This article discusses the Brazilian science based on a new resource for scientometrics called Nature Index, as well as the SJR. The 2012–2015 change in the main metric of Nature Index showed an increase of 18.9% for Brazil and currently is ranked 24th globally. From 1996 to 2015 (SJR) Brazilian science has produced more than 600 thousand citable papers, obtained more than 5 million citations, having over 400 papers with at least 400 citations and is responsible by half of Latin America publication output. Despite such numbers, there are flows in its internationalization. Much of the Brazilian science is produced by graduate students and professors gazetted, since the profession of scientist in Brazil is not a recognized position by the Ministry of Labor and Employment.
