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.

    It is truly a vital field, central to the health of society, but it is often poorly understood, largely due to misrepresentations in the media. In this Very Short Introduction, an internationally recognized authority on epidemiology, Dr. Rodolfo Saracci, provides a wealth of information on this key field, dispelling some of the myths surrounding the study of epidemiology, and explaining what epidemiology is and how vital it is to the discovery, control, and prevention of disease in world populations. Dr. Saracci provides a general explanation of the principles behind clinical trials, and explains the nature of basic statistics concerning disease. He also looks at the ethical and political issues related to obtaining and using information concerning patients, and trials involving placebos.

    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.

    And while research into cancer is bringing huge improvements in the range of options available to cancer patients, these new therapies bring with them massive challenges for healthcare systems struggling to find the huge sums of money for the large numbers of patients involved. This Very Short Introduction explores the facts underlying these figures, starting with the basic facts about the disease before moving on to the bigger picture of the economics and politics of cancer care. Nick James, founder of the CancerHelp UK website, examines the trends in diagnosis of the disease and the constant improvements in treatment techniques that result in better cure rates and increased quality and quantity of life for cancer patients. The book also considers issues surrounding expensive drug development, highlights what can be done to reduce the risk of developing cancer, and discusses the use of complementary and alternative therapies.

    Mankind's battle to stay alive and healthy for as long as possible is our oldest, most universal struggle. With his characteristic wit and vastly informed historical scope, Roy Porter examines the war fought between disease and doctors on the battleground of the flesh from ancient times to the present. He explores the many ingenious ways in which we have attempted to overcome disease through the ages: the changing role of doctors, from ancient healers, apothecaries, and blood-letters to today's professionals; the array of drugs, from Ayurvedic remedies to the launch of Viagra; the advances in surgery, from amputations performed by barbers without anesthetic to today's sophisticated transplants; and the transformation of hospitals from Christian places of convalescence to modern medical powerhouses. Cleverly illustrated with historic line drawings, the chronic ailments of humanity provide vivid anecdotes for Porter's enlightening story of medicine's efforts to prevail over a formidable and ever-changing adversary.

    Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.
