Over the last century, the industrialization of agriculture and processing technologies have made food abundant and relatively inexpensive for much of the world's population. Simultaneously, pesticides, nitrates, and other technological innovations intended to improve the food supply's productivity and safety have generated new, often poorly understood risks for consumers and the environment. From the proliferation of synthetic additives to the threat posed by antibiotic-resistant bacteria, the chapters in Risk on the Table zero in on key historical cases in North America and Europe that illuminate the history of food safety, highlighting the powerful tensions that exists among scientific understandings of risk, policymakers' decisions, and cultural notions of "pure" food.

What useful changes has feminism brought to science? Feminists have enjoyed success in their efforts to open many fields to women as participants. But the effects of feminism have not been restricted to altering employment and professional opportunities for women. The essays in this volume explore how feminist theory has had a direct impact on research in the biological and social sciences, in medicine, and in technology, often providing the impetus for fundamentally changing the theoretical underpinnings and practices of such research. In archaeology, evidence of women's hunting activities suggested by spears found in women's graves is no longer dismissed; computer scientists have used feminist epistemologies for rethinking the human-interface problems of our growing reliance on computers. Attention to women's movements often tends to reinforce a presumption that feminism changes institutions through critique-from-without. This volume reveals the potent but not always visible transformations feminism has brought to science, technology, and medicine from within.

After World War II, the US Atomic Energy Commission (AEC) began mass-producing radioisotopes, sending out nearly 64,000 shipments of radioactive materials to scientists and physicians by 1955. Even as the atomic bomb became the focus of Cold War anxiety, radioisotopes represented the government's efforts to harness the power of the atom for peace-advancing medicine, domestic energy, and foreign relations. In Life Atomic, Angela N. H. Creager tells the story of how these radioisotopes, which were simultaneously scientific tools and political icons, transformed biomedicine and ecology. Government-produced radioisotopes provided physicians with new tools for diagnosis and therapy, specifically cancer therapy, and enabled biologists to trace molecular transformations. Yet the government's attempt to present radioisotopes as marvelous dividends of the atomic age was undercut in the 1950s by the fallout debates, as scientists and citizens recognized the hazards of low-level radiation. Creager reveals that growing consciousness of the danger of radioactivity did not reduce the demand for radioisotopes at hospitals and laboratories, but it did change their popular representation from a therapeutic agent to an environmental poison. She then demonstrates how, by the late twentieth century, public fear of radioactivity overshadowed any appreciation of the positive consequences of the AEC's provision of radioisotopes for research and medicine.

Physicists regularly invoke universal laws, such as those of motion and electromagnetism, to explain events. Biological and medical scientists have no such laws. How then do they acquire a reliable body of knowledge about biological organisms and human disease? One way is by repeatedly returning to, manipulating, observing, interpreting, and reinterpreting certain subjects-such as flies, mice, worms, or microbes-or, as they are known in biology, "model systems." Across the natural and social sciences, other disciplinary fields have developed canonical examples that have played a role comparable to that of biology's model systems, serving not only as points of reference and illustrations of general principles or values but also as sites of continued investigation and reinterpretation. The essays in this collection assess the scope and function of model objects in domains as diverse as biology, geology, and history, attending to differences between fields as well as to epistemological commonalities.Contributors examine the role of the fruit fly Drosophila and nematode worms in biology, troops of baboons in primatology, box and digital simulations of the movement of the earth's crust in geology, and meteorological models in climatology. They analyze the intensive study of the prisoner's dilemma in game theory, ritual in anthropology, the individual case in psychoanalytic research, and Athenian democracy in political theory. The contributors illuminate the processes through which particular organisms, cases, materials, or narratives become foundational to their fields, and they examine how these foundational exemplars-from the fruit fly to Freud's Dora-shape the knowledge produced within their disciplines.
