With plenty of engaging material, practice questions, and practical ideas, this updated edition contains everything your students need to succeed in Cambridge IGCSE biology.

     Early studies of the functions of the human brain used a simple method: wait for misfortune to strike-strokes, seizures, infectious diseases, lobotomies, horrendous accidents-and see how the victim coped. In many cases survival was miraculous, and observers could only marvel at the transformations that took place afterward, altering victims' personalities. An injury to one section can leave a person unable to recognize loved ones; some brain trauma can even make you a pathological gambler, pedophile, or liar. But a few scientists realized that these injuries were an opportunity for studying brain function at its extremes. With lucid explanations and incisive wit, Sam Kean explains the brain's secret passageways while recounting forgotten stories of common people whose struggles, resiliency, and deep humanity made modern neuroscience possible.

    "Reading The Neanderthal Enigma is like sitting down with a wonderful storyteller in the cave where stories began." -- Jonathan Weiner, author of The Beak of the Finch..

    Kennedy, more than one hundred witnesses, investigators, and other people linked to the ambush in Dealey Plaza have died. The majority have met their fate under extremely suspicious circumstances. Murders, mysterious accidents, and "suicides" account for more than half of those who have died since that fateful day in 1963. In "JFK: The Dead Witnesses" authors Craig Roberts and John Armstrong present the results of their investigations into the deaths of each of the victims. For the first time, the cases are detailed in chronological order exposing what each witness saw, what they might know, know they died, and how they were connected to the murder of JFK and often, to each other. Follow the trail of bodies through thirty years of intrigue, coverups and scandals as Roberts and Armstrong open the curtain that have for too long hidden the facts behind…the dead witnesses!

    Colin Tudge argues that we are entering a new phase of biology in which, for the first time, biologists are achieving profound insight into life's true diversity and developing the tools to keep track of it. The Variety of Life heralds this new phase. The first part of the book describes why biologists now feel that there could have been as many as 4,000 billion species on Earth since life began. It then discusses the need for classification, beginning with the most basic principles--the strictly practical classification of fishmongers and foresters, who speak of "shellfish" and differentiate "hardwood" from "softwood"--and moves on to explore the intriguing deliberations of the modern "transformed cladists" and the novel contributions of molecular genetics. Part II describes the creatures themselves. It is divided into 24 sections, each describing a different group, illustrated by nearly 50 double-page spreads which present genealogical "trees" that summarize the evolutionary relationships between the creatures in each group. Some sections describe large, comprehensive groups such as the kingdoms of the Animals or the Plants. Others treat similar sub-groups in more detail, such as the Mammals, a class, or the Hominids, a family. In lively and accessible prose, all the significant groups of creatures--both alive and extinct--are described and their relationships clarified. For general readers and serious biologists alike, The Variety of Life offers an unprecedented storehouse of knowledge of life on earth.

    

    

    Proudly dubbed “an entirely synthetic fish” by fisheries managers, the rainbow trout has been introduced into every state and province in the United States and Canada and to every continent except Antarctica, often with devastating effects on the native fauna. Halverson examines the paradoxes and reveals a range of characters, from nineteenth-century boosters who believed rainbows could be the saviors of democracy to twenty-first-century biologists who now seek to eradicate them from waters around the globe. Ultimately, the story of the rainbow trout is the story of our relationship with the natural world—how it has changed and how it startlingly has not.

    For millions, the Galápagos Islands represent nature at its most unspoiled, an inviolate place famed for its rare flora and fauna. But soon today’s 30,000 human residents could surpass 50,000. Add invasive species, floods of tourists, and unresolved conflicts between Ecuadorian laws and local concerns, and it’s easy to see why the Galápagos were recently added to UNESCO’s World Heritage in Danger list. Each chapter in this provocative, perceptive book focuses on a specific person or group with a stake in the Galápagos’ natural resources—from tour companies whose activities are often illegal and not always green, to creationist guides who lead tours with no mention of evolution, from fishermen up in arms over lobster quotas, to modern-day pirates who poach endangered marine species. Bassett presents a perspective as readable as it is sensible. Told with wit, passion, and grace, the Galápagos story serves as a miniature model of Earth itself, a perfect example of how an environment can be destroyed-- and what is being done to preserve these islands before it's too late.

