The renowned biologist Daniel Chamovitz builds on the original edition to present an intriguing look at how plants themselves experience the world—from the colors they see to the schedules they keep, and now, what they do in fact hear and how they are able to taste. A rare inside look at what life is really like for the grass we walk on, the flowers we sniff, and the trees we climb, What a Plant Knows offers a greater understanding of their place in nature.

    In the last century, there have been massive breakthroughs that have rewritten the science of the brain, and yet the puzzles faced by the ancient Greeks are still present. In The Consciousness Instinct, the neuroscience pioneer Michael S. Gazzaniga puts the latest research in conversation with the history of human thinking about the mind, giving a big-picture view of what science has revealed about consciousness.The idea of the brain as a machine, first proposed centuries ago, has led to assumptions about the relationship between mind and brain that dog scientists and philosophers to this day. Gazzaniga asserts that this model has it backward--brains make machines, but they cannot be reduced to one. New research suggests the brain is actually a confederation of independent modules working together. Understanding how consciousness could emanate from such an organization will help define the future of brain science and artificial intelligence and close the gap between brain and mind.Captivating and accessible, with insights drawn from a lifetime at the forefront of the field, The Consciousness Instinct sets the course for the neuroscience of tomorrow.

    The pages take the reader on a wild narrative ride through the world of squid science and adventure, along the way addressing some riddles about what intelligence is, and what monsters lie in the deep. In addition to squid, both giant and otherwise, Kraken examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Accessible and entertaining, Kraken is also the first substantial volume on the subject in more than a decade and a must for fans of popular science.

    How can it be possible that the world we see is not objective reality? And how can our senses be useful if they are not communicating the truth? Hoffman grapples with these questions and more over the course of this eye-opening work.Ever since Homo sapiens has walked the earth, natural selection has favored perception that hides the truth and guides us toward useful action, shaping our senses to keep us alive and reproducing. We observe a speeding car and do not walk in front of it; we see mold growing on bread and do not eat it. These impressions, though, are not objective reality. Just like a file icon on a desktop screen is a useful symbol rather than a genuine representation of what a computer file looks like, the objects we see every day are merely icons, allowing us to navigate the world safely and with ease.The real-world implications for this discovery are huge. From examining why fashion designers create clothes that give the illusion of a more “attractive” body shape to studying how companies use color to elicit specific emotions in consumers, and even dismantling the very notion that spacetime is objective reality, The Case Against Reality dares us to question everything we thought we knew about the world we see.

    In The Viral Storm, award-winning biologist Nathan Wolfe tells the story of how viruses and human beings have evolved side by side through history; how deadly viruses like HIV, swine flu, and bird flu almost wiped us out in the past; and why modern life has made our species vulnerable to the threat of a global pandemic.Wolfe's research missions to the jungles of Africa and the rain forests of Borneo have earned him the nickname "the Indiana Jones of virus hunters," and here Wolfe takes readers along on his groundbreaking and often dangerous research trips—to reveal the surprising origins of the most deadly diseases and to explain the role that viruses have played in human evolution.In a world where each new outbreak seems worse than the one before, Wolfe points the way forward, as new technologies are brought to bear in the most remote areas of the world to neutralize these viruses and even harness their power for the good of humanity. His provocative vision of the future will change the way we think about viruses, and perhaps remove a potential threat to humanity's survival.

    In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: the union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.

    Drawing on exclusive accounts from whistleblowers and regulators, as well as thousands of pages of confidential FDA documents, Eban reveals an industry where fraud is rampant, companies routinely falsify data, and executives circumvent almost every principle of safe manufacturing to minimize cost and maximize profit, confident in their ability to fool inspectors. Meanwhile, patients unwittingly consume medicine with unpredictable and dangerous effects.The story of generic drugs is truly global. It connects middle America to China, India, sub-Saharan Africa and Brazil, and represents the ultimate litmus test of globalization: what are the risks of moving drug manufacturing offshore, and are they worth the savings? A decade-long investigation with international sweep, high-stakes brinkmanship and big money at its core, Bottle of Lies reveals how the world’s greatest public-health innovation has become one of its most astonishing swindles.

