After the atomic bombing at the end of World War II, anxieties about survival in the nuclear age led scientists to begin stockpiling and freezing hundreds of thousands of blood samples from indigenous communities around the world. These samples were believed to embody potentially invaluable biological information about genetic ancestry, evolution, microbes, and much more. Today, they persist in freezers as part of a global tissue-based infrastructure. In Life on Ice, Joanna Radin examines how and why these frozen blood samples shaped the practice known as biobanking. The Biomedical Research Institute (BRI) and some of its early employees were key players in the development of the field and business of Cryobiology.
