We live in a unique moment in the history of Brazil in which the field of knowledge is under attack. The podcast “Cientistas na linha de frente” (Scientists on the Front Line) tells the story of science heroes who today have not only their studies and funding threatened but, in some cases, their safety. The report travels around Brazil searching for stories and transports the listener into the investigation. Each episode addresses a different universe and brings not only the human side of the researchers who work on the topic and the pressure they face daily – and their passion and commitment to science – but also details the scientific work and advances they carry out. The series allows a dive into the reality of professionals who work with statistical institutes, reproductive rights, pesticides, environmental protection, and the demarcation of indigenous lands.
