If it weren't for mitochondria, scientists argue, we'd all still be single-celled bacteria. Indeed, these tiny structures inside our cells are important beyond imagining. Without mitochondria, we would have no cell suicide, no sculpting of embryonic shape, no sexes, no menopause, no aging.In this fascinating and thought-provoking book, Nick Lane brings together the latest research in this exciting field to show how our growing insight into mitochondria has shed light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. These findings are of fundamental importance, both in understanding life on Earth, but also in controlling our own illnesses, and delaying our degeneration and death. Readers learn that two billion years ago, mitochondria were probably bacteria living independent lives and that their capture within larger cells was a turning point in the evolution of life, enabling the development of complex organisms. Lane describes how mitochondria have their own DNA and that its genes mutate much faster than those in the nucleus. This high mutation rate lies behind our aging and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer. We also discover that mitochondrial DNA is passed down almost exclusively via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to "Mitochondrial Eve," giving us vital information about our evolutionary history.Written by Nick Lane, a rising star in popular science, Power, Sex, Suicide is the first book for general readers on the nature and function of these tiny, yet fascinating structures.

In this landmark book of popular science, Daniel E. Lieberman—chair of the department of human evolutionary biology at Harvard University and a leader in the field—gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease.   The Story of the Human Body brilliantly illuminates as never before the major transformations that contributed key adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and gathering, leading to our superlative endurance athleticism; the development of a very large brain; and the incipience of cultural proficiencies. Lieberman also elucidates how cultural evolution differs from biological evolution, and how our bodies were further transformed during the Agricultural and Industrial Revolutions.   While these ongoing changes have brought about many benefits, they have also created conditions to which our bodies are not entirely adapted, Lieberman argues, resulting in the growing incidence of obesity and new but avoidable diseases, such as type 2 diabetes. Lieberman proposes that many of these chronic illnesses persist and in some cases are intensifying because of “dysevolution,” a pernicious dynamic whereby only the symptoms rather than the causes of these maladies are treated. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes even compel us to create a more salubrious environment.

award winning science writer examines cancer with a cellular biologist's precision

Gold Award Winner, 2024 Nonfiction Book Awards Runner-up, 2024 History category, San Francisco Book Festival Runner-up, 2024 General Non-Fiction, New York Book Festival For much of recorded history, people considered the heart to be the most important organ in the body. In cultures around the world, the heart—not the brain—was believed to be the location of intelligence, memory, emotion, and the soul. Over time, views on the purpose of the heart have transformed as people sought to understand the life forces it contains. Modern medicine and science dismissed what was once the king of the organs as a mere blood pump subservient to the brain, yet the heart remains a potent symbol of love and health and an important part of our cultural iconography. This book traces the evolution of our understanding of the heart from the dawn of civilization to the present. Vincent M. Figueredo—an accomplished cardiologist and expert on the history of the human heart—explores the role and significance of the heart in art, culture, religion, philosophy, and science across time and place. He examines how the heart really works, its many meanings in our emotional and daily lives, and what cutting-edge science is teaching us about this remarkable organ. Figueredo considers the science of heart disease, recent advancements in heart therapies, and what the future may hold. He highlights the emerging field of neurocardiology, which has found evidence of a “heart-brain connection” in mental and physical health, suggesting that ancient views hold more truth than moderns suspect. Ranging widely and deeply throughout human history, this book sheds new light on why the heart remains so central to our sense of self.

Susan Sontag's celebrated essays on cancer and AIDS now available in one volume.In 1978, Sontag wrote Illness as Metaphor, a classic work described by Newsweek as "one of the most liberating books of its time." A cancer patient herself when she was writing the book, Sontag shows how the metaphors and myths surrounding certain illnesses, especially cancer, add greatly to the suffering of patients and often inhibit them from seeking proper treatment. By demystifying the fantasies surrounding cancer, Sontag shows cancer for what it is--just a disease. Cancer, she argues, is not a curse, not a punishment, certainly not an embarrassment and, it is highly curable, if good treatment is followed.Almost a decade later, with the outbreak of a new, stigmatized disease replete with mystifications and punitive metaphors, Sontag wrote a sequel to Illness as Metaphor, extending the argument of the earlier book to the AIDS pandemic.These two essays now published together, Illness as Metaphor and AIDS and Its Metaphors, have been translated into many languages and continue to have an enormous influence on the thinking of medical professionals and, above all, on the lives of many thousands of patients and caregivers.

