Over the last two decades, it has emerged as a powerful tool for solving crimes and determining guilt and innocence. But, very recently, an important new aspect of DNA has been revealed—it contains a detailed record of evolution. That is, DNA is a living chronicle of how the marvelous creatures that inhabit our planet have adapted to its many environments, from the freezing waters of the Antarctic to the lush canopy of the rain forest.In the pages of this highly readable narrative, Sean Carroll guides the general reader on a tour of the massive DNA record of three billion years of evolution to see how the fittest are made. And what a eye-opening tour it is—one featuring immortal genes, fossil genes, and genes that bear the scars of past battles with horrible diseases. This book clinches the case for evolution, beyond any reasonable doubt.

    Buzz Aldrin, one of the first moonwalkers, has no shortage of these ideas. And in Mission to Mars he treats us to how, when, and why we should travel there." -Neil deGrasse TysonLegendary "space statesman" Buzz Aldrin speaks out as a vital advocate for the continuing quest to push the boundaries of the universe as we know it. As a pioneering astronaut who first set foot on the moon during mankind's first landing of Apollo 11--and as an aerospace engineer who designed an orbital rendezvous technique critical to future planetary landings--Aldrin has a vision, and in this book he plots out the path he proposes, taking humans to Mars by 2035.Foreword by Andrew AldrinChapter 1: The View from Air Force OneChapter 2: Time for Decision-makingChapter 3: Your Space: Building the Business CaseChapter 4: Dreams of My MoonChapter 5: Voyage to ArmageddonChapter 6: The March to MarsChapter 7: Homesteading the Red PlanetChapter 8: The Clarion Call

    The most fatal virus known to science, rabies — a disease that spreads avidly from animals to humans — kills nearly one hundred percent of its victims once the infection takes root in the brain. In this critically acclaimed exploration, journalist Bill Wasik and veterinarian Monica Murphy chart four thousand years of the history, science, and cultural mythology of rabies. From Greek myths to zombie flicks, from the laboratory heroics of Louis Pasteur to the contemporary search for a lifesaving treatment, Rabid is a fresh and often wildly entertaining look at one of humankind’s oldest and most fearsome foes.

    Geological Survey, a lively and revealing history of the world's most disruptive natural disasters, their impact on our culture, and new ways of thinking about the ones to comeNatural disasters emerge from the same forces that give our planet life. Earthquakes have provided us with natural springs. Volcanoes have given us fertile soil. A world without floods would be a world without rain. It is only when these forces exceed our ability to withstand them that they become disasters. Together, these colossal events have shaped our cities and their architecture; elevated leaders and toppled governments; influenced the way we reason, feel, fight, unite, and pray. The history of natural disasters is a history of ourselves.The Big Ones is a look at some of the most devastating disasters in human history, whose reverberations we continue to feel today. It considers Pompeii, and how a volcanic eruption in the first century AD challenged and reinforced prevailing views of religion for centuries to come. It explores the California floods of 1862, examining the failures of our collective memory. And it transports us to today, showing what Hurricane Katrina and the 2004 Indian Ocean tsunami can tell us about governance and globalization. With global temperatures rising, natural disasters are striking with greater frequency. More than just history, The Big Ones is a call to action. Natural disasters are inevitable; human catastrophes are not. With this energizing and richly researched book, Jones offers a look at our past, readying us to face down the Big Ones in our future.

    A starry night is one of nature's most magical wonders, yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision, and most no longer experience true darkness. In The End of Night, Paul Bogard restores awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.From Las Vegas's Luxor Beam (the brightest single spot on this planet) to nights so starlit the sky looks like snow, Bogard blends personal narrative, natural history, science, and history to shed light on the importance of darkness--what we've lost, what we still have, and what we might regain--and the simple ways we can reduce the brightness of our nights tonight.

