Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field’s most recent research.Changizi focuses on four “why” questions:1. Why do we see in color?2. Why do our eyes face forward?3. Why do we see illusions?4. Why does reading come so naturally to us?Why Do We See in Color?It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi’s research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it’s no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans.Why Do Our Eyes Face Forward?Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi’s research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we’re able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You’ll find that you’re able to look “through” it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren’t blocked by our noses, beaks, etc.Why Do We See Illusions?We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn’t catch a ball because the brain’s ability to process visual information isn’t fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past,” Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving” element into the future and, as a result, we don’t see what’s on the page, but what our brain thinks will be the case a fraction of a second into the future.Why Does Reading Come So Naturally to Us?We can read faster than we can hear, which is odd, considering that reading is relatively recent, and we’ve evolved to process speech for millions of years. Changizi’s research reveals that language has been carefully designed to tap in to elements of the visual processing center that have evolved for tens of millions of years. Visual signs of all languages are shaped like objects in nature, Changizi says, because we have evolved to see nature easily. “People have noticed letters in nature for some time, and there are artists who have a spent a lot of time photographing Latin letters in natural scenes or on butterfly wings,” Changizi says. “For example, if you look at an upper corner of the room you are in, you will see three contours meeting at a point, making a shape close to that of a ‘Y.’“ The Vision Revolution expands upon how our ancestors found the shapes of Latin letters and delves into how visual signs can have similar shapes even though their inspirations come from very different environments.In addition to these four areas, The Vision Revolution explores other phenomena such as cyclopses, peeking and many more you hadn’t even thought to wonder about. Changizi shows how deeply involved these evolutionary aspects of our vision are in why we see the way we do—and what the future holds for us.“…to understand how culture interacts with vision, one must understand not just the eye’s design, but the actual mechanisms we have evolved,” Changizi says, “for culture can tap in to both the designed responses of our brains and the unintended responses.”The Vision Revolution is a book that finally gives attention to what before has been largely neglected by other works on human vision—a book that looks at the “why.”

    Warren Andiman, an HIV/AIDS researcher who has been on the front lines battling infectious diseases for over forty years. In Animal Viruses and Humans: A Narrow Divide, Andiman traces the history of eight zoonotic viruses —deadly microbes that have made the leap directly from animals to human populations: Middle East Respiratory Syndrome (MERS), Swine influenza, Hantavirus, Monkeypox, Severe Acute Respiratory Syndrome (SARS), Rabies, Ebola, and Henipaviruses (Nipah and Hendra). He also illustrates the labor intensive and fascinating detective work that infectious disease specialists must do to uncover the source of an outbreak.Andiman also looks to the future, envisioning the effects on zoonoses (diseases caused by zoonotic viruses) of climate change, microenvironmental damage, population shifts, and globalization. He reveals the steps that we can, and must, take to stem the spread of animal viruses, explaining, “The zoonoses I've chosen to write about . . . are meant to describe only a small sample of what is already out there but, more menacingly, what is inevitably on its way, in forms we can only imagine.” Warren Andiman, MD is professor emeritus of pediatrics and epidemiology at the Yale Schools of Medicine and Public Health.

