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 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.

Over the few short decades that followed Christopher Columbus' first landing in the Caribbean in 1492, Spain conquered the two most powerful civilizations of the Americas: the Aztecs of Mexico and the Incas of Peru. Hernán Cortés, Francisco Pizarro, and the other explorers and soldiers who took part in these expeditions dedicated their lives to seeking political and religious glory, helping to build an empire unlike any the world had ever seen. But centuries later, these conquistadors have become the stuff of nightmares.

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.

Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. But short of alien's landing in New York City, how do we know what they are like?

Over billions of years, ancient fish evolved to walk on land, reptiles transformed into birds that fly, and apelike primates evolved into humans that walk on two legs, talk, and write. For more than a century, paleontologists have traveled the globe to find fossils that show how such changes have happened.

It is widely understood that Charles Darwin’s theory of evolution completely revolutionized the study of biology. Yet, according to David Sloan Wilson, the Darwinian revolution won’t be truly complete until it is applied more broadly - to everything associated with the words “human,” “culture,” and “policy.”

Why do minds exist? How did mud and stone develop into beings that can experience longing, regret, love, and compassion - beings that are aware of their own experience? Until recently, science offered few answers to these existential questions. Journey of the Mind is the first book to offer a unified account of the mind that explains how consciousness, language, the Self, and civilization emerged incrementally out of chaos.

The year is 1919. The horror of the First World War is fresh for the protagonists of Time of the Magicians, each of whom finds himself at a crucial juncture. Benjamin is trying to flee his overbearing father and floundering in his academic career, living hand to mouth as a critic. Wittgenstein, by contrast, has dramatically decided to divest himself of the monumental fortune he stands to inherit, in search of spiritual clarity.

As Mark Mazower shows us in his enthralling and definitive new account, myths about the Greek War of Independence outpaced the facts from the very beginning, and for good reason. This was an unlikely cause, against long odds, a disorganized collection of Greek patriots up against what was still one of the most storied empires in the world, the Ottomans. The revolutionaries needed all the help they could get.

"There is the mammal way and there is the bird way." But the bird way is much more than a unique pattern of brain wiring, and lately, scientists have taken a new look at bird behaviors they have, for years, dismissed as anomalies or mysteries - what they are finding is upending the traditional view of how birds conduct their lives, how they communicate, forage, court, breed, survive. They are also revealing the remarkable intelligence underlying these activities, abilities we once considered uniquely our own.

The foundations of modern knowledge - philosophy, math, astronomy, geography - were laid by the Greeks, whose ideas were written on scrolls and stored in libraries across the Mediterranean and beyond. But as the vast Roman Empire disintegrated, so did appreciation of these precious texts. Christianity cast a shadow over so-called pagan thought, books were burned, and the library of Alexandria, the greatest repository of classical knowledge, was destroyed. Yet some texts did survive and The Map of Knowledge explores the role played by seven cities around the Mediterranean....

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.

Insects might make us recoil in repugnance, but they also manufacture - or make possible in other ways - many of the things we take for granted in our daily lives. When we bite into a shiny apple, listen to the resonant notes of a violin, try on the latest fashions, receive a dental implant, or get a manicure, we are mingling with the by-products of their everyday lives.

From its terrifying opening to its final eloquent words, Dispatches makes us see, in unforgettable and unflinching detail, the chaos and fervor of the war and the surreal insanity of life in that singular combat zone. Michael Herr’s unsparing, unorthodox retellings of the day-to-day events in Vietnam take on the force of poetry, rendering clarity from one of the most incomprehensible and nightmarish events of our time.
