Doctors investigate DNA of 117-year-old woman to find one food that can unlock longer lives

Many of us dream of living forever — and science is making huge strides in that direction.

Now, the DNA of an American-Spanish woman is giving us even more clues.

Made a remarkable request

Maria Branyas Morera was born in the United States on March 4, 1907 — seven years before the outbreak of World War One. The Spanish-American supercentenarian lived an extraordinary 117 years, passing away in 2024 after a life that spanned more than a century of history.

During her lifetime, she witnessed two world wars, 21 U.S. presidents, and countless technological innovations that completely transformed the way people lived. Although born in San Francisco, Maria moved with her family to Spain in 1915 to settle in Catalonia.

Tragically, her father died from pulmonary tuberculosis toward the end of the journey, but Maria went on to spend the rest of her remarkable life in her adopted homeland.

Before she died, she made a remarkable request: she asked doctors to study her DNA to understand what made her the world’s oldest living person, hoping her insights could help others live longer.

This request prompted a team of Spanish scientists, including researchers from the University of Barcelona and the Josep Carreras Leukaemia Research Institute, to examine her biological profile. They started collected tissue samples and analyzed her cells and genetics.