    Now comes a gripping account of the doctors and scientists fighting to protect us, an urgent wake-up call about the future of emerging viruses—from the #1 bestselling author of The Hot Zone, soon to be a National Geographic original miniseries.This time, Ebola started with a two-year-old child who likely had contact with a wild creature and whose entire family quickly fell ill and died. The ensuing global drama activated health professionals in North America, Europe, and Africa in a desperate race against time to contain the viral wildfire. By the end—as the virus mutated into its deadliest form, and spread farther and faster than ever before—30,000 people would be infected, and the dead would be spread across eight countries on three continents.In this taut and suspenseful medical drama, Richard Preston deeply chronicles the outbreak, in which we saw for the first time the specter of Ebola jumping continents, crossing the Atlantic, and infecting people in America. Rich in characters and conflict—physical, emotional, and ethical—Crisis in the Red Zone is an immersion in one of the great public health calamities of our time.Preston writes of doctors and nurses in the field putting their own lives on the line, of government bureaucrats and NGO administrators moving, often fitfully, to try to contain the outbreak, and of pharmaceutical companies racing to develop drugs to combat the virus. He also explores the charged ethical dilemma over who should and did receive the rare doses of an experimental treatment when they became available at the peak of the disaster. Crisis in the Red Zone makes clear that the outbreak of 2013–2014 is a harbinger of further, more severe outbreaks, and of emerging viruses heretofore unimagined—in any country, on any continent. In our ever more interconnected world, with roads and towns cut deep into the jungles of equatorial Africa, viruses both familiar and undiscovered are being unleashed into more densely populated areas than ever before.The more we discover about the virosphere, the more we realize its deadly potential. Crisis in the Red Zone is an exquisitely timely book, a stark warning of viral outbreaks to come.

    We see it, touch it, and live in it every day. It is a habitat for a mesmerizingly complex world of micro-organisms and physical functions that are vital to our health and our survival. It is also a waste removal plant, a warning system for underlying disease and a dynamic immune barrier to infection. One of the first things people see about us, skin is crucial to our sense of identity, providing us with social significance and psychological meaning. And yet our skin and the fascinating way it functions is largely unknown to us. In prose as lucid as his research underlying it is rigorous, blending in memorable stories from the past and from his own medical experience, Monty Lyman has written a revelatory book exploring our outer surface that will surprise and enlighten in equal measure. Through the lenses of science, sociology, and history--on topics as diverse as the mechanics and magic of touch (how much goes on in the simple act of taking keys out of a pocket and unlocking a door is astounding), the close connection between the skin and the gut, what happens instantly when one gets a paper cut, and how a midnight snack can lead to sunburn--Lyman leads us on a journey across our most underrated and unexplored organ and reveals how our skin is far stranger, more wondrous, and more complex than we have ever imagined.

    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.

    Entering a room with stainless-steel tables topped by corpses in body bags is shocking no matter how long you've prepared yourself, but a strange thing happened when Montross met her cadaver. Instead of being disgusted by her, she was utterly intrigued-intrigued by the person the woman once was, humbled by the sacrifice she had made in donating her body to science, fascinated by the strange, unsettling beauty of the human form. They called her Eve. This is the story of Montross and Eve-the student and the subject-and the surprising relationship that grew between them. Body of Work is a mesmerizing, rarely seen glimpse into the day-to-day life of a medical student-yet one that follows naturally in the footsteps of recent highly successful literary renderings of the mysteries of medicine such as Atul Gawande's Complications: A Surgeon's Notes on an Imperfect Science. Christine Montross was a poet long before she became a doctor and brings an uncommon perspective to the emotional difficulty of the first year of medical school-the dispiriting task of remaining clinical and detached while in the anatomy lab and the struggle with the line you've crossed by violating another's body once you leave it. Montross was so affected by her experience with Eve that she undertook to learn more about the history of cadavers and the study of anatomy. She visited an autopsy lab in Ireland and the University of Padua in Italy where Vesalius, a forefather of anatomy, once studied; she learned about body snatchers and grave-robbers and anatomists who practiced their work on live criminals. Her disturbing, often entertaining anecdotes enrich this exquisitely crafted memoir, endowing an eerie beauty to the world of a doctor-in-training. Body of Work is an unforgettable examination of the mysteries of the human body and a remarkable look at our relationship with both the living and the dead.

