The knowledge society is a new social species that, despite many uncertainties and some (old and new) ambiguities, is emerging on the horizon of the 21st century. Placed at the convergence of two long-term processes (society of individuals and knowledge society), it is characterised by the social-economic process of knowledge circulation, which can be divided into four fundamental phases (generation, institutionalisation, spreading and socialisation). The current situation also sees the traditional (modern) structure of knowledge being outdated by the convergence of nanotechnologies, biotechnologies, information technologies and neuro-cognitive technologies (NBIC). In the background, the need arises to cross the cultural frontier of modernity.

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

After serving the community for seven years, the Science Museum of Castilla-La Mancha (MCCM) has decided to renew itself. In this context, a survey of the needs and expectations of the people to which the museum is dedicated plays a major role for the changes planned to prove successful. Teachers are among the main users of the museum, staying at the core of all teaching-learning processes, and play a role as mediators between science and students. This paper analyses the judgements made by teachers about various types of events and teaching resources which are normally provided by science museums and, more specifically, the Science Museum of Castilla-La Mancha. Against that backdrop, science (our content), education (our objective) and the democratic participation of teachers will show a clear route to follow if one wants to achieve quality for our institution and its future events.

Sometimes scientists live real dramas or undergo social and psychological conflicts which have a positive or negative influence on the development and recognition of their research, discoveries and inventions in society, including the way they are recorded in history. This being so, the question is: to what extent can science be communicated to the public at large by the use of scientists' biographies as a motivational strategy? The controversy arises from the fact that usual (classical) science has traditionally argued for the separation (or de-linking) of the research (the object) from the researcher (the subject).Thus, if the above-mentioned motivational strategy is used in scientific communication, it could break a dominant methodological trend and consequently lead to a questioning of the myth of axiological neutrality in science. The communication of science by means of scientists' biographies could be useful for reaching a specific public, more directed towards emotional aspects, thereby awakening its interest in science, even amid cultural differences and in environments where interest in science and its utility is lacking. It could also reveal human aspects of the everyday life of scientists, bringing them closer to the public at large, which would contribute to the dissemination of science and knowledge.

Probably among the first to deal with it, nearly sixty years ago, Norbert Wiener, the founding father of cybernetics (The human use of human beings. Cybernetics and Society, Houghton Mifflin Company, London, 1950), prefigured its opportunities, as well as its limitations. Today, it is a quite common belief. We have entered (are entering) a new, great era in the history of human society: the age of information and knowledge.

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.

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.

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.

This paper relates to a special case of science-society mediation set up during the Science et Cité festival 2005. This national event took place in about twenty cities in Switzerland to promote a closer cooperation between science and society via art (theatre, music, dance, exhibitions, cinema, etc.), in order to reach the population at large. Results on the profile of the public, the role played by the cultural institutions involved, the motives of the visitors and the role of art in the science-society dialogue show that the goals aimed at by the festival's organisers were only partially reached. Moreover, the analyses shed light on the complex relation between art, science and society in public understanding of science activities.

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.