The real crisis in medicine today is not about economics, insurance, or managed care--it's about the loss of the fundamental human relationship between doctor and patient. In this wise and passionate book, one of our most eminent physicians reacquaints us with a classic notion often overlooked in modern medicine: health care with a human face, in which the time-honored art of healing guides doctors in their approach to patient care and their use of medical technology.Drawing on four decades of practice as a cardiologist and a vast knowledge of literature and medical history, Dr. Lown probes the heart and soul of the doctor-patient relationship. Insightful and accessible to all, The Lost Art of Healing describes how true healers use sympathetic listening and touch to hone their diagnostic skills, how language affects the perception of illness, how doctors and patients can cultivate a relationship of trust, and how patients can obtain the most complete and beneficial care through a combination of healing techniques and conventional practices.As Dr. Lown explains, the art of healing does not mean abandoning the spectacular advances of modern science, but rather incorporating them into a sensitive, humane, enlightened approach to medical care. With its urgent message and poignant, fascinating vignettes, The Lost Art of Healing is a book of vital, universal importance.

“Overdosed America reveals the greed and corruption that drive health care costs skyward and now threaten the public health. Before you see a doctor, you should read this book.” —Eric Schlosser, author of Fast Food Nation Using the examples of Vioxx, Celebrex, cholesterol-lowering statin drugs, and anti-depressants, Overdosed America shows that at the heart of the current crisis in American medicine lies the commercialization of medical knowledge itself For twenty years, John Abramson, M.D., cared for patients of all ages in a small town north of Boston. But increasingly his role as family doctor was undermined as pressure mounted to use the latest drugs and high-tech solutions for nearly every problem. Drawing on his background in statistics and health policy research, he began to investigate the radical changes that were quietly taking place in American medicine. At the heart of the crisis, he found, lies the changed purpose of medical knowledge—from seeking to optimize health to searching for the greatest profits. The lack of transparency that has become normal in commercially sponsored medical research now taints the scientific evidence published in even our most prestigious medical journals. And unlike the recent scandals in other industries that robbed Americans of money and jobs, this one is undermining our health. Commercial distortion pervades the information that doctors rely upon to guide the prevention and treatment of common health problems, from heart disease to stroke, osteoporosis, diabetes, and osteoarthritis. The good news, as Dr. Abramson explains, is that the real scientific evidence shows that many of the things that you can do to protect and preserve your own health are far more effective than what the drug companies' top-selling products can do for you—which is why the drug companies work so hard to keep this information under wraps. In what is sure to be one of the most important and eye-opening books you or your doctor will ever read, John Abramson offers conclusive evidence that American medicine has broken its promise to best improve our health and is squandering more than $500 billion each year in the process.

Author of the international bestsellers The Diabetes Code and The Obesity Code Dr. Jason Fung returns with an eye-opening biography of cancer in which he offers a radical new paradigm for understanding cancer—and issues a call to action for reducing risk moving forward. Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline . . . but the “War on Cancer” has hardly been won. In The Cancer Code, Dr. Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease—what it is, how it manifests, and why it is so challenging to treat. In this rousing narrative, Dr. Fung identifies the medical community’s many missteps in cancer research—in particular, its focus on genetics, or what he terms the “seed” of cancer, at the expense of examining the “soil,” or the conditions under which cancer flourishes. Dr. Fung—whose groundbreaking work in the treatment of obesity and diabetes has won him international acclaim—suggests that the primary disease pathway of cancer is caused by the dysregulation of insulin. In fact, obesity and type 2 diabetes significantly increase an individual’s risk of cancer. In this accessible read, Dr. Fung provides a new paradigm for dealing with cancer, with recommendations for what we can do to create a hostile soil for this dangerous seed. One such strategy is intermittent fasting, which reduces blood glucose, lowering insulin levels. Another, eliminating intake of insulin-stimulating foods, such as sugar and refined carbohydrates. For hundreds of years, cancer has been portrayed as a foreign invader we’ve been powerless to stop. By reshaping our view of cancer as an internal uprising of our own healthy cells, we can begin to take back control. The seed of cancer may exist in all of us, but the power to change the soil is in our hands.
