DOWNLOAD EBOOKIn their sometimes fierce, often mysterious day-to-day lives, many plants and animals rely on the transmission and reception of chemicals for the basic functions of attack, defense, eating, and avoidance of being eaten. This exciting and eminently readable book tells the story of the surprising interplay between the hunters and the hunted, and even the hunters of the hunters, in the gardens, fields, and forests of the world.

DOWNLOAD EBOOKThis could be the most important book you will read this year. Around the office at Chelsea Green it is referred to as the "pharmaceutical Silent Spring." Well-known author, teacher, lecturer, and herbalist Stephen Harrod Buhner has produced a book that is certain to generate controversy. It consists of three parts: A critique of technological medicine, and especially the dangers to the environment posed by pharmaceuticals and other synthetic substances that people use in connection with health care and personal body care. A new look at Gaia Theory, including an explanation that plants are the original chemistries of Gaia and those phytochemistries are the fundamental communications network for the Earth's ecosystems. Extensive documentation of how plants communicate their healing qualities to humans and other animals. Western culture has obliterated most people's capacity to perceive these messages, but this book also contains valuable information on how we can restore our faculties of perception. The book will affect readers on rational and emotional planes. It is grounded in both a New Age spiritual sensibility and hard science. While some of the author's claims may strike traditional thinkers as outlandish, Buhner presents his arguments with such authority and documentation that the scientific underpinnings, however unconventional, are completely credible. The overall impact is a powerful, eye-opening expos' of the threat that our allopathic Western medical system, in combination with our unquestioning faith in science and technology, poses to the primary life-support systems of the planet. At a time when we are preoccupied with the terrorist attacks and the possibility of biological warfare, perhaps it is time to listen to the planet. This book is essential reading for anyone concerned about the state of the environment, the state of health care, and our cultural sanity.

DOWNLOAD EBOOKAn analysis of convergent evolution from molecules to ecosystems, demonstrating the limited number of evolutionary pathways available to life. Charles Darwin famously concluded On the Origin of Species with a vision of “endless forms most beautiful” continually evolving. More than 150 years later many evolutionary biologists see not endless forms but the same, or very similar, forms evolving repeatedly in many independent species lineages. A porpoise's fishlike fins, for example, are not inherited from fish ancestors but are independently derived convergent traits. In this book, George McGhee describes the ubiquity of the phenomenon of convergent evolution and connects it directly to the concept of evolutionary constraint—the idea that the number of evolutionary pathways available to life are not endless, but quite limited. Convergent evolution occurs on all levels, from tiny organic molecules to entire ecosystems of species. McGhee demonstrates its ubiquity in animals, both herbivore and carnivore; in plants; in ecosystems; in molecules, including DNA, proteins, and enzymes; and even in minds, describing problem-solving behavior and group behavior as the products of convergence. For each species example, he provides an abbreviated list of the major nodes in its phylogenetic classification, allowing the reader to see the evolutionary relationship of a group of species that have independently evolved a similar trait by convergent evolution. McGhee analyzes the role of functional and developmental constraints in producing convergent evolution, and considers the scientific and philosophical implications of convergent evolution for the predictability of the evolutionary process.

DOWNLOAD EBOOKThe tobacco plant synthesizes nicotine to protect itself from herbivores. The female moth broadcasts sex pheromones to attract a mate, while a soldier ant deploys an alarm pheromone to call for help. The carbon dioxide on a mammal's breath beckons hungry ticks and mosquitoes, while a flower's fragrance speaks to the honey bee. Indeed, much of the communication that occurs within and between various species of organisms is done not by sight, sound, or touch, but with chemicals. From mating to parenting, foraging to self-defense, plant and animal activities are accomplished largely by the secretion or exchange of organic chemicals. The fascinating and fast-developing science that encompasses these diverse phenomena is introduced here, by William Agosta, in a series of remarkable stories absolutely accessible to the general reader yet revelatory to chemists and biologists. Among Agosta's characters are the organisms that steal, counterfeit, or interpret the chemical signals of other species for their own ends. We learn of seeds that mimic ant odors to facilitate their own dispersion and flies that follow the scent of truffles to lay their eggs. We read about pit vipers that react in terror when their flicking tongues detect a king snake, and slave-making ants incapable of finding their own food. And we meet ice-age people who ate birch fungus to relieve whipworms and early human hunters who used the urine of wolves to maneuver deer to favorable sites. Agosta also chronicles the rapid development of the applied science that makes use of chemical ecology. As researchers deepen our understanding of the biological world, they are making economically significant discoveries (such as enzymes that remain stable in extreme heat), finding ways to reduce our reliance on manufactured pesticides, identifying new uses for traditional medicines, and developing sophisticated new pharmaceuticals effective in treating malaria and several cancers. On the horizon are antiviral agents derived from the chemical defenses of marine species. From the exploits of flies to the high-stakes effort to cure human disease, Agosta's tour of chemical ecology grants any reader entrance to the invisible realm where chemistry determines life and death.