    It intersects with Darwin’s theory of evolution, and collides with the horrors of Nazi eugenics in the 1940s. The gene transforms post-war biology. It reorganizes our understanding of sexuality, temperament, choice and free will. This is a story driven by human ingenuity and obsessive minds – from Charles Darwin and Gregor Mendel to Francis Crick, James Watson and Rosalind Franklin, and the thousands of scientists still working to understand the code of codes.This is an epic, moving history of a scientific idea coming to life, by the author of The Emperor of All Maladies. But woven through The Gene, like a red line, is also an intimate history – the story of Mukherjee’s own family and its recurring pattern of mental illness, reminding us that genetics is vitally relevant to everyday lives. These concerns reverberate even more urgently today as we learn to “read” and “write” the human genome – unleashing the potential to change the fates and identities of our children.Majestic in its ambition, and unflinching in its honesty, The Gene gives us a definitive account of the fundamental unit of heredity – and a vision of both humanity’s past and future.

    Confusing messages from health authorities and ineffective treatments have left many people desperate for reliable solutions. An enormous alternative industry is filling the void, selling products that are often of questionable safety and totally unknown effectiveness.In Clean, doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today. He talks to dermatologists, microbiologists, allergists, immunologists, aestheticians, bar-soap enthusiasts, venture capitalists, Amish people, theologians, and straight-up scam artists, trying to figure out what it really means to be clean. He even experiments with giving up showers entirely, and discovers that he is not alone.Along the way he realizes that most of our standards of cleanliness are less related to health than most people think. A major part of the picture has been missing: a little-known ecosystem known as the skin microbiome--the trillions of microbes that live on our skin and in our pores. These microbes are not dangerous; they're more like an outer layer of skin that no one knew we had, and they influence everything from acne, eczema, and dry skin to how we smell. The new goal of skin care will be to cultivate a healthy biome--and to embrace the meaning of "clean" in the natural sense. This can mean doing much less, saving time, money, energy, water, and plastic bottles in the process.Lucid, accessible, and deeply researched, Clean explores the ongoing, radical change in the way we think about our skin, introducing readers to the emerging science that will be at the forefront of health and wellness conversations in coming years.

    But this is not the whole story.Shedding light on controversial research and investigating the ferocious gender wars in biology, psychology and anthropology, Angela Saini takes readers on an eye-opening journey to uncover how women are being rediscovered. She explores what these revelations mean for us as individuals and as a society, revealing an alternative view of science in which women are included, rather than excluded.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    . . and then broke? How would you survive? Could you improve on humanity's original timeline? And how hard would it be to domesticate a giant wombat? With this book as your guide, you'll survive--and thrive--in any period in Earth's history. Bestselling author and time-travel enthusiast Ryan North shows you how to invent all the modern conveniences we take for granted--from first principles. This illustrated manual contains all the science, engineering, art, philosophy, facts, and figures required for even the most clueless time traveler to build a civilization from the ground up. Deeply researched, irreverent, and significantly more fun than being eaten by a saber-toothed tiger, How to Invent Everything will make you smarter, more competent, and completely prepared to become the most important and influential person ever.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    In this masterfully written and brilliantly informed work of scientific history and explanation, Dr. Thorne, the Feynman Professor of Theoretical Physics at Caltech, leads his readers through an elegant, always human, tapestry of interlocking themes, coming finally to a uniquely informed answer to the great question: what principles control our universe and why do physicists think they know the things they think they know? Stephen Hawking's A Brief History of Time has been one of the greatest best-sellers in publishing history. Anyone who struggled with that book will find here a more slowly paced but equally mind-stretching experience, with the added fascination of a rich historical and human component.

    In this book, he expands the points he has made, and claims that this debate is not so much about religion versus science, as about the nature of science itself. With infectious enthusiasm, he reveals the mechanics of evolutionary theory, explains how it is rooted in the testable and verifiable scientific method, and why it is therefore a sound explanation of our beginning. He argues passionately that to continue to assert otherwise, to continue to insist that creationism has a place in the science classroom is harmful not only to our children, but to the future of the greater world as well.

    In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed.Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover?Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in 10 accessible and engaging lessons.In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers - and many more questions - in this pocket-sized tour of the universe!
