The Code Breaker


Book Description

A Best Book of 2021 by Bloomberg BusinessWeek, Time, and The Washington Post The bestselling author of Leonardo da Vinci and Steve Jobs returns with a “compelling” (The Washington Post) account of how Nobel Prize winner Jennifer Doudna and her colleagues launched a revolution that will allow us to cure diseases, fend off viruses, and have healthier babies. When Jennifer Doudna was in sixth grade, she came home one day to find that her dad had left a paperback titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved. When she read it on a rainy Saturday, she discovered she was right, in a way. As she sped through the pages, she became enthralled by the intense drama behind the competition to discover the code of life. Even though her high school counselor told her girls didn’t become scientists, she decided she would. Driven by a passion to understand how nature works and to turn discoveries into inventions, she would help to make what the book’s author, James Watson, told her was the most important biological advance since his codiscovery of the structure of DNA. She and her collaborators turned a curiosity of nature into an invention that will transform the human race: an easy-to-use tool that can edit DNA. Known as CRISPR, it opened a brave new world of medical miracles and moral questions. The development of CRISPR and the race to create vaccines for coronavirus will hasten our transition to the next great innovation revolution. The past half-century has been a digital age, based on the microchip, computer, and internet. Now we are entering a life-science revolution. Children who study digital coding will be joined by those who study genetic code. Should we use our new evolution-hacking powers to make us less susceptible to viruses? What a wonderful boon that would be! And what about preventing depression? Hmmm…Should we allow parents, if they can afford it, to enhance the height or muscles or IQ of their kids? After helping to discover CRISPR, Doudna became a leader in wrestling with these moral issues and, with her collaborator Emmanuelle Charpentier, won the Nobel Prize in 2020. Her story is an “enthralling detective story” (Oprah Daily) that involves the most profound wonders of nature, from the origins of life to the future of our species.




The Code Breaker -- Young Readers Edition


Book Description

Walter Isaacson’s #1 New York Times bestselling history of our third scientific revolution: CRISPR, gene editing, and the quest to understand the code of life itself, is now adapted for young readers! When Jennifer Doudna was a sixth grader in Hilo, Hawaii, she came home from school one afternoon and found a book on her bed. It was The Double Helix, James Watson’s account of how he and Francis Crick had discovered the structure of DNA, the spiral-staircase molecule that carries the genetic instruction code for all forms of life. This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry: figuring out the structure of RNA, a closely related molecule that enables the genetic instructions coded in DNA to express themselves. Doudna became an expert in determining the shapes and structures of these RNA molecules—an expertise that led her to develop a revolutionary new technique that could edit human genes. Today gene-editing technologies such as CRISPR are already being used to eliminate simple genetic defects that cause disorders such as Tay-Sachs and sickle cell anemia. For now, however, Jennifer and her team are being deployed against our most immediate threat—the coronavirus—and you have just been given a front row seat to that race.

This will be a wonderful book club read!"--MADELINE MARTIN, New York Times bestselling author of The Last Bookshop in London In 1942, an impulsive promise to her brother before he goes off to the European front puts Avis Montgomery in the unlikely position of head librarian in small-town Maine.

The women she convinces to attend the first meeting couldn't be more different--a wealthy spinster determined to aid the war effort, an exhausted mother looking for a fresh start, and a determined young war worker. At first, the struggles of the home front are all the club members have in common, but over time, the books they choose become more than an escape from the hardships of life and the fear of the U-boat battles that rage just past their shores. As the women face personal challenges and band together in the face of danger, they find they have more in common than they think. But when their growing friendships are tested by secrets of the past and present, they must decide whether depending on each other is worth the cost.
