Can genes determine which fifty-year-old will succumb to Alzheimer’s, which citizen will turn out on voting day, and which child will be marked for a life of crime? Yes, according to the Internet, a few scientific studies, and some in the biotechnology industry who should know better. Sheldon Krimsky and Jeremy Gruber gather a team of genetic experts to argue that treating genes as the holy grail of our physical being is a patently unscientific endeavor. Genetic Explanations urges us to replace our faith in genetic determinism with scientific knowledge about how DNA actually contributes to human development.

The concept of the gene has been steadily revised since Watson and Crick discovered the structure of the DNA molecule in 1953. No longer viewed by scientists as the cell’s fixed set of master molecules, genes and DNA are seen as a dynamic script that is ad-libbed at each stage of development. Rather than an autonomous predictor of disease, the DNA we inherit interacts continuously with the environment and functions differently as we age. What our parents hand down to us is just the beginning. Emphasizing relatively new understandings of genetic plasticity and epigenetic inheritance, the authors put into a broad developmental context the role genes are known to play in disease, behavior, evolution, and cognition.

Rather than dismissing genetic reductionism out of hand, Krimsky and Gruber ask why it persists despite opposing scientific evidence, how it influences attitudes about human behavior, and how it figures in the politics of research funding.

A thought-provoking examination of the intersections of knowledge and violence, and the quandaries and costs of modern, technoscientific warfare.

Science and violence converge in modern warfare. While the finest minds of the twentieth century have improved human life, they have also produced human injury. They engineered radar, developed electronic computers, and helped mass produce penicillin all in the context of military mobilization. Scientists also developed chemical weapons, atomic bombs, and psychological warfare strategies.

Rational Fog explores the quandary of scientific and technological productivity in an era of perpetual war. Science is, at its foundation, an international endeavor oriented toward advancing human welfare. At the same time, it has been nationalistic and militaristic in times of crisis and conflict. As our weapons have become more powerful, scientists have struggled to reconcile these tensions, engaging in heated debates over the problems inherent in exploiting science for military purposes. M. Susan Lindee examines this interplay between science and state violence and takes stock of researchers’ efforts to respond. Many scientists who wanted to distance their work from killing have found it difficult and have succumbed to the exigencies of war. Indeed, Lindee notes that scientists who otherwise oppose violence have sometimes been swept up in the spirit of militarism when war breaks out.

From the first uses of the gun to the mass production of DDT and the twenty-first-century battlefield of the mind, the science of war has achieved remarkable things at great human cost. Rational Fog reminds us that, for scientists and for us all, moral costs sometimes mount alongside technological and scientific advances.
