In California, the family camps in the brutally hot Mojave, where MacDonald hopes to see a rare desert tortoise. And in Churchill, Manitoba, he seeks out the dwindling polar bears—and meets them at a closer proximity than he had imagined.Along the way, MacDonald offers fascinating details about the natural history of the endangered species he seeks, as well as threats like overpopulation, commercial fishing, and climate change that are driving them towards extinction.

    Over the next two weeks, the fire he set would consume 75,000 acres of forest and 144 buildings. More than one thousand firefighters would rally to extinguish the blaze, at a cost of 11 million dollars. Gunflint Burning is a comprehensive account of the dramatic events around the Ham Lake fire, one of the largest wildfires in Minnesota history. Cary J. Griffith describes what happened in the minutes, hours, and days after Posniak struck that fateful match—from the first hint of danger to the ensuing race to flee the fire or defend imperiled property to the incredible efforts of firefighters and residents battling a blaze that lit up the Gunflint Trail like the fuse to a powder keg.We meet locals faced with losing everything: the sheriff and his deputy tasked with getting everyone out alive; tourists caught unawares; men and women using every piece of equipment and modern firefighting technique against impossibly high winds and dry conditions to suppress a wildfire as it grew to historic proportions; and, finally, Stephen Posniak, who in the aftermath tragically took his own life—the fire’s only fatality.In sharp detail, Gunflint Burning describes the key events of the Ham Lake fire as they unfold, providing readers with a sense of being on the front lines of an epic struggle that was at times heroic, tragic, and sublime.

    However, once their predictions were compared to the results of experiments in the real world, it became clear that the principles of classical physics and mechanics were far from capable of explaining phenomena on the atomic scale. With this realization came the advent of quantum physics, one of the most important intellectual movements in human history. Today, quantum physics is everywhere: it explains how our computers work, how lasers transmit information across the Internet, and allows scientists to predict accurately the behavior of nearly every particle in nature. Its application continues to be fundamental in the investigation of the most expansive questions related to our world and the universe.However, while the field and principles of quantum physics are known to have nearly limitless applications, the fundamental reasons why this is the case are far less understood. In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved. From applications like data encryption and quantum computing to principles and concepts like "quantum nonlocality" and Heisenberg's uncertainty principle, Quantum Physics: What Everyone Needs to Know is a wide-reaching introduction to a nearly ubiquitous scientific topic.

    With this revealing narrative, she takes readers into the heart of an epic firefight, telling the stories of fire managers and air tanker pilots trying to combat a catastrophe bigger than they had ever imagined, and recounting both survivors’ and victims’ desperate efforts to escape flames moving faster than fire engines could drive. And she tells the story of the hapless hunter who got lost in the backcountry, with little water and no cell phone or GPS device, and started a signal fire that caused the calamity.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    In the late 1970s, while working at Marineland in California, Alexandra pioneered the recording of orca sounds by dropping a hydrophone into the tank of two killer whales. She recorded the varied language of mating, childbirth, and even grief after the birth of a stillborn calf. At the same time she made the startling observation that the whales were inventing wonderful synchronized movements, a behavior that was soon recognized as a defining characteristic of orca society. In 1984, Alexandra moved to a remote bay in British Columbia to continue her research with wild orcas. Her recordings of the whales have led her to a deeper understanding of the mystery of whale echolocation, the vocal communication that enables the mammals to find their way in the dark sea. A fascinating study of the profound communion between humans and whales, this book will open your eyes anew to the wonders of the natural world.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    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.

     Few people know much about stem cell research beyond the ethical questions raised by using embryos. But in the last decade, stem cell research has made huge advances toward eliminating some of our most intractable diseases. Now this sweeping and accessible book introduces us to this cutting-edge science that will revolutionize medicine and change the way we think about and treat disease. Alice Park takes us from stem cell's controversial beginnings to the recent electrifying promise of being able to create the versatile cells without using embryos at all. She shows us how stem cells give researchers an unprecedented ability to study disease while giving patients the promise of replacing diseased cells with healthy new ones. And she profiles the scientists and leaders-many with their own compelling stories-who have fueled the quest and will continue to shape the field in years to come.

    We all have one, but most of us will never see one. The heart surgeon now has that privilege but, for centuries, the heart was out of reach even for surgeons. So when a surgeon nowadays opens up a ribcage and mends a heart, it remains something of a miracle, even if, to some, it is merely plumbing. As with plumbers, the quality of surgeons’ work varies. As with plumbers, surgeons’ opinion of their own prowess and their own attitude to risk are not always reliable. Measurement is key. We’ve had a century of effective evidence-based medicine. We’ve had barely a decade of thorough monitoring of clinical outcomes. Thanks to the ground-breaking risk modelling of pioneering surgeons like Samer Nashef, we at last know how to judge whether an operation is in a patient’s best interest, which hospital and surgeon would be best for that operation, when it might best be performed and what the exact level of risk is. We have at last made what is important in surgery measurable. But how should surgeons, and their patients, use these newfound insights? Ever since his days as a medical student, Samer Nashef has challenged the medical profession to be more open and more accurate about the success of surgical procedures, for the sake of the patients. In The Naked Surgeon, he unclothes his own profession to demonstrate to his reader (and prospective patient) many revelations, such as the paradox at the heart of the cardiac surgeon’s craft: the more an operation is likely to kill you, the better it is for you. And he does so with absolute clarity, fluency and not a little wit.

    This volume contains over 1250 photographs of mushrooms and fungi, often showing the specimens in various stages of growth, and including all the latest botanical and common names as well as current ecological information on endangered species.

    I teach my children to be proud too. Because being a traveller means everything to me. It's not just a label, it goes much deeper. It's an identity that is burned into my heart.Paddy Doherty loves his life as an Irish traveler, but as a child he felt like an outsider. He was different from his siblings. On the rare occasions he went to school, he was bullied. And beyond the gates of the camp he found nothing but hostility. Slowly, Paddy's hurt turned into anger and by the age of 11 he had started out on an illustrious career as a bare-knuckle boxer. This earned him a position as one of the most well-respected (and feared) men in the traveling community. Yet while he won countless brutal fights in the ring, the real battles he faced were very much outside. In this deeply honest autobiography, he tells of how he has loved and lost five children, and plummeted to seven stone while battling depression, drink, and drugs. He describes how it feels to be shot point-blank in the head and the lengths he'll go to to protect his people. Told with all the warmth and humor he is famed for, Paddy's rich and colorful story is one that will stay with you for a long time to come.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    The full sweep of wonders-from pristine coral reefs to the Gettysburg battlefield to glaciers and all the glorious diversity in between-offers a breathtaking tour of the very best of America's national treasures.
