In this edition, each chapter presents the topic clearly and distinctly. Detailed, high-level scientific data and terminology are not included because the author believes that true knowledge consists of working concepts rather than technical facility.

    Weed. Bud. Whatever you choose to call it, it’s been a health aid, comfort, and life-enhancer for humankind for more than three thousand years. But while cannabis is used by hundreds of millions of people around the world, more than a century of prohibition has resulted in confusion about its status: Is it healthy? Is it medicinal? Will it make you crazy?In this fun, illuminating book, cannabis journalist Amanda Siebert delves deep into the latest research to separate marijuana fact from fiction, revealing ten evidence-based ways this potent little plant can improve your life. She speaks with some of the world’s top researchers, medical professionals, and consultants to answer questions such as: Can cannabis help you get a full night’s sleep? Does it aid in exercise and weight loss? Can it really cure cancer? She also offers practical advice for enjoying its benefits, including easy-to-follow, step-by-step instructions for consumption and dosage, as well as examples of real people who have used this drug to enhance their lives. Cannabis, it turns out, could be life-changing: it can enrich any diet, slow down aging, and even spice things up in the bedroom.

    Murderous Contagion tells the compelling and at times unbearably moving story of the devastating impact of diseases on humankind - from the Black Death of the 14th century to the Spanish flu of 1918-19 and the AIDS epidemic of the modern era. In this book Mary Dobson also relates the endeavours of physicians and scientists to understand and identify the causes of diseases and find ways of preventing them. This is a timely and revelatory work of popular history by a writer whose knowledge of, and enthusiasm for, her subject shines through her every word.

    To top it he had speech difficulties and was vague and inattentive. Albert hated the kind of rote learning he was obliged to do in school, memorizing dates and texts. But as he grew older, it became clear that Albert was no ordinary person. 1905 is often termed his 'miracle year', the year he published not one but four entirely new papers, on four completely different topics.

    It is the history of who you are and how you came to be. It is unique to you, as it is to each of the 100 billion modern humans who have ever drawn breath. But it is also our collective story, because in every one of our genomes we each carry the history of our species births, deaths, disease, war, famine, migration, and a lot of sex. Since scientists first read the human genome in 2001, it has been subject to all sorts of claims, counterclaims, and myths. In fact, as Adam Rutherford explains, our genomes should be read not as instruction manuals, but as epic poems. DNA determines far less than we have been led to believe about us as individuals, but vastly more about us as a species. In this captivating journey through the expanding landscape of genetics, Adam Rutherford reveals what our genes now tell us about history, and what history tells us about our genes. From Neanderthals to murder, from redheads to race, dead kings to plague, evolution to epigenetics, this is a demystifying and illuminating new portrait of who we are and how we came to be."

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    But Max Leonard, himself an accomplished amateur cyclist, does not forget the pain, the glory, the sweat, and the tears that go into these grueling climbs.  After all, cycling up a mountain is hard.  So hard that, to many, it can seem absurd. But for others, climbing a mountain gracefully (and beating your competitors up the slope) represents the pinnacle of cycling achievement. It is where legends are forged.Many books tell you where the mountains are, or how long and how high. None of them ask why. Why are mountain ranges professional cycling’s Coliseum? Why do amateurs also make pilgrimages to these high, remote roads? Why are the roads even there in the first place to lure us on to these obsession inducing climbs?   Just why are mountains so enthralling? “This is real cycling, where the glory is and where dreams come true,” according to Bradley Wiggins. Mountains are where cycling's greatest heroes have made their names. Every amateur rider wishes they could climb better, too.  Are all these people addicted to the pain? To the achievement? Or to the allure of the peaks? Some spend their weekends and holidays cycling up mountains from start to finish. But how does a rider push themselves beyond their limits to get up a 10% gradient on pedal power alone? What is happening when they do?A Higher Calling explores the central place of mountains in the folklore of road cycling. Blending adventure and travel writing with the rich narrative of racing, Max Leonard takes the reader from the battles that created the Alpine roads to the shepherds tending their flocks on the peaks, and to a Grand Tour climax on the “highest road in Europe.” And he tells stories of courage and sacrifice, war and love, obsession and even elephants, along the way.

    On the one hand wrens are ubiquitous. They are Britain's most common bird, with 8.5 million breeding pairs and have by far the loudest song in proportion to their size. They also thrive up and down Britain and Ireland: from the smallest city garden to remote offshore islands, blustery moors to chilly mountains. Yet many people, particularly a younger generation, are not sure if they have ever seen a wren. Perhaps because the wren is so tiny, weighing just as much as two A4 sheets of paper, and so busy, always on the move, more mouse than bird. However if we cast our eyes back to recent history wrens were a mainstay of literary, cultural and popular history. The wren was on postage stamps and the farthing, it featured in nursery rhymes and greetings cards, poems and rural `wren hunts', still a recent memory in Ireland particularly. With beautiful illustrations throughout, this captivating year-in-the-life biography reveals the hidden secrets of this fascinating bird that lives right on our doorstep.

    

    Worms are the latest (as well as, of course, perhaps the oldest!) trend in earth-friendly gardening, and in this handy guide, the authors of DEAD SNAILS LEAVE NO TRAILS demystify the world of worm wrangling, with everything you need to know to build your own worm bin, make your garden worm-friendly, pamper your soil, and much much more.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    What is it like to try to heal the body when the mind is under attack? In this book, Dr. Allan Ropper and Brian Burrell take the reader behind the scenes at Harvard Medical School's neurology unit to show how a seasoned diagnostician faces down bizarre, life-altering afflictions. Like Alice in Wonderland, Dr. Ropper inhabits a world where absurdities abound:• A figure skater whose body has become a ticking time-bomb • A salesman who drives around and around a traffic rotary, unable to get off • A college quarterback who can't stop calling the same play • A child molester who, after falling on the ice, is left with a brain that is very much dead inside a body that is very much alive • A mother of two young girls, diagnosed with ALS, who has to decide whether a life locked inside her own head is worth livingHow does one begin to treat such cases, to counsel people whose lives may be changed forever? How does one train the next generation of clinicians to deal with the moral and medical aspects of brain disease? Dr. Ropper and his colleague answer these questions by taking the reader into a rarified world where lives and minds hang in the balance.
