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

    Our memory is unreliable; we can't multiply large sums in our heads; advertising manipulates our judgment; we tend to distrust people who are different from us; supernatural beliefs and superstitions are hard to shake; we prefer instant gratification to long-term gain; and what we presume to be rational decisions are often anything but. Drawing on striking examples and fascinating studies, neuroscientist Dean Buonomano illuminates the causes and consequences of these "bugs" in terms of the brain's innermost workings and their evolutionary purposes. He then goes one step further, examining how our brains function-and malfunction-in the digital, predator-free, information-saturated, special effects-addled world that we have built for ourselves. Along the way, Brain Bugs gives us the tools to hone our cognitive strengths while recognizing our inherent weaknesses.

    Barash, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personalaspects of being human.Homo Mysterious examines a number of these evolutionary mysteries, exploring things that we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse. Why do women experience orgasm? Why do men have a shorterlifespan than women? Why does homosexuality exist? Why does religion exist in virtually every culture? Why do we have a fondness for the arts? Why do we have such large brains? And why does consciousness exist? Readers are plunged into an ocean of unknowns--the blank spots on the human evolutionarymap, the terra incognita of our own species--and are introduced to the major hypotheses that currently occupy scientists who are attempting to unravel each puzzle (including some solutions proposed here for the first time). Throughout the book, readers are invited to share the thrill of science atits cutting edge, a place where we know what we don't know, and, moreover, where we know enough to come up with some compelling and seductive explanations.Homo Mysterious is a guide to creative thought and future explorations, based on the best, most current thinking by evolutionary scientists. It captures the allure of the not-yet-known for those interested in stretching their scientific imaginations.

    Seventeen of them had not developed interstellar travel. Those were destroyed by the species that did reach the stars. That space-faring eighteenth decimated the human colony on the Semi-Autonomous World Troy. A Marine Force Recon platoon sent to investigate is wiped out almost to the last man. In reaction, the North American Union assembles the largest army seen since the major wars of the 20th Century. A Marine Corps Combat Force is sent to "kick in the door," backed up by a four-division Army corps to take the planet back. The initial landing is unopposed. It isn't until the fleet carrying the Army corps is approaching Troy that the enemy strikes, with devastating effect.

    Nuclear devastation. Bio-hazards. The Large Hadron Collider. What do these things have in common? They all have the potential to end our world. Every great scientific creation of man is balanced by an equal amount of danger—as there’s no progress without risk. Armageddon Science is an authoritative look at the real “mad science” at work today, that recklessly puts life on Earth at risk for the pursuit of knowledge and personal gain. This book explores the reality of the dangers that science poses to the human race, from the classic fear of nuclear destruction to the latest possibilities for annihilation. Combining the science behind those threats with an understanding of the real people responsible as well as providing an assessment of the likelihood of the end of the world, this isn’t a disaster movie, it’s Armageddon Science.

    Now in paperback, Dr Jeffrey Schwartz and Sharon Begley's groundbreaking work, The Mind and the Brain, argues exactly the opposite: that the mind has a life of its own.Dr Schwartz, a leading researcher in brain dysfunctions, and Wall Street Journal science columnist Sharon Begley demonstrate that the human mind is an independent entity that can shape and control the functioning of the physical brain. Their work has its basis in our emerging understanding of adult neuroplasticity–the brain's ability to be rewired not just in childhood, but throughout life, a trait only recently established by neuroscientists.Through decades of work treating patients with obsessive–compulsive disorder (OCD), Schwartz made an extraordinary finding: while following the therapy he developed, his patients were effecting significant and lasting changes in their own neural pathways. It was a scientific first: by actively focusing their attention away from negative behaviors and toward more positive ones, Schwartz's patients were using their minds to reshape their brains–and discovering a thrilling new dimension to the concept of neuroplasticity.The Mind and the Brain follows Schwartz as he investigates this newly discovered power, which he calls self–directed neuroplasticity or, more simply, mental force. It describes his work with noted physicist Henry Stapp and connects the concept of 'mental force' with the ancient practice of mindfulness in Buddhist tradition. And it points to potential new applications that could transform the treatment of almost every variety of neurological dysfunction, from dyslexia to stroke–and could lead to new strategies to help us harness our mental powers. Yet as wondrous as these implications are, perhaps even more important is the philosophical dimension of Schwartz's work. For the existence of mental force offers convincing scientific evidence of human free will, and thus of man's inherent capacity for moral choice.

