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.

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.

In 2007 the Life Long Learning Programme (previously Socrates) of the European Commission has started. The programme offers to teachers, educators and policy-makers of the education sector the opportunity to be funded for participating at various training courses organized in all EU countries by international networks and projects. The SEDEC course will be included in that list in 2008. The article shortly present how to ask for a grant.

To design teaching materials starting from the subject matter in Science field, from the contents of textbooks or by studying the syllabuses are regular practices within schools. The SEDEC project proposes concrete and innovative modalities of conceiving teaching materials starting from teachers perception of science and by talking with them about their ideas and needs regarding teaching Science. A deep discussion of the relationships between science education and European citizenship has been another important ingredient of this new process of didactic design.

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 analysis of more then 1000 drawings realized by 9 and 14 years old pupils and representing "a scientist". Form the drawings emerge stereotypes, fears, desires, expectations and more, a whole imaginery that has to be taken in account for an effective educative adn communicative action.

Two concepts seemingly distant from each other, scientific education and European citizenship, have been the basis for "SEDEC - Science Education for the Development of European Citizenship", a European project funded by the European Commission in the framework of the Socrates/Comenius programme, aiming at producing training material addressed to European teachers. Started in autumn 2005, the project will end in 2008 with an in-service training course for European teachers and educators.

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.
