Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

The smartphones in our pockets and computers like brains. The vagaries of game theory and evolutionary biology. Nuclear weapons and self-replicating spacecrafts. All bear the fingerprints of one remarkable, yet largely overlooked, man: John von Neumann.

Fungi are everywhere. Most are harmless, some are helpful. A few are killers. Collectively, infectious fungi are the most devastating agents of disease on Earth, and a fungus that can persist in the environment without its host is here for the long haul. In gripping, accessible prose, Emily Monosson documents how changing climate, trade, and travel are making us all more vulnerable to invasion.

From a Pulitzer Prize–winning historian: a searing study of the British Empire that probes the country's pervasive use of violence throughout the twentieth century and traces how these practices were exported, modified, and institutionalized in colonies around the globe.

The national bestseller chosen by The New York Times Book Review as one of the ten best books of 1991 is now available as an audiobook. The author of Brainstorms, Daniel C. Dennett replaces our traditional vision of consciousness with a new model based on a wealth of fact and theory from the latest scientific research.

At the dawn of World War I, a young academic named John Maynard Keynes hastily folded his long legs into the sidecar of his brother-in-law’s motorcycle for an odd, frantic journey that would change the course of history. Swept away from his placid home at Cambridge University by the currents of the conflict, Keynes found himself thrust into the halls of European treasuries to arrange emergency loans and packed off to America to negotiate the terms of economic combat.

After Miss Catherine Tregowyn, poet, and Dr. Harry Bascombe, her bête noire, discover a body in the Somerville College chapel, they are declared suspects in a murder inquiry. How can they prove their innocence? The pair decide they must launch their own investigation into the strangling of Oxford don, Agatha Chenowith. But working as a team will not be easy. Their relations are anything but cordial.

Nearly a hundred years after its publication, Kurt Gödel's famous proof that every mathematical system must contain propositions that are true - yet never provable - continues to unsettle mathematics, philosophy, and computer science. Yet unlike Einstein, with whom he formed a warm and abiding friendship, Gödel has long escaped all but the most casual scrutiny of his life.

In Four Lost Cities, acclaimed science journalist Annalee Newitz takes listeners on an entertaining and mind-bending adventure into the deep history of urban life. Investigating across the centuries and around the world, Newitz explores the rise and fall of four ancient cities, each the center of a sophisticated civilization: the Neolithic site of Çatalhöyük in Central Turkey, the Roman vacation town of Pompeii in Italy, the medieval megacity of Angkor in Cambodia, and the indigenous metropolis Cahokia, which stood beside the Mississippi River where East St. Louis is today.

Santiago Ramon y Cajal is likely the most important figure in the history of biology you've never heard of. Along with Darwin and Pasteur, he ranks among the most brilliant and original biologists of the nineteenth century, and his discoveries have done for our understanding of the human brain what the work of Galileo and Sir Isaac Newton did for our conception of the physical universe. Benjamin Ehrlich's The Brain in Search of Itself is the first major biography in English of this figure, whose scientific odyssey mirrored the rocky journey of his beloved homeland of Spain.

In the 1940s and '50s, a group of eccentric geniuses - led by John von Neumann - gathered at the newly created Institute for Advanced Study in Princeton, New Jersey. Their joint project was the realization of the theoretical universal machine, an idea that had been put forth by mathematician Alan Turing. This group of brilliant engineers worked in isolation, almost entirely independent from industry and the traditional academic community. But because they relied exclusively on government funding, the government wanted its share of the results....

In this sweeping history of the ancient Near East, Amanda Podany takes listeners on a gripping journey from the creation of the world's first cities to the conquests of Alexander the Great. The book is built around the life stories of many ancient men and women, from kings, priestesses, and merchants to brickmakers, musicians, and weavers. Their habits of daily life, beliefs, triumphs, and crises, and the changes that people faced over time are explored through their own written words and the buildings, cities, and empires in which they lived.

David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. When his specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake, many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation.

In this partially autobiographical work, best-selling author Lewis Thomas offers insights on subjects as wide-ranging as gender differences, how it feels to be a patient, human vs. computer intelligence, the future of cancer research, and the longevity of the planet—interspersing all with charming anecdotes about his family, his colleagues and himself.

A forgotten, dark chapter of American history with implications for the current day, The Guarded Gate tells the story of the scientists who argued that certain nationalities were inherently inferior, providing the intellectual justification for the harshest immigration law in American history. Brandished by the upper-class Bostonians and New Yorkers - many of them progressives - who led the anti-immigration movement, the eugenic arguments helped keep hundreds of thousands of Jews, Italians, and other unwanted groups out of the US for more than 40 years.

The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

A century ago, everyone knew that people were fated by their race, sex, and nationality to be more or less intelligent, nurturing, or warlike. But Columbia University professor Franz Boas looked at the data and decided everyone was wrong. Racial categories, he insisted, were biological fictions. Cultures did not come in neat packages labeled "primitive" or "advanced". What counted as a family, a good meal, or even common sense was a product of history and circumstance, not of nature.

