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.

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.
