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."

What gives the human brain the creative ability that defines us all as individuals? Although the silicon version is hard on its heels, the brain remains the most remarkable computer in existence. Leading us through cognitive theory, neuroscience and Darwinian evolution with his trademark wit and wisdom, Michael Corballis explains what we know - and don't know - about our minds. How do we know if we’re really the top dogs in brain power?

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.

The Arctic century is upon us. A great jockeying for power and influence has erupted among nations in the high north. At stake are trillions of dollars in profit or loss, US security, geopolitical influence and the fate of a fragile environment as well as the region's traditional people. As the ice melts and oil companies venture north, the polar regions may become the next Panama Canal, the next Arabian Peninsula-places on earth that remain relatively unknown in one century and become pivotal in the next.

A deeply panoramic tour of the night, from its brightest spots to the darkest skies we have left. 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 of us no longer experience true darkness. In The End of Night, Paul Bogard restores our awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.

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.

Why do three out of four professional football players go bankrupt? How can illiterate jungle dwellers pass a test that tricks Harvard philosophers? And why do billionaires work so hard - only to give their hard-earned money away? When it comes to making decisions, the classic view is that humans are eminently rational. But growing evidence suggests instead that our choices are often irrational, biased, and occasionally even moronic. Which view is right - or is there another possibility?

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.

What is life? Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells, and whole organisms to create new ones that could never have previously existed on their own.

The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs' clinic to the present.

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.

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.

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.

The story of evolution as you’ve never heard it before. What’s the easiest way to tell species apart? Check their genitals. Researching private parts was long considered taboo, but scientists are now beginning to understand that the wild diversity of sex organs across species can tell us a lot about evolution. Menno Schilthuizen invites listeners to join him as he uncovers the ways the shapes and functions of genitalia have been molded by complex Darwinian struggles.

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.

Expanding upon one of the most-read New York Times Magazine features of 2012, Smarter penetrates the hot new field of intelligence research to reveal what researchers call a revolution in human intellectual abilities. Shattering decades of dogma, scientists began publishing studies in 2008 showing that "fluid intelligence" - the ability to learn, solve novel problems, and get to the heart of things - can be increased through training. But is it all just hype?

In this engaging account, renowned neuroscientist Giovanni Frazzetto blends cutting-edge scientific research with personal stories to reveal how our brains generate our emotions. He demonstrates that while modern science has expanded our knowledge, investigating art, literature, and philosophy is equally crucial to unraveling the brain’s secrets. What can a brain scan, or our reaction to a Caravaggio painting, reveal about the deep seat of guilt? Can ancient remedies fight sadness more effectively than antidepressants? What can writing poetry tell us about how joy works?

Lydia Denworth presents insights from studies of everything from at-risk kids in Head Start to noisy cocktail party conversation, from songbirds to signal processing, and from the invention of the telephone to sign language. Weaving together tales from the centuries-long quest to develop the cochlear implant and simultaneous leaps in neuroscientific knowledge against a tumultuous backdrop of identity politics, I Can Hear You Whisper shows how sound sculpts our children’s brains and the life changing consequences of that delicate process.

A fascinating survey of the forces that shape who we are and how we act - from the author of The Calculus Diaries. Following her previous tours through the worlds of physics ( Black Bodies and Quantum Cats) and calculus ( The Calculus Diaries), acclaimed science writer Jennifer Ouellette now turns her attention to the mysteries of human identity and behavior with Me, Myself, and Why.

John Homans adopted his dog, Stella, from a shelter for all the usual reasons: fond memories of dogs from his past, a companion for his son, an excuse for long walks around the neighborhood. Soon enough, she is happily ensconced in the daily workings of his family. And not only that: Stella is treated like a family member - in ways that dogs of his youth were not. Spending humanlike sums on vet bills, questioning her diet and exercise regimens, contemplating her happiness - how had this all come to pass, when the dogs from Homans's childhood seemed quite content living mostly out in the yard?