The Nobel laureate Otto Warburg was widely regarded in his day as one of the most important biochemists of the 20th century, a man whose research was integral to humanity’s understanding of cancer. He was also among the most despised figures in Nazi Germany. As a Jewish homosexual living openly with his male partner, Warburg represented all that the Third Reich abhorred. Yet Hitler and his top advisors dreaded cancer, and protected Warburg in the hope that he could cure it.

Tom Wolfe, whose legend began in journalism, takes us on an eye-opening journey that is sure to arouse widespread debate. The Kingdom of Speech is a captivating, paradigm-shifting argument that speech - not evolution - is responsible for humanity's complex societies and achievements.

Derek Parfit (1942–2017) is the most famous philosopher most people have never heard of. Widely regarded as one of the greatest moral thinkers of the past hundred years, Parfit was anything but a public intellectual. Yet his ideas have shaped the way philosophers think about things that affect us all: equality, altruism, what we owe to future generations, and even what it means to be a person. In Parfit, David Edmonds presents the first biography of an intriguing, obsessive, and eccentric genius.

If there is one belief that has united the left and the right, psychologists and philosophers, ancient thinkers and modern ones, it is the tacit assumption that humans are bad. It's a notion that drives newspaper headlines and guides the laws that shape our lives. From Machiavelli to Hobbes, Freud to Pinker, the roots of this belief have sunk deep into Western thought. Human beings, we're taught, are by nature selfish and governed primarily by self-interest.

From the creation of the first encyclopedia to Wikipedia, from ancient museums to modern kindergarten classes—this is Simon Winchester’s brilliant and all-encompassing look at how humans acquire, retain, and pass on information and data, and how technology continues to change our lives and our minds. Throughout this fascinating tour, Winchester forces us to ponder what rational humans are becoming. What good is all this knowledge if it leads to lack of thought? What is information without wisdom?

Norman Lebrecht has devoted half of his life to pondering and researching the mindset of the Jewish intellectuals, writers, scientists, and thinkers who turned the tides of history and shaped the world today as we know it. In Genius & Anxiety, Lebrecht begins with the Communist Manifesto in 1847 and ends in 1947, when Israel was founded. This robust, magnificent volume, beautifully designed, is an urgent and necessary celebration of Jewish genius and contribution.

Paul Dirac was among the great scientific geniuses of the modern age. One of the discoverers of quantum mechanics, the most revolutionary theory of the past century, his contributions had a unique insight, eloquence, clarity, and mathematical power. His prediction of antimatter was one of the greatest triumphs in the history of physics.

Bringing his audacious and persuasive thesis to life, Gartner offers case histories of some famous Americans who represent this phenomenon of hypomania. These are the real stories you never learned in school about some of those men who made America: Columbus, who discovered the continent, thought he was the messiah. John Winthrop, who settled and defined it, believed Americans were God's new chosen people. Alexander Hamilton, the indispensable founder who envisioned America's economic future, self-destructed because of pride and impulsive behavior.

Nine remarkable men produced inventions that changed the world. The printing press, the telephone, powered flight, recording and others have made the modern world what it is. But who were the men who had these ideas and made reality of them? As David Angus shows, they were very different - quiet, boisterous, confident, withdrawn - but all had a moment of vision allied to single-minded determination to battle through numerous prototypes and produced something that really worked. This is a fascinating account for younger listeners.

In 1875, tuberculosis was the deadliest disease in the world, accountable for a third of all deaths. A diagnosis of TB - often called consumption - was a death sentence. Then, in a triumph of medical science, a German doctor named Robert Koch deployed an unprecedented scientific rigor to discover the bacteria that caused TB. Koch soon embarked on a remedy - a remedy that would be his undoing. When Koch announced his cure for consumption, Arthur Conan Doyle, then a small-town doctor in England and sometime writer, went to Berlin to cover the event.

Few recognize how the Great War, the industrialized slaughter that bled Europe from 1914 to 1918, shaped Einstein’s life and work. While Einstein never held a rifle, he formulated general relativity blockaded in Berlin, literally starving. He lost 50 pounds in three months, unable to communicate with his most important colleagues. Some of those colleagues fought against rabid nationalism; others were busy inventing chemical warfare - scientists trapped in the power plays of empire. Meanwhile, Einstein struggled to craft relativity and persuade the world that it was correct.

In 2013, the New York Times published an obituary for Yvonne Brill. It began: “She made a mean beef stroganoff, followed her husband from job to job, and took eight years off from work to raise three children.” It wasn’t until the second paragraph that readers discovered why the Times had devoted several hundred words to her life: Brill was a brilliant rocket scientist who invented a propulsion system to keep communications satellites in orbit, and had recently been awarded the National Medal of Technology and Innovation.

It began with plutonium, the first element ever manufactured in quantity by humans. Fearing that the Germans would be the first to weaponize the atom, the United States marshaled brilliant minds and seemingly inexhaustible bodies to find a way to create a nuclear chain reaction of inconceivable explosive power. In a matter of months, the Hanford nuclear facility was built to produce and weaponize the enigmatic and deadly new material that would fuel atomic bombs.