    This riveting narrative offers an account of COVID-19, reminding us of women's leadership and resilience, reflecting back hope and humanity as we all figure out a new normal, together. Throughout history, men have fought, lost, and led us through the world's defining crises. That all changed with COVID-19. In Canada, women's presence in the response to the pandemic has been notable. Women are our nurses, doctors, PSWs. Our cashiers, long-haulers, cooks. In Canada, women are leading the fast-paced search for a vaccine. They are leading our provinces and territories. At home, they are leading families through self-isolation, often bearing the responsibility for their physical and emotional health. They are figuring out what working from home looks like, and many of them are doing it while homeschooling their kids. Women crafted the blueprint for kindness during the pandemic, from sewing masks to kicking off international mutual-aid networks. And, perhaps not surprisingly, women have also suffered some of the biggest losses, bearing the brunt of our economic skydive. Through intimate portraits of Canadian women in diverse situations and fields, Women of the Pandemic is a gripping narrative record of the early months of COVID-19, a clear-eyed look at women's struggles, which highlights their creativity, perseverance, and resilience as they charted a new path forward during impossible times.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    We like to imagine that it’s based on evidence and the results of fair tests. In reality, those tests are often profoundly flawed. We like to imagine that doctors are familiar with the research literature surrounding a drug, when in reality much of the research is hidden from them by drug companies. We like to imagine that doctors are impartially educated, when in reality much of their education is funded by industry. We like to imagine that regulators let only effective drugs onto the market, when in reality they approve hopeless drugs, with data on side effects casually withheld from doctors and patients.All these problems have been protected from public scrutiny because they’re too complex to capture in a sound bite. But Dr. Ben Goldacre shows that the true scale of this murderous disaster fully reveals itself only when the details are untangled. He believes we should all be able to understand precisely how data manipulation works and how research misconduct on a global scale affects us. In his own words, “the tricks and distortions documented in these pages are beautiful, intricate, and fascinating in their details.” With Goldacre’s characteristic flair and a forensic attention to detail, Bad Pharma reveals a shockingly broken system and calls for something to be done. This is the pharmaceutical industry as it has never been seen before.

    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.

    We walk on it, drive on it, and many of us live and work within its walls. But very few of us know what it is. We take for granted this ubiquitous substance, which both literally and figuratively comprises much of modern civilization’s constructed environment; yet the story of its creation and development features a cast of fascinating characters and remarkable historical episodes. This book delves into this history, opening readers’ eyes at every turn.In a lively narrative peppered with intriguing details, author Robert Corland describes how some of the most famous personalities of history became involved in the development and use of concrete—including King Herod the Great of Judea, the Roman emperor Hadrian, Thomas Edison (who once owned the largest concrete cement plant in the world), and architect Frank Lloyd Wright. Courland points to recent archaeological evidence suggesting that the discovery of concrete directly led to the Neolithic Revolution and the rise of the earliest civilizations. Much later, the Romans reached extraordinarily high standards for concrete production, showcasing their achievement in iconic buildings like the Coliseum and the Pantheon. Amazingly, with the fall of the Roman Empire, the secrets of concrete manufacturing were lost for over a millennium. The author explains that when concrete was rediscovered in the late eighteenth century it was initially viewed as an interesting novelty or, at best, a specialized building material suitable only for a narrow range of applications. It was only toward the end of the nineteenth century that the use of concrete exploded. During this rapid expansion, industry lobbyists tried to disguise the fact that modern concrete had certain defects and critical shortcomings. It is now recognized that modern concrete, unlike its Roman predecessor, gradually disintegrates with age. Compounding this problem is another distressing fact: the manufacture of concrete cement is a major contributor to global warming. Concrete Planet is filled with incredible stories, fascinating characters, surprising facts, and an array of intriguing insights into the building material that forms the basis of the infrastructure on which we depend.

    Throughout this fascinating book, Clifford Pickover invites us to share in the amazing adventures of brilliant, quirky, and passionate people after whom these laws are named. These lawgivers turn out to be a fascinating, diverse, and sometimes eccentric group of people. Many were extremely versatile polymaths--human dynamos with a seemingly infinite supply of curiosity and energy and who worked in many different areas in science. Others had non-conventional educations and displayed their unusual talents from an early age. Some experienced resistance to their ideas, causing significant personal anguish. Pickover examines more than 40 great laws, providing brief and cogent introductions to the science behind the laws as well as engaging biographies of such scientists as Newton, Faraday, Ohm, Curie, and Planck. Throughout, he includes fascinating, little-known tidbits relating to the law or lawgiver, and he provides cross-references to other laws or equations mentioned in the book. For several entries, he includes simple numerical examples and solved problems so that readers can have a hands-on understanding of the application of the law. A sweeping survey of scientific discovery as well as an intriguing portrait gallery of some of the greatest minds in history, this superb volume will engage everyone interested in science and the physical world or in the dazzling creativity of these brilliant thinkers.