    A school cafeteria lunch is infected with a drug-resistant strain of E. coli.... Thousands in a bustling shopping mall inhale a lethal mist of smallpox, turning each individual into a highly infectious agent of suffering and death....Dr. Michael Osterholm knows all too well the horrifying scenarios he describes. In this eye-opening account, the nation’s leading expert on bioterrorism sounds a wake-up call to the terrifying threat of biological attack — and America’s startling lack of preparedness. He demonstrates the havoc these silent killers can wreak, exposes the startling ease with which they can be deployed, and asks probing questions about America’s ability to respond to such attacks. Are most doctors and emergency rooms able to diagnose correctly and treat anthrax, smallpox, and other potential tools in the bioterrorist’s arsenal? Is the government developing the appropriate vaccines and treatments? The answers are here in riveting detail — what America has and hasn’t done to prevent the coming bioterrorist catastrophe. Impeccably researched, grippingly told, Living Terrors presents the unsettling truth about the magnitude of the threat. And more important, it presents the ultimate insider’s prescription for change: what we must do as a nation to secure our freedom, our future, our lives.

    The threat of the disease kept ships close to home and doomed those vessels that ventured too far from port. The willful ignorance of the royal medical elite, who endorsed ludicrous medical theories based on speculative research while ignoring the life-saving properties of citrus fruit, cost tens of thousands of lives and altered the course of many battles at sea. The cure for scurvy ranks among the greatest of human accomplishments, yet its impact on history has, until now, been largely ignored.From the earliest recorded appearance of the disease in the sixteenth century, to the eighteenth century, where a man had only half a chance of surviving the scourge, to the early nineteenth century, when the British conquered scurvy and successfully blockaded the French and defeated Napoleon, Scurvy is a medical detective story for the ages, the fascinating true story of how James Lind (the surgeon), James Cook (the mariner), and Gilbert Blane (the gentleman) worked separately to eliminate the dreaded affliction.Scurvy is an evocative journey back to the era of wooden ships and sails, when the disease infiltrated every aspect of seafaring life: press gangs "recruit" mariners on the way home from a late night at the pub; a terrible voyage in search of riches ends with a hobbled fleet and half the crew heaved overboard; Cook majestically travels the South Seas but suffers an unimaginable fate. Brimming with tales of ships, sailors, and baffling bureaucracy, Scurvy is a rare mix of compelling history and classic adventure story.

    From the conquest of Mexico by smallpox as much as by the Spanish, to the bubonic plague in China, to the typhoid epidemic in Europe, the history of disease is the history of humankind. With the identification of AIDS in the early 1980s, another chapter has been added to this chronicle of events, which William McNeill explores in his new introduction to this updated editon.Thought-provoking, well-researched, and compulsively readable, Plagues and Peoples is that rare book that is as fascinating as it is scholarly, as intriguing as it is enlightening. "A brilliantly conceptualized and challenging achievement" (Kirkus Reviews), it is essential reading, offering a new perspective on human history.

    In that short time, many doctors decide on the likely diagnosis and best treatment. Often, decisions made this way are correct, but at crucial moments they can also be wrong -- with catastrophic consequences. In this myth-shattering book, Jerome Groopman pinpoints the forces and thought processes behind the decisions doctors make. Groopman explores why doctors err and shows when and how they can -- with our help -- avoid snap judgments, embrace uncertainty, communicate effectively, and deploy other skills that can profoundly impact our health. This book is the first to describe in detail the warning signs of erroneous medical thinking and reveal how new technologies may actually hinder accurate diagnoses. How Doctors Think offers direct, intelligent questions patients can ask their doctors to help them get back on track.Groopman draws on a wealth of research, extensive interviews with some of the country’s best doctors, and his own experiences as a doctor and as a patient. He has learned many of the lessons in this book the hard way, from his own mistakes and from errors his doctors made in treating his own debilitating medical problems.How Doctors Think reveals a profound new view of twenty-first-century medical practice, giving doctors and patients the vital information they need to make better judgments together.

