Jennifer Doudna’s work on CRISPR gene editing is revolutionizing science and medicine, but also poses ethical and societal challenges.

Walter Isaacson: The Code Breaker


"The Code Breaker" by Walter Isaacson is a biography of Jennifer Doudna, a biochemist who co-invented the CRISPR gene-editing technology, and a exploration of the ethical, societal, and scientific implications of gene editing. The book details Doudna's journey from a curious child to a world-renowned scientist, and how she and her colleagues discovered the CRISPR-Cas9 system that allows for precise gene editing. Isaacson also delves into the various ways that CRISPR is being used and the debates surrounding its potential uses, including curing genetic diseases, creating genetically modified organisms, and even enhancing human abilities.

5 funny quotes

  1. "As a teenager, she was an unlikely nerd. She was too busy being a cheerleader and dreaming of becoming a movie star. Or maybe a surgeon."
  2. "Though a fan of most things English, she was not a fan of the British approach to breakfast, which involves something called "black pudding."
  3. "When you're in a tight spot, it helps to have a friend who has been to war, battled cancer, and raised teenage boys."
  4. "We live in a world of wicked problems. And if this book has any message, it's that we need more code breakers."
  5. "When I first visited Jennifer's lab, I was delighted to see a stack of books that included those by some of my favorite writers, such as David Foster Wallace and Joseph Heller. It was reassuring to find that the world of scientific research is not populated only by tech nerds."
