    In college, I ran against Kenyans, and wondered whether endurance genes might have traveled with them from East Africa. At the same time, I began to notice that a training group on my team could consist of five men who run next to one another, stride for stride, day after day, and nonetheless turn out five entirely different runners. How could this be?We all knew a star athlete in high school. The one who made it look so easy. He was the starting quarterback and shortstop; she was the all-state point guard and high-jumper. Naturals. Or were they?The debate is as old as physical competition. Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training?The truth is far messier than a simple dichotomy between nature and nurture. In the decade since the sequencing of the human genome, researchers have slowly begun to uncover how the relationship between biological endowments and a competitor’s training environment affects athleticism. Sports scientists have gradually entered the era of modern genetic research.In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle. He investigates the so-called 10,000-hour rule to uncover whether rigorous and consistent practice from a young age is the only route to athletic excellence.Along the way, Epstein dispels many of our perceptions about why top athletes excel. He shows why some skills that we assume are innate, like the bullet-fast reactions of a baseball or cricket batter, are not, and why other characteristics that we assume are entirely voluntary, like an athlete’s will to train, might in fact have important genetic components.This subject necessarily involves digging deep into sensitive topics like race and gender. Epstein explores controversial questions such as:Are black athletes genetically predetermined to dominate both sprinting and distance running, and are their abilities influenced by Africa’s geography?Are there genetic reasons to separate male and female athletes in competition?Should we test the genes of young children to determine if they are destined for stardom?Can genetic testing determine who is at risk of injury, brain damage, or even death on the field?Through on-the-ground reporting from below the equator and above the Arctic Circle, revealing conversations with leading scientists and Olympic champions, and interviews with athletes who have rare genetic mutations or physical traits, Epstein forces us to rethink the very nature of athleticism.

    In 1967, Dr. D.A. Henderson became director of a worldwide campaign to eliminate this disease from the face of the earth.This spellbinding book is Dr. Henderson’s personal story of how he led the World Health Organization’s campaign to eradicate smallpox—the only disease in history to have been deliberately eliminated. Some have called this feat "the greatest scientific and humanitarian achievement of the past century."In a lively, engrossing narrative, Dr. Henderson makes it clear that the gargantuan international effort involved more than straightforward mass vaccination. He and his staff had to cope with civil wars, floods, impassable roads, and refugees as well as formidable bureaucratic and cultural obstacles, shortages of local health personnel and meager budgets. Countries across the world joined in the effort; the United States and the Soviet Union worked together through the darkest cold war days; and professionals from more than 70 nations served as WHO field staff. On October 26, 1976, the last case of smallpox occurred. The disease that annually had killed two million people or more had been vanquished–and in just over ten years.The story did not end there. Dr. Henderson recounts in vivid detail the continuing struggle over whether to destroy the remaining virus in the two laboratories still that held it. Then came the startling discovery that the Soviet Union had been experimenting with smallpox virus as a biological weapon and producing it in large quantities. The threat of its possible use by a rogue nation or a terrorist has had to be taken seriously and Dr. Henderson has been a central figure in plans for coping with it.New methods for mass smallpox vaccination were so successful that he sought to expand the program of smallpox immunization to include polio, measles, whooping cough, diphtheria, and tetanus vaccines. That program now reaches more than four out of five children in the world and is eradicating poliomyelitis.This unique book is to be treasured—a personal and true story that proves that through cooperation and perseverance the most daunting of obstacles can be overcome.

    When temperatures drop below 56°F, tin crumbles into powder. Were the soldiers of the Grande Armée acutee fatally weakened by cold because the buttons of their uniforms fell apart? How different our world might be if tin did not disintegrate at low temperatures and the French had continued their eastward expansion! This fascinating book tells the stories of seventeen molecules that, like the tin of those buttons, greatly influenced the course of history. These molecules provided the impetus for early exploration and made possible the ensuing voyages of discovery. They resulted in grand feats of engineering and spurred advances in medicine; lie behind changes in gender roles, in law, and in the environment; and have determined what we today eat, drink, and wear. Showing how a change as small as the position of an atom can lead to enormous differences in the properties of a substance, the authors reveal the astonishing chemical connections among seemingly unrelated events. Napoleon's Buttons offers a novel way to understand how our contemporary world works and how our civilization has been shaped over time.

    This is what mother decided would be our best chance at survival. This was not an easy undertaking. To blend into the Polish community it was essential not to look Jewish; not to sound Jewish; to know a fair amount about Catholicism; and be able to think on your feet when unexpected events occurred. Above all one needed to be lucky. With counterfeit documents we changed our name and moved to Lublin, the site of Majdanek, the second largest concentration camp in Poland. At that time I was five years old and my brother was seven. We had to learn new names and to never reveal our past. No sooner we got settled that members of my father’s family descended on us seeking shelter. In a small, primitive house we hid up to eight members of my father’s family.

