Allen and Cowling start with the simple "prokaryotic" cell--cells with no nucleus--and show how the bodies of more complex plants and animals consist of billions of "eukaryotic" cells, of varying kinds, adapted to fill different roles--red blood cells, muscle cells, branched neurons. The authors also show that each cell is an astonishingly complex chemical factory, the activities of which we have only begun to unravel in the past fifty years.

    In this Very Short Introduction, eminent biologist and popular science writer Dorothy Crawford offers a fascinating portrait of these infinitesimally small but often highly dangerous creatures. Crawford first relates how viruses were discovered and she unravels the intricate structures of tiny parasites that are by far the most abundant life forms on the planet. Analyzing the threat of viral infections, Crawford recounts stories of renowned killer viruses such as Ebola and rabies as well as the less known bat-borne Nipah and Hendra viruses. She identifies wild animals as the source of the most recent pandemics, detailing the reasons behind the present increase in potentially fatal infections, and evaluating the evidence that suggests that long term viruses can eventually lead to cancer. Finally, Crawford looks to the future to ask whether we can ever live in harmony with viruses, and considers ways to prevent the emergence of new and devastating viruses.

    The book describes dramatic breakthroughs in our knowledge of how sleep occurs, what it does, and what happens to our health if we do not have enough. The authors consider the impact of modern society, examining the relationship between sleep and our 24/7 culture.

    But how much do these types of entertainment really tell us about recent scientific discoveries and the latest research into the world of the dinosaur?This is the first book explain how scientists have been able to put together a picture of how dinosaurs looked, what they ate, and how they moved and interacted with each other. Taking a new approach to the subject, David Norman combines different areas of science, such as anatomy, genetics, forensics, and engineering design, to piece together the latest evidence of how animal life evolved on earth. Norman engagingly lays out the history of dinosaur research, from the speculation over ancient myths about dragons, to the latest virtual reality animation sequences and engineering design analysis. He also discusses the role that informed speculation and luck has played in many of the major discoveries.This book is a fantastic introduction for those just beginning to take an interest in dinosaurs and a must-read for true dinosaur-lovers who want to know not just the latest theories and discoveries, but how scientists achieved them.

    Yet, the science underpinning this technology is less visible and little understood outside the professional computer science community. As a scientific discipline, computer science stands alongside the likes of molecular biology and cognitive science as one of the most significant new sciences of the post Second World War era.In this Very Short Introduction, Subrata Dasgupta sheds light on these lesser known areas and considers the conceptual basis of computer science. Discussing algorithms, programming, and sequential and parallel processing, he considers emerging modern ideas such as biological computing and cognitive modelling, challenging the idea of computer science as a science of the artificial.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    The growing number of patients being diagnosed with depression, ADD, alcoholism, and other illnesses mean that few people are not touched by it. This book provides a valuable and comprehensible introduction to the subject. It starts with the history of its development as a scientific field, including the identification of major mental illnesses, the rise and fall of the asylum system, and the flourishing of psychoanalysis and other psychotherapies. More than any other branch of medicine, psychiatry has been attacked and criticized. There is a long list of perceived horrors--patient abuse, bizarre medical experiments, mind-control by evil governments, coercion by maniacal hypnotists. Modern psychiatry brings with it new controversies, such as the perceived over-prescription of antidepressants and behavior modifiers for children and teens, or unchecked marketing power of drug companies. This book does not draw conclusions on these issues, but rather provides the reader with a clear understanding of what psychiatry is, and what it does, so that they can draw their own. It is a great reference for anyone with an interest in mental illness and its treatment, students of psychiatry, medicine, psychology, and history of science, and health professionals.

    Jan Westerhoff shows that the question "what is real?" is not some esoteric puzzle that only philosophers ponder. Scientists also ask this question when they investigate whether candidates for the fundamental constituents of matter are actually "out there" or just a mere abstraction from a successful theory and cognitive scientists ask it when trying to find out which set of the bewildering array of data processed by our brain could constitute the basis for the self.

    Agnosticism emerges here as a much more sophisticated, and much more interesting, attitude than a simple failure to either commit to, or reject, religious belief. Le Poidevin challenges the common wisdom about agnosticism among both believers and atheists, and invites the reader to rethink their own position on the issues. Indeed, in arguing in favor of agnosticism as a respectable position to take, this stimulating and provocative guide takes issue on many points with the assertions of prominent atheists such as Richard Dawkins.

    This short and accessible introduction provides an invaluable tool with which to think about the ethical values that lie at the heart of medicine.Tony Hope deals with thorny moral issues, including euthanasia and the morality of killing. He also explores political questions, such as how we can make sure health care resources are distributed fairly. Each chapter in the book considers a different issue, for example, genetics, modern reproductive technologies, resource allocation, mental health, and medical research. Each section also discusses controversial questions such as: Who should have access to reproductive technology? Is it right to fund expensive drug treatment for individuals? Should treatment for mental illness be imposed on patients without their consent? Considering a wide range of questions of medical ethics, this Very Short Introduction will help to explain some of the confusing issues facing the field of medicine today.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 hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    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.

    Moreover, groundbreaking research on genes, and especially key families of genes such as the Homeobox genes which controlthe development of body plans, has led to radical changes in the classification of animals. In this Very Short Introduction, Peter Holland presents a cutting-edge tour of the animal kingdom, providing an authoritative summary of the modern view of animal life, its origins, and the new classificationresulting from DNA studies. Beginning with the definition of animals (not obvious in biological terms), Holland takes the reader through the revolutionary new high-level groupings of animals (phyla) based on evolutionary relationships and ancestry. Ranging from corals and sponges to nematodes, seasquirts, and vertebrates, and illuminating many key topics in zoology, this fascinating, brief overview will be of great value to all students of the life sciences as well as providing a concise summary for the interested lay reader.

    Richard Tuck shows that while Hobbes may indeed have been an atheist, he was far from pessimistic about human nature, nor did he advocate totalitarianism. By locating him against the context of his age, we learn that Hobbes developed a theory of knowledge which rivaled that of Descartes in its importance for the formation of modern philosophy.

    This Very Short Introduction tells the story of Chinese literature from antiquity tothe present, focusing on the key role literary culture played in supporting social and political concerns. Embracing traditional Chinese understandings of literature as encompassing history and philosophy as well as poetry and poetics, storytelling, drama, and the novel, Sabina Knight discusses thephilosophical foundations of literary culture as well as literature's power to address historical trauma and cultivate moral and sensual passions. From ancient historical records through the modernization and globalization of Chinese literature, Knight draws on lively examples to underscore theclose relationship between ethics and aesthetics, as well as the diversity of Chinese thought. Knight also illuminates the role of elite patronage; the ways literature has served the interests of specific groups; and questions of canonization, language, nationalism, and cross-cultural understanding.The book includes Chinese characters for names, titles, and key terms.

    The punishment of crime, compensation of the injured, and the enforcement of contracts are merely some of the tasks of a modern legal system. It also strives to ensure justice, promote freedom, and protect our security. The result is a system that, while it touches all of our daily lives, is properly understood by only a few, with its impenetrable jargon, obsolete procedures, and interminable stream of Byzantine statutes and judgments of the courts. This clear, jargon-free Very Short Introduction cuts introduces the essentials of law and legal systems in a lively, accessible, and stimulating manner. Explaining the main concepts, terms, and processes of the legal system, it focuses on the Western tradition, but also examines other legal systems, such as customary law and Islamic law. And it looks to the future too, as globalization and rapid advances in technology place increasing strain on our current legal system.

    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.
