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.

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.

Selected as a Non-Fiction Book of the Year New York Times Selected as a Science Book of the Year by The Economist, The Times and Observer 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.

A Sunday Times bestseller The key to living a happier, healthier life is inside us. Our gut is almost as important to us as our brain or our heart, yet we know very little about how it works. In Gut, Giulia Enders shows that rather than the utilitarian and — let’s be honest — somewhat embarrassing body part we imagine it to be, it is one of the most complex, important, and even miraculous parts of our anatomy. And scientists are only just discovering quite how much it has to offer; new research shows that gut bacteria can play a role in everything from obesity and allergies to Alzheimer’s. Beginning with the personal experience of illness that inspired her research, and going on to explain everything from the basics of nutrient absorption to the latest science linking bowel bacteria with depression, Enders has written an entertaining, informative health handbook. Gut definitely shows that we can all benefit from getting to know the wondrous world of our inner workings. In this charming book, young scientist Giulia Enders takes us on a fascinating tour of our insides. Her message is simple — if we treat our gut well, it will treat us well in return. But how do we do that? And why do we need to? Find out in this surprising, and surprisingly funny, exploration of the least understood of our organs.

The language of genes has become common parlance. We know they make your eyes blue, your hair curly or your nose straight. The media tells us that our genes control the risk of cancer, heart disease, alcoholism or Alzheimer's. The cost of DNA sequencing has plummeted from billions of pounds to a few hundred, and gene-based advances in medicine hold huge promise. So we've all heard of genes, but how do they actually work? There are 2.2 metres of DNA inside every one of your cells, encoding roughly 20,000 genes. These are the 'recipes' that tell our cells how to make the building blocks of life, along with myriad control switches ensuring they're turned on and off at the right time and in the right place. But rather than a static string of genetic code, this is a dynamic, writhing biological library. Figuring out how it all works Â? how your genes build your body Â? is a major challenge for researchers around the world. And what they're discovering is that far from genes being a fixed, deterministic blueprint, things are much more random and wobbly than anyone expected. Drawing on stories ranging from six toed cats and stickleback hips to Mickey Mouse mice and zombie genes Â? told by researchers working at the cutting edge of genetics Â? Kat Arney explores the mysteries in our genomes with clarity, flair and wit, creating a companion reader to the book of life itself.
