"Ants are the most warlike of all animals, with colony pitted against colony.... Their clashes dwarf Waterloo and Gettysburg", writes Edward O. Wilson in his most finely observed work in decades. In a myrmecological tour to such far-flung destinations as Mozambique and New Guinea, the Gulf of Mexico's Dauphin Island and even his parents' overgrown yard back in Alabama, Wilson thrillingly evokes his nine-decade-long scientific obsession with more than 15,000 ant species.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Locked in the silence and darkness of your skull, your brain fashions the rich narratives of your reality and your identity. Join renowned neuroscientist David Eagleman for a journey into the questions at the mysterious heart of our existence. What is reality? Who are “you”? How do you make decisions? Why does your brain need other people? How is technology poised to change what it means to be human?

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

Every one of us contains a billion times more atoms than all the grains of sand in the earth’s deserts. If you weigh 150 pounds, you’ve got enough carbon to make 25 pounds of charcoal, enough salt to fill a saltshaker, enough chlorine to disinfect several backyard swimming pools, and enough iron to forge a 3-inch nail. But how did these elements combine to make us human?

Microscopic organisms are as important to plant growth as water and light. Microbe Science for Gardeners highlights the essential role of microbes in plant biosystems and soil health, provides practical how-to gardening advice for enhancing plant microbiomes, and debunks common gardening myths.

In this Very Short Introduction audiobook, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

Most of us think that longevity hinges on maintaining a normal Body Mass Index. But research conducted over the last decade hit the media in January with explosive news: Overweight and even moderately obese people with certain chronic diseases - from heart disease to cancer - often live longer and fare better than normal-weight individuals with the same ailments. In this groundbreaking audiobook, Carl Lavie, MD, reveals the science behind the obesity paradox and shows us how to achieve maximum health rather than minimum weight.

At every moment, within our bodies and all around us, trillions of microscopic combatants are waging a war that shapes our health and life on Earth. Countless times per second, viruses known as phages attack and destroy bacteria while leaving all other life forms, including us, unscathed. Vastly outnumbering the viruses that do us harm, phages power ecosystems, drive evolutionary innovation, and harbor a remarkable capacity to heal life-threatening infections when conventional antibiotics fail. Yet most of us have never heard of them, thinking of viruses only as enemies to be feared.

Birds are astonishingly intelligent creatures. According to revolutionary new research, some birds rival primates and even humans in their remarkable forms of intelligence. In The Genius of Birds, acclaimed author Jennifer Ackerman explores their newly discovered brilliance and how it came about. As she travels around the world to the most cutting-edge frontiers of research, Ackerman not only tells the story of the recently uncovered genius of birds but also delves deeply into the latest findings about the bird brain itself that are shifting our view of what it means to be intelligent.

Joining the ranks of popular science classics like The Botany of Desire and The Selfish Gene, a groundbreaking, wondrously informative, and vastly entertaining examination of the most significant revolution in biology since Darwin - a "microbe's-eye view" of the world that reveals a marvelous, radically reconceived picture of life on Earth.

Have you ever wondered what your dogs are thinking? What they're feeling? Now you can finally know! The answers will surprise and delight you as scientist and dog owner Alexandra Horowitz explains how our four-legged friends perceive their daily worlds, each other, and that other quirky animal, the human.

A deft mixture of memoir and history, modern biology and behavior, In Search of Memory brings listeners from Kandel's childhood in Nazi-occupied Vienna to the forefront of one of the great scientific endeavors of the 20th century: the search for the biological basis of memory. Nobel Prize winner Eric R. Kandel intertwines the intellectual history of the powerful new science of the mind - a combination of cognitive psychology, neuroscience, and molecular biology - with his own personal quest to understand memory.

In this mesmerizing account, Sy Montgomery passionately and vividly reveals the wonderous world of hawks and what they can teach us about nature, life, and love.

We are facing an overwhelming army of deadly, invisible enemies. We need a plan - before it's too late. Unlike natural disasters, whose destruction is concentrated in a limited area over a period of days, and illnesses, which have devastating effects but are limited to individuals and their families, infectious disease has the terrifying power to disrupt everyday life on a global scale, overwhelming public and private resources and bringing trade and transportation to a grinding halt.

As one of the most beautiful and intriguing birds found in nature, hummingbirds fascinate people around the world. The lightest birds in the sky, hummingbirds are capable of incredible feats, such as flying backwards, diving at speeds of 61 MPH, and beating their wings more than 60 times a second. Miraculous creatures, they are also incredibly vulnerable when they first emerge from their eggs. That’s where Brenda Sherburn comes in. With tenderness and patience, she rescues abandoned hummingbirds and nurses them back to health until they can fly away and live in the wild.

In the 200 years since we discovered that microbes cause infectious diseases, we've battled to keep them at bay. But a recent explosion of scientific knowledge has led to undeniable evidence that early exposure to these organisms is beneficial to our children's well-being. Our current emphasis on hyper-cleanliness is taking a toll on our children's lifelong health. This engaging and important book explains how the millions of microbes that live in our bodies influence childhood development.

All of us would like to live longer, or to slow the debilitating effects of age. In How We Age, Coleen Murphy shows how recent research on longevity and aging may be bringing us closer to this goal. Murphy, a leading scholar of aging, explains that the study of model systems, particularly simple invertebrate animals, combined with breakthroughs in genomic methods, have allowed scientists to probe the molecular mechanisms of longevity and aging.

First coined by Richard Dawkins in The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation. Susan Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive-making tools, for example, or using language - survived and flourished, replicating themselves in as many minds as possible.