    David B. Agus shared what he has learned from his work as a pioneering cancer doctor, revealing the innovative steps he takes to prolong the lives of not only cancer patients, but all those who want to enjoy a vigorous, lengthy life. Now Dr. Agus has turned his research into a practical and concise illustrated handbook for everyday living. A Short Guide to a Long Life is divided into three sections (What to Do, What to Avoid, and Doctor's Orders) that provide the definitive answers to many common and not-so-common questions: Who should take a baby aspirin daily? Are flu shots safe? What constitutes "healthy" foods? Are airport scanners hazardous? Dr. Agus believes optimal health begins with our daily routines. His book will help you develop new patterns of personal health care, using inexpensive and widely available tools that are based on the latest and most reliable science.

    It gives your body its shape and the ability to move. It grows and changes with you, an undeniable document of who you are and how you lived. Arguably, no other part of the human anatomy has such rich scientific and cultural significance, both brimming with life and a potent symbol of death.In this delightful natural and cultural history of bone, Brian Switek explains where our skeletons came from, what they do inside us, and what others can learn about us when these artifacts of mineral and protein are all we've left behind.Bone is as embedded in our culture as it is in our bodies. Our species has made instruments and jewelry from bone, treated the dead like collectors' items, put our faith in skull bumps as guides to human behavior, and arranged skeletons into macabre tributes to the afterlife. Switek makes a compelling case for getting better acquainted with our skeletons, in all their surprising roles. Bridging the worlds of paleontology, anthropology, medicine, and forensics, Skeleton Keys illuminates the complex life of bones inside our bodies and out.

    Angier takes readers on a mesmerizing tour of female anatomy and physiology that explores everything from organs to orgasm, and delves into topics such as exercise, menopause, and the mysterious properties of breast milk.A self-proclaimed "scientific fantasia of womanhood." Woman ultimately challenges widely accepted Darwinian-based gender stereotypes. Angier shows how cultural biases have influenced research in evolutionary psychology (the study of the biological bases of behavior) and consequently led to dubious conclusions about "female nature." such as the idea that women are innately monogamous while men are natural philanderers.But Angier doesn't just point fingers; she offers optimistic alternatives and transcends feminist polemics with an enlightened subversiveness that makes for a joyful, fresh vision of womanhood. Woman is a seminal work that will endure as an essential read for anyone intersted in how biology affects who we are as women, as men, and as human beings.

    We get cancer because we can't avoid it—it's a bug in the system of life itself.Cancer exists in nearly every animal and has afflicted humans as long as our species has walked the earth. In Rebel Cell: Cancer, Evolution, and the New Science of Life's Oldest Betrayal, Kat Arney reveals the secrets of our most formidable medical enemy, most notably the fact that it isn't so much a foreign invader as a double agent: cancer is hardwired into the fundamental processes of life. New evidence shows that this disease is the result of the same evolutionary changes that allowed us to thrive. Evolution helped us outsmart our environment, and it helps cancer outsmart its environment as well—alas, that environment is us.Explaining why "everything we know about cancer is wrong," Arney, a geneticist and award-winning science writer, guides readers with her trademark wit and clarity through the latest research into the cellular mavericks that rebel against the rigid biological "society" of the body and make a leap towards anarchy.We need to be a lot smarter to defeat such a wily foe—smarter even than Darwin himself. In this new world, where we know that every cancer is unique and can evolve its way out of trouble, the old models of treatment have reached their limits. But we are starting to decipher cancer's secret evolutionary playbook, mapping the landscapes in which these rogue cells survive, thrive, or die, and using this knowledge to predict and confound cancer's next move.Rebel Cell is a story about life and death, hope and hubris, nature and nurture. It's about a new way of thinking about what this disease really is and the role it plays in human life. Above all, it's a story about where cancer came from, where it's going, and how we can stop it.

    The germ revolution came after two decades of scientific virtuosity, outstanding feats of intellectual courage and bitter personal rivalries, doctors at last recognised that infectious diseases are caused by mircoscopic organisms.
