Braga Science Film Fest is an international science short film festival, online and totally free. The festival is focused on promoting science communication through cinema, by nurturing the dialogue between scientific ideas and concepts and audiovisual narratives with creative content, accessible to different audiences. Apart from the short films in competition, the festival includes non-competitive sessions with some of the best films that have been screened by partner festivals, and a series of workshops and lectures that offer participants tools to understand and explore the potential of audiovisual in science. The 2023 edition of the festival is dedicated to ‘Symbiosis’ between science and cinema. How does the interaction between these two different organisms work and how do they mutually benefit from this relationship? That’s what we’re going to find out.
