Several researchers operating in the sociological field have recently theorised that genetics and biotechnologies are at the core of the public perception of science. The present study aims at verifying empirically whether or not this is mirrored in Italian mass media, as well as at analysing the topics most frequently present in Italian newspapers and the economic and editorial reasons behind the results of editorial choices. Besides, it provides statistics about the major Italian newspapers published in the last third of 2002. This period has been chosen because some important news was published in December: it consequently offered the chance to carry out a long-term analysis as well as a study of the most important differences - in content and editorial lay-out - between scientific articles which are published in the appropriate sections inside the newspaper and those which make the front page. Ours are going to be purely quantitative considerations; but, from the point of view of the content, the data are sufficient to identify various narrative currents. These currents could be the object of further research on the frames used to contextualize the news and the reasons (anthropological, socio-cultural and editorial) for the way they are used by editorial staffs.

Historical background The BBC Radio Science Unit has its roots in two radio networks, going back more than 40 years. In the late 1950s, BBC External Services (now World Service), appointed a science correspondent and began a weekly science magazine programme. Initially called `Science and Industry', it changed its name in about 1964 to `Science in Action'. It is still running today, after more than 2000 editions, probably making it the longest running science show on radio.

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.

Contemporary radio is under-studied by academic researchers, while on the contrary it expresses great exigencies of knowledge. Media studies examined deeply radio when it was the mainstream medium, i.e. in the Thirties, especially in the US also for marketing needs of a largely commercial broadcasting system.

What makes a science story? Behind the scene there are many choices: what, how and when to broadcast. Decisions are made according to the general criteria of news values to which we add two groups: personal and emerging criteria. General criteria of choices are news values for the science stories. According to Tonner, stories containing human interest are important in everyday life, report less complicate discoveries and science as a part of the broader subject comes to the media easily.

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.

A word of warning for scientists: don't appear on talk-shows. Not only would you probably run into a magician, you might even be mistaken for one, which is much worse. And do not ask the press, the radio and television to put their magical mentality aside: the media are condemned to it. It is not just a matter of what the audience wants. It is the cause-effect relations the media constantly have to establish that have per se something "magic".
