In fact, a plethora of parasites affect our behavior in ways we have barely begun to understand.  In this mind-bending book, McAuliffe reveals the eons-old war between parasites and other creatures that is playing out in our very own bodies. And more surprising still, she uncovers the decisive role that parasites may have played in the rise and demise of entire civilizations. Our obsession with cleanliness and our experience of disgust are both evolutionary tools for avoiding infection, but they evolved differently for different populations. Political, social, and religious differences among societies may be caused, in part, by the different parasites that prey on us. 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.

    After five years of extensive research involving thousands of people who have pets and work with animals, Dr. Sheldrake proves conclusively what many pet owners already know: there is a strong connection between humans and animals that defies present-day scientific understanding. This remarkable book deserves a place next to the most beloved and valuable books on animals, including When Elephants Weep, Dogs Never Lie About Love, and The Hidden Life of Dogs.

    With his trademark humor and frankness, Alan Alda explains what makes the out-of-the-box techniques he developed after his years as the host of Scientific American Frontiers so effective. This book reveals what it means to be a true communicator, and how we can communicate better, in every aspect of our lives—with our friends, lovers, and families, with our doctors, in business settings, and beyond.

    Those who kill sheltered animals on the other. Can't we all just get along? Irreconcilable Differences says we can't because shelters act in ways which are the antithesis of the values most Americans hold dear. We are a nation of animal lovers. But the shelters we expect to save animals are instead needlessly killing about four million of them every year. Thankfully, animal lovers all over the U.S. are increasingly rejecting the excuses and blame shifting of shelter administrators used to justify that killing. And it is that rejection of the status quo, propelled by the American public's great love of companion animals, which is explored in this book's essays.

    Shipler makes clear in this powerful, humane study, the invisible poor are engaged in the activity most respected in American ideology—hard, honest work. But their version of the American Dream is a nightmare: low-paying, dead-end jobs; the profound failure of government to improve upon decaying housing, health care, and education; the failure of families to break the patterns of child abuse and substance abuse. Shipler exposes the interlocking problems by taking us into the sorrowful, infuriating, courageous lives of the poor—white and black, Asian and Latino, citizens and immigrants. We encounter them every day, for they do jobs essential to the American economy.We meet drifting farmworkers in North Carolina, exploited garment workers in New Hampshire, illegal immigrants trapped in the steaming kitchens of Los Angeles restaurants, addicts who struggle into productive work from the cruel streets of the nation's capital—each life another aspect of a confounding, far-reaching urgent national crisis. And unlike mostworks on poverty, this one delves into the calculations of some employers as well—their razor-thin profits, their anxieties about competition from abroad, their frustrations in finding qualified workers.This impassioned book not only dissects the problems, but makes pointed, informed recommendations for change. It is a book that stands to make a difference.
