Between 1870 and 1940, life expectancy in the United States skyrocketed while the percentage of senior citizens age sixty-five and older more than doubled—a phenomenon owed largely to innovations in medicine and public health. At the same time, the Great Depression was a major tipping point for age discrimination and poverty in the West: seniors were living longer and retiring earlier, but without adequate means to support themselves and their families. The economic disaster of the 1930s alerted scientists, who were actively researching the processes of aging, to the profound social implications of their work—and by the end of the 1950s, the field of gerontology emerged. Old Age, New Science explores how a group of American and British life scientists contributed to gerontology's development as a multidisciplinary field. It examines the foundational "biosocial visions" they shared, a byproduct of both their research and the social problems they encountered. Hyung Wook Park shows how these visions shaped popular discourses on aging, directly influenced the institutionalization of gerontology, and also reflected the class, gender, and race biases of their founders.

Takes the reader on a voyage of discovery as the author traces a single mass of air traveling from the Canadian Rockies to the northeastern United States.

Many young Christians interested in the sciences have felt torn between two options: remaining faithful to Christ or studying science. In this concise introduction, Josh Reeves and Steve Donaldson provide both advice and encouragement for Christians in the sciences to bridge the gap between science and Christian belief and practice.

By the year 2050, Earth's population will double. If we continue with current farming practices, vast amounts of wilderness will be lost, millions of birds and billions of insects will die, and the public will lose billions of dollars as a consequence of environmental degradation. Clearly, there must be a better way to meet the need for increased food production. Written as part memoir, part instruction, and part contemplation, Tomorrow's Table argues that a judicious blend of two important strands of agriculture--genetic engineering and organic farming--is key to helping feed the world's growing population in an ecologically balanced manner. Pamela Ronald, a geneticist, and her husband, Raoul Adamchak, an organic farmer, take the reader inside their lives for roughly a year, allowing us to look over their shoulders so that we can see what geneticists and organic farmers actually do. The reader sees the problems that farmers face, trying to provide larger yields without resorting to expensive or environmentally hazardous chemicals, a problem that will loom larger and larger as the century progresses. They learn how organic farmers and geneticists address these problems. This book is for consumers, farmers, and policy decision makers who want to make food choices and policy that will support ecologically responsible farming practices. It is also for anyone who wants accurate information about organic farming, genetic engineering, and their potential impacts on human health and the environment.
