    The first small cities formed not only the cradle of civilization, but the spawning ground for the earliest viral epidemics, the first opportunity for viruses to find a home in the human herd. This is a story of fear and ignorance, as everything from demons and the wrath of the gods to minority groups have been blamed for epidemics from smallpox to yellow fever to AIDS. It is a story of grief and heartbreak, as hundreds of thousands, sometimes millions, are wiped out in a single year. And it is a story of great bravery and sacrifice, as doctors and nurses put themselves in harm's way to combat yellow fever in Memphis and Ebola in Zaire, and as researchers risk their own lives to test theories of vaccines and the transmission of disease. Now, in Viruses, Plagues, and History, Michael B. A. Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity.Oldstone focuses his tale on a few of the most famous viruses humanity has battled, beginning with some we have effectively defeated, such as smallpox, polio, and measles. Nearly 300 million people were killed by smallpox in this century alone -- more than were killed in all the wars of the twentieth century combined. The author presents a vivid account of the long campaign against the virus, the insightful work of Edward Jenner, who created the smallpox vaccine from cowpox virus in 1796, and the monumental efforts of D. A. Henderson and an army of W.H.O. health care workers to finally eradicate smallpox. The smallpox virus remains the only organism that we have deliberately pushed to complete extinction in the wild.Oldstone then describes the fascinating viruses that have captured headlines in more recent years: Ebola and other hemorrhagic fevers, which literally turn their victims' organs to a bloody pulp; the Hantavirus outbreaks in the southwestern United States and elsewhere; mad cow disease, a frightening illness made worse by government mishandling and secrecy; and, of course, AIDS, often called the plague of our time. And he tells us of the many scientists watching and waiting even now for the next great plague, monitoring influenza strains to see whether the deadly variant from 1918 -- a viral strain that killed over 20 million people in 1918-1919, more than twice the military and civilian casualties of the First World War -- will make a comeback.Viruses have enormous power. They have wiped out cities, brought down dynasties, and helped destroy civilizations. But, as Michael Oldstone reveals, scientific research has given us the power to tame many of these viruses as well. Viruses, Plagues, and History shows us the panorama of humanity's long-standing conflict with our unseen viral enemies, from our successes to our continuing struggles. Oldstone's book is a vivid history of a fascinating field, and a highly reliable dispatch from a worker on the frontiers of this ongoing campaign.

    As a result, antibiotic resistance now ranks among the gravest medical problems of modern times. Good Germs, Bad Germs addresses not only this issue but also what has become known as the "hygiene hypothesis"-- an argument that links the over-sanitation of modern life to now-epidemic increases in immune and other disorders. In telling the story of what went terribly wrong in our war on germs, Jessica Snyder Sachs explores our emerging understanding of the symbiotic relationship between the human body and its resident microbes--which outnumber its human cells by a factor of nine to one! The book also offers a hopeful look into a future in which antibiotics will be designed and used more wisely, and beyond that, to a day when we may replace antibacterial drugs and cleansers with bacterial ones--each custom-designed for maximum health benefits.

    Vaccines and antibiotics, the mainstays of modern medicine, have not been able to conquer infectious microbes because of their amazing ability to adapt, evolve, and spread to new places. Terrorism aside, one of the greatest dangers from infectious disease we face today is from a massive outbreak of drug-resistant microbes.Deadly Outbreaks recounts the scientific adventures of a special group of intrepid individuals who investigate these outbreaks around the world and figure out how to stop them. Part homicide detective, part physician, these medical investigators must view the problem from every angle, exhausting every possible source of contamination. Any data gathered in the field must be stripped of human sorrows and carefully analyzed into hard statistics.Author Dr. Alexandra Levitt is an expert on emerging diseases and other public health threats. Here she shares insider accounts she’s collected that go behind the alarming headlines we’ve seen in the media: mysterious food poisonings, unexplained deaths at a children’s hospital, a strange neurologic disease afflicting slaughterhouse workers, flocks of birds dropping dead out of the sky, and drug-resistant malaria running rampant in a refugee camp. Meet the resourceful investigators—doctors, veterinarians, and research scientists—and discover the truth behind these cases and more.

