Maria Branyas Morera, a Spanish supercentenarian, reached the extraordinary age of 117 years and 168 days before she passed away last year. Although she was born in the United States, she moved to Catalonia in 1915 and spent the rest of her life there.

Throughout her lifetime, Maria lived through two world wars, saw 21 U.S. presidents serve in office, and witnessed countless technological and social changes that shaped the modern world. Because of her remarkable lifespan, she drew attention from researchers around the globe.

Before she died, Maria asked that scientists study her DNA, hoping that her case might help uncover clues about living longer. Researchers from the University of Barcelona and the Josep Carreras Leukaemia Research Institute conducted the study, gathering biological samples to analyze her genetics and the condition of her cells.

Dr. Manel Esteller, who led the research, noted that Maria seemed to break the typical link between aging and illness. Speaking to The Times, he explained that her case showed it may be possible to distinguish growing older from becoming sick. He also mentioned that while her genetics likely played a significant role, future medical advances might eventually replicate some of those effects through new treatments.
