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.

Those studying the public understanding of science and risk perception have held it clear for long: the relation between information and judgment elaboration is not a linear one at all. Among the reasons behind it, on the one hand, data never are totally “bare” and culturally neutral; on the other hand, in formulating a judgment having some value, the analytic component intertwines – sometimes unpredictably – with the cultural history and the personal elaboration of anyone of us.

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.

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.

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.

Science musums and science centres are wonderful places to host, support and mediate the dialogue between science and society. In fact, they are a natural crossroad where scientists, general public, media and insitutions for formal and informal learning meet. During the recent political and health crisis concerning the rubbish treatment in the Italian region of Campania, the science centre "Città della Scienza" has promoted an unusual dialogue between citizens and scientists.

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.

This article offers a 1953-present day review of the models that have popularised DNA, one of the fundamental molecules of biochemistry. DNA has become an iconic concept over the 20th century, overcoming the boundaries of science and spreading into literature, painting, sculpture or religion. This work analyses the reasons why DNA has penetrated society so effectively and examines some of the main metaphors used by the scientists and scientific popularisers. Furthermore, this article, taken from the author's PhD thesis, describes some recent popularisation models for this molecule.

The overseas internship programme offered at Tokyo Institute of Technology as part of the science communication curriculum is highly significant, as it prompts graduate students to acquire new skills and awareness levels, including an enhanced meta-level understanding of the importance and complexity of human communications. The capacity to correlate and respond on-site in human interaction can be gradually cultivated during the internship as students experience diverse communication environments. Moreover, the exposure to different organisational, cultural and social environments helps develop a more international outlook. As a result of the initial experience described in this paper, TiTech has adopted internships as an important part of the educational tool-kit to produce scientists and engineers who can play an active role at the global level using their acquired technical knowledge and broad practical capabilities.

Dialogical models in science communication produce effective and satisfactory experiences, also when hard sciences (like astrophysics or cosmology) are concerned. But those efforts to reach the public can be of modest impact since the public is no longer (or not sufficiently) interested in science. The reason of this lack of interest is not that science is an alien topic, but that contemporary science and technology have ceased to offer a convincing model for the human progress.
