Allan Hobson provides a new and increasingly complete picture of how dreaming is created by the brain. Focusing on dreaming to explain the mechanisms of sleep, this book explores how the new science of dreaming is affecting theories in psychoanalysis, and how it is helping our understanding of the causes of mental illness.J. Allan Hobson investigates his own dreams to illustrate and explain some of the fascinating discoveries of modern sleep science, while challenging some of the traditionally accepted theories about the meaning of dreams. He reveals how dreaming maintains and develops the mind, why we go crazy in our dreams in order to avoid doing so when we are awake, and why sleep is not just good for health but essential for life.

    First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. This Introduction explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever changing.

    In this Very Short Introduction, leading authority Jonathan Slack offers a clear and informative overview of stem cells--what they are, what scientists do with them, what stem cell therapies are available today, and how they might be used in the future. Slack explains the difference between embryonic stem cells, which exist only in laboratory cultures, and tissue-specific stem cells, which exist in our bodies, and he discusses how embryonic stem cells may be used in the future to treat such illnesses as diabetes, Parkinson's disease, heart disease, spinal trauma, and retinal degeneration. But he stresses that, despite important advances, the clinical applications of stem cells are still in their infancy and that most real stem cell therapy today is some form of bone marrow transplantation. Slack concludes by analyzing how medical innovation has occurred in this area in recent years and he draws out some of the lessons for the development of new therapies in the future.

    These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction gives a non-technical account of how drugs act on the body and how therapeutic drugs are developed and tested, then goes on to review both legal (prescription, alcohol, nicotine, and caffeine) and illegal drugs, and discuss current ideas about why some drugs are addictive, and whether drug laws need reform.

    Yet there is much more to the debate than theclash of these extremes. As Thomas Dixon shows in this balanced and thought-provoking introduction, a whole range of views, subtle arguments, and fascinating perspectives can be found on this complex and centuries-old subject. He explores the key philosophical questions that underlie the debate, but also highlights the social, political, and ethical contexts that have made the tensions between science and religion such a fraught and interesting topic in the modern world. Dixon emphasizes how the modern conflict between evolution and creationism is quintessentially an American phenomenon, arising from the culture and history of the United States, as exemplified through the ongoing debates about how to interpret the First-Amendment's separation of church and state. Along the way, he examines landmark historical episodes such as the Galileo affair, Charles Darwin's own religious andscientific odyssey, the Scopes Monkey Trial in Tennessee in 1925, and the Dover Area School Board case of 2005, and includes perspectives from non-Christian religions and examples from across the physical, biological, and social sciences.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundredsof key topics, from philosophy to Freud, quantum theory to Islam.

    Supreme Court and its justices as a correspondent for the New York Times. In this Very Short Introduction, she draws on her deep knowledge of the court's history and of its written and unwritten rules to show readers how the Supreme Court really works.Greenhouse offers a fascinating institutional biography of a place and its people--men and women who exercise great power but whose names and faces are unrecognized by many Americans and whose work often appears cloaked in mystery. How do cases get to the Supreme Court? How do the justices go about deciding them? What special role does the chief justice play? What do the law clerks do? How does the court relate to the other branches of government? Greenhouse answers these questions by depicting the justices as they confront deep constitutional issues or wrestle with the meaning of confusing federal statutes. Throughout, the author examines many individual Supreme Court cases to illustrate points under discussion, ranging from Marbury v. Madison, the seminal case which established judicial review, to the recent District of Columbia v. Heller (2008), which struck down the District of Columbia's gun-control statute and which was, surprisingly, the first time in its history that the Court issued an authoritative interpretation of the Second Amendment. To add perspective, Greenhouse also compares the Court to foreign courts, revealing interesting differences. For instance, no other country in the world has chosen to bestow life tenure on its judges.A superb overview packed with telling details, this volume offers a matchless introduction to one of the pillars of American government.

