From the life sciences to the physical sciences, chemistry to archaeology, the last 25 years have brought an unprecedented shift in the way research happens day to day, and the average scientist is now simply awash in data. This comment focuses on the integration and federation of an exponentially increasing pool of data on the global digital network. Furthermore, it explores the question of the legal regimes available for use on this pool of data, with particular attention to the application of “Free/Libre/Open” copyright licenses on data and databases. In fact, the application of such licenses has the potential to severely restrict the integration and federation of scientific data. The public domain for science should be the first choice if integration is our goal, and there are other strategies that show potential to achieve the social goals embodied in many common-use licensing systems without the negative consequences of a copyright-based approach.

“Web 2.0” is the mantra enthusiastically repeated in the past few years on anything concerning the production of culture, dialogue and online communication. Even science is changing, along with the processes involving the communication, collaboration and cooperation created through the web, yet rooted in some of its historical features of openness. For this issue, JCOM has asked some experts on the most recent changes in science to analyse the potential and the contradictions lying in online collaborative science. The new open science feeds on the opportunity to freely contribute to knowledge production, sharing not only data, but also software and hardware. But it is open also to the outside, where citizens use Web 2.0 instruments to discuss about science in a horizontal way.

Internet and the new media have been dramatically affecting the communication scenario. They are changing the role played by traditional media in the information processes, are creating new public spaces for dialogue and participation, and are triggering a short circuit among those producing and those receiving information. Even science communication is not stranger to the changes brought about by the new way of using and populating the web. An epitome of this process of change is the scientific podcast. This article will provide a brief review on the spreading and the purposes of podcasts in science communication, coming from a survey implemented as an activity of the course Science via podcast addressed to the second-year students of the Master in Science Communication of SISSA of Trieste.

This article presents an example of how a public science party was evaluated. The main goals of the science party, to increase the positive image of science and present an attractive science event, were evaluated in two ways. First, web surveys were used to determine the image of science before and after the event among paying visitors, invited guests, and a control group (N = 149). Second, during the event, visitors were interviewed about their experiences at the event (N = 124). The survey study showed that the image of science was very positive among all three groups of respondents. As no differences were found between pre- and post-tests, participation in the event did not lead to a more positive image of science. The results of the interviews suggested that visitors highly appreciated the event. In the Discussion, the evaluation study is analyzed and possibilities/limitations for future general use are discussed.

Will the use of the Web change the way we produce scientific papers? Science go through cycles, and the development of communication of science reflects the development of science itself. So, new technologies and new social norms are altering the formality of the scientific communication, including the format of the scientific paper. In the future, as PLoS One is experimenting right now, journals will be online hosts for all styles of scientific contributions and ways to link them together, with different people contributing to a body of work and making science more interdisciplinary and interconnected.

Science blogging is a very useful system for scientists to improve their work, to keep in touch with other colleagues, to access unfamiliar science developed in other fields, to open new collaborations, to gain visibility, to discuss with the public. To favour the building of blog communities, some media have set up networks hosting scientists' blogs, like ScienceBlogs.com or Nature Network. With some interesting features and many potential uses.

What is the meaning of “dialogue” in education? Why is dialogue important in learning processes? Tran proposes a short review of the literature, starting with Vygotsky and ending with a new field of research in informal learning - conversations among the public visiting museums as a collaborative environment for learning.

In Europe, much effort has been devoted to explore the causes of the decline in number of university matriculations of science students and to identify gender differences in career choice. Yet, the problem extends to the fulfillment of career plans: given their professional expectations and their attitudes when choosing a career, girls are much less likely to pursue scientific careers such as engineering or physics. Evidence of this is provided by the social research carried out within the framework of the GAPP project (Gender Awareness Participation Process). The Gapp project is intended to investigate differences between girls and boys in their perception of science careers and to propose a range of innovative and concrete participatory activities involving scientists, engineers and professionals from the public and private S&T sectors. In this letter, we report a synthesis of the results of the social research conducted as first step of the project: exploring how the perceptions of science professions affect interest, motivation and subject choice at school, at the university and consequently in their career.

The practice of dialogue does not erase the conflicts that can be found upon solid diverging interests. But conflicts are not forcedly a trauma. More then an impossible abolition of diversity, it is important to promote a practice that helps everybody to express their own point of view looking for socially sustainable solution between the parts. But according to Sturloni, «Even in that case: not a dialogue meant to achieve a utopian unitary view able to level all divergences, but to allow the expression of different perspectives and of legitimate interests. The final aim should be to make a choice shared as much as possible within the legal system of a democratic country».

Dialogue in science communication is a necessity - everybody agrees on it - because science and technology issues are involved in so many aspects of the citizens life, and in so many cases can raise suspects, fears, worries or, on the contrary, expectations and hopes. But who are the possible interlocutors for scientists and policy-makers? Everybody, says Luisa Massarani, beginning with children and teenagers. Also in such controversial and sensitive issues like AIDS or GMO.
