In November 2018, the world heard the news: at a conference in Hong Kong, Dr. He Jiankui announced that he created two children with edited genes—twins named Lulu and Nana. Scientists around the world are trying to catch up with China in genetic research. Gene editing can drive an innovative economy, but it may also worsen economic and racial inequality. At stake are fundamental questions of science, healthcare, and social justice: who will get access to gene-editing technology? Eben Kirksey introduces you to the leading scientists, popularizers, and entrepreneurs who have brought cutting-edge genetic engineering technologies—like CRISPR—into hospitals across your cities. This book is not written from an “ivory tower.” The author discusses pressing issues with doctors, people living with chronic illness, and activists who have a different view of humanity’s genetically modified future.