    Now, in The American Presidency, presidential authority Charles O. Jones provides invaluable background to the current controversy, in a compact, reliable guide to the office of the chief executive.This marvelously concise survey is packed with information about the presidency, some of it quite surprising. We learn, for example, that the Founders adopted the word president over governor and other alternatives because it suggested a light hand, as in one who presides, rather than rules. Indeed, the Constitutional Convention first agreed to a weak chief executive elected by congress for one seven-year term, later calling for independent election and separation of powers. Jones sheds much light on how assertive leaders, such as Andrew Jackson, Theodore Roosevelt, and FDR enhanced the power of the presidency, and illuminating how such factors as philosophy (Reagan's anti-Communist conservatism), the legacy of previous presidencies (Jimmy Carter following Watergate), relations with Congress, and the impact of outside events have all influenced presidential authority. He also explores the rise of federal power and the dramatic expansion of federal agencies, showing how the president takes a direct hand in this vast bureaucracy, and he examines the political process of selecting presidents, from the days of deadlocked conventions to the rise of the primary after World War II.In 200 years, he writes, the presidency had changed from that of a person--Washington followed by Adams, then Jefferson--to a presidential enterprise with a cast of thousands. Jones explains how this remarkable expansion has occurred and where it may lead in the future.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Plants have also become essential to humans not only in the form of cereal crops, fruit, and vegetables, but in their many other uses in wood and paper, and in providing medicines. In this Very Short Introduction Timothy Walker, Director of the Botanical Gardens in Oxford, provides a concise account of the nature of plants, their variety and classification, their evolution, and their aesthetic and practical value, stressing the need for their conservation for future generations.

    Highlighting the historical development and continued relevance of borders, Alexander Diener and Joshua Hagen offer a powerful counterpoint to the idea of an imminent borderless world, underscoring the impact borders have on a range of issues, such as economic development, inter- and intra-state conflict, global terrorism, migration, nationalism, international law, environmental sustainability, and natural resource management. Diener and Hagen demonstrate how and why borders have been, are currently, and will undoubtedly remain hot topics across the social sciences and in the global headlines for years to come. This compact volume will appeal to a broad, interdisciplinary audience of scholars and students, including geographers, political scientists, anthropologists, sociologists, historians, international relations and law experts, as well as lay readers interested in understanding current events.

    This Very Short Introduction presents a succinct guide to the key episodes in that story - from the very origins of life four million years ago to the extraordinary diversity of species around the globe today.Beginning with an explanation of the controversies surrounding the birth of life itself, each following chapter tells of a major breakthrough that made new forms of life possible: including sex and multicellularity, hard skeletons, and the move to land. Along the way, we witness the greatest mass extinction, the first forests, the rise of modern ecosystems, and, most recently, conscious humans.Introducing ideas from a range of scientific disciplines, from evolutionary biology and earth history, to geochemistry, palaeontology, and systematics, Michael Benton explains how modern science pieces the evidence in this vast evolutionary puzzle together, to build up an accessible and up-to-date picture of the key developments in the history of life on earth.

    It asks questions such as: Do animals have moral rights? If so, what does this mean? What sorts of mental lives do animals have, and how should we understand welfare? By presenting models for understanding animals' moral status and rights, and examining their mental lives and welfare, David DeGrazia explores the implications for how we should treat animals in connection with our diet, zoos, and research. Animal Rights distinguishes itself by combining intellectual rigor with accessibility, offering a distinct moral voice with a non-polemical tone.

    He charts life in Roman Britain from the first Roman invasion under Julius Caesar to the final collapse of the Roman Empire in the West around AD 500.

    In this thought-provoking exploration of the subject, Steve Edwards provides a clear, lively, and imaginative approach to the definition, importance, and meaning of photography. He combines a sense of its historical development with an analysis of its purpose and meaning within a wider cultural context. Edwards also discusses both well-known and more unusual photos, from the highly controversial Cottingley Fairies to Ansel Adams landscapes, and from the shocking and influential Eddie Adams image of a Vietcong suspect being executed to the portrait/performance art work of Cindy Sherman. Edwards interrogates the way we look and think about photographs, and considers such issues as truth and recording, objectivity and fine art, identity and memory.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.
