This podcast tells the incredible life story of Mario Capecchi, a world-renowned geneticist and Nobel Prize winner. His journey began amidst the turmoil of World War II, where he experienced unimaginable hardship as a child. Abandoned and left to fend for himself on the streets of war-torn Italy, Capecchi endured hunger, illness, and witnessed traumatic events that left deep scars.

Despite these challenges, his spirit of resilience and survival shone through. After the war, he was reunited with his mother and immigrated to the United States, finding a supportive environment with his uncle, a prominent physicist. This newfound stability, combined with his innate curiosity and determination, fostered his passion for science.

Capecchi's scientific pursuits led him to Harvard University, where he worked in the laboratory of James Watson, co-discoverer of DNA. Inspired by Watson's mentorship, Capecchi was drawn to tackling fundamental questions in genetics. Eventually, he established his own laboratory at the University of Utah, seeking a less competitive environment to focus on his research.

There, Capecchi embarked on a risky and ambitious project: developing a technique for targeted gene modification in mice. Despite initial skepticism from funding agencies, he persevered, driven by a vision of the potential impact. His groundbreaking work led to the creation of "knockout mice," a revolutionary tool for understanding gene function and developing new disease therapies.

In recognition of his transformative contributions to science, Capecchi was awarded the Nobel Prize in Physiology or Medicine in 2007. His research has had profound implications for medicine, leading to new treatments for a wide range of diseases, deepening our understanding of gene function, and paving the way for personalized medicine.

However, the story doesn't end there. Capecchi's Nobel Prize win unexpectedly led to the reunion with a long-lost half-sister, Marlene Bonelli, bringing a poignant closure to a chapter marked by wartime separation and loss.
