Scientific analysis of the biology of Maria Branyas Morera

Researchers from the Josep Carreras Leukaemia Research Institute conducted a comprehensive study on Maria Branyas Morera, who lived to the age of 117. Published in the journal Cell Reports Medicine, the research utilized a multiomics approach to analyze her blood, saliva, urine, and gut microbiome. The team used epigenetic clocks to calculate her biological age, finding that her tissues and blood were 10 to 30 years younger than her chronological age. A specific measurement based on ribosomal DNA indicated that her cells were approximately 23 years younger. Despite the average life expectancy for women in Catalonia being approximately 86 years, Branyas Morera avoided major age-related diseases such as cancer and dementia for most of her life. Doctors reported that she maintained clear mental function and good cardiovascular health until the final months of her life. The study highlights a biological paradox regarding her telomeres and the youthfulness of her gut microbiome. This case provides significant insights into the relationship between biological age and chronic disease.
