Walter Isaacson, author of best-selling biographies of Steve Jobs, Albert Einstein, Leonardo da Vinci and many others, tells how Jennifer Daudna and other scientists began a revolutionary process that will allow us to fight disease even more effectively, defeat viruses and raise healthier offspring. The genome editing tool developed by Daudna and her colleagues, CRISPR, is already being applied in the treatment of sickle cell disease, cancer and blindness. In 2020, Daudna and her teams began to study how CRISPR can detect and destroy coronavirus. In the same year, Daudna and her co-author Emmanuel Charpentier received the Nobel Prize in Chemistry.