    And certainly no one wants to overeat for years, become overweight, and end up with a high risk of diabetes or heart disease--yet two thirds of Americans do precisely that. Even though we know better, we often eat too much. Why does our behavior betray our own intentions to be lean and healthy? The problem, argues obesity and neuroscience researcher Stephan J. Guyenet, is not necessarily a lack of willpower or an incorrect understanding of what to eat. Rather, our appetites and food choices are led astray by ancient, instinctive brain circuits that play by the rules of a survival game that no longer exists. And these circuits don’t care about how you look in a bathing suit next summer.To make the case, The Hungry Brain takes readers on an eye-opening journey through cutting-edge neuroscience that has never before been available to a general audience. The Hungry Brain delivers profound insights into why the brain undermines our weight goals and transforms these insights into practical guidelines for eating well and staying slim. Along the way, it explores how the human brain works, revealing how this mysterious organ makes us who we are.

    In The Invisible Gorilla, Christopher Chabris and Daniel Simons, creators of one of psychology’s most famous experiments, use remarkable stories and counterintuitive scientific findings to demonstrate an important truth: Our minds don’t work the way we think they do. We think we see ourselves and the world as they really are, but we’re actually missing a whole lot.Again and again, we think we experience and understand the world as it is, but our thoughts are beset by everyday illusions. We write traffic laws and build criminal cases on the assumption that people will notice when something unusual happens right in front of them. We’re sure we know where we were on 9/11, falsely believing that vivid memories are seared into our minds with perfect fidelity. And as a society, we spend billions on devices to train our brains because we’re continually tempted by the lure of quick fixes and effortless self-improvement.  The Invisible Gorilla reveals the myriad ways that our intuitions can deceive us, but it’s much more than a catalog of human failings. Chabris and Simons explain why we succumb to these everyday illusions and what we can do to inoculate ourselves against their effects. Ultimately, the book provides a kind of x-ray vision into our own minds, making it possible to pierce the veil of illusions that clouds our thoughts and to think clearly for perhaps the first time.

    Is it in our genes? The structure of our brains? Our genome may determine our eye color and even aspects of our personality. But our friendships, failures, and passions also shape who we are. The question is: how?Sebastian Seung, a dynamic professor at MIT, is on a quest to discover the biological basis of identity. He believes it lies in the pattern of connections between the brain’s neurons, which change slowly over time as we learn and grow. The connectome, as it’s called, is where our genetic inheritance intersects with our life experience. It’s where nature meets nurture.Seung introduces us to the dedicated researchers who are mapping the brain’s connections, neuron by neuron, synapse by synapse. It is a monumental undertaking—the scientific equivalent of climbing Mount Everest—but if they succeed, it could reveal the basis of personality, intelligence, memory, and perhaps even mental disorders. Many scientists speculate that people with anorexia, autism, and schizophrenia are "wired differently," but nobody knows for sure. The brain’s wiring has never been clearly seen.In sparklingly clear prose, Seung reveals the amazing technological advances that will soon help us map connectomes. He also examines the evidence that these maps will someday allow humans to "upload" their minds into computers, achieving a kind of immortality.Connectome is a mind-bending adventure story, told with great passion and authority. It presents a daring scientific and technological vision for at last understanding what makes us who we are. Welcome to the future of neuroscience.

    A devastating man made virus has been unleashed on the world, a virus so lethal that it rapidly turns everyone it infects into rabid, blood crazed killers. Maniacs so devoid of humanity that their only goal in life is to rip the flesh from your very body, and kill or infect the people you love the most. Would you panic? Would you rush from your desk in a frantic attempt to save your children? Would you hunker down, and hope the infection somehow passes you by, praying to whatever God you think will help? And what if the very people you care for so deeply are the ones clawing at your door, their blood smeared faces screaming for the destruction of your soul? How would you survive in such a world? And would you want to?

    But what if our actions are driven not by our conscious values and beliefs but by hidden motivations we’re not even aware of?The “hidden brain” is Shankar Vedantam’s shorthand for a host of brain functions, emotional responses, and cognitive processes that happen outside our conscious awareness but have a decisive effect on how we behave. The hidden brain has its finger on the scale when we make all our most complex and important decisions: It decides whom we fall in love with, whether we should convict someone of murder, and which way to run when someone yells “Fire!” It explains why we can become riveted by the story of a single puppy adrift on the ocean but are quickly bored by a story of genocide. The hidden brain can also be deliberately manipulated to convince people to vote against their own interests, or even become suicide terrorists. But the most disturbing thing is that it does all this without our knowing.Shankar Vedantam, author of The Washington Post’s popular “Department of Human Behavior” column, takes us on a tour of this phenomenon and explores its consequences. Using original reporting that combines the latest scientific research with compulsively readable narratives that take readers from the American campaign trail to terrorist indoctrination camps, from the World Trade Center on 9/11 to, yes, a puppy adrift on the Pacific Ocean, Vedantam illuminates the dark recesses of our minds while making an original argument about how we can compensate for our blind spots and what happens when we don’t.
