The management of health risks related to scientific and technological innovations has been the focus of a heated debate for a few years now. In some cases, like the campaigns against the use of GMOs in agriculture, this debate has degenerated into a political and social dispute. Even risk analysis studies, which appeared in the 1970s in the fields of nuclear physics and engineering and were later developed by social sciences as well, have given completely different, and at times contradictory, interpretations that, in turn, have given rise to bitter controversies.

While the model for transmitting scientific information ­ a model that attributes the effects of a message on the public to the intent of the communicator mediated by text ­ is increasingly becoming an exclusive tool for communication novices, other alternative models are emerging and ­ most importantly ­ field research is being tested and examined.

The objective of this article is to present a panorama of the way in which journalistic coverage of science and technological themes is being carried out in Latin America, having as a case study seven newspapers of significant impact in the region. We analyzed all stories published by the science section during all the month of April 2004, in the following newspapers: La Nación, Argentina; El Mercurio, Chile; Mural, Mexico; El Comercio, Ecuador; O Globo, Folha de S. Paulo and Jornal do Commercio/Pernambuco, Brazil. A total of 482 texts were collected. The methodology joins quantitative and qualitative analysis. There are very few studies on science journalism in Latin America and even fewer that seek to explore a comparison among countries. We believe that studies such as ours can provide subsidies to stimulate the improvement of journalistic coverage of scientific and technological issues.

If we wish to attempt an initial analysis of the inquiry on the communication of science in Brazil, India and China that JCOM proposed in its three most recent issues, we should paraphrase Chinese science and science-fiction writer, Yan Wu: even though these three countries are emerging in the fields of economy and science, and are now part of a wide group of communicators, promoting numerous methods to divulge information, they don't yet have a sound theory on the communication of science to the public. This is not an insignificant problem because according to David Dickson, the director of SciDev.Net, democratic dialogue on scientific matters is crucial to modern societies. However, it is difficult to propose the highest possible level of democratic dialogue on science topics without having a sound theory about the communication of science. In addition, the difficulties increase in those countries where developing economies and systems of science are both new and impetuous, as is the case of Brazil, India and China.
