This riveting work of investigative reporting and history exposes classified government projects to build gravity-defying aircraft--which have an uncanny resemblance to flying saucers.The atomic bomb was not the only project to occupy government scientists in the 1940s. Antigravity technology, originally spearheaded by scientists in Nazi Germany, was another high priority, one that still may be in effect today. Now for the first time, a reporter with an unprecedented access to key sources in the intelligence and military communities reveals suppressed evidence that tells the story of a quest for a discovery that could prove as powerful as the A-bomb.The Hunt for Zero Point explores the scientific speculation that a "zero point" of gravity exists in the universe and can be replicated here on Earth. The pressure to be the first nation to harness gravity is immense, as it means having the ability to build military planes of unlimited speed and range, along with the most deadly weaponry the world has ever seen. The ideal shape for a gravity-defying vehicle happens to be a perfect disk, making antigravity tests a possible explanation for the numerous UFO sightings of the past 50 years.Chronicling the origins of antigravity research in the world's most advanced research facility, which was operated by the Third Reich during World War II, The Hunt for Zero Point traces U.S. involvement in the project, beginning with the recruitment of former Nazi scientists after the war. Drawn from interviews with those involved with the research and who visited labs in Europe and the United States, The Hunt for Zero Point journeys to the heart of the twentieth century's most puzzling unexplained phenomena.

It was August 27, 1885. In a hospital in Lima, Peru, a student named Daniel Carrión was preparing to infect himself with a dreaded disease . . . He had a small, sharp lancet ready . . . Carrión's friends and teacher from the medical school thought it was a bad idea. They knew Carrión was eager to learn more about this mysterious disease. But were the risks worth it?Science and medicine from the inside out-ten engrossing stories of self-experimentationWho are these "guinea pig scientists"? Searching for clues to some of science's and medicine's bigger (and sometimes stranger) questions, they are all the men and women who devoted their lives to help find the answers. Spanning from the 1770s to the present-and uncovering the science behind digestion, the spread of yellow fever, the development of the first heart catheter, and more-their ten stories are at once scientifically detailed and fascinatingly personal.

For anyone who is trying to keep up with the extremely rapid developments in the biodiesel industry, the second edition of Biodiesel: Growing a New Energy Economy is an invaluable aid. The breathtaking speed with which biodiesel has gained acceptance in the marketplace in the past few years has been exceeded only by the proliferation of biodiesel production facilities around the United States--and the world--only to confront new social and environmental challenges and criticisms.The international survey of the biodiesel industry has been expanded from 40 to more than 80 countries, reflecting the spectacular growth of the industry around the world. This section also tracks the dramatic shifts in the fortunes of the industry that have taken place in some of these nations. The detailed chapters that cover the industry in the United States have also been substantially rewritten to keep abreast of its many new developments and explosive domestic growth. An expanded section on small-scale, local biodiesel production has been added to better represent this small but growing part of the industry. Another new section has been added to more fully explore the increasingly controversial issues of deforestation and food versus fuel, as well as GMO crops. The second edition concludes with updated views on where the industry is headed in the years to come from some of its key players.

May 18, 1980, 8:32 A.M.: An earthquake suddenly triggered an avalanche on Mount St. Helens, a volcano in southern Washington State. Minutes later, Mount St. Helens blew the top off its peak and exploded into the most devastating volcanic eruption in U.S. history. What caused the eruption? What was left when it ended? What did scientists learn in its aftermath? In this extraordinary photographic essay, Patricia Lauber details the Mount St. Helens eruption and the years following. Through this clear accurate account, readers of all ages will share the awe of the scientists who witnessed both the power of the volcano and the resiliency of life.

Carjacked  is an in-depth look at our obsession with cars. While the automobileâs contribution to global warming and the effects of volatile gas prices is widely known, the problems we face every day because of our cars are much more widespread and yet much less known -- from the surprising $14,000 that the average family pays each year for the vehicles it owns, to the increase in rates of obesity and asthma to which cars contribute, to the 40,000 deaths and 2.5 million crash injuries each and every year.Carjacked details the complex impact of the automobile on modern society and shows us how to develop a healthier, cheaper, and greener relationship with cars.                                                            http://www.carjacked.org/

For a century, the Bath Iron Works has been building some of the finest, dealiest ships in the U.S. Navy. But now the Maine shipyard is facing mounting competition and a pressing need to modernize, especially in the way it launches ships. No more will the great gray leviathans roar down the "ways" -- the traditional inclined ramp -- into the Kennebec River; this ancient technology will give way to the modern dry dock.The Yard captures this moment of change and the end of an era, as old ways give way to new, through the eyes of the workers as they build and launch a U.S. Navy destroyer. From the first cutting of steel to the destroyer's triumphant commisioning, Michael Sanders chronicles the complex evolution of a ship coming into being -- and the incredible world in which it happens. It is a world rich in danger, humor, and lore, one filled with uncertainty, hope, and not a little fear of change as this venerable company fights against steep odds to find its place in a new world.

This eye-opening book describes how modern technologies--such as computers, automobiles, machine tools, hybrid crops, nuclear reactors, and others--contribute to vexing social problems ranging from the continued subordination of women and workers to widespread political disengagement. Engineers, manufacturers, and policy makers rarely take these consequences into account. Contending that reinvigorated democratic politics can and should supersede conventional economic reasoning as a basis for decisions about technology, Richard Sclove clearly outlines how the general public can become actively involved in all phases of technology decision making, from assessment and policy making to research and development.