    

    Anthony Fauci is a hero. He is anything but. As director of the National Institute of Allergy and Infectious Diseases (NIAID), Dr. Anthony Fauci dispenses $6.1 billion in annual taxpayer-provided funding for scientific research, allowing him to dictate the subject, content, and outcome of scientific health research across the globe. Fauci uses the financial clout at his disposal to wield extraordinary influence over hospitals, universities, journals, and thousands of influential doctors and scientists—whose careers and institutions he has the power to ruin, advance, or reward. During more than a year of painstaking and meticulous research, Robert F. Kennedy Jr. unearthed a shocking story that obliterates media spin on Dr. Fauci . . . and that will alarm every American—Democrat or Republican—who cares about democracy, our Constitution, and the future of our children’s health. The Real Anthony Fauci reveals how “America’s Doctor” launched his career during the early AIDS crisis by partnering with pharmaceutical companies to sabotage safe and effective off-patent therapeutic treatments for AIDS. Fauci orchestrated fraudulent studies, and then pressured US Food and Drug Administration (FDA) regulators into approving a deadly chemotherapy treatment he had good reason to know was worthless against AIDS. Fauci repeatedly violated federal laws to allow his Pharma partners to use impoverished and dark-skinned children as lab rats in deadly experiments with toxic AIDS and cancer chemotherapies. In early 2000, Fauci shook hands with Bill Gates in the library of Gates’ $147 million Seattle mansion, cementing a partnership that would aim to control an increasingly profitable $60 billion global vaccine enterprise with unlimited growth potential. Through funding leverage and carefully cultivated personal relationships with heads of state and leading media and social media institutions, the Pharma-Fauci-Gates alliance exercises dominion over global health policy. The Real Anthony Fauci details how Fauci, Gates, and their cohorts use their control of media outlets, scientific journals, key government and quasi-governmental agencies, global intelligence agencies, and influential scientists and physicians to flood the public with fearful propaganda about COVID-19 virulence and pathogenesis, and to muzzle debate and ruthlessly censor dissent.

    The Tuskegee Study had nothing to do with treatment. Its purpose was to trace the spontaneous evolution of the disease in order to learn how syphilis affected black subjects.The men were not told they had syphilis; they were not warned about what the disease might do to them; and, with the exception of a smattering of medication during the first few months, they were not given health care. Instead of the powerful drugs they required, they were given aspirin for their aches and pains. Health officials systematically deceived the men into believing they were patients in a government study of “bad blood”, a catch-all phrase black sharecroppers used to describe a host of illnesses. At the end of this 40 year deathwatch, more than 100 men had died from syphilis or related complications.“Bad Blood” provides compelling answers to the question of how such a tragedy could have been allowed to occur. Tracing the evolution of medical ethics and the nature of decision making in bureaucracies, Jones attempted to show that the Tuskegee Study was not, in fact, an aberration, but a logical outgrowth of race relations and medical practice in the United States.Now, in this revised edition of “Bad Blood”, Jones traces the tragic consequences of the Tuskegee Study over the last decade. A new introduction explains why the Tuskegee Study has become a symbol of black oppression and a metaphor for medical neglect, inspiring a prize-winning play, a Nova special, and a motion picture. A new concluding chapter shows how the black community's wide-spread anger and distrust caused by the Tuskegee Study has hampered efforts by health officials to combat AIDS in the black community. “Bad Blood” was nominated for the Pulitzer Prize and was one of the “N.Y. Times” 12 best books of the year.

    Jason Fung forever changed the way we think about obesity with his best-selling book, The Obesity Code. Now he has set out to do the same for type 2 diabetes.Today, most doctors, dietitians, and even diabetes specialists consider type 2 diabetes to be a chronic and progressive disease—a life sentence with no possibility of parole. But the truth, as Dr. Fung reveals in this paradigm-shifting book, is that type 2 diabetes is reversible. Writing with clear, persuasive language, he explains why conventional treatments that rely on insulin or other blood-glucose-lowering drugs can actually exacerbate the problem, leading to significant weight gain and even heart disease. The only way to treat type 2 diabetes effectively, he argues, is proper dieting and intermittent fasting—not medication.

