While some books explore our genetic inheritance and popular television shows celebrate ancestry, this is the first book to explore how everything from DNA to emotions to names and the stories that form our lives are all part of our human legacy. This book shows how trust is inherited in Africa, silence is passed down in Tasmania, and how the history of nations is written in our DNA. From fateful, ancient encounters to modern mass migrations and medical diagnoses, Kenneally explains how the forces that shaped the history of the world ultimately shape each human who inhabits it. The Invisible History of the Human Race is a deeply researched, carefully crafted, and provocative perspective on how our stories, psychology, and genetics affect our past and our future.

    Within a few short decades the most hostile of the world’s environments had all been conquered. Likewise, in the twentieth century, medicine transformed human life. Doctors took what was routinely fatal and made it survivable. As modernity brought us ever more into different kinds of extremis, doctors pushed the bounds of medical advances and human endurance. Extreme exploration challenged the body in ways that only the vanguard of science could answer. Doctors, scientists, and explorers all share a defining trait: they push on in the face of grim odds. Because of their extreme exploration we not only understand our physiology better; we have also made enormous strides in the science of healing.Drawing on his own experience as an anesthesiologist, intensive care expert, and NASA adviser, Dr. Kevin Fong examines how cuttingedge medicine pushes the envelope of human survival by studying the human body’s response when tested by physical extremes. Extreme Medicine explores different limits of endurance and the lens each offers on one of the systems of the body. The challenges of Arctic exploration created opportunities for breakthroughs in open heart surgery; battlefield doctors pioneered techniques for skin grafts, heart surgery, and trauma care; underwater and outer space exploration have revolutionized our understanding of breathing, gravity, and much more. Avant-garde medicine is fundamentally changing our ideas about the nature of life and death.Through astonishing accounts of extraordinary events and pioneering medicine, Fong illustrates the sheer audacity of medical practice at extreme limits, where human life is balanced on a knife’s edge. Extreme Medicine is a gripping debut about the science of healing, but also about exploration in its broadest sense—and about how, by probing the very limits of our biology, we may ultimately return with a better appreciation of how our bodies work, of what life is, and what it means to be human.

    Poisons permeate our world. They are in the environment, the workplace, the home. They are in food, our favorite whiskey, medicine, well water. They have been used to cure disease as well as to incapacitate and kill. They smooth wrinkles, block pain, stimulate, and enhance athletic ability. In this entertaining and fact-filled book, science writer Peter Macinnis considers poisons in all their aspects. He recounts stories of the celebrated poisoners in history and literature, from Nero to Thomas Wainewright, and from the death of Socrates to Hamlet and Peter Pan. He discusses the sources of various poisons-from cyanide to strychnine, from Botox to ricin and Sarin gas-as well as their detection. Then he analyzes the science of their action in the body and their uses in medicine, cosmetics, war, and terrorism. With wit and precision, he weighs such questions as: Was Lincoln's volatility caused by mercury poisoning? Was Jack the Ripper an arsenic eater? Can wallpaper kill? For anyone who has ever wondered and been afraid to ask, here is a rich miscellany for your secret questions about toxins.
