Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer.

From the celebrated neurobiologist and primatologist, a landmark, genre-defining examination of human behavior, both good and bad, and an answer to the question: Why do we do the things we do? Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: He starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

Eating is an indispensable human activity. As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man."

What is human consciousness, and how is it possible? This question fascinates thinking people from poets and painters to physicists, psychologists, and philosophers. From Bacteria to Bach and Back is Daniel C. Dennett's brilliant answer, extending perspectives from his earlier work in surprising directions, exploring the deep interactions of evolution, brains, and human culture.

An enthralling account of a modern voyage of discovery as we meet the clever, social birds of prey called caracaras, which puzzled Darwin, fascinate modern-day falconers, and carry secrets of our planet's deep past in their family history.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

In our unique genomes, every one of us carries the story of our species - births, deaths, disease, war, famine, migration, and a lot of sex. But those stories have always been locked away - until now. Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has completely upended what we thought we knew about ourselves. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story - from 100,000 years ago to the present.

Harper Lee’s Pulitzer prize-winning masterwork of honor and injustice in the deep south - and the heroism of one man in the face of blind and violent hatred, available now for the first time as a digital audiobook. One of the best-loved stories of all time, To Kill a Mockingbird has been translated into more than 40 languages, sold more than 30 million copies worldwide, served as the basis for an enormously popular motion picture, and was voted one of the best novels of the 20th century by librarians across the country.

In the fifth century BC, a global superpower was determined to bring truth and order to what it regarded as two terrorist states. The superpower was Persia, incomparably rich in ambition, gold, and men. The terrorist states were Athens and Sparta, eccentric cities in a poor and mountainous backwater: Greece. The story of how their citizens took on the Great King of Persia, and thereby saved not only themselves, but Western civilization as well, is as heart-stopping and fateful as any episode in history.

Bernd Heinrich involves us in his quest to get inside the mind of the raven. But as animals can be spied on only by getting quite close, Heinrich adopts ravens, thereby becoming a "raven father", as well as observing them in their natural habitat. He studies their daily routines and, in the process, paints a vivid picture of the ravens' world. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation and analysis we become their intimates, too.

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

Mama's Last Hug opens with the dramatic farewell between Mama, a dying 59-year-old chimpanzee matriarch, and biologist Jan Van Hooff. This heartfelt final meeting of two longtime friends offers a window into how deep and instantly recognizable these bonds can be. So begins Frans de Waal's whirlwind tour of new ideas and findings about animal emotions, based on his renowned studies of the social and emotional lives of chimpanzees, bonobos, and other primates.

Benjamin, Alepho, and Benson were raised among the Dinka tribe of Sudan. Their world was an insulated, close-knit community of grass-roofed cottages, cattle herders, and tribal councils. The lions and pythons that prowled beyond the village fences were the greatest threat they knew. All that changed the night the government-armed Murahiliin began attacking their villages.

At the onset of World War II, Williams formed Elephant Company and was instrumental in defeating the Japanese in Burma and saving refugees, including on his own "Hannibal Trek." Billy Williams became a media sensation during the war, telling reporters that the elephants did more for him than he was ever able to do for them, but his story has since been forgotten.

A seasoned war correspondent, Jeffrey Gettleman has covered every major conflict over the past 20 years, from Afghanistan to Iraq to the Congo. For the past decade, he has served as the East Africa bureau chief for the New York Times, fulfilling his teenage dream of living in Africa. Love, Africa is the story of how he got there - and of his difficult, winding path toward becoming a good reporter and a better man.

On April 6, 1940, explorer and future World War II spy Theodore Morde (who would one day attempt to assassinate Adolf Hitler), anxious about the perilous journey that lay ahead of him, struggled to fall asleep at the Paris Hotel in La Ceiba, Honduras. Nearly seventy years later, in the same hotel, acclaimed journalist Christopher S. Stewart wonders what he's gotten himself into.

The rules of law and society have never taken hold in the Sierra Madre, which is home to bandits, drug smugglers, cave-dwelling Tarahumara Indians, opium farmers, and other assorted outcasts. Outsiders are not welcome; drugs are the primary source of income; murder is all but a regional pastime. Fifteen years ago, journalist Richard Grant developed what he calls "an unfortunate fascination" with this lawless place. Locals warned that he would meet his death there, but he didn't believe them - until his last trip.

Halima Bashir was born into the Zaghawa tribe, whose customs have remained unchanged for centuries, in the remote western deserts of Sudan in the region of South Darfur. Halima's father named his daughter after the traditional medicine woman of the village, and she grew up in a happy and close-knit childhood environment. Her father became a wealthy man by his tribe's standards, so he could afford to send Halima to school and university. Halima went on to study medicine, and at 24 she returned to her tribe and began practicing as their first ever qualified doctor.