    Mythologized. Controversial.A Harvard evolutionary biologist debunks the myths and cultural stereotypes surrounding testosterone and reveals its far-reaching effects on gender and sexuality, sports, relationships, and many more aspects of our everyday lives.The biological source of virility and masculinity has inspired fascination, investigation, and controversy since antiquity. From the eunuchs in the royal courts of ancient China to the booming market for “elixirs” of youth in nineteenth-century Europe, humans have been obsessed with identifying and manipulating what we now know as testosterone. And the trends show no signs of slowing down—the modern market for testosterone supplements is booming. Thanks to this history and the methods of modern science, today we have a rich body of research about testosterone’s effects in both men and women.The science is clear: testosterone is a major, invisible player in our relationships, sex lives, athletic abilities, childhood play, gender transitions, parenting roles, violent crime, and so much more. But there is still a lot of pushback to the idea that it does, in fact, cause sex differences and significantly influence behavior.Carole Hooven argues in T that acknowledging testosterone as a potent force in society doesn’t reinforce stifling gender norms or patriarchal values. Testosterone and evolution work together to produce a huge variety of human behavior, and that includes a multitude of ways to be masculine or feminine. Understanding the science sheds light on how we work and relate to one another, how we express anger and love, and how we can fight bias and problematic behavior to build a more fair society.

    But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all of our inventions -- our tools, farms, machines, cities, nations -- we carry with us innate proclivities to make a good society.In Blueprint, Nicholas A. Christakis introduces the compelling idea that our genes affect not only our bodies and behaviors, but also the ways in which we make societies, ones that are surprisingly similar worldwide.With many vivid examples -- including diverse historical and contemporary cultures, communities formed in the wake of shipwrecks, commune dwellers seeking utopia, online groups thrown together by design or involving artificially intelligent bots, and even the tender and complex social arrangements of elephants and dolphins that so resemble our own -- Christakis shows that, despite a human history replete with violence, we cannot escape our social blueprint for goodness.In a world of increasing political and economic polarization, it's tempting to ignore the positive role of our evolutionary past. But by exploring the ancient roots of goodness in civilization, Blueprint shows that our genes have shaped societies for our welfare and that, in a feedback loop stretching back many thousands of years, societies are still shaping our genes today.

    In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life.We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

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

    As a result, antibiotic resistance now ranks among the gravest medical problems of modern times. Good Germs, Bad Germs addresses not only this issue but also what has become known as the "hygiene hypothesis"-- an argument that links the over-sanitation of modern life to now-epidemic increases in immune and other disorders. In telling the story of what went terribly wrong in our war on germs, Jessica Snyder Sachs explores our emerging understanding of the symbiotic relationship between the human body and its resident microbes--which outnumber its human cells by a factor of nine to one! The book also offers a hopeful look into a future in which antibiotics will be designed and used more wisely, and beyond that, to a day when we may replace antibacterial drugs and cleansers with bacterial ones--each custom-designed for maximum health benefits.

    They force us to confront a fundamental biological problem: how can something as large and complex as a human body organize itself from the simplicity of a fertilized egg? A convergence of ideas from embryology, genetics, physics, networks, and control theory has begun to provide real answers. Based on the central principle of 'adaptive self-organization, ' it explains how the interactions of many cells, and of the tiny molecular machines that run them, can organize tissue structures vastly larger than themselves, correcting errors as they go along and creating new layers of complexity where there were none before.Life Unfolding tells the story of human development from egg to adult, from this perspective, showing how our whole understanding of how we come to be has been transformed in recent years. Highlighting how embryological knowledge is being used to understand why bodies age and fail, Jamie A. Daviesexplores the profound and fascinating impacts of our newfound knowledge.

    In fact, your body is actually endowed with many self-defense measures to hold on to fat. For example, fat can use stem cells to regenerate; increase our appetite if it feels threatened; and use bacteria, genetics, and viruses to expand itself. The secret to losing twenty pounds? You have to work with your fat, not against it. Tara explains how your fat influences your appetite and willpower, how it defends itself when attacked, and why it grows back so quickly. The Secret Life of Fat brings cutting-edge research together with historical perspectives to reveal fat’s true identity: an endocrine organ that, in the right amount, is critical to our health. Fat triggers puberty, enables our reproductive and immune systems, and even affects brain size.Although we spend $60 billion annually fighting fat, our efforts are often misinformed and misdirected. Tara expertly illustrates the complex role that genetics, hormones, diet, exercise, and history play in our weight, and The Secret Life of Fat sets you on the path to beat the bulge once and for all.
