     With rivalries, reversals, and a race against time, the struggle to eradicate polio is one of the great tales of modern history. It begins with the birth of Jonas Salk, shortly before one of the worst polio epidemics in United States history. At the time, the disease was a terrifying enigma: striking from out of nowhere, it afflicted tens of thousands of children in this country each year and left them-literally overnight-paralyzed, and sometimes at death's door. Salk was in medical school just as a president crippled by the disease, Franklin D. Roosevelt, was taking office-and providing the impetus to the drive for studies on polio. By the early 1950s, Salk had already helped create an influenza vaccine, and was hot on the trail of the polio virus. He was nearly thwarted, though, by the politics of medicine and by a rival researcher eager to discredit his proposed solution. Meanwhile, in 1952, polio was spreading in record numbers, with 57,000 cases in the United States that summer alone. In early 1954, Salk was weighing the possibility of trials of a not-yet-perfected vaccine against-as the summer approached-the prospect of thousands more children being struck down by the disease. The results of the history-making trials were announced at a press conference on April 12, 1955: "The vaccine works." The room-and an entire nation-erupted in cheers for this singular medical achievement. Salk became a cultural hero and icon for a whole generation. Now, at the fiftieth anniversary of the first national vaccination program-and as humanity is tantalizingly close to eradicating polio worldwide-comes this unforgettable chronicle. Salk's work was an unparalleled achievement-and it makes for a magnificent read.

    Written by Blaine T. Bettinger, PhD, JD, and Debbie Parker Wayne, CG, CGL, the book provides family historians and genealogists who have just begun to explore genetic genealogy practical, easy to understand information that they can apply to their research. As Wayne notes in her blog, Deb’s "Delvings in Genealogy," “DNA can seem complex to many of us, but this book will guide you and help build your knowledge level one step at a time.” At their own pace, readers learn the basic concepts of genetic genealogy. They then build on that knowledge as they study the testing, analysis, and application of YDNA, X-DNA, mitochondrial DNA (mtDNA), and autosomal DNA (atDNA) to reach and support genealogical conclusions. Each chapter includes exercises with answer keys for hands-on practice. Blaine Bettinger is an intellectual property attorney in Syracuse, New York. The author of The Genetic Genealogist blog, he is a genealogy educator, a trustee of the New York Genealogical and Biographical Society, and organizer of the Shared cM Project, a crowdsourced project examining the associations between genetic data and genealogical relationships. Debbie Parker Wayne is a professional genealogist who has conducted research for individuals as well as for the PBS series “Finding Your Roots” with Henry Louis Gates Jr. and other television shows. She is an award-winning author, the coordinator for genetic genealogy institute courses, and the DNA Project Chair for the Texas State Genealogical Society.

    Its job is to protect us from cancer. This gene--known simply as p53--constantly scans our cells to ensure that when they grow and divide as part of the routine maintenance of our bodies, they do so without mishap. If a cell makes a mistake in copying its DNA during the process of division, p53 stops it in its tracks, sending in the repair team before allowing the cell to carry on dividing. If the mistake is irreparable and the rogue cell threatens to grow out of control (as happens in cancer), p53 commands the cell to commit suicide. Cancer cannot develop unless p53 itself is damaged or handicapped by some other fault in the system. Not surprisingly, p53 is the most studied single gene in history. p53: The Gene that Cracked the Cancer Code tells the story of the discovery of the gene and of medical science's mission to unravel its mysteries and get to the heart of what happens in our cells when they turn cancerous. Through the personal accounts of key researchers, the book reveals the excitement of the hunt for new cures--the hype, the enthusiasm, the lost opportunities, the blind alleys and the thrilling breakthroughs. As the long-anticipated revolution in cancer treatment tailored to each individual patient's symptoms starts to take off at last, p53 is at the cutting edge. This is a timely tale of scientific discovery and advances in our understanding of a disease that still affects more than one in three of us at some point in our lives.

    In this riveting investigative narrative, McKenna dives deep into the world of modern agriculture by way of chicken: from the farm where it's raised directly to your dinner table. Consumed more than any other meat in the United States, chicken is emblematic of today's mass food-processing practices and their profound influence on our lives and health. Tracing its meteoric rise from scarce treat to ubiquitous global commodity, McKenna reveals the astounding role of antibiotics in industrial farming, documenting how and why "wonder drugs" revolutionized the way the world eats--and not necessarily for the better. Rich with scientific, historical, and cultural insights, this spellbinding cautionary tale shines a light on one of America's favorite foods--and shows us the way to safer, healthier eating for ourselves and our children.

    THE NEW YORK TIMES BESTSELLERUnlock the secret to extraordinary health by reducing high uric acid levels—the hidden risk you didn't know you had—by the author of Grain Brain and Brain Wash.What do obesity, insulin resistance, diabetes, fatty liver disease, hypertension, cardiovascular disease, stroke, neurological disorders, and premature death have in common? All can be stoked by high uric acid levels. Our most respected scientific literature is bursting with evidence that elevated uric acid levels lie at the root of many pervasive health conditions, but mainstream medicine for the most part remains unaware of this connection. This is especially alarming because a large number of Americans don’t know they are suffering from increased levels, putting them at risk for developing or exacerbating potentially life-threatening illnesses. Offering an engaging blend of science and practical advice, Drop Acid exposes the deadly truth about uric acid and teaches invaluable strategies to manage its levels, including how to:Reduce fructose and foods high in “purines” through simple dietary edits Lower uric acid levels through natural hacks like consuming tart cherries, vitamin C, quercetin, and coffeeIdentify common pharmaceuticals that threaten to increase uric acidImplement lifestyle interventions, like restorative sleep and exerciseEasily test your uric acid levels at home—a test routinely performed in your doctor’s office during regular check-ups but typically ignoredFeaturing the groundbreaking “LUV” (Lower Uric Values) diet, 35 delicious recipes, self-assessment quizzes, and a 21-day program for dropping levels, Drop Acid empowers readers with the information they need to address this hidden danger and live longer, leaner, and healthier lives.

