A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

Based on decades of research, Chronotherapy shows you how to harness the power of light to reset your natural clock and boost your mood, be more alert, and get a good night's sleep. A good night's sleep can be hard to get. Sleep problems and depressed mood often go hand in hand, forming a frustrating cycle. Only now are we beginning to understand the way these problems are based in the working of the brain's inner clock, through the science of chronobiology - the study of circadian rhythms and their regulation by light and darkness.

Between iPods, music-blasting restaurants, earsplitting sports stadiums, and endless air and road traffic, the place for quiet in our lives grows smaller by the day. In Pursuit of Silence gives contextto our increasingly desperatesense that noise pollution is, in a very real way, an environmental catastrophe.

Who can forget the sense of wonder with which they discovered the creatures of the deep? In this vibrant hymn to the sea, Callum Roberts - one of the world’s foremost conservation biologists - leads listeners on a fascinating tour of mankind’s relationship to the sea, from the earliest traces of water on Earth to the oceans as we know them today. In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life. 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.

50 Great Myths of Human Evolution uses common misconceptions to explore basic theory and research in human evolution and strengthen critical thinking skills for lay audiences, listeners, and students. Includes myths such as: "Humans lived at the same time as dinosaurs"; "Lucy was so small because she was a child"; "Our ancestors have always made fire"; and "There is a strong relationship between brain size and intelligence."

Every Wednesday, Gretchen Reynolds singlehandedly influences how millions of Americans work out. In her Phys Ed column for The New York Times, she debunks myths, spurs conversation, and creates arguments among her readers by questioning widely held beliefs about exercise. Expanding upon her popular columns, Reynolds tackles the questions we all have and (sometimes) ask about exercise.

When you are calm, your mind and body are in a state of focused awareness. You are in your “zone”, performing at your peak. Now, in A Calm Brain, Dr. Gayatri Devi shows how you can cultivate this optimal mental and physical state by tapping into your body’s hard-wired natural relaxation system. Our bodies have been trained to react to the beeps and alarms of all our different technologies, be it the ever present cell phone, an angry text message, or a frantic voicemail. The result is chronic stress. There is hope.

Maybe you know someone who swears by the reliability of psychics or who is in regular contact with angels. Or perhaps you're trying to find a nice way of dissuading someone from wasting money on a homeopathy cure. How do you find a gently persuasive way of steering people away from unfounded beliefs, bogus cures, conspiracy theories, and the like? Longtime skeptic Guy P. Harrison shows you how in this down-to-earth, entertaining exploration of commonly held extraordinary claims.

Science writer David DiSalvo reveals a remarkable paradox: what your brain wants is frequently not what your brain needs. In fact, much of what makes our brains "happy" leads to errors, biases, and distortions, which make getting out of our own way extremely difficult. DiSalvo's search includes forays into evolutionary and social psychology, cognitive science, neurology, and even marketing and economics - as well as interviews with many of the top thinkers in psychology and neuroscience today.

What happens when we accept that everything we feel and think stems not from an immaterial spirit but from electrical and chemical activity in our brains? In this thought-provoking narrative - drawn from professional expertise as well as personal life experiences - trailblazing neurophilosopher Patricia S. Churchland grounds the philosophy of mind in the essential ingredients of biology. She reflects with humor on how she came to harmonize science and philosophy, the mind and the brain, abstract ideals and daily life.

Our intuition about how things should behave is usually right in the everyday world. We see the baseball soar in the air, arc, drop, and lie stationary on the ground. Through data gathered by our senses and basic knowledge of the laws of classical mechanics, the motion of a ball makes perfect sense. But enter the world of the tiniest particles on earth—the motion of electrons, the shapes of molecules—and everything we think we know about the world radically changes.

Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science. In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and proposes a new model for how consciousness works.

Our world seems to be experiencing stagnant economic growth, climatic deterioration, dwindling natural resources, and an unsustainable level of population growth. The world is doomed, they argue, and there are just too many problems to overcome. But is this really the case? In Fewer, Richer, Greener, author Laurence B. Siegel reveals that the world has improved - and will continue to improve - in almost every dimension imaginable.

Is the end of HIV upon us? Award-winning research scientist and HIV fellow at the Ragon Institute, Nathalia Holt, reveals the science behind the discovery of a functional cure and what it means for the millions affected by HIV and the history of the AIDS pandemic. Two men, known in medical journals as the Berlin Patients, revealed answers to a functional cure for HIV. Their cures came 12 years apart, the first in 1996 and the second in 2008.

Supertrends: 50 Things You Need to Know About the Future is about how efficient futurists work and how we can expect the world to evolve in terms of demographics, general economics, technologies, business models, resources, environment, and lifestyles. This audiobook addresses how to predict the future, what we can expect from it, and how companies and government should adapt to the accelerating change.

The human race is at a crossroads. In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of Star Trek, where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species - or the closed, dystopian, and ultimately self-destructive world of Soylent Green. If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars.

To many, the brain is the seat of personal identity and autonomy. But the way we talk about the brain is often rooted more in mystical conceptions of the soul than in scientific fact.

Peter Bandettini covers the essentials of fMRI, providing insight and perspective from his nearly three decades of research. He describes other brain imaging and assessment methods; the sources of fMRI contrasts; the basic methodology, from hardware to pulse sequences; brain activation experiment design strategies; and data and image processing. A unique, stand-alone chapter addresses major controversies in the field, outlining 26 challenges that have helped shape fMRI research.

Is there a point to recycling? Is recycling even good for the environment? In this volume in the MIT Press Essential Knowledge series, Finn Arne Jørgensen answers: it depends. From a technical point of view, recycling is a series of processes - collecting, sorting, processing, manufacturing. Recycling also has a cultural component; at its core, recycling is about transformation and value, turning material waste into something useful - plastic bags into patio furniture, plastic bottles into T-shirts.
