Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field’s most recent research.Changizi focuses on four “why” questions:1. Why do we see in color?2. Why do our eyes face forward?3. Why do we see illusions?4. Why does reading come so naturally to us?Why Do We See in Color?It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi’s research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it’s no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans.Why Do Our Eyes Face Forward?Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi’s research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we’re able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You’ll find that you’re able to look “through” it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren’t blocked by our noses, beaks, etc.Why Do We See Illusions?We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn’t catch a ball because the brain’s ability to process visual information isn’t fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past,” Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving” element into the future and, as a result, we don’t see what’s on the page, but what our brain thinks will be the case a fraction of a second into the future.Why Does Reading Come So Naturally to Us?We can read faster than we can hear, which is odd, considering that reading is relatively recent, and we’ve evolved to process speech for millions of years. Changizi’s research reveals that language has been carefully designed to tap in to elements of the visual processing center that have evolved for tens of millions of years. Visual signs of all languages are shaped like objects in nature, Changizi says, because we have evolved to see nature easily. “People have noticed letters in nature for some time, and there are artists who have a spent a lot of time photographing Latin letters in natural scenes or on butterfly wings,” Changizi says. “For example, if you look at an upper corner of the room you are in, you will see three contours meeting at a point, making a shape close to that of a ‘Y.’“ The Vision Revolution expands upon how our ancestors found the shapes of Latin letters and delves into how visual signs can have similar shapes even though their inspirations come from very different environments.In addition to these four areas, The Vision Revolution explores other phenomena such as cyclopses, peeking and many more you hadn’t even thought to wonder about. Changizi shows how deeply involved these evolutionary aspects of our vision are in why we see the way we do—and what the future holds for us.“…to understand how culture interacts with vision, one must understand not just the eye’s design, but the actual mechanisms we have evolved,” Changizi says, “for culture can tap in to both the designed responses of our brains and the unintended responses.”The Vision Revolution is a book that finally gives attention to what before has been largely neglected by other works on human vision—a book that looks at the “why.”

    An epic, first-of-its-kind book, entwining leading-edge scientific discovery with the intimate stories of four individual lives, by the Pulitzer Prize–winning New York Times journalist.A terminal cancer patient rises from the grave. A medical marvel defies HIV. Two women with autoimmunity discover their own bodies have turned against them. Matt Richtel's An Elegant Defense uniquely entwines these intimate stories with science’s centuries-long quest to unlock the mysteries of sickness and health, and illuminates the immune system as never before.The immune system is our body’s essential defense network, a guardian vigilantly fighting illness, healing wounds, maintaining order and balance, and keeping us alive. Its legion of microscopic foot soldiers—from T cells to “natural killers”—patrols our body, linked by a nearly instantaneous communications grid. It has been honed by evolution over millennia to face an almost infinite array of threats.For all its astonishing complexity, however, the immune system can be easily compromised by fatigue, stress, toxins, advanced age, and poor nutrition—hallmarks of modern life—and even by excessive hygiene. Paradoxically, it is a fragile wonder weapon that can turn on our own bodies with startling results, leading today to epidemic levels of autoimmune disorders.Richtel effortlessly guides readers on a scientific detective tale winding from the Black Plague to twentieth-century breakthroughs in vaccination and antibiotics, to the cutting-edge laboratories that are revolutionizing immunology—perhaps the most extraordinary and consequential medical story of our time. The foundation that Richtel builds makes accessible revelations about cancer immunotherapy, the microbiome, and autoimmune treatments that are changing millions of lives. An Elegant Defense also captures in vivid detail how these powerful therapies, along with our behavior and environment, interact with the immune system, often for the good but always on a razor’s edge that can throw this remarkable system out of balance.Drawing on his groundbreaking reporting for the New York Times and based on extensive new interviews with dozens of world-renowned scientists, Matt Richtel has produced a landmark book, equally an investigation into the deepest riddles of survival and a profoundly human tale that is movingly brought to life through the eyes of his four main characters, each of whom illuminates an essential facet of our “elegant defense.”

    David Agus tackles these fundamental questions and dismantles misperceptions about what “health” really means. Presenting an eye-opening picture of the human body and all the ways it works—and fails—Dr. Agus shows us how a new perspective on our individual health will allow us to achieve a long, vigorous life. Offering insights and access to powerful new technologies that promise to transform medicine, Dr. Agus emphasizes his belief that there is no “right” answer, no master guide that is “one size fits all.” Each one of us must get to know our bodies in uniquely personal ways, and he shows us exactly how to do that. A bold call for all of us to become our own personal health advocates, The End of Illness is a moving departure from orthodox thinking.

    Increasingly, science is concerned with the structure, behavior, and evolution of complex systems ranging from cells to ecosystems. In Networks of the Brain, Olaf Sporns describes how the integrative nature of brain function can be illuminated from a complex network perspective.Highlighting the many emerging points of contact between neuroscience and network science, the book serves to introduce network theory to neuroscientists and neuroscience to those working on theoretical network models. Sporns emphasizes how networks connect levels of organization in the brain and how they link structure to function, offering an informal and nonmathematical treatment of the subject. Networks of the Brain provides a synthesis of the sciences of complex networks and the brain that will be an essential foundation for future research.