    Lavishly illustrated with over sixty original artworks, All Yesterdays aims to challenge our notions of how prehistoric animals looked and behaved. As a critical exploration of palaeontological art, All Yesterdays asks questions about what is probable, what is possible, and what is commonly ignored.Written by palaeozoologist Darren Naish, and palaeontological artists John Conway and C.M. Kosemen, All Yesterdays is scientifically rigorous and artistically imaginative in its approach to fossils of the past - and those of the future.

    Literate and authoritative--.Marvelously exciting." --The New York Times Book ReviewJonathan Weiner, winner of the Pulitzer Prize for The Beak of the Finch, brings his brilliant reporting skills to the story of Seymour Benzer, the Brooklyn-born maverick scientist whose study of genetics and experiments with fruit fly genes has helped revolutionize or knowledge of the connections between DNA and behavior both animal and human.How much of our fate is decided before we are born?  Which of our characteristics is inscribed in our DNA? Weiner brings us into Benzer's Fly Rooms at the California Institute of Technology, where Benzer, and his asssociates are in the process of finding answers, often astonishing ones, to these questions. Part biography, part thrilling scientific detective story, Time, Love, Memory forcefully demonstrates how Benzer's studies are changing our world view--and even our lives.

    But by itself, DNA is just an inert blueprint for life. It is the ribosome--an enormous molecular machine made up of a million atoms--that makes DNA come to life, turning our genetic code into proteins and therefore into us. Gene Machine is an insider account of the race for the structure of the ribosome, a fundamental discovery that both advances our knowledge of all life and could lead to the development of better antibiotics against life-threatening diseases. But this is also a human story of Ramakrishnan's unlikely journey, from his first fumbling experiments in a biology lab to being the dark horse in a fierce competition with some of the world's best scientists. In the end, Gene Machine is a frank insider's account of the pursuit of high-stakes science.

    It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.Smil takes readers from bacterial invasions through animal metabolisms to megacities and the global economy. He begins with organisms whose mature sizes range from microscopic to enormous, looking at disease-causing microbes, the cultivation of staple crops, and human growth from infancy to adulthood. He examines the growth of energy conversions and man-made objects that enable economic activities—developments that have been essential to civilization. Finally, he looks at growth in complex systems, beginning with the growth of human populations and proceeding to the growth of cities. He considers the challenges of tracing the growth of empires and civilizations, explaining that we can chart the growth of organisms across individual and evolutionary time, but that the progress of societies and economies, not so linear, encompasses both decline and renewal. The trajectory of modern civilization, driven by competing imperatives of material growth and biospheric limits, Smil tells us, remains uncertain.

    In this book you will see how commonly performed operations can be found to be useless or even harmful when properly evaluated. That these claims come from an experienced, practicing orthopedic surgeon who performs many of these operations himself, makes the unsettling argument particularly compelling. Of course no surgeon is recommending invasive surgery in bad faith, but Ian Harris argues that the evidence for the success for many common operations, including knee arthroscopies, back fusion or cardiac stenting, become current accepted practice without full examination of the evidence.

    Fuzzy sonograms and doctor's explanations can provide basic information, but through Alexander Tsiaras' remarkable achievements in medical imaging technology, parents can see, for the first time, the awe-inspiring process of a new life unfolding, in stunning, vivid detail.The milestones of pregnancy which before could only be described can now be witnessed: the heart's first beats; the appearance of color in the eye; the emergence of toes and teeth; the brain and nervous system directing development; the first movement of tiny legs and arms; the first indications of gender; the wondrous symbiosis of mother and child; the symphony of the body's systems coming into being and working in concert. The book tracks the development of a baby from the moment of conception, through the explosively complex early stages of development and the amazing stages of growth as the baby is nurtured by the mother, ending with the joy of birth.All this is made possible by revolutions in two sciences. As biologists have decoded the molecular basis of life, computer scientists have developed non-invasive, three-dimensional techniques for visualizing the body. Alexander Tsiaras has been a pioneer in merging these explorations and discoveries. He has created a virtual camera studio that enables him to view a human body or any part of it individually, scan it, enlarge it, rotate it, adjust its transparency so that we can view inside a living being, and light it from any angle. The result is an ability to illuminate the unseen elements that make us who we are, and the miraculous images in From Conception to Birth.

    Drugs, transplants, and surgery don’t work for 90 percent of our aches and pains and, while we are grateful for life-saving developments, we know that most come with risks that we ignore at our peril.Long hailed as one of the founding fathers of mind-body medicine, Larry Dossey directs our attention to simple sources of healing that have been available for centuries—treasures often hidden in plain sight—from the power of optimism and of tears to speed recovery to the surprising usefulness of dirt and bugs in curing disease and infection to the benefits of doing nothing.Exploring the medical research that validates these simple remedies, Dossey encourages us to align ourselves with the wisdom of nature and allow true healing to take place. The Extraordinary Healing Power of Ordinary Things can transform our view of what health is all about, whether our concern is cancer or the common cold.From the Hardcover edition.
