The scientific institution in Brazil is marching to a good rhythm. Despite problems in funding (and in the very irregular distribution of such funds), universities and private research centers changed and grew over the last few years. In 1999, Brazil (whose external debt is over 50% of GDP), invested 0.87% of GDP in Research & Development: a percentage comparable to that of several Mediterranean countries.

Internal scientific communication and public communication of science and technology are growing in Brazil at a good pace, along with scientific productivity. In this Focus we will try to analyze the debate on standard or alternative models of communication of science that can be seen in the practice of science journalism and popular science in Brazil.

The question was raised in the 4th November copy of The New York Times when it entitled the editorial of Garry Wills (political and cultural historian), regarding the re-election of George W. Bush, "The Day the Enlightenment Went Out". Wills' theory, with which the directors of the newspaper palpably concur, is that Bush was re-elected because "many more Americans believe in the Virgin Birth than in Darwin's theory of evolution".

The international symposium Science on air: the role of radio in science communication was held in Trieste on 1 and 2 October, 2004. To our knowledge, it is the first conference ever specifically held on science in radio, and it is certainly the first time science radio journalists, researchers, and media experts from 16 different countries met to discuss their journalistic practice and the role of radio in science communication. The main results are presented in this section.

The objective of the present paper is an attempt to measure the public understanding of science in the area of health and hygiene and test the efficacy of "cultural distance model". A pre-tested open-ended questionnaire was used for administering cross-sectional surveys at a religio-cultural festival in India. 3484 individuals were interviewed and responses were coded and entered to construct computer database. The data was used for determining the cultural distance of five scientific concepts from the quotidian life of the target population. In developing countries, the formal system of modern education operates as a strong determinant in shaping cultural structures of thoughts prevalent among the citizens. There exists a cultural distance between the scientific structure of configuring natural occurrences and peoples' complexity of thoughts. The distance varies significantly across the concepts that were subjected to the inspection and is a function of the nature of scientific information.

Natural parks are a place where science communicates with the public, involving dimensions ranging from the knowledge of living species to the relationship between man and nature, the environmental policy decisions and the anthropic impact assessments. Natural parks are therefore an important arena for scientific communication where the "shared participation" tools play a fundamental role. To this end, we report a few international experiences that illustrate the role of the interest holders and the importance of coordination of the parties involved in the management of parks.

Never have there been so much science and so much technology on so many sides as now. The expansion of scientific information in the social sphere is frankly impressive. In newspapers and movies, on television and radio, scientific ideas circulate freely every day of the week. Science is in cell phones, shampoo, compact discs, Olympic athletes' clothing, food, perfumes, and in so many places that trying to enumerate them would be insane. After all, why should it be particularly strange to speak of science and technology if scientific thought finally molds our deepest fibers? Today's society, developed or not, lives immersed in a scientific and technological culture which guides the course of the most fundamental events. Even though, of course, the common sense obliges us to admit that the majority of us are not fully conscious of its reach and consequences. Perhaps this helps to understand why we still feel a certain shame when, in a social gathering, we comment that our profession consists of spreading science or analyzing the ways in which it circulates and its repercussions in the public opinion. It may be that we live with the fear that someone will look at us strangely and with disbelief and ask us to explain what scientific communication or the social studies of science consist of or, worse yet, that we find ourselves in the embarrassing situation of rehearsing an answer to justify the importance of thinking about science in daily life.

The eighth convention of the PCST (Public Communication of Science and Technology) network, which took place in Barcelona this June, emphasised an increasing richness in reflection and practice with regard to several themes to do with science communication. This growing variety mirrors the different approaches gradually coming about in different cultural and geographical contexts. In particular, the Focus of this issue of JCOM concentrates on a presentation of the models of interpretation of science communication referring to the Mediterranean and South American cultural area.

In The Areopagitica, his most important work of prose, John Milton mentions Galileo as the illustrious martyr who fought for the freedom of thought. The name of the great scientist is repeated several times in the English poet's epic masterpiece: Paradise Lost. In three different passages of the poem, Milton in fact celebrates the "Tuscan Artist" and his crucial achievements in astronomy. Nevertheless, in a subsequent passage, the poet addresses the Copernican issue without openly defending the heliocentric theory confirmed by Galileo's discoveries. In fact, he neither embraces the Copernican system nor the Ptolemaic one, but instead compares them, following a dialectic method where one cannot fail to notice an echo of Galileo's Dialogue Concerning the two Chief World Systems. Milton's literary work presents images of astronomy at that time, thus offering a valuable historical example of scientific communication through art.
