On 18 May, as part of the International Museum Day programme, the Casa Reynaldo dos Santos - Irene Quilhó dos Santos opens the exhibition Creating Bridges, Leading Paths - 60 Years of Maria de Sousa's Discovery and launches the Seeing the Unseen Lecture Series. The exhibition celebrates the 60th anniversary of a scientific discovery by Maria de Sousa, highlighting her pioneering contribution to Immunology and to scientific thought in Portugal. Organised around key moments of her life and career, the exhibition presents documents, testimonies and objects that allow us to understand both the impact of her scientific work and her intervention in the debate on the role of science in society. By highlighting the connection between research, culture and citizenship, the exhibition proposes a comprehensive reading of Maria de Sousa's legacy. As part of the exhibition Creating Bridges, Leading Paths - 60 Years of Maria de Sousa's Discovery, the Seeing the Unseen lecture series takes place, proposing a meeting between science, memory and social commitment, evoking the work and legacy of the scientist Maria de Sousa, around 60 years after her pioneering discovery. Recognised for her fundamental contribution to immunology, Maria de Sousa opened innovative paths in understanding how the immune system works, revealing mechanisms previously invisible to the scientific eye. Throughout this series, various scientists from different fields are invited to revisit her work, not only in its technical and academic dimension, but also in its deep connection to society. The lectures combine scientific knowledge with ethical and civic reflection, highlighting the role of science as a tool for social transformation and for building a more informed and just world. Seeing the Unseen is thus a space for interdisciplinary dialogue that celebrates curiosity, rigour and commitment, values that marked the life and career of Maria de Sousa, and which continue to inspire new generations of researchers and citizens. 18 May | 6 p.m. Two Scientists, Iron and Macrophages: a zebrafish tale, lecture by scientist Rita Fior, principal investigator at the Champalimaud Foundation. 27 May | 6 p.m. Moments then, Eternities now: the legacy of Maria de Sousa, a personal vision, lecture by Cláudio M.