Earth is being invaded by the shetani - spirit creatures so small and stealthy that only one man knows about the increasing peril. The potential savior is an African elder named Olkeloki who is capable of fighting evil both in this world and the spirit one. But to be successful he must recruit the help of two others: government agent Joshua Oak, and a feisty young woman named Merry Sharrow. Only the three of them can keep the shetani from destroying reality as we know it.

Four travelers meet in Bolivia and set off into the heart of the Amazon rainforest, but what begins as a dream adventure quickly deteriorates into a dangerous nightmare, and after weeks of wandering in the dense undergrowth, the four backpackers split up into two groups. But when a terrible rafting accident separates him from his partner, Yossi is forced to survive for weeks alone against one of the wildest backdrops on the planet.

Based on years of investigative reporting and unprecedented fieldwork, Walking the Bowl immerses readers in the daily lives of four unforgettable characters: Lusabilo, a determined waste picker; Kapula, a burned-out brothel worker; Moonga, a former rock crusher turned beggar; and Timo, an ambitious gang leader. These children navigate the violent and poverty-stricken underworld of Lusaka, one of Africa’s fastest growing cities.

Khorramshahr, Iran, May 1982 - It was the bloodiest battle of one of the most brutal wars of the twentieth century, and Najah, a 29-year-old wounded Iraqi conscript, was face to face with a 13-year-old Iranian child soldier who was ordered to kill him. Instead, the boy committed an astonishing act of mercy. It was an act that decades later would save his own life.

In this new book, Kidder gives us the superb story of a hero for our time. Strength in What Remains is a wonderfully written, inspiring account of one man’s remarkable American journey and of the ordinary people who helped him–a brilliant testament to the power of will and of second chances.

In 2006, after his father was killed, Gulwali Passarlay was caught between the Taliban, who wanted to recruit him, and the Americans, who wanted to use him. To protect her son, Gulwali's mother sent him away. The search for safety would lead the 12-year-old across eight countries, from the mountains of Eastern Afghanistan through Iran and Europe to Britain. Over the course of 12 harrowing months, Gulwali endured imprisonment, hunger, cruelty, brutality, loneliness, and terror - and nearly drowned crossing the Mediterranean Sea.

In Out of Captivity, Gonsalves, Stansell, and Howes recount for the first time their amazing tale of survival, friendship, and, ultimately, rescue, tracing their five and a half years as hostages of the FARC. Their story takes you inside one of the world's most notorious terrorist organizations, going behind enemy lines with vivid and haunting imagery.

Steve Saint was five years old when his father, missionary pilot Nate Saint, was speared to death by a primitive Ecuadorian tribe. In adulthood, Steve, having left Ecuador for a successful business career, never imagined making the jungle his home again. But when that same tribe asks him to help them, Steve, his wife, and their teenage children move back to the jungle. There, Steve learns long-buried secrets about his father's murder, confronts difficult choices, and finds himself caught between two worlds.

John Marshall had read about the growth of voluntourism, and frankly, it was the only kind of extended trip he could afford. He'd heard that some peoples' lives were changed by a week of overseas service - what might half a year accomplish for his family? His wife, Traca, was all in favor of it; his kids, especially his 14-year-old daughter, were strongly opposed. Wide-Open World is the totally engaging, bluntly honest story of the Marshall family's life-changing adventure.

Un examen minucioso del comportamiento humano y una respuesta a la pregunta: ¿por qué hacemos las cosas que hacemos? Sapolsky analiza los factores en juego, desde el momento previo hasta los factores arraigados en la historia de nuestra especie y su legado evolutivo. Partiendo de una explicación neurobiológica -¿qué sucedió en el cerebro de una persona un segundo antes de que se comportara así?, ¿qué visión, sonido u olor hicieron que el sistema nervioso produjera ese comportamiento?-, pasamos a pensar en el mundo sensorial y la endocrinología.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods?

The emergence of strange new diseases is a frightening problem that seems to be getting worse. In this age of speedy travel, it threatens a worldwide pandemic. We hear news reports of Ebola, SARS, AIDS, and something called Hendra killing horses and people in Australia - but those reports miss the big truth that such phenomena are part of a single pattern. The bugs that transmit these diseases share one thing: they originate in wild animals and pass to humans by a process called spillover. David Quammen tracks this subject around the world.

The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life.

Called the Jane Goodall of wolves, world-renowned wildlife biologist Diane Boyd has spent four decades studying and advocating for wolves in the wilds of Montana near Glacier National Park. When she started in the 1970s, she was the only female biologist in the United States researching and radio-collaring wild wolves. With her two dogs for company, she faced the rigors of the Montana winter in an isolated cabin.

America's Great Plains once possessed one of the grandest wildlife spectacles of the world, equaled only by such places as the Serengeti, the Masai Mara, or the veld of South Africa. Pronghorn antelope, gray wolves, bison, coyotes, wild horses, and grizzly bears: less than 200 years ago these creatures existed in such abundance that John James Audubon was moved to write "it is impossible to describe or even conceive the vast multitudes of these animals".
