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.

To give a good public speech is art; but definitely more difficult is to organize a productive exchange of points of views between scientists, experts, non-experts and policy-makers on controversial issues such as a scenario workshop or a consensus conference. Many skills and a deep knowledge both of the topic and of the methodology are required. But this is the future of science communication, a field where the dialogical model will impose new and complex formats of communication and a new sensibility, using also the most traditional media. But are science communicators prepared for that? What is the state of the art of science communicator training?

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.

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.

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.

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 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».

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.

In 2007, global investments in R&D have increased by 7% on the previous year and have reached an absolute historical peak, exceeding for the first time the threshold of 1,100 billion dollars (calculated in the hypothesis of a purchasing power parity between the currencies). The world invests in scientific research and technological development 2.1% of the wealth it produces. At the same time, there has been an increase in the exchange of high added-knowledge value goods and high tech represents now the most dynamic sector of the world economy.

This article will briefly present a few theses and reflections of mine on some perversions and disruptions under way in knowledge development and in science representation. Nevertheless, I will abstain from exposing thoroughly the obvious and triumphal side of the coin. Namely, I am not going to extol the amazing fortune of science and knowledge, which have become the fundamental resource for development, at economic level in first place. Indeed, having reached a certain age, I can allow myself ­ although to a certain degree of oversimplification ­ less enthusiasm and a few old-fashioned ideas.
