Martin W. Bauer is right, two evolutionary processes are under way. These are quite significant and, in some way, they converge into public science communication: a deep evolution of discourse is unfolding, along with an even deeper change of the public understanding of science.

Science magazines have an important role in disseminating scientific knowledge into the public sphere and in discussing the broader scope affected by scientific research such as technology, ethics and politics. Student-run science magazines afford opportunities for future scientists, communicators, politicians and others to practice communicating science. The ability to translate ‘scientese’ into a jargon-free discussion is rarely easy: it requires practice, and student magazines may provide good practice ground for undergraduate and graduate science students wishing to improve their communication skills.

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.

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.

Near the turn of the Century, a woman in her 90s from Dodge City, Kansas was riding her horse near the Pecos River and she described it as a sea of saltgrasses...You had to be very close to the river to see it because the grass was so high You could drink the water out of the springs in this area. I used to ride down to the Pecos River on horseback...There was a lot more water in it back then. We grew cantaloupes...and people were amazed at how sweet they were... We stopped because the water [became] was too salty. In 1903, fresh watercress and ferns were growing at Independence Springs [on the Lower Pecos River]...and there were pools of catfish and silver bass. Residents along Independence Creek sold minnows and other bait fish they took from the river. We had a terrible flood in 1941 and 1942 which breached Zimmerman Dam. The river at some places was 10 miles wide. Floodwater covered the valley and the dam was washed out. It seems there is always less water in the Pecos than we need... I think the water quality is worse now-- not that the Pecos River was ever beautiful and clear. When my grandfather got here 110 years ago, they had a lot of water problems then. The prospect of fixing the saltcedar problem and making this area come back the way it was 100 years ago looks bleak for to me...I don't know if we can do that --Quotes from long-time residents of the Pecos River of Texas

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 results of a questionnaire distributed between European teachers. A research on the scientific imagery should have an opposite perspective to the one of a teacher at school; whereas the latter, the keeper of a knowledge, has the usual task of transferring and checking the knowledge in their students, a researcher has to record and describe their interior world relating to science – the information, but especially the images, the expectations, the emotions related to it.

If one of aims of science today is to respond to the real needs of society, it must find a new way to communicate with people and to be acquainted with their opinions and knowledge. Many science museums in Europe are adopting new ways to actively engage the public in the debate on topical scientific issues. The Museum of Science and Technology "Leonardo da Vinci" in Milan (partner of the SEDEC project) has thus experimented some formats for dialogue with teachers and with the public in general. Our experience shows that museums can be places where science and the public on the one hand and democracy on the other meet.

In the course of the last decade the European debate on the concept of citizenship has shown that a definition of this concept in strictly legal and jurisprudence terms is reductive. Indeed a behavioral element is present, which goes beyond the defence and request for defence of rights and duties, but actually stresses the importance of acting within a community (or within several communities). A citizenship belonging to a given space/time context which, to be authentic, requires know-how and know-how-to-be that can be gained in different training opportunities (formal, informal etc.) with various active learning methodologies and through experience. The SEDEC project aims to investigate which teaching methodologies and activities specifically developed for the teaching of sciences can be applied in other learning contexts, in order to sustain actions for developing an active citizenship.

IUFM is a centre for the in-service training of teachers and the development of didactic research. IUFM contribution to the SEDEC project is essentially built on a reflexion on educational implications of the links between science and European citizenship. We are convinced that European citizenship may be developed in scientific activities in school, by the introduction of communication moments, where pupils have to express and defend their ideas, and also to understand and accept the others’ ones. We have implemented two activities using the results of the SEDEC survey on science perception, that make the pupils get a better view on scientific research, especially in the knowledge of two scientific “jobs”, astronomer and botanist. Our approach consists of allowing the children express their conceptions of these jobs, of organising a debate to clarify these ideas, and of confronting them with other pupils’ opinions in Europe, with the history of the involved science and with direct testimonies of scientists. The project should be pursued in allowing classes in Europe to communicate about a scientific problem and so, to live their European citizenship.

We have analyzed the popularization activities undertaken by ten thousand CNRS researchers by means of their annual reports for the years 2004, 2005 and 2006. This is the first time that such an extensive statistical study on science popularization practices is carried out. Our main findings are : - the majority of researchers is not involved in popularization (51% has not done any popularization over the three-year period, two thirds have been involved in no more than one popularization action). - popularization practices are extremely diverse, both at the individual level (we have identified three subpopulations that feature distinctive attitudes towards popularization), and at the level of scientific disciplines (researchers in Humanities are twice as active as the average), as well as in laboratories or geographical regions. - the number of actions reported in 2005 greatly increased compared to 2004 (+ 26%), while they slightly diminished in 2006.
