Charting the most cutting-edge scientific breakthroughs, and marshalling his decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood and energy levels, regulate hormones, prevent cancer, Alzheimer's and diabetes, slow the effects of aging, and increase longevity. He also provides actionable steps towards getting a better night's sleep every night.

    In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    Encompassing a grand sweep of human history, A History of the World in 100 Objects begins with one of the earliest surviving objects made by human hands, a chopping tool from the Olduvai gorge in Africa, and ends with objects which characterise the world we live in today. Seen through MacGregor's eyes, history is a kaleidoscope - shifting, interconnected, constantly surprising, and shaping our world today in ways that most of us have never imagined. A stone pillar tells us about a great Indian emperor preaching tolerance to his people; Spanish pieces of eight tell us about the beginning of a global currency; and an early Victorian tea-set speaks to us about the impact of empire. An intellectual and visual feast, this is one of the most engrossing and unusual history books published in years. 'Brilliant, engagingly written, deeply researched' Mary Beard, Guardian 'A triumph: hugely popular, and rightly lauded as one of the most effective and intellectually ambitious initiatives in the making of 'public history' for many decades' Sunday Telegraph 'Highly intelligent, delightfully written and utterly absorbing ' Timothy Clifford, Spectator 'This is a story book, vivid and witty, shining with insights, connections, shocks and delights' Gillian Reynolds Daily Telegraph

    At once lyrical and scientific, Why We Run shows Heinrich's signature blend of biology, anthropology, psychology, and philosophy, infused with his passion to discover how and why we can achieve superhuman abilities.

    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.

    Beyond Words, readers travel to Amboseli National Park in the threatened landscape of Kenya and witness struggling elephant families work out how to survive poaching and drought, then to Yellowstone National Park to observe wolves sort out the aftermath of one pack's personal tragedy, and finally plunge into the astonishingly peaceful society of killer whales living in the crystalline waters of the Pacific Northwest.

    Moreover, present-day research on electricity and ion channels has created one of the most exciting fields in science, shedding light on conditions ranging from diabetes and allergies to cystic fibrosis, migraines, and male infertility. With inimitable wit and a clear, fresh voice, award-winning researcher Frances Ashcroft weaves together compelling real-life stories with the latest scientific findings, giving us a spectacular account of the body electric.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    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.

    Applying the same objective criteria to legal and illegal substances, an argument is made that legality is not a clear measure for harm. Tackling a variety of questions, such as Which is more harmful—Ecstasy or alcohol? Can addiction be cured? and Does the "War on Drugs" have serious unintended effects that can hurt children?, this analysis equips readers with the ability to make educated decisions regarding drugs both personally and in their communities. Broadening the scope of the discussion, a framework is explored for formulating national drug policies that will minimize a myriad of harms—social, medical, criminal, financial, and environmental.

    Then make it better.I am 94. I've had an extraordinary life. It's only now that I appreciate how extraordinary.As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day - the loss of our planet's wild places, its biodiversity.I have been witness to this decline. A Life on Our Planet is my witness statement, and my vision for the future. It is the story of how we came to make this, our greatest mistake - and how, if we act now, we can yet put it right.We have one final chance to create the perfect home for ourselves and restore the wonderful world we inherited.All we need is the will to do so.

    One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.

    Delving into topics ranging from the clash between ecological time and our culture of “perpetual now,” to the soaring history of humans changing and evolving rapidly in the face of grave threats, to rising white supremacy and fortressed borders as a form of “climate barbarism,” this is a rousing call to action for a planet on the brink. An expansive, far-ranging exploration that sees the battle for a greener world as indistinguishable from the fight for our lives, On Fire captures the burning urgency of the climate crisis, as well as the fiery energy of a rising political movement demanding a catalytic Green New Deal. “Naomi Klein’s work has always moved and guided me. She is the great chronicler of our age of climate emergency, an inspirer of generations.” —Greta Thunberg, climate activist "If I were a rich man, I’d buy 245 million copies of Naomi Klein’s 'On Fire' and hand-deliver them to every eligible voter in America…Klein is a skilled writer." —Jeff Goodell, The New York Times

    In Wicked Plants, Stewart takes on over two hundred of Mother Nature’s most appalling creations. It’s an A to Z of plants that kill, maim, intoxicate, and otherwise offend. You’ll learn which plants to avoid (like exploding shrubs), which plants make themselves exceedingly unwelcome (like the vine that ate the South), and which ones have been killing for centuries (like the weed that killed Abraham Lincoln's mother). Menacing botanical illustrations and splendidly ghastly drawings create a fascinating portrait of the evildoers that may be lurking in your own backyard. Drawing on history, medicine, science, and legend, this compendium of bloodcurdling botany will entertain, alarm, and enlighten even the most intrepid gardeners and nature lovers.

    Arguing that the processes creating the technium are akin to those of biological evolution, Kelly devotes the opening sections of his exposition to that analogy, maintaining that the technium exhibits a similar tendency toward self-organizing complexity. Having defined the technium, Kelly addresses its discontents, as expressed by the Unabomber (although Kelly admits to trepidation in taking seriously the antitechnology screeds of a murderer) and then as lived by the allegedly technophobic Amish. From his observations and discussions with some Amish people, Kelly extracts some precepts of their attitudes toward gadgets, suggesting folk in the secular world can benefit from the Amish approach of treating tools as servants of self and society rather than as out-of-control masters. Exploring ramifications of technology on human welfare and achievement, Kelly arrives at an optimistic outlook that will interest many, coming, as it does, from the former editor of Wired magazine."Gilbert Taylor, Booklist
