A riveting investigation of the myriad ways that parasites control how other creatures—including humans—think, feel, and act. These tiny organisms can only live 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. With astonishing precision, parasites can coax rats to approach cats, spiders to transform the patterns of their webs, and fish to draw the attention of birds that then swoop down to feast on them. We humans are hardly immune to the profound influence of parasites. Organisms we pick up from our own pets are strongly suspected of changing our personality traits and contributing to recklessness, impulsivity—even suicide. Microbes in our gut affect our emotions and the very wiring of our brains. Germs that cause colds and flu may alter our behavior even before symptoms become apparent. Parasites influence our species on the cultural level too. As McAuliffe documents, a subconscious fear of contagion impacts virtually every aspect of our lives, from our sexual attractions and social circles to our morals and political views. Drawing on a huge body of research, she argues that our dread of contamination is an evolved defense against parasites—and a double-edged sword. The horror and revulsion we feel when we come in contact with people who appear diseased or dirty helped pave the way for civilization, but may also be the basis for major divisions in societies that persist to this day. In the tradition of Jared Diamond’s Guns, Germs and Steel and Neil Shubin’s Your Inner Fish, This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human.

NEW YORK TIMES BESTSELLER Your body is teeming with tens of trillions of microbes. It’s an entire world, a colony full of life. In other words, you contain multitudes. These microscopic companions sculpt our organs, protect us from diseases, guide our behaviour, and bombard us with their genes. They also hold the key to understanding all life on earth. In I Contain Multitudes, Ed Yong opens our eyes and invites us to marvel at ourselves and other animals in a new light, less as individuals and more as thriving ecosystems. We learn the invisible and wondrous science behind the corals that construct mighty reefs and the squid that create their own light shows. We see how bacteria can alter our response to cancer-fighting drugs, tune our immune system, influence our evolution, and even modify our genetic make-up. And we meet the scientists who are manipulating these microscopic partners to our advantage. In a million tiny ways, I Contain Multitudes will radically change how you think about the natural world, and how you see yourself.

"Eyeopening... Fascinating... may presage a paradigm shift in medicine. "Kirkus Reviews"(starred review) "Teeming with information and big ideas...Outstanding. "Booklist"(starred review) The origin of asthma, autism, Alzheimer's, allergies, cancer, heart disease, obesity, and even some kinds of depression is now clear. Award-winning researcher on the microbiome, professor Rodney Dietert presents a new paradigm in human biology that has emerged in the midst of the ongoing global epidemic of noncommunicable diseases. "The Human Superorganism"makes a sweeping, paradigm-shifting argument. It demolishes two fundamental beliefs that have blinkered all medical thinking until very recently: 1) Humans are better off as pure organisms free of foreign microbes; and 2) the human genome is the key to future medical advances. The microorganisms that we have sought to eliminate have been there for centuries supporting our ancestors. They comprise as much as 90 percent of the cells in and on our bodies a staggering percentage! More than a thousand species of them live inside us, on our skin, and on our very eyelashes. Yet we have now significantly reduced their power and in doing so have sparked an epidemic of noncommunicable diseases which now account for 63 percent of all human deaths. Ultimately, this book is not just about microbes; it is about a different way to view humans. The story that Dietert tells of where the new biology comes from, how it works, and the ways in which it affects your life is fascinating, authoritative, and revolutionary. Dietert identifies foods that best serve you, the superorganism; not new fad foods but ancient foods that have made sense for millennia. He explains protective measures against unsafe chemicals and drugs. He offers an empowering self-care guide and the blueprint for a revolution in public health. We are not what we have been taught. Each of us is a superorganism. The best path to a healthy life is through recognizing that profound truth."

Do fishes think? Do they really have three-second memories? And can they recognize the humans who peer back at them from above the surface of the water? In What a Fish Knows, the myth-busting ethologist Jonathan Balcombe addresses these questions and more, taking us under the sea, through streams and estuaries, and to the other side of the aquarium glass to reveal the surprising capabilities of fishes. Although there are more than thirty thousand species of fish—more than all mammals, birds, reptiles, and amphibians combined—we rarely consider how individual fishes think, feel, and behave. Balcombe upends our assumptions about fishes, portraying them not as unfeeling, dead-eyed feeding machines but as sentient, aware, social, and even Machiavellian—in other words, much like us. What a Fish Knows draws on the latest science to present a fresh look at these remarkable creatures in all their breathtaking diversity and beauty. Fishes conduct elaborate courtship rituals and develop lifelong bonds with shoalmates. They also plan, hunt cooperatively, use tools, curry favor, deceive one another, and punish wrongdoers. We may imagine that fishes lead simple, fleeting lives—a mode of existence that boils down to a place on the food chain, rote spawning, and lots of aimless swimming. But, as Balcombe demonstrates, the truth is far richer and more complex, worthy of the grandest social novel. Highlighting breakthrough discoveries from fish enthusiasts and scientists around the world and pondering his own encounters with fishes, Balcombe examines the fascinating means by which fishes gain knowledge of the places they inhabit, from shallow tide pools to the deepest reaches of the ocean. Teeming with insights and exciting discoveries, What a Fish Knows offers a thoughtful appraisal of our relationships with fishes and inspires us to take a more enlightened view of the planet’s increasingly imperiled marine life. What a Fish Knows will forever change how we see our aquatic cousins—the pet goldfish included.

A thrilling tale of encounters with nature’s masters of biochemistry From the coasts of Indonesia to the rainforests of Peru, venomous animals are everywhere—and often lurking out of sight. Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world. Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out. Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated. Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

Combining cutting-edge neuroscience with the latest discoveries on the human microbiome, a practical guide in the tradition of Wheat Belly and Grain Brain that conclusively demonstrates the inextricable, biological link between mind and body. We have all experienced the connection between our mind and our gut—the decision we made because it “felt right”; the butterflies in our stomach before a big meeting; the anxious stomach rumbling when we’re stressed out. While the dialogue between the gut and the brain has been recognized by ancient healing traditions, including Ayurvedic and Chinese medicine, Western medicine has failed to appreciate the complexity of how the brain, gut, and more recently, the microbiome—the microorganisms that live inside us—communicate with one another. In The Mind-Gut Connection, Dr. Emeran Mayer, executive director of the UCLA Center for Neurobiology of Stress, offers a revolutionary look at this developing science, teaching us how to harness the power of the mind-gut connection to take charge of our health. The Mind-Gut Connection shows how to keep the brain-gut communication clear and balanced to: • heal the gut by focusing on a plant-based diet • balance the microbiome by consuming fermented foods and probiotics, fasting, and cutting out sugar and processed foods • promote weight loss by detoxifying and creating healthy digestion and maximum nutrient absorption • boost immunity and prevent the onset of neurological diseases such as Parkinson’s and Alzheimer’s • generate a happier mindset and reduce fatigue, moodiness, anxiety, and depression • prevent and heal GI disorders such as leaky gut syndrome, food sensitivities and allergies, and IBS, as well as digestive discomfort such as heartburn and bloating • and much more.
