We know they make your eyes blue, your hair curly or your nose straight. The media tells us that our genes control the risk of cancer, heart disease, alcoholism or Alzheimer's. The cost of DNA sequencing has plummeted from billions of pounds to a few hundred, and gene-based advances in medicine hold huge promise.So we've all heard of genes, but how do they actually work?According to legend, Ernest Hemingway was once given a six-toed cat by an old sea captain, and her distinctive descendants still roam the writer's Florida estate today. Scientists now know that the fault driving this profusion of digits lies in a tiny genetic control switch, miles away (in molecular terms) from the gene that 'makes' toes. And it's the same mistake that gives rise to multi-toed humans too.There are 2.2 metres of DNA inside every one of your cells, encoding roughly 20,000 genes. These are the 'recipes' that tell our cells how to make the building blocks of life, along with myriad control switches ensuring they're turned on and off at the right time and in the right place. But rather than a static string of genetic code, this is a dynamic, writhing biological library. And figuring out how it all works – how your genes make you, you – is a major challenge for researchers around the world.Drawing on stories ranging from six-toed cats and stickleback hips to wobbly worms and zombie genes, geneticist Kat Arney explores the how our genes work, creating a companion reader to the book of life itself.

    Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress.As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear--and the ones that plague us now--are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animal's does, but we do not resolve conflict in the same way--through fighting or fleeing. Over time, this activation of a stress response makes us sick.

    Why on earth has the entirely land-loving Eastern mole been named "Scalopus Aquaticus" or the Oxford ragwort been called "Senecio Squalidus" (translation: "dirty old man")? What were naturalists thinking when they called a beetle "Agra Katewinsletae," a genus of fish "Batman," and a trilobite "Han Solo"? Why is zoology replete with names such as "Chloris Chloris Chloris" (the greenfinch) and "Gorilla Gorilla Gorilla" (a species of, well, gorilla)? The Naming of the Shrew will unveil these mysteries, exploring the history, celebrating their poetic nature, and revealing how naturalists sometimes get things so terribly wrong. With wonderfully witty style and captivating narrative, this book will make you see Latin names in a whole new light.

    Because of this balance, the Seventh Edition of Microbiology is appropriate for microbiology majors and mixed majors courses. The new authors have focused on readability, artwork, and the integration of several key themes (including evolution, ecology and diversity) throughout the text, making an already superior text even better.

    In this extraordinary feat of nature writing, we meet ants who harvest crops, raise insects as livestock, build roadways and bridges, embark on nuptial flights, and make war.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    An indispensable tool for naturalists traveling to Africa, this new edition has been revised to acknowledge the enthusiasm to those watching these magnificent animals at zoos and wildlife parks, and on film.The Safari Companion enables readers to recognize and interpret visible behavioral activities, such as courtship rituals, territorial marking, aggression, and care of young. Each account of over 80 species includes a behavioral table in which the unique actions of the hoofed mammals, carnivores, and primates are described for easy reference. In addition, useful maps show the major national boundaries, vegetation zones, and game parks relevant to the guide. The book includes an extensive glossary, as well as tips on wildlife photography, a list of organizations working to protect African wildlife, and advice on where and when to see the animals.

    As miraculous a feat of nature as the snowflakes has been, have we ever been truly able to appreciate this infinitesimal wonder in all its crystalline glory? Art of the Snowflake, as much a work of art as a testament to science, reveals how one of the snowflake's most inspired photographers came to such intimate knowledge of his craft and its fleeting focus. Beautiful pictures illustrate Kenneth Libbrecht's story of the microphotography of snow crystals, from the pioneering work of Wilson Bentley in the 1890s right up to Ken's own innovations in our age of digital images. A breathtaking look at the works of art that melt in an instant, this is a book to flip through and savor, season after season.

    There are simply too many birds in them. This book introduces the reader to Britain's most obvious birds. But it does more than that: it also explains them. It explains the way that different birds do different things, eat different food, sing different songs and live different lives, and it explains why they are different. If you are a would-be birdwatcher but don't know where to start, A Bad Field Guide is for you. It will help you understand birdwatching: but far more important, it will help you begin to understand birds. Robin...But have you ever wondered what a red breast means to a robin? A red breast is not just the way a human can recognise a robin when it comes a-calling, when it sits on a spade or a Christmas card. The red breast is not just a bit of chance colouration. No: the red breast is the core of the robin's being. The red breast is the love, the honour and the glory of a robin. Have you noticed that a robin positively flaunts it? It is as if he is telling the world: for God's sake, I'm a robin!

    Fast Tract Digestion Heartburn is the first book to define and address the real cause of acid reflux. Acid reflux occurs as a result of digestive malabsorption of five difficult-to-digest carbohydrates. It leads to the overgrowth of gas-producing bacteria in the small intestine and the gas pressure drives acid reflux. Dropping a Mentos into a bottle of Coke is the perfect illustration of this phenomenon. Unfortunately, PPI drugs do not address the real cause, but also cause serious side effects including vitamin and mineral malabsorption, bone fractures, pneumonia, low blood magnesium levels, bacterial overgrowth, C diff infection and pneumonia as explained in the book.Fast Tract Digestion Heartburn offers science-based food choices and recipes (Fast Tract Diet) to limit the five difficult-to-digest carbohydrates, so that you can feel relief within a few days Also, it enables you to self-manage all of the symptoms of acid reflux going forward. The Fast Tract Diet is based on a scientific formula called Fermentation Potential (FP). FP is the key measure regardless of the carbohydrate count. Limiting foods with high FP will help control the overgrowth of bacteria in the small intestine and, as a result, acid reflux. The Fast Tract Diet was clinically tested on reflux sufferers in the Boston area. The results were overwhelming and proved the effectiveness of the diet as an alternative to proton pump inhibitor drugs.

    He would return in September. For the next ten weeks my survival would depend on foraging, hunting and fishing on an island I would share with 1,600 brown bears. This is my story of hunger and solitude, salmon fishing and stormy seas, torrential rains and mountain sunsets, giant halibut and deer hunting, campfires and killer whales. Illustrated with nearly fifty photos and a map.
