It covers the biochemistry of vitamins, minerals, and energy nutrients. In addition, the text examines the structure and function of water-soluble and fat-soluble vitamins and their regulatory role in metabolism, looks at electrolyte and fluid balance, and examines the role of nutrition in the development or exacerbation of chronic disease. This text continues to set the hallmark for this course through the authorsa ability to clearly and accurately explain even the most complex metabolic processes and concepts.

    A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. First Steps examines how walking upright helped us rise above all over species on this planet.First Steps includes an eight-page color photo insert.

    Epidemiologist David Waltner-Toews gathers the latest research and draws from his work in disease prevention around the world to profile dozens of illnesses, encouraging us to re-examine our role in pandemics -- for our own health and the health of our planet.

    But the theory of evolution did not spring full-blown from the head of Darwin. Since the dawn of humanity, priests, philosophers, and scientists have debated the origin and development of life on earth, and with modern science, that debate shifted into high gear.In this lively, deeply erudite work, Pulitzer Prize–winning science historian Edward J. Larson takes us on a guided tour of Darwin’s “dangerous idea,” from its theoretical antecedents in the early nineteenth century to the brilliant breakthroughs of Darwin and Wallace, to Watson and Crick’s stunning discovery of the DNA double helix, and to the triumphant neo-Darwinian synthesis and rising sociobiology today.Along the way, Larson expertly places the scientific upheaval of evolution in cultural perspective: the social and philosophical earthquake that was the French Revolution; the development, in England, of a laissez-faire capitalism in tune with a Darwinian ethos of “survival of the fittest”; the emergence of Social Darwinism and the dark science of eugenics against a backdrop of industrial revolution; the American Christian backlash against evolutionism that culminated in the famous Scopes trial; and on to today’s world, where religious fundamentalists litigate for the right to teach “creation science” alongside evolution in U.S. public schools, even as the theory itself continues to evolve in new and surprising directions.Throughout, Larson trains his spotlight on the lives and careers of the scientists, explorers, and eccentrics whose collaborations and competitions have driven the theory of evolution forward. Here are portraits of Cuvier, Lamarck, Darwin, Wallace, Haeckel, Galton, Huxley, Mendel, Morgan, Fisher, Dobzhansky, Watson and Crick, W. D. Hamilton, E. O. Wilson, and many others. Celebrated as one of mankind’s crowning scientific achievements and reviled as a threat to our deepest values, the theory of evolution has utterly transformed our view of life, religion, origins, and the theory itself, and remains controversial, especially in the United States (where 90% of adults do not subscribe to the full Darwinian vision). Replete with fresh material and new insights, Evolution will educate and inform while taking readers on a fascinating journey of discovery.From the Hardcover edition.

    The Human Genome Project finished sequencing human DNA. It seemed it was only a matter of time until we had all the answers to the secrets of life on this planet. The cutting-edge of biology, however, is telling us that we still don't even know all of the questions. How is it that, despite each cell in your body carrying exactly the same DNA, you don't have teeth growing out of your eyeballs or toenails on your liver? How is it that identical twins share exactly the same DNA and yet can exhibit dramatic differences in the way that they live and grow? It turns out that cells read the genetic code in DNA more like a script to be interpreted than a mould that replicates the same result each time. This is epigenetics and it's the fastest-moving field in biology today. The Epigenetics Revolution traces the thrilling path this discipline has taken over the last twenty years. Biologist Nessa Carey deftly explains such diverse phenomena as how queen bees and ants control their colonies, why tortoiseshell cats are always female, why some plants need a period of cold before they can flower, why we age, develop disease and become addicted to drugs, and much more. Most excitingly, Carey reveals the amazing possibilities for humankind that epigenetics offers for us all - and in the surprisingly near future.

     "The genius of Hanson's fascinating, inspiring, and entertaining book stems from the fact that it is not about how all kinds of things grow from seeds; it is about the seeds themselves." -- Mark Kurlansky, New York Times Book Review We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life: supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and pepper drove the Age of Discovery, coffee beans fueled the Enlightenment and cottonseed sparked the Industrial Revolution. Seeds are fundamental objects of beauty, evolutionary wonders, and simple fascinations. Yet, despite their importance, seeds are often seen as commonplace, their extraordinary natural and human histories overlooked. Thanks to this stunning new book, they can be overlooked no more. This is a book of knowledge, adventure, and wonder, spun by an award-winning writer with both the charm of a fireside story-teller and the hard-won expertise of a field biologist. A fascinating scientific adventure, it is essential reading for anyone who loves to see a plant grow.

    Why do we recognize patterns? Is there such a thing as positive stress? Are we genetically programmed to be in conflict with each other? Those are just some of the 150 questions that the world's best scientific minds answer with elegant simplicity.With contributions from Jared Diamond, Richard Dawkins, Nassim Taleb, Brian Eno, Steven Pinker, and more, everything is explained in fun, uncomplicated terms that make the most complex concepts easy to comprehend.

    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.

