The Radio is an instrument of communication that has percolated to all the strata of the diverse Indian society. Its position has been consolidated through history as a regular companion and a source of information and entertainment. Its affordability, accessibility and non-reliance on costly resources have ensured its presence in almost all the households. It has become indispensable from kitchens, family rooms and even workspaces. It is one of the few or rather the only medium of communication after the print media wherein information dissemination still is primary and entertainment a secondary requirement, especially the rural areas.

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".

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 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 on 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 article.

The Regional Park of the Po River Delta1 was set up in 1988 (it belongs to a Consortium of Public Bodies). It extends over 54,000 hectares of land and stretches across 45 km of the Italian Eastern coastline (45 km of the more than 90 km that go between the provinces of Ferrara and Ravenna)2 and is one of the largest and most significant natural parks in Italy.

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.

In the name of God is the heading chosen by some researchers from a Middle Eastern country for their posters in an international conference on chemistry which has recently been held in Paris. This powerful message preceded the results of the researchers' work on the morphology, molecular structure, as well as the physical, chemical and mechanical properties of advanced polymeric materials. It was an unexpected statement, an unusual message, though certainly not an unprecedented one. It had nonetheless a striking effect in the context of a scientific conference attended by thousands of people from various ethnic and religious backgrounds.

In a beautiful Barcelona, bathed in sun, the 8th PCST Congress was celebrated at the beginning of June.1 Besides the magnificent location of this year, there are several other reasons to commemorate the event. The first reason is that the community of professionals and scholars interested in Public Communication of Science and Technology (science journalists and writers, scientists, sociologists, teachers, historians, science museum curators, etc.) is growing quickly.

I would like to start with a brief news item in the August 1999 issue of National Geographic which gives some food for thought: "With 5,000 climbing routes, such as Double Dogleg and Walk on the Wild Side, California's Joshua Tree National Park attracts about 140,000 enthusiasts a year to test their skill on granite boulders. But some visitors view their metal bolts as defacements hammered into rocks.
