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

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.

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.

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.

This article introduces a study on the websites of several European public research institutions that aims at identifying the science communication model chosen and implemented online with the purpose of reaching different target publics. The analytical approach takes into account a number of indicators: from the institutional identity to the scientific features, from the interactive services to the internationalisation level, in order to evaluate whether the web provides an added value in the adopted communication model and in building a relation with the users. Lights and shades emerge from this study in which good practices side examples of a much weaker science communication approach, outlining a general context where a public research institution website has been still used as a presentation tool and its interactive opportunities have not been capitalised.

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.

The summer now gone has reported two episodes we would like to bring to the attention of the JCOM readers. Two minor pieces of news, unlikely to be in the limelight over the summer, when the media understandably focus on gossips and crime news. Even the experts – especially outside the Italian territory – would probably dismiss these events as minor, wouldn’t it be for the people involved. But let’s see the facts.

In a meta-analysis carried out in 2002, the two main associations of science centres and museums (ASTC, mainly US-centered, and ECSITE, mainly European) gathered all studies analysing the impact of science centres and museums on their local communities1. Four types of impact were identified: personal, social, political and economical. It was noticed that the vast majority of studies concentrated on the personal impact (that is, learning outcome, visitor satisfaction, etc.), while the latter three were largely neglected. The very fact of pointing this out, and many recent experiences - some of which are included in this commentary - show that there is now a shift of attention.

Since the first pioneering balloon flight undertaken in France in 1783, aerial ascents became an ordinary show for the citizens of the great European cities until the end of the XIX century. Scientists welcomed balloons as an extraordinary device to explore the aerial ocean and find answers to their questions. At the same time, due to the theatricality of ballooning, sky became a unique stage where science could make an exhibition of itself. Namely, ballooning was not only a scientific device, but a way to communicate science as well. Starting from studies concerning the public facet of aerial ascents and from the reports of the aeronauts themselves, this essay explores the importance of balloon flights in growing the public sphere of science. Also, the reasons that led scientists to exploit “the show of science aloft” (earning funds, public support, dissemination of scientific culture…) will be presented and discussed.

This paper addresses the role of museums in education in science and technology through the discussion of a specific project entitled EST “Educate in Science and Technology”. The Project puts together methodologies and activities through which museums can be used as resources for long-term project work. In-service training for teachers, work in class with learning kits or with materials brought in by a Science Van, and visits to the museum are planned and developed jointly by museum experts and teachers. The Project proposes a teaching and learning model which sees the museum experience as central and integral part of a teaching and learning process with more effective outcomes. The analysis of the Project activities and methodologies is based on the work carried out at the National Museum of Science and Technology Leonardo da Vinci, which perceives the learner (the visitor) at the heart of its educational methodologies and provision.
