In the last few years, embryonic stem cell research has been widely debated in Brazil and a “star” in the national media. Because of the notoriety of the issue, the media have sometimes been criticized for oversimplification, exaggeration and distortion. In this context, we analyzed the media during an important time: in 2008, the Federal Supreme Court held historical hearings to decide whether Brazilian scientists could continue using embryonic stem cells. First, we focused on letters sent by readers to one of the most popular newspapers, O Globo. Second, we analyzed the Brazilian news coverage of embryonic stem cells during a crucial week in the public debate. At the end of May 2008, under pressure from Brazilian media and society, the Ministers of the Supreme Court approved research using embryonic stem cells.
