Medicalisation means first of all a science – medicine – going beyond its boundaries: from the art of healing individuals, or systematically classifying useful information to treat diseases affecting individuals, it gradually turns into a pervasive development of knowledge and practices that, from the 18th century onward, are applied to collective issues, which traditionally are not regarded as medical issues, thus moving toward large-scale protection of the social body health. The physical wellbeing of people, as well as the protection and improvement of their health condition, become one of the main objectives of the political power, which aims not only at dealing with social marginalisation and poverty to make them productive, but also at “planning society as sphere of physical wellbeing, optimal health and longevity”.

The people of Val di Susa (Italy) blocked the construction of the new high-speed railway line that should connect Turin with Lyons (France). This project is regarded as a strategic achievement for the economic development of the European Union, but local communities have a different concept of development and are asserting their rights through ad hoc experts’ reports and the production “from the bottom” of new specialised knowledge. We shall describe these events as a case study to put ecological democracy to the test of facts, also through a comparison with the experimental actions taken in some Southern countries of the world. From Europe to Brazil, the debate on health and environmental risks resulting from modernisation is upsetting democratic societies and urging new forms of participation in the decision-making process. There is a clash between different “concepts of the world”, in which communication strategies play a crucial role and from whose outcome the society in which we wish to live in will emerge.

“In a totally sane society, madness is the only freedom”, writes J.G. Ballard in his novel Running Wild. This is a dark and at first sight enigmatic statement, but it could be interpreted as a stunning synthesis of the relationship between health policies and the practices of freedom in modern history. A game that is not yet over and the results of which must therefore still be deciphered. What do we do when faced with policies that act only for our good, which preserve life, improve the conditions of health and safety? And besides, what does it mean if these policies are seen as a threat and our freedom seeks refuge in madness as the last stronghold of resistance? These are the questions Ballard asks in his story.

The scandal of the “biotechnology evangelist” erupted in Korea at the beginning of the new year: a commission from Seoul National University announced that it had proof that Dr Woo Suk Hwang, considered one of the world’s foremost experts on cloning by nucleus transfer, had manipulated the data concerning experiments in human cell cloning and the creation of eleven lines of stem cells from human embryos published in two different articles in the journal Science in 2004 and 2005.

In recent years, courses, events and incentive programs for scientific journalism and the divulgation of science have proliferated in Brazil. Part of this context is “Sunday is science day, history of a supplement from the post-war years”, a book published this year that is based on the Master’s degree research of Bernardo Esteves, a journalist specialized in science.

From 1 to 3 June 2006, the 5th STEP Meeting devoted to the “Popularisation of Science and Technology in the European Periphery” was held in the city of Mahon in the island of Minorca (Spain). STEP ("Science and Technology in the European Periphery" [http://www.cc.uoa.gr/step/]) was founded in Barcelona in 1999, and gathers around hundred historians of science from all over Europe with a special interest in the role of Science and Technology in countries that traditionally have not played a leading role in the advancement of science and technology. The main results of the 5th STEP meeting are presented in this paper.

One of the most common, and probably one of the crucial questions about science centers and interactive exhibitions is often phrased as “Ok, it’s fun, but do they learn anything?”. What follows is not an attempt to answer this question; we will just use it as a starting point for a discussion about the role of explainers in science centers. Explainers are usually very motivated people, possessing a genuine interest in science and technology and a scientific background they are eager to share. And they feel everyone else should be as enthusiastic about science as they are. This is a legitimate aspiration, of course, but how exactly does one try to achieve this goal? What is the explainer’s role? Quite often, the answer to the question “…but do they learn anything?” is: “Yes, if we teach them”. It is simple, straightforward, probably it works to some extent, and this is the reasoning that makes explainers become… well, explainers. And this should be avoided.

This study presents the results of a qualitative analysis based on 13 crime news articles from Italian newspapers, to show that the belief that mental disorder predisposes many of those suffering from it to behave violently has endured, though the 180 bill was passed 25 years ago. Although the question has already been addressed by social psychologists and psychiatrists, it has not been discussed in great detail by science communication. However, this considers crime articles in newspapers as very interesting examples of indirect communication on health issues, where common belief prevails. The articles analyzed were about two matricides dating back to 1972 and 2001 respectively. The analysis showed that the belief that people with mental illnesses are recognizable, antisocial, can behave violently and cannot recover, has endured over many years. Nevertheless, statements about people with mental disorders are more accurate and the idea that the risk of violence among released mental patients is predictable, has been set aside.

Techniquest was established in 1986, and in 1995 moved to its current premises at Cardiff Bay, South Wales. This was the first purpose-built science centre in the UK. It receives around 200,000 visitors every year to its exhibition, and to its programmes for schools and public audiences in the theatre, laboratory, discovery room and planetarium. The author joined the Techniquest project in 1985, became a staff member in 1990 and was the Chief Executive from 1997 until his retirement in 2004. Techniquest has three “out-stations” in Wales, and is responsible for the supply and maintenance of exhibits to the Look Out Discovery Centre in Bracknell, England. There is a Techniquest gallery at the Lisbon Pavilhão do Conhecimento - Ciência Viva, and a traveling exhibition, SciQuest, in South Africa which was also supplied by Techniquest. All these centres rely on the effective intervention of “Explainers” (at Techniquest we call them “Helpers”) to provide the best possible experience for visitors. At its most demanding, the tasks of an Explainer are varied and intensive, yet there may be times when the duties are mundane or even dull. When you rely on people to act as both hosts and housekeepers, to provide both support and stimulus, and to be both welcoming and watchful, you are asking a great deal. This article raises some of the issues concerned with the recruitment and retention of Explainers, their training and management, and the way in which their role is recognized and valued by the science centre as a whole.

Hiša Eksperimentov (The House of Experiments) is a very small science centre. We are situated in the centre of Ljubljana, the capital of Slovenia. The gross area of the centre is only 500 square meters and we meet around 25,000 visitors per year. We were opened for the public in the year 2000. In the Hiša Eksperimentov there are four full-time employees and around 10 persons working and paid by fees. There are specific institutions present in Slovenia so called Student services. They help students in finding paid job on daily basis. The state still encourages students to work by lowering the taxes for their job. There are around 25 students working as explainers in Hiša. Here are some facts about Slovenia. The population is around 2 million in the area of 20,256 square kilometers. There are 18 students per 1000 inhabitants. One can play a game with numbers – taking into account the area of Hiša and the population and area of Slovenia one can calculate that there is one person expected in an area of the size of 20 science centers. And there are even much fewer students present in the same area. But the number of visitors and students working in the center proves the density is larger. Therefore science centers do concentrate the population!
