"The bestselling author of Leonardo da Vinci and Steve Jobs returns with a gripping account of how the pioneering scientist Jennifer Doudna, along with her colleagues and rivals, launched a revolution that will allow us to cure diseases, fend off viruses, and enhance our children"--
Driven by a passion to understand how nature works and to turn discoveries into inventions, Doudna 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. Isaacson explores the development of CRISPR and the race to create vaccines for coronavirus will hasten our transition to the next great innovation revolution. -- adapted from jacket

Nothing, really. It's a bit flat. Sorry.

RNA is the focus of this book, which is about both Nobel prize winner Jennifer Doudna and the rapid development of biotechnology to alter genes using CRISPR. It unfolds in three parts with Doudna's RNA research as the common thread: first Doudna's early career as a scientist; then a review of the moral issues surrounding gene editing; and finally the future use of RNA-based technologies to destroy viruses in the body without engaging the immune system. There are excellent descriptions of the current different Covid-19 vaccine types and how they work. Isaacson has a gift for making complex science easy to understand and exciting. He captures the camaraderie and competition between labs and the personalities of the researchers, which lend drama to the story.

The 2020 Nobel Prize in Chemistry was jointly awarded to Emmanuelle Charpentier and Jennifer Doudna for their work on the development of CRISPR Cas9, a method for genome editing.

This book tells the story of gene editing and in particular the discovery of a gene editing tool CRISPR Cas9. The book’s main character is Jennifer Doudna.

The author tracks the story of Doudna’s journey working on RNA and her collaborative and competitive work with other scientists, including Charpentier, which eventually lead to CRISPR and various discoveries related to it.

I was a little hesitant to read this book as I thought the subject will be quite narrow and specific, being essentially a biography of a basic scientist. However I truly enjoyed how the author opened my mind to this fascinating field of study which has particularly special applications at the time of COVID.

It is very thought provoking as well. Gene editing has applications to produce therapies for genetic and viral diseases. However, if not guided by the highest level of scientific ethics and regulations it could be maliciously utilized to tailor the production of embryos with particular genetic traits (the author tells a story of one case from China).

Walter Isaason, is also the author of a very interesting book on Leonardo da Vinci.

The book starts out strong, presenting Dr. Jennifer Doudna as growing up in Hilo HI and being given the Double Helix book by her dad, that inspired her career path. At some point the author’s admiration for Doudna becomes sycophantic, as he can no longer look at her objectively.

For example, Doudna gets into a patent battle with Dr. Zhang, a rival scientist, and Isaacson advocates her position, basically denigrating Zhang’s accomplishment. He comes close to calling him a cheat and unethical. He also goes along with Doudna’s claim that Zhang’s findings were obvious for her work and therefore not deserving of a patent. But the courts have disagreed and Isaacson much later in the book admits that Zhang’s contribution of applying CRISPR to eukaryotic cells was a major accomplishment.

Then the book’s trajectory gets changed for the last third due to COVID. The author desperately tries to present Doudna as a major figure to find a test and vaccine for COVID, but this just reflects his sycophancy. She participated in developing a test that was used locally and had no discernible input on the vaccine.

Despite having described scores of scientists no mention is made of Dr. Kariko, whose work in RNA was fundamental for the development of the Pfizer and Moderna vaccines. This is crazy when you consider that the author has included vignettes of dozens of scientists along the way.

Isaacson keeps going back describing a rogue guy who wants to sell CRISPR supplies for DIY hobbyists, yet spends a few sentences on Dr. Liu, whose base replacement technique may well supplant CRISPR.

Here is a good writer who simply got too close to a personality and lost sight of the scope of the science that has been the sum accomplishment of many talented scientists.

I give the first third of the book four or five stars. It's a fascinating subject and Jennifer Doudna's life and career is interesting and compelling. What I didn't care for was the endless series of short biographies of other scientists who were peripherally involved; I would have much preferred a more targeted account and I ended up skimming over most of the last half of the book. A pity, since Walter Isaacson is a talented writer and I loved his biographies of Einstein and Steve Jobs, both of which were more in-depth.

A good story about the collaboration and competition in biotech science. The CRISPR technique enables editing of our DNA. But as the book points out there are relatively few diseases that can be eliminated by changing or removing one specific part of the defective gene. Genetic traits such as height, intelligence, hair & eye color, etc. that people may want to select for their children are not as simple as editing a specific section on one gene in our DNA. But that won't stop people from trying. Isaacson discusses this issue toward the end of the book. Genetic engineering, patents, and profiting from biotech are also issues that society will have to face.

“At the end of the day, the discoveries are what endure. We are just passing on this planet for a short time. We do our job, and then we leave and others pick up the work.”

I am a huge Walter Isaacson fan since I've read his biographies of Steve Jobs and Leonardo daVinci which I thoroughly enjoyed. I was, however, sceptical about his ability to write about a character who was a science expert. Isaacson surprised me. He not only did justice to the subjects of Biotechnology, and Biochemistry but explained the details such that a layperson like me could understand the nuances of RNA and the CRISPR technology. The book was particularly interesting because of the personalities involved like Nobel Prize winners Jennifer Doudna and Emanuelle Charpentier and the rivalry with Feng Zhang. All in all an eminently readable book.
