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.