DOWNLOAD EBOOKInterest in green chemistry and clean processes has grown so much in recent years that topics such as fluorous biphasic catalysis, metal organic frameworks, and process intensification, which were barely mentioned in the First Edition, have become major areas of research. In addition, government funding has ramped up the development of fuel cells and biofuels. This reflects the evolving focus from pollution remediation to pollution prevention. Copiously illustrated with more than 800 figures, the Third Edition provides an update from the frontiers of the field. It features supplementary exercises at the end of each chapter relevant to the chemical examples introduced in each chapter. Particular attention is paid to a new concluding chapter on the use of green metrics as an objective tool to demonstrate proof of synthesis plan efficiency and to identify where further improvements can be made through fully worked examples relevant to the chemical industry. NEW AND EXPANDED RESEARCH TOPICS Metal-organic frameworks Metrics Solid acids for alkylation of isobutene by butanes Carbon molecular sieves Mixed micro- and mesoporous solids Organocatalysis Process intensification and gas phase enzymatic reactions Hydrogen storage for fuel cells Reactive distillation Catalysts in action on an atomic scale UPDATED AND EXPANDED CURRENT EVENTS TOPICS Industry resistance to inherently safer chemistry Nuclear power Removal of mercury from vaccines Removal of mercury and lead from primary explosives Biofuels Uses for surplus glycerol New hard materials to reduce wear Electronic waste Smart growth The book covers traditional green chemistry topics, including catalysis, benign solvents, and alternative feedstocks. It also discusses relevant but less frequently covered topics with chapters such as "Chemistry of Long Wear" and "Population and the Environment." This coverage highlights the importance of chemistry to everyday life and demonstrates the benefits the expanded exploitation of green chemistry can have for society.

DOWNLOAD EBOOKNATIONAL BESTSELLER • At once an incredible adventure narrative and a penetrating biographical portrait—the bestselling author of River of the Gods brings us the true story of Theodore Roosevelt’s harrowing exploration of one of the most dangerous rivers on earth. “A rich, dramatic tale that ranges from the personal to the literally earth-shaking.” —The New York Times The River of Doubt—it is a black, uncharted tributary of the Amazon that snakes through one of the most treacherous jungles in the world. Indians armed with poison-tipped arrows haunt its shadows; piranhas glide through its waters; boulder-strewn rapids turn the river into a roiling cauldron. After his humiliating election defeat in 1912, Roosevelt set his sights on the most punishing physical challenge he could find, the first descent of an unmapped, rapids-choked tributary of the Amazon. Together with his son Kermit and Brazil’s most famous explorer, Cândido Mariano da Silva Rondon, Roosevelt accomplished a feat so great that many at the time refused to believe it. In the process, he changed the map of the western hemisphere forever. Along the way, Roosevelt and his men faced an unbelievable series of hardships, losing their canoes and supplies to punishing whitewater rapids, and enduring starvation, Indian attack, disease, drowning, and a murder within their own ranks. Three men died, and Roosevelt was brought to the brink of suicide. The River of Doubt brings alive these extraordinary events in a powerful nonfiction narrative thriller that happens to feature one of the most famous Americans who ever lived. From the soaring beauty of the Amazon rain forest to the darkest night of Theodore Roosevelt’s life, here is Candice Millard’s dazzling debut. Look for Candice Millard’s latest book, River of the Gods.
