Hagfish that can instantaneously produce oodles of gooey, slippery slime; frogs that poke their own toe bones through their skin to create claws; young birds that shoot streams of stinking poop; and more.
If a black dog and a white dog have puppies, what color will the puppies be? Genetic scientists have been trying to answer this question for hundreds of years. Genetics is the science of heredity—how traits are passed from parents to offspring. One of the first breakthroughs came from Gregor Mendel, a nineteenth-century monk who spent eight years breeding thousands of pea plants. Pea plants might seem pretty different from dogs, but on a microscopic level, they have a surprising amount in common. Genetic pioneers of the twentieth century unlocked the secrets of DNA, the molecule that holds heredity information for all life-forms. Thjis book tells the story of how scientists cracked the code of life and revolutionized molecular biology.

Allocation of natural resources has become a prominent concern at the local, state, and federal level. Competing uses for increasingly scarce resources are requiring that the relative values of those uses be investigated. Although many types of value are important in decision making, this book is concerned with the economic value of natural resources. Economic values for certain natural resources are readily observable in markets. For others, however, market prices are not available, and estimates of value must be made through nonmarket valuation techniques. The progress that has been made in improving the theory, methods, and applications of these techniques has been remarkable. Along with the progress, however, come new problems that must be addressed. The chapters presented in this volume are a collection of examples of both progress and problems.
After the 1986 Chernobyl nuclear explosion in Ukraine, scientists believed radiation had created a vast and barren wasteland in which life could never resurface. But the Dead Zone, as the contaminated area is known, doesn't look dead at all. In fact, wildlife seems to be thriving there. The Zone is home to beetles, swallows, catfish, mice, voles, otters, beavers, wild boar, foxes, lynx, deer, moose—even brown bears and wolves. Yet the animals in the Zone are not quite what you'd expect. Every single one of them is radioactive. In Chernobyl's Wild Kingdom, you'll meet the international scientists investigating the Zone's wildlife and trying to answer difficult questions: Have some animals adapted to living with radiation? Or is the radioactive environment harming them in ways we can't see or that will only show up in future generations? Learn more about the fascinating ongoing research—and the debates that surround the findings—in one of the most dangerous places on Earth.
A resource organized by body system lists the key herbal remedies available, their uses, and cautionary advice, in a book that includes full-color photos, a glossary and several thematic indexes.
Examining writing for and about education in the period from 1740 to 1820, Rebecca Davies’s book plots the formation of a written paradigm of maternal education that associates maternity with educational authority. Examining novels, fiction for children, conduct literature and educative and political tracts by Samuel Richardson, Sarah Fielding, Mary Wollstonecraft, Maria Edgeworth, Ann Martin Taylor and Jane Austen, Davies identifies an authoritative feminine educational voice. She shows how the function of the discourse of maternal authority is modified in different genres, arguing that both the female writers and the fictional mothers adopt maternal authority and produce their own formulations of ideal educational methods. The location of idealised maternity for women, Davies proposes, is in the act of writing educational discourse rather than in the physical performance of the maternal role. Her book contextualizes the development of a written discourse of maternal education that emerged in the enlightenment period and explores the empowerment achieved by women writing within this discourse, albeit through a notion of authority that is circumscribed by the 'rules' of a discipline.

For hundreds of years, people found the fossils of ancient sea creatures at the tops of tall mountains. Scientists puzzled over this problem. A fish couldn't have swum up a mountain. And how could rocks on a mountain move up from the bottom of a sea? Geologists finally found the answers they needed in the 1960s, when they developed the theory of plate tectonics. This theory revolutionized our understanding of the earth. Plate tectonics explains how volcanoes form, why earthquakes happen, and what goes on deep inside the earth to make the continents move. This book tells the story of scientists and their discoveries to explain how the theory of plate tectonics came to be.
