) the reflection of a social discourse that articulates a need for more hard sciences.

The importance the Brazilian government has given in the last few years to the dissemination of science points out the necessity of a more discerning analysis about the establishment of this subject on the public agenda and the related public policies undertaken. This work tries to contribute to the debate as an inquiry about the policies to popularize and disseminate Science and Technology (S&T) established by the Science and Technology Popularization and Dissemination Department, which was created in 2004. In order to do so, theoretical references from Public Policy Analysis, the Studies of Science, Technology and Society (SSTS), and Public Communication of Science are used. Furthermore, we analyze some of the results from research on Science and Technology Understanding carried out in Brazil in 2006. As a final point, this associated approach aims at identifying some of the limiting factors related to science dissemination actions in Brazil.

The major Lisbon goal is to give Europe back the primacy as a society of knowledge. `Giving back' is a more appropriate term than `giving', as Europe long held that primacy in the past, and virtually as a monopoliser from the 17th century throughout the 19th. Then, Europe shared it with North America for a long portion of the 20th century.

The first step of the SEDEC project has been a survey on teachers and pupils perception of science, scientists, and the European dimension of science. Different research actions have been organized for the different targets, and have been held in the six countries involved in the project: Czech Republic, France, Italy, Portugal, Poland and Romania. This article will present the analysis of more then 1000 drawings realized by 9 and 14 years old pupils and representing "a scientist". Form the drawings emerge stereotypes, fears, desires, expectations and more, a whole imaginery that has to be taken in account for an effective educative adn communicative action.

To design teaching materials starting from the subject matter in Science field, from the contents of textbooks or by studying the syllabuses are regular practices within schools. The SEDEC project proposes concrete and innovative modalities of conceiving teaching materials starting from teachers perception of science and by talking with them about their ideas and needs regarding teaching Science. A deep discussion of the relationships between science education and European citizenship has been another important ingredient of this new process of didactic design.
