But AIDS is just one of the many emerging viruses for which we have, as yet, no cure. Even the old plagues – TB, cholera, bubonic plague – are making a comeback, resistant now to our drugs.Frank Ryan, a leading authority on disease, describes the groundbreaking research of the world’s leading experts in the field to show both where these viruses come from and why they prove to be so lethal, and advances a radical new biological theory for the origins and behaviour of plague viruses. Full of vivid despatches from the front line of research and medicine, 'Virus X' is terrifying and essential reading for anyone interested in the effects of plague viruses on human evolution.“Extremely well written…Frank Ryan has the page-turning and spine-chilling ability of a good novelist”MATT RIDLEY, 'Sunday Telegraph'“Compelling and frightening…the plot could not be bettered”MICHAEL SMITH, 'Scotsman'“Ryan is very good at making technical matters comprehensible to the lay reader but more impressive still is the way he conveys the intellectual excitement and elation of scientific discovery”ANTHONY DANIELS, 'Literary Review'“Ryan takes us through the drama of discovery and challenges the notion that certain questions are too appalling to contemplate”DAVID BRADLEY, 'New Scientist'“Dr Ryan writes well in a difficult technical field, weaving the technicalities of scientific history, medicine, molecular biology and evolution into the human narratives…very readable and disturbing”JOHN R.G. TURNER, 'New York Times'

    Offit, M.D., a scathing exposé of the alternative medicine industry, revealing how even though some popular therapies are remarkably helpful due to the placebo response, many of them are ineffective, expensive, and even deadlyIn Do You Believe in Magic?, Paul Offit, M.D., reveals how alternative medicine—an unregulated industry under no legal obligation to prove its claims or admit its risks—can actually be harmful to our health.Using dramatic real-life stories, Offit separates the sense from the nonsense, showing why any therapy—alternative or traditional—should be scrutinized. He also shows how some nontraditional methods can do a great deal of good, in some cases exceeding therapies offered by conventional practitioners.An outspoken advocate for science-based health advocacy who is not afraid to take on media celebrities who promote alternative practices, Dr. Offit advises, “There’s no such thing as alternative medicine. There’s only medicine that works and medicine that doesn’t.”

    She focuses on a different danger in each chapter-from the looming risk of lethal influenza to in-depth information on the public health perils posed by bioterrorism. With a novelist's descriptive eye and a thriller writer's sense of tension, she warns us that the most ceaselessly creative bioterrorist is still Mother Nature, whose microbial operatives are all around us, ready to pounce when conditions are right.

    Lieberman illuminates how these ongoing changes have brought many benefits, but also have created novel conditions to which our bodies are not entirely adapted, resulting in a growing incidence of obesity and new but avoidable diseases, including type-2 diabetes. He proposes that many of these chronic illnesses persist and in some cases are intensifying because of "dysevolution," a pernicious dynamic whereby only the symptoms rather than the causes of these maladies are treated. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes oblige us to create a more salubrious environment.(With charts and line drawings throughout.)From the Hardcover edition.

    His passing on March 6, 1900, would have been unremarkable if a city health officer hadn’t noticed a swollen black lymph node on his groin—a sign of bubonic plague. Empowered by racist pseudoscience, officials rushed to quarantine Chinatown while doctors examined Wong’s tissue for telltale bacteria. If the devastating disease was not contained, San Francisco would become the American epicenter of an outbreak that had already claimed ten million lives worldwide.To local press, railroad barons, and elected officials, such a possibility was inconceivable—or inconvenient. As they mounted a cover-up to obscure the threat, ending the career of one of the most brilliant scientists in the nation in the process, it fell to federal health officer Rupert Blue to save a city that refused to be rescued. Spearheading a relentless crusade for sanitation, Blue and his men patrolled the squalid streets of fast-growing San Francisco, examined gory black buboes, and dissected diseased rats that put the fate of the entire country at risk.In the tradition of Erik Larson and Steven Johnson, Randall spins a spellbinding account of Blue’s race to understand the disease and contain its spread—the only hope of saving San Francisco, and the nation, from a gruesome fate.

    People in this middle place have sustained traumatic brain injuries or are the victims of stroke or degenerative diseases, such as Alzheimer’s and Parkinson’s. Many are oblivious to the outside world, and their doctors believe they are incapable of thought. But a sizeable number are experiencing something different: intact minds adrift deep within damaged brains and bodies. Following Owen’s journey of exciting medical discovery, Into the Gray Zone asks some tough and terrifying questions, such as: What is life like for these patients? What can their families and friends do to help them? What are the ethical implications for religious organizations, politicians, the Right to Die movement, and even insurers? And perhaps most intriguing of all: in defining what a life worth living is, are we too concerned with the physical and not giving enough emphasis to the power of thought? What, truly, defines a satisfying life?

    The majority view is that life began with replicating molecules, the precursors of modern genes. The minority belief is that random populations of molecules evolved metabolic activities before exact replication existed and that natural selection drove the evolution of cells toward greater complexity for a long time without the benefit of genes. Dyson analyzes both of these theories with reference to recent important discoveries by geologists and chemists, aiming to stimulate new experiments that could help decide which theory is correct. This second edition covers the impact revolutionary discoveries such as the existence of ribozymes, enzymes made of RNA; the likelihood that many of the most ancient creatures are thermophilic, living in hot environments; and evidence of life in the most ancient of all terrestrial rocks in Greenland have had on our ideas about how life began. It is a clearly written, fascinating book that will appeal to anyone interested in the origins of life.

    Perry Baird was a rising medical star in the late 1920s and 1930s. Early in his career, ahead of his time, he grew fascinated with identifying the biochemical root of manic depression, just as he began to suffer from it himself. By the time the results of his groundbreaking experiments were published, Dr. Baird had been institutionalized multiple times, his medical license revoked, and his wife and daughters estranged. He later received a lobotomy and died from a consequent seizure, his research incomplete, his achievements unrecognized.Mimi Baird grew up never fully knowing this story, as her family went silent about the father who had been absent for most of her childhood. Decades later, a string of extraordinary coincidences led to the recovery of a manuscript which Dr. Baird had worked on throughout his brutal institutionalization, confinement, and escape. This remarkable document, reflecting periods of both manic exhilaration and clear-headed health, presents a startling portrait of a man who was a uniquely astute observer of his own condition, struggling with a disease for which there was no cure, racing against time to unlock the key to treatment before his illness became impossible to manage.Fifty years after being told her father would forever be “ill” and “away,” Mimi Baird set off on a quest to piece together the memoir and the man. In time her fingers became stained with the lead of the pencil he had used to write his manuscript, as she devoted herself to understanding who he was, why he disappeared, and what legacy she had inherited. The result of his extraordinary record and her journey to bring his name to light is He Wanted the Moon, an unforgettable testament to the reaches of the mind and the redeeming power of a determined heart.Soon to be a major motion picture, from Brad Pitt and Tony Kushner
