In April 1982, ethnobotanist Wade Davis arrived in Haiti to investigate two documented cases of zombies - people who had reappeared in Haitian society years after they had been officially declared dead and had been buried. Drawn into a netherworld of rituals and celebrations, Davis penetrated the vodoun mystique deeply enough to place zombification in its proper context within vodoun culture. In the course of his investigation, Davis came to realize that the story of vodoun is the history of Haiti.

A riveting investigation of the myriad ways that parasites control how other creatures - including humans - think, feel, and act. These tiny organisms can live only inside another animal, and, as McAuliffe reveals, they have many evolutionary motives for manipulating their host's behavior. Far more often than appreciated, these puppeteers orchestrate the interplay between predator and prey.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex. Eve is not only a sweeping revision of human history, it's an urgent and necessary corrective for a world that has focused primarily on the male body for far too long. Bohannon's findings will completely change what you think you know about evolution.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game.

Thought of as the seat of our soul, then as a mysteriously animated object, the heart is still more a mystery than it is understood. Why do most animals only get one billion beats? (And how did modern humans get to over two billion - effectively letting us live out two lives?) Why are sufferers of gingivitis more likely to have heart attacks? And what does it really feel like to touch your own heart, or to have someone else's beating inside your chest?

Today, we know more about mental health than ever before, but traditional medicine still mistakes subtle signs of trauma for stress, anxiety, or chronic disease—sometimes even retraumatizing patients with outdated and misguided methods. Treatment plans that focus on the mind are only addressing the downstream effects. Likewise, common medical approaches to manage symptoms fail to explore root causes and promote genuine recovery.

How did life begin? It is perhaps the most important question science has ever asked. Over the centuries, the search for an answer has been entwined with some of science's most revolutionary advances, including van Leeuwenhoek's microscope, Darwin's theory of evolution, and Crick and Watson's unveiling of DNA.

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.

Dame Sue Black is an internationally renowned forensic anthropologist and human anatomist. She has lived her life eye to eye with the Grim Reaper, and she writes vividly about it in this book, which is part primer on the basics of identifying human remains, part frank memoir of a woman whose first paying job as a schoolgirl was to apprentice in a butcher shop, and part no-nonsense but deeply humane introduction to the reality of death in our lives. It is a treat for CSI junkies, murder mystery and thriller fans, and anyone seeking a clear-eyed guide to a subject that touches us all.

The form and function of a sprinting cheetah are quite unlike those of a rooted tree. A human being is very different from a bacterium or a zebra. The living world is a realm of dazzling variety, yet a shared set of physical principles shapes the forms and behaviors of every creature in it. So Simple a Beginning shows how the emerging new science of biophysics is transforming our understanding of life on Earth and enabling potentially lifesaving but controversial technologies such as gene editing, artificial organ growth, and ecosystem engineering.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

The Nazis discovered it. The Allies won the war with it. It conquered diseases, changed laws, and single-handedly launched the era of antibiotics. This incredible discovery was sulfa, the first antibiotic medication. In The Demon Under the Microscope, Thomas Hager chronicles the dramatic history of the drug that shaped modern medicine.

Microbiology for Dummies is your guide to understanding the fundamentals of this enormously-encompassing field. Whether your career plans include microbiology or another science or health specialty, you need to understand life at the cellular level before you can understand anything on the macro scale. Microbes are literally the foundation of all life, and they are everywhere. Microbiology for Dummies will help you understand them, appreciate them, and use them.

Improbable Destinies will change the way we think and talk about evolution. Losos' insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

Most of us are aware of the hive mind—the power of bees as an amazing collective. But do we know how uniquely intelligent bees are as individuals? In The Mind of a Bee, Lars Chittka draws from decades of research, including his own pioneering work, to argue that bees have remarkable cognitive abilities. He shows that they are profoundly smart, have distinct personalities, can recognize flowers and human faces, exhibit basic emotions, count, use simple tools, solve problems, and learn by observing others. They may even possess consciousness.

An incredible 923 species from all of North America are included in this marvelous audio companion to the best-selling Stokes Field Guides.

Trouet, a leading tree-ring scientist, takes us out into the field, from remote African villages to radioactive Russian forests, offering listeners an insider's look at tree-ring research, a discipline formally known as dendrochronology. Tracing her own professional journey while exploring dendrochronology's history and applications, Trouet describes the basics of how tell-tale tree cores are collected and dated with ring-by-ring precision, explaining the unexpected and momentous insights we've gained from the resulting samples.
