The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

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.

After being uneasy allies in World War II, the 1950s saw the United States and the Soviet Union entering the Cold War, a thirty-year conflict in which the adversaries never went into physical battle with each other but fought many proxy wars in other nations. This gripping and fast-paced book traces the Cold War through the lens of spying and code breaking by showing how advances in computer technology and mathematics kept the technology race every bit as nerve-racking as the arms race that characterized the conflict.
"This innovative collection of analyses builds a badly needed bridge between solid visual communication research about legacy media and emerging scholarship about Web-based media."---Julianne Newton, Professor of Visual Communication in the School of Journalism and Communication at the University of Oregon; Co-author of Visual Communication: Integrating Media, Art, and Science --
An internationally acclaimed economist, Bina Agarwal is known for her path-breaking writings on agriculture, property rights, and the environment. Her three-volume compendium brings together a selection of her essays, written over three decades. Combining diverse disciplines, methodologies, and cross-country comparisons, the essays challenge standard economic analyses and assumptions from a gender perspective. They provide original insights on a wide range of theoretical, empirical, and policy issues of continuing importance in contemporary debates. The first volume spans varied dimensions of the author’s writings on agrarian change, from 1981 to the present. It identifies gender inequalities in the impact of agricultural modernisation and technical change across Asia and Africa; the links between women, poverty, and economic growth processes; and data biases in measuring women’s work. It traces the gendered costs of droughts and famine, and challenges top-down methods of innovation diffusion. Focusing on the key role of women farmers in food security, it also offers innovative solutions, including public land banks and group farming. The second volume focuses on the author’s paradigm-shifting work on women’s property status in South Asia. Challenging conventional approaches to women’s empowerment, it demonstrates how promoting access to property, especially land, is key to enhancing women’s economic and social well-being and deterring domestic violence. It details gender inequalities in inheritance laws, public policies, and land struggles, and presents the bargaining framework for understanding and finding ways of overcoming these inequalities, both within families and in markets, communities, and vis-à-vis the state. This third volume traces the relationship between gender and environmental change. Critiquing ecofeminist assumptions, it presents an alternative theoretical framework. It also examines the causes of women’s absence as well as the impact of their presence in environmental collective action. Based on innovative fieldwork on community institutions for forest governance, the author demonstrates how a critical mass of women can significantly improve conservation outcomes. In conclusion, she reflects on which features of feminist scholarship make for an effective challenge to mainstream economics.