    is the first deep-dive investigation of a hazardous and illicit industry that has created a worldwide epidemic, ravaging communities and overwhelming and confounding government agencies that are challenged to combat it. "A whole new crop of chemicals is radically changing the recreational drug landscape," writes Ben Westhoff. "These are known as Novel Psychoactive Substances (NPS) and they include replacements for known drugs like heroin, cocaine, ecstasy, and marijuana. They are synthetic, made in a laboratory, and are much more potent than traditional drugs"--and all-too-often tragically lethal. Drugs like fentanyl, K2, and Spice--and those with arcane acronyms like 25i-NBOMe-- were all originally conceived in legitimate laboratories for proper scientific and medicinal purposes. Their formulas were then hijacked and manufactured by rogue chemists, largely in China, who change their molecular structures to stay ahead of the law, making the drugs' effects impossible to predict. Westhoff has infiltrated this shadowy world, becoming the first journalist to report from inside an illicit Chinese fentanyls lab and providing startling and original reporting on how China's vast chemical industry operates, and how the Chinese government subsidizes it. He tracks down the little-known scientists who invented these drugs and inadvertently killed thousands, as well as a mysterious drug baron who turned the law upside down in his home country of New Zealand. Poignantly, Westhoff chronicles the lives of addicted users and dealers, families of victims, law enforcement officers, and underground drug awareness organizers in the U.S. and Europe. Together they represent the shocking and riveting full anatomy of a calamity we are just beginning to understand. From its depths, as Westhoff relates, are emerging new strategies that may provide essential long-term solutions to the drug crisis that has affected so many.

    The effects of homeopathy don’t go away under rigorous scientific conditions. The laws of nature aren’t what they used to be. Thirty years on, no one has an explanation for a seemingly intelligent signal received from outer space. The US Department of Energy is re-examining cold fusion because the experimental evidence seems too solid to ignore. The placebo effect is put to work in medicine while doctors can’t agree whether it even exists.In an age when science is supposed to be king, scientists are beset by experimental results they simply can’t explain. But, if the past is anything to go by, these anomalies contain the seeds of future revolutions. While taking readers on an entertaining tour d’horizon of the strangest of scientific findings – involving everything from our lack of free will to Martian methane that offers new evidence of life on the planet – Michael Brooks argues that the things we don’t understand are the key to what we are about to discover.This mind-boggling but entirely accessible survey of the outer limits of human knowledge is based on a short article by Michael Brooks for New Scientist magazine. It became the sixth most circulated story on the internet in 2005, and provoked widespread comment and compliments (Google “13 things that do not make sense” to see).Michael Brooks has now dug deeply into those mysteries, with extraordinary results.

    Eyes wide open. I was standing at an open window, staring at the dizzying curve of Riverside Drive, five floors below. I’d stopped, somehow, poised, about to jump.Growing up the good girl in an Irish American family full of drinkers and terrible sleepers, Kathleen Frazier was twelve when her seemingly innocent sleepwalking turned dangerous. Over the next few years, she was a popular A+ student by day, the star of her high school musical. At night, she both longed for and dreaded sleep.Frazier moved to Manhattan in the 1980s, hoping for a life in the theater but getting a run of sleepwalking performances instead. Efforts to abate her malady with drinking failed miserably. She became promiscuous, looking for nighttime companionship. Could a bed partner save her from flinging herself down a flight of stairs or out an open window? Exhaustion stalked her, and rest and love were seemingly out of reach.This is the journey Frazier illuminates in her intimate memoir. While highlighting her quest to beat her sleep terrors and insomnia, this is ultimately a story of health, hope, and redemption.

    Jonathan Eig's masterful narrative revolves around four principal characters: the fiery feminist Margaret Sanger, who was a champion of birth control in her campaign for the rights of women but neglected her own children in pursuit of free love; the beautiful Katharine McCormick, who owed her fortune to her wealthy husband, the son of the founder of International Harvester and a schizophrenic; the visionary scientist Gregory Pincus, who was dismissed by Harvard in the 1930s as a result of his experimentation with in vitro fertilization but who, after he was approached by Sanger and McCormick, grew obsessed with the idea of inventing a drug that could stop ovulation; and the telegenic John Rock, a Catholic doctor from Boston who battled his own church to become an enormously effective advocate in the effort to win public approval for the drug that would be marketed by Searle as Enovid.Spanning the years from Sanger’s heady Greenwich Village days in the early twentieth century to trial tests in Puerto Rico in the 1950s to the cusp of the sexual revolution in the 1960s, this is a grand story of radical feminist politics, scientific ingenuity, establishment opposition, and, ultimately, a sea change in social attitudes. Brilliantly researched and briskly written, The Birth of the Pill is gripping social, cultural, and scientific history.

    Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways?Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.

    As gripping as CSI and as eye-opening as Mary Roach’s Stiff, Carney’s The Red Market sheds a blazing new light on the disturbing, billion-dollar business of trading in human body parts, bodies, and child trafficking, raising issues and exposing corruptions almost too bizarre and shocking to imagine.
