Randall never gave sleep much thought. That is, until he began sleepwalking. One midnight crash into a hallway wall sent him on an investigation into the strange science of sleep.In Dreamland, Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. Taking readers from military battlefields to children’s bedrooms, Dreamland shows that sleep isn't as simple as it seems. Why did the results of one sleep study change the bookmakers’ odds for certain Monday Night Football games? Do women sleep differently than men? And if you happen to kill someone while you are sleepwalking, does that count as murder?This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. You’ll never look at your pillow the same way again.

    He takes us on a journey through the laboratories where scientists are studying every aspect of the cell--DNA, mitochondria, stem cells, our immune systems, even age genes that can lead to a tenfold increase in life span (in worms, anyway)--all in an effort to forestall or reverse the body's (currently!) inevitable decline. With clear writing and intellectual passion, Steele shines a spotlight on a revolution already under way and offers reality-based hope.

    Each page offers simple activities that help you understand the roles of your “happy chemicals”—serotonin, dopamine, oxytocin, and endorphin. You’ll also learn how to build new habits by rerouting the electricity in your brain to flow down a new pathway, making it even easier to trigger these happy chemicals and increase feelings of satisfaction when you need them most. Filled with dozens of exercises that will help you reprogram your brain, Habits of a Happy Brain shows you how to live a happier, healthier life!

    The meme is also one of the most important--and controversial--concepts to emerge since 'The Origin of the Species' appeared nearly 150 years ago.In 'The Meme Machine' Susan Blackmore boldly asserts: "Just as the design of our bodies can be understood only in terms of natural selection, so the design of our minds can be understood only in terms of memetic selection." Indeed, Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive - making tools, for example, or using language--survived and flourished, replicating themselves in as many minds as possible. These memes then passed themselves on from generation to generation by helping to ensure that the genes of those who acquired them also survived and reproduced. Applying this theory to many aspects of human life, Blackmore offers brilliant explanations for why we live in cities, why we talk so much, why we can't stop thinking, why we behave altruistically, how we choose our mates, and much more.With controversial implications for our religious beliefs, our free will, our very sense of "self," 'The Meme Machine' offers a provocative theory everyone will soon be talking about.

    But by itself, DNA is just an inert blueprint for life. It is the ribosome--an enormous molecular machine made up of a million atoms--that makes DNA come to life, turning our genetic code into proteins and therefore into us. Gene Machine is an insider account of the race for the structure of the ribosome, a fundamental discovery that both advances our knowledge of all life and could lead to the development of better antibiotics against life-threatening diseases. But this is also a human story of Ramakrishnan's unlikely journey, from his first fumbling experiments in a biology lab to being the dark horse in a fierce competition with some of the world's best scientists. In the end, Gene Machine is a frank insider's account of the pursuit of high-stakes science.

    From the research biologist who stung himself with every conceivable insect to the world's most murderous mammals, this book explores oft-ignored but alluring facets of biology, anatomy, space exploration, nature, and more. Featuring interviews with leading researchers in the field and a large dose of wit, the author reveals the most intriguing real-world applications of science in all their glory.
