About the post: Conceptual transformations and emerging thematic agendas in the anthropology of science and technology become clearly visible in STS conferences. Paying particular attention to conferences that take place in the global South has the potential to open up an understanding of post-colonial scientific endeavors within our own field of expertise. A case in point was the 8th edition of the biannual meeting of the Brazilian Network of Anthropology of Science and Technology, known as ReACT (Reunião de Antropologia da Ciência e da Tecnologia), which took place on November 22-26, 2021.
