Most prisons are notorious for the quality of their cuisine (pretty poor) and the behavior of their residents (pretty violent). They are therefore ideal locations to test a novel hypothesis: that violent aggression is largely a product of poor nutrition. Toward that end, researchers are studying whether inmates become less violent when put on a diet rich in vitamins and in the fatty acids found in seafood. Could a salmon steak and a side of spinach really help curb violence, not just in prison but everywhere?

From Publishers Weekly Starred Review. This new entry in the Art of Mentoring series takes the form of letters from a fictitious mathematician to his niece. The letters span a period of 20 years, from the time the niece is thinking about studying mathematics in high school through the early years of her academic career. The format works wonderfully to introduce readers to the basics of the discipline of mathematics while providing a sense of what mathematicians actually do. Throughout, the prolific and talented Stewart (Does God Play Dice?), a British mathematician, entertains while educating. He explains how mathematics is so much more than mere calculations and how it's used in almost every facet of our lives. He also discusses the beauty mathematicians can find in the natural world, demonstrating that a focus on numbers and patterns can enhance rather than detract from an aesthetic appreciation of the environment. Stewart also does a superb job of examining the nature and value of both applied research and pure research, which, he shows, are not nearly as disparate as many think. Although the book must be read by anyone thinking about a career in mathematics, others simply interested in learning about the field and how mathematicians think will find it compelling reading.

Stop worrying about Avian flu already! According to a significant study published in the prestigious British journal Nature recently, the H5N1 bird flu virus is at least two large mutations and two small mutations away from being the next human pandemic virus. This virus attaches deep in the lungs of birds but cannot adhere to the upper respiratory tract of humans. Since we can't transmit the virus to each other, it poses little immediate threat to us. So why did the "flu hunter," world-renowned Tennessee virologist Robert Webster, say of bird flu on ABC that there are "about even odds at this time for the virus to learn how to transmit human to human," and that "society just can't accept the idea that 50 percent of the population could die . . . I'm sorry if I'm making people a little frightened, but I feel it's my role." I'm sorry, Dr. Webster, but your role is to track influenza in the test tube, not to enter into broad speculation on national television. By your way of thinking, we should all be either building an escape rocket ship or killing every bird we see before it can kill us.

Genetic engineering, nanotechnology, astrophysics, particle physics: We live in an engineered world, one where the distinctions between science and engineering, technology and research, are fast disappearing. This book shows how, at the dawn of the twenty-first century, the goals of natural scientists--to discover what was not known--and that of engineers--to create what did not exist--are undergoing an unprecedented convergence. Sunny Y. Auyang ranges widely in demonstrating that engineering today is not only a collaborator with science but its equal. In concise accounts of the emergence of industrial laboratories and chemical and electrical engineering, and in whirlwind histories of the machine tools and automobile industries and the rise of nuclear energy and information technology, her book presents a broad picture of modern engineering: its history, structure, technological achievements, and social responsibilities; its relation to natural science, business administration, and public policies. Auyang uses case studies such as the development of the F-117A Nighthawk and Boeing 777 aircraft, as well as the experiences of engineer-scientists such as Oliver Heaviside, engineer-entrepreneurs such as Henry Ford and Bill Gates, and engineer-managers such as Alfred Sloan and Jack Welch to give readers a clear sense of engineering's essential role in the future of scientific research.

Memory Practices in the Sciences |

The way we record knowledge, and the web of technical, formal, and social practices that surrounds it, inevitably affects the knowledge that we record. The ways we hold knowledge about the past -- in handwritten manuscripts, in printed books, in file folders, in databases -- shape the kind of stories we tell about that past. In this lively and erudite look at the relation of our information infrastructures to our information, Geoffrey Bowker examines how, over the past two hundred years, information technology has converged with the nature and production of scientific knowledge. His story weaves a path between the social and political work of creating an explicit, indexical memory for science -- the making of infrastructures -- and the variety of ways we continually reconfigure, lose, and regain the past. At a time when memory is so cheap and its recording is so protean, Bowker reminds us of the centrality of what and how we choose to forget. In Memory Practices in the Sciences he looks at three "memory epochs" of the nineteenth, twentieth, and twenty-first centuries and their particular reconstructions and reconfigurations of scientific knowledge. The nineteenth century's central science, geology, mapped both the social and the natural world into a single time package (despite apparent discontinuities), as, in a different way, did mid-twentieth-century cybernetics. Both, Bowker argues, packaged time in ways indexed by their information technologies to permit traffic between the social and natural worlds. Today's sciences of biodiversity, meanwhile, "database the world" in a way that excludes certain spaces, entities, and times. We use the tools of the present to look at the past, says Bowker; we project onto nature our modes of organizing our own affairs.

In the age of global biotechnology, DNA can exist as biological material in a test tube, as a sequence in a computer database, and as economically valuable information in a patent. In The Global Genome, Eugene Thacker asks us to consider the relationship of these three entities and argues that -- by their existence and their interrelationships -- they are fundamentally redefining the notion of biological "life itself." Biological science and the biotech industry are increasingly organized at a global level, in large part because of the use of the Internet in exchanging biological data. International genome sequencing efforts, genomic databases, the development of World Intellectual Property policies, and the "borderless" business of biotech are all evidence of the global intersections of biology and informatics -- of genetic codes and computer codes. Thacker points out the internal tension in the very concept of biotechnology: the products are more "tech" than "bio," but the technology itself is fully biological, composed of the biomaterial labor of genes, proteins, cells, and tissues. Is biotechnology a technology at all, he asks, or is it a notion of "life itself" that is inseparable from its use in the biotech industry? The three sections of the book cover the three primary activities of biotechnology today: the encoding of biological materials into digital form -- as in bioinformatics and genomics; its recoding in various ways -- including the "biocolonialism" of mapping genetically isolated ethnic populations and the newly pervasive concern over "biological security"; and its decoding back into biological materiality -- as in tissue engineering and regenerative medicine. Thacker moves easily from science to philosophy to political economics, enlivening his account with ideas from such thinkers as Georges Bataille, Georges Canguilhem, Michel Foucault, Antonio Negri, and Paul Virilio. The "global genome," says Thacker, makes it impossible to consider biotechnology without the context of globalism. Eugene Thacker is Assistant Professor in the School of Literature, Communication, and Culture at the Georgia Institute of Technology. "The book ambitiously tries to follow the ever-expanding ripples the genetic code is propaganding in the pond of civilization.... Thacker's is an interesting mind that wanders in and explores many directions. The Global Genome is a book likely to trigger very different thoughts, associations, and reactions from each reader." -- Science

In Biotech, Eric J. Vettel chronicles the story behind genetic engineering, recombinant DNA, cloning, and stem-cell research. It is a story about the meteoric rise of government support for scientific research during the Cold War, about activists and student protesters in the Vietnam era pressing for a new purpose in science, about politicians creating policy that alters the course of science, and also about the release of powerful entrepreneurial energies in universities and in venture capital that few realized existed. Most of all, it is a story about people—not just biologists but also followers and opponents who knew nothing about the biological sciences yet cared deeply about how biological research was done and how the resulting knowledge was used. Vettel weaves together these stories to illustrate how the biotechnology industry was born in the San Francisco Bay area, examining the anomalies, ironies, and paradoxes that contributed to its rise. Culled from oral histories, university records, and private corporate archives, including Cetus, the world's first biotechnology company, this compelling history shows how a cultural and political revolution in the 1960s resulted in a new scientific order: the practical application of biological knowledge supported by private investors expecting profitable returns eclipsed basic research supported by government agencies.
