Transgenic crops offer the promise of increased agricultural productivity and better quality foods. But they also raise the specter of harmful environmental effects. In this new book, a panel of experts examines: a Similarities and differences between crops developed by conventional and transgenic methods a Potential for commercialized transgenic crops to change both agricultural and nonagricultural landscapes a How well the U.S. government is regulating transgenic crops to avoid any negative effects.
Environmental Effects of Transgenic Plants provides a wealth of...

The Internet has changed the way we access the world. This is especially true for kids, who soak up new technologies like eager little sponges. They have access to an enormous array of material, including educational links, sports info, chat roomsa "and, unfortunately, pornography. But we must approach our need to protect children with care to avoid placing unnecessary restrictions on the many positive features of the Internet.

National Academy Press National Research Council Committee on Ecosystem Effects of Fish
Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear--specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long--lived species are more vulnerable...

Dramatic developments in understanding the fundamental underpinnings of life have provided exciting opportunities to make marine bioproducts an important part of the U.S. economy. Several marine based pharmaceuticals are under active commercial development, ecosystem health is high on the public's list of concerns, and aquaculture is providing an ever greater proportion of the seafood on our tables. Nevertheless, marine biotechnology has not yet caught the public's, or investor's, attention. Two workshops, held in October 1999 and November 2001 at the National Academies, were successful in...

National Academy Press National Research Council Committee on Ungulate Management in Ye
Ecological Dynamics on Yellowstonea (TM)s Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Servicea (TM)s approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds.
This report examines the...

The Roundtable on Environmental Health Sciences, Research, and Medicine wanted to address the link between environmental factors and the development of cancer in light of recent advances in genomics. They asked what research tools are needed, how new scientific information can be applied in a timely manner to reduce the burden of cancer, and how this can be flexible enough to treat the individual.

Computer science has drawn from and contributed to many disciplines and practices since it emerged as a field in the middle of the 20th century. Those interactions, in turn, have contributed to the evolution of information technology a " new forms of computing and communications, and new applications a " that continue to develop from the creative interactions between computer science and other fields.
Beyond Productivity argues that, at the beginning of the 21st century, information technology (IT) is forming a powerful alliance with creative practices in the arts and design...

The growing consumer interest in health and fitness has expanded the market for a wide range of products, from yoga mats to the multiple dietary supplements now on the market. Supplements are popular, but are they safe? Many dietary supplements are probably safe when used as recommended. However, since 1994 when Congress decided that they should be regulated as if they were foods, they are assumed to be safe unless the Food and Drug Administration can demonstrate that they pose a significant risk to the consumer. But there are many types of products that qualify as dietary supplements, and...

"What is not debatable is the 'Uncertainty Modeling in Vibration, Control, and Fuzzy Analysis of Structural Systems', makes an important contribution to our understanding of how both probability-based and fuzzy-logic-based methods for modeling of uncertainty can be applied in the realm of vibration, control, structural analysis and related problem areas. The editors and contributors to information volume deserve our thanks and congratulations for producing a work, which is highly informative, authorative, up-to-date and reader-friendly." Prof. Lotfi A Zadeh University of California,...
