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.

    Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched. This is not some alternative universe but the realm of the very small, where quantum mechanics rules. In this weird world of atoms and their constituents, our common sense understanding of reality breaks down - yet quantum mechanics has never failed an experimental test. What does it all mean? For all its weirdness, quantum mechanics has given us many practical technologies including lasers and the transistors that underlie computers and all digital technology. In the future, it promises computers more powerful than any built before, the ability to communicate with absolute privacy, and even quantum teleportation. The Quantum World explores the past, present and future of quantum science, its applications and mind-bending implications. Discover how ideas from quantum mechanics are percolating out into the vast scale of the cosmos - perhaps, in the future, to reveal a new understanding of the big bang and the nature of space and time.ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds.

    The first abnormal psychology book to present a thoroughly integrated multicultural perspective--based on the authors' view that cross-cultural comparisons can greatly enhance the understanding of disorders--the text provides extensive coverage and integration of multicultural models, explanations, and concepts. The book also helps you gain an understanding of abnormal behavior as scientific and clinical endeavors, while providing insight into the tools that mental health professionals use to study and treat disorders.

    The nineteenth century experienced an explosion of epidemics such as cholera and diphtheria, driven by industrialization, urbanization and poor hygiene. In this pre-color-photography era, accurate images were relied upon to teach students and aid diagnosis. The best examples, featured here, are remarkable pieces of art that attempted to elucidate the mysteries of the body, and the successive onset of each affliction. Bizarre and captivating images, including close-up details and revealing cross-sections, make all too clear the fascinations of both doctors and artists of the time. Barnett illuminates the fears and obsessions of a society gripped by disease, yet slowly coming to understand and combat it. The age also saw the acceptance of vaccination and the germ theory, and notable diagrams that transformed public health, such as John Snow's cholera map and Florence Nightingale's pioneering histograms, are included and explained. Organized by disease, "The Sick Rose" ranges from little-known ailments now all but forgotten to the epidemics that shaped the modern age. It is a fascinating "Wunderkammer" of a book that will enthrall artists, students, designers, scientists and the incurably curious everywhere.