    Understand how to use groundbreaking science to improve your health, mood, and more.In just the last few years, scientists have shown how the microscopic ecosystem within our bodies—particularly within our intestines—has an astonishing impact on our lives. Pioneering scientist Rob Knight and award-winning science journalist Brendan Buhler explain—with humor and witty metaphors—why these new findings matters to everyone.You are mostly not you. The human gut is host to trillions of microbes, and evidence shows that small changes in these microbes present (altered by antibiotics, diet, geographic region, and so on) may affect weight, likelihood of disease, and even psychological factors like risk-taking behavior. The evidence for their influence is astonishing. Rob Knight is one of the key figures driving forward this new science. His work demonstrates the startling connection between the presence of certain harmless bacteria and the health benefits we all seek for ourselves and our children.In Follow Your Gut, Knight pairs with Brendan Buhler, an award-winning science writer, to explore the previously unseen world inside our bodies. With a practical eye toward deeper knowledge and better decisions, they lead a detailed tour of our microbiome as well as an exploration of the known effects of antibiotics, probiotics, diet choices, birth method, and access to livestock on our children's lifelong health. Ultimately, this pioneering book explains how to learn about your own micro biome and take steps toward understanding and improving your health, using the latest research as a guide.

    That one bite changed her life forever, pulling her into the abyss of a devastating illness that took ten doctors to diagnose and years to recover: Newby had become one of the 300,000 Americans who are afflicted with Lyme disease each year.As a science writer, she was driven to understand why this disease is so misunderstood, and its patients so mistreated. This quest led her to Willy Burgdorfer, the Lyme microbe's discoverer, who revealed that he had developed bug-borne bioweapons during the Cold War, and believed that the Lyme epidemic was started by a military experiment gone wrong.In a superb, meticulous work of narrative journalism, Bitten takes readers on a journey to investigate these claims, from biological weapons facilities to interviews with biosecurity experts and microbiologists doing cutting-edge research, all the while uncovering darker truths about Willy. It also leads her to uncomfortable questions about why Lyme can be so difficult to both diagnose and treat, and why the government is so reluctant to classify chronic Lyme as a disease.A gripping, infectious page-turner, Bitten will shed a terrifying new light on an epidemic that is exacting an incalculable toll on us, upending much of what we believe we know about it.

    Over the last two decades, it has emerged as a powerful tool for solving crimes and determining guilt and innocence. But, very recently, an important new aspect of DNA has been revealed—it contains a detailed record of evolution. That is, DNA is a living chronicle of how the marvelous creatures that inhabit our planet have adapted to its many environments, from the freezing waters of the Antarctic to the lush canopy of the rain forest.In the pages of this highly readable narrative, Sean Carroll guides the general reader on a tour of the massive DNA record of three billion years of evolution to see how the fittest are made. And what a eye-opening tour it is—one featuring immortal genes, fossil genes, and genes that bear the scars of past battles with horrible diseases. This book clinches the case for evolution, beyond any reasonable doubt.

    

    Margulis to create a vivid new picture of the world that is crucial to our understanding of the future of the planet. Addressed to general readers, the book provides a beautifully written view of evolution as a process based on interdependency and the interconnectedness of all life on the planet.

    Written by an author team, including a Noble Prize winner, this text presents the integration of Mendelian and molecular principles, providing students with the links between early genetics understanding and the molecular discoveries that have changed the way the field of genetics is viewed.

    Beginning with a dramatic account of the SARS pandemic at the start of the 21st century, Dorothy Crawford takes us back in time to follow the interlinked history of microbes and humanity, offering an up-to-date look at ancient plagues and epidemics, and identifying key changes in the way humans have lived--such as our move from hunter-gatherer to farmer to city-dweller--which made us ever more vulnerable to microbe attack. Showing that how we live our lives today--with increased crowding and air travel--puts us once again at risk, Crawford asks whether we might ever conquer microbes completely. Among the possible answers, one thing becomes clear: that for generations to come, our deadly companions will continue to influence our lives. New in Paperback

    . . . The age of epigenetics has arrived."—Time, January 2010Epigenetic means "on the gene," and the term refers to the recent discovery that stress in the environment can impact an individual's physiology so deeply that those biological scars are actually inherited by the next several generations. For instance, a recent study has shown that men who started smoking before puberty caused their sons to have significantly higher rates of obesity. And obesity is just the tip of the iceberg—many researchers believe that epigenetics holds the key to understanding cancer, Alzheimer's, schizophrenia, autism, and diabetes.Epigenetics is the first book for general readers on this fascinating and important topic. The book is driven by stories such as the Dutch famine of World War II, José Canseco and steroids, the breeding of mules and hinnies, Tazmanian devils and contagious cancer, and more.