    Yet for all our advanced scientific knowledge, only one human disease – smallpox – has ever been eradicated globally.In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes, and the panic that a rapidly spreading epidemic can ignite. But while we chase the diseases we are already aware of, new ones are constantly emerging, initiating a new race to identify them. At the same time, antimicrobial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more. Meera Senthilingam presents a timely look at humanity’s ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.

    Introduction by Professor Stephen HawkingFrom what actually happened in the Big Bang to the accidental discovery of post-it notes, science is packed with surprising discoveries. Did you know, for instance, that if you were to get too close to a black hole it would suck you up like a noodle (it's called spaghettification), why your keyboard is laid out in QWERTY (it's not to make it easier to type) or whether the invention of the wheel was less important to civilisation than the bag (think about it). New Scientist does. And now they and illustrator Jennifer Daniel want to take you on a whistlestop journey from the start of our universe (through the history of stars, galaxies, meteorites, the Moon and dark energy) to our planet (through oceans and weather to oil) and life (through dinosaurs to emotions and sex) to civilisation (from cities to alcohol and cooking), knowledge (from alphabets to alchemy) ending up with technology (computers to rocket science). Witty essays explore the concepts alongside enlightening infographics that zoom from how many people have ever lived to showing you how a left-wing brain differs from a right-wing one.

    Your head hurts. You're mildly annoyed as you get the kids ready for school and dress for work yourself. Meanwhile, an epic war is being fought, just below your skin. Millions are fighting and dying for you to be able to complain as you head out the door.So what, exactly, is your immune system?Second only to the human brain in its complexity, it is one of the oldest and most critical facets of life on Earth. Without it, you would die within days. In Immune, Philipp Dettmer, the brains behind the most popular science channel on YouTube, takes readers on a journey through the fortress of the human body and its defenses. There is a constant battle of staggering scale raging within us, full of stories of invasion, strategy, defeat, and noble self-sacrifice. In fact, in the time you've been reading this, your immune system has probably identified and eradicated a cancer cell that started to grow in your body.Each chapter delves into an element of the immune system, including defenses like antibodies and inflammation as well as threats like bacteria, allergies, and cancer, as Dettmer reveals why boosting your immune system is actually nonsense, how parasites sneak their way past your body's defenses, how viruses work, and what goes on in your wounds when you cut yourself.Enlivened by engaging graphics and immersive descriptions, Immune turns one of the most intricate, interconnected, and confusing subjects—immunology—into a gripping adventure through an astonishing alien landscape. Immune is a vital and remarkably fun crash course in what is arguably, and increasingly, the most important system in the body.

    Award-winning cultural historian Iain McCalman tells the stories of Charles Darwin and his most vocal supporters and colleagues: Joseph Hooker, Thomas Huxley, and Alfred Wallace. Beginning with the somber morning of April 26, 1882—the day of Darwin’s funeral—Darwin’s Armada steps back in time and recounts the lives and scientific discoveries of each of these explorers. The four amateur naturalists voyaged separately from Britain to the southern hemisphere in search of adventure and scientific fame. From Darwin’s inaugural trip on the Beagle in 1835 through Wallace’s exploits in the Amazon and, later, Malaysia in the 1840s and 1850s, each man independently made discoveries that led him to embrace Darwin’s groundbreaking theory of evolution. This book reveals the untold story of Darwin’s greatest supporters who, during his life, campaigned passionately in the war of ideas over evolution and who lived on to extend and advance the scope of his work. 16 pages of color illustrations.

    But the news isn't all bad.It's accepted wisdom today that human beings have permanently damaged the natural world, causing extinction, deforestation, pollution, and of course climate change. But in Inheritors of the Earth, biologist Chris Thomas shows that this obscures a more hopeful truth - we're also helping nature grow and change. Human cities and mass agriculture have created new places for enterprising animals and plants to live, and our activities have stimulated evolutionary change in virtually every population of living species. Most remarkably, Thomas shows, humans may well have raised the rate at which new species are formed to the highest level in the history of our planet.Drawing on the success stories of diverse species, from the ochre-colored comma butterfly to the New Zealand pukeko, Thomas overturns the accepted story of declining biodiversity on Earth. In so doing, he questions why we resist new forms of life, and why we see ourselves as unnatural. Ultimately, he suggests that if life on Earth can recover from the asteroid that killed off the dinosaurs, it can survive the onslaughts of the technological age. This eye-opening book is a profound reexamination of the relationship between humanity and the natural world.

    As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began. He looks at everything from our armor and camouflage to the evolution of the rifle and the structures human populations have built across different regions and eras to protect their homes and communities. With stunning black and white drawings and gorgeous color illustrations of these concepts at work, Animal Weapons brings us the complete story of how weapons reach their most outsized, dramatic potential, and what the results we witness in the animal world can tell us about our own relationship with weapons of all kinds.

    Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special. Surveying a vast field from initial bipedality to language and intelligence, Tattersall argues that Homo sapiens acquired a winning combination of traits that was not the result of long-term evolutionary refinement. Instead, the final result emerged quickly, shocking our world and changing it forever.
