The Internet is by far the most intensely used communication tool of today and the main channel of interaction in the globalized world. This technology has opened up a whole new area for the interaction of knowledge: cyberspace, where information is always present and continuously changing. The interactivity that characterizes the virtual media together with the interactive modules developed by science centers and museums make the Internet a whole new space for the popularization of science. In order to stimulate dialog between science and society, Espaço Ciência Viva has decided to employ the Internet to divulge and to popularize scientific knowledge by bringing debates about the advances of science to the daily lives of people. To this end, its website was remodeled, which led to an increase of up to 600% in the number of visitors.

“Science on the air” is an enjoyable and extremely well researched account of the origins of science programming in north American radio. From 1923 to the mid-50s, LaFollette takes us in a journey through the life and programs of many scientists, journalists and storytellers who chosed radio as a medium for science communication. A journey who allow the reader to visit many success, but also many incomprehension and missed opportunities, mainly by scientific institutions, who often failed to understand the potential of radio as a tool for science communication. It is a fully enjoyable journey, that leave the reader with an appetite to know how the US situation relates to other wonderful experiences around the world in the same years, and how those pioneer experiences influenced today's landscape.

Science, politics, industry, media, state-run and private organisations, private citizens: everyone has their own demands, their own heritage of knowledge, thoughts, opinions, aspirations, needs. Different worlds that interact, question one another, discuss; in one word: they communicate. It is a complicated process that requires professionals «who clearly understand the key aspects of the transmission of scientific knowledge to society through the different essential communication channels for multiple organizations». The purpose of this commentary is to cast some light upon the goals, the philosophy and the organisation behind some European and extra-European Master’s degrees in science communication. We have asked the directors of each of them to describe their founding elements, their origins, their specific features, their structure, their goals, the reasons why they were established and the evolution they have seen over their history.

A recent article published in Science Communication addresses the training issue in issue in our discipline. Henk Mulder and his colleagues discuss the shared features that university curricula should or could have to favour the full admission of science communication into the academic circle. Having analysed analogies and differences in the curricula that a number of schools provide all over the world, the authors reached the conclusion that much remains to be done. Science communication seems far from having found shared fundamental references, lessons that cannot be missed in the practical-theoretical education of future professionals or researchers in this discipline. What should one study to become a good science communicator? And to make innovative research?

There is a compelling need to ensure that the points of view and preferences of stakeholders are fully considered and incorporated into natural resources management strategies. Stakeholders include a diverse group of individuals in several sectors that have an interest in how natural resources are managed. Typically, stakeholders with an interest in groundwater resources include groups who could be affected by the manner in which the resource is managed (e.g., farmers who need water for irrigation; municipalities and individuals who need drinking water, agencies and organizations that want to maintain in-stream flows to support ecosystems, etc.) Refugio County in South Texas provides an interesting case study since several groups of water users in the region are working with researchers at Texas A&M University-Kingsville (TAMUK) to develop decision-support models that incorporate stakeholder concerns. The focus of this paper is to provide a series of arguments and approaches about the ways in which stakeholder issues have recently been incorporated into environmental models, to briefly describe some of the TAMUK efforts to develop groundwater models that incorporate stakeholder inputs, and to present and discuss a method in which communication research can be used to obtain stakeholder preferences input into modeling efforts.

Mouse-related research in the life sciences has expanded remarkably over the last two decades, resulting in growing use of the term “mouse model”. Our interviews with 64 leading Japanese life sciences researchers showed heterogeneities in the definition of “mouse model” in the Japanese life sciences community. Here, we discuss the implications for the relationship between the life sciences community and society in Japan that may result from this ambiguity in the terminology. It is suggested that, in Japanese life sciences, efforts by individual researchers to make their scientific information unambiguous and explanative are necessary.

The initiatives focusing the professional development of explainers are multiplying around the world, building an informal network of researchers, museums managers and directors, explainers, and regional/continental networks, as THE group, the Thematic Human Interface and Explainers group of Ecsite.The Workshop Sul-Americano de Mediação em Museus e Centros de Ciência e Escola de Mediação em Museus e Centros de Ciência, which took place in Rio de Janeiro in September 2008, was a further important step along this path. We believe it is worthwhile to offer to Jcom readers some of the workshop contributions concerning the training of explainers, to which we added an overview of the general problem presented by Lynn Uyen Tran (Lawrence Hall of Science at the University of California, Berkeley).

In 2008 two collections were published: the Handbook of Public Communication of Science and Technology, edited by Massimiano Bucchi and Brian Trench, and Communicating Science in Social Contexts: New models, new practices, edited by Donghong Cheng and five other scholars from China, Canada, Belgium and Australia. These books try to define and draw the boundaries of science communication’s field from both a theoretical and empirical point of view. But do we need to establish it as a distinct research field? For a number of decades, a growing community of scholars and communicators is trying to reply positively to this question, but the need to look outside the disciplinary boundaries, to other academic fields, is still vital.

In a refereed journal in the food and agriculture sector, papers were tracked over a five-year period during the introduction of electronic submissions. Papers originated in the Americas and Pacific region and were processed in Canada. Acceptance times for revised papers were reduced (P < 0.001) to 59% of the original, from 156.5 ± 69.1 days to 92.8 ± 57.5 days. But the start of electronic submission coincided with a change in the geographical origin of papers, with papers from Anglophone countries changing from a 61% majority to a 42% minority. It is possible that submissions from non-Anglophone sources were facilitated, thus creating challenges to the traditional Anglophone reviewer population.

The knowledge deficit model with regard to the public has been severely criticized in the sociology of the public perception of science. However, when dealing with public decisions regarding scientific matters, political and scientific institutions insist on defending the deficit model. The idea that only certified experts, or those with vast experience, should have the right to participate in decisions can bring about problems for the future of democracies. Through a type of "topography of ideas", in which some concepts from the social studies of science are used in order to think about these problems, and through the case study of public participation in the elaboration of the proposal of discounts in the fees charged for rural water use in Brazil, we will try to point out an alternative to the deficit model. This alternative includes a "minimum comprehension" of the scientific matters involved in the decision on the part of the participants, using criteria judged by the public itself.
