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.

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.Now, in this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves in to everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

The range of environments in which people can survive is extensive, yet most of the natural world cannot support human life. The Biology of Human Survival identifies the key determinants of life or death in extreme environments from a physiologist's perspective, integrating modern concepts of stress, tolerance, and adaptation into explanations of life under Nature's most austere conditions. The book examines how individuals survive when faced with extremes of immersion, heat, cold or altitude, emphasizing the body's recognition of stress and the brain's role in optimizing physiological function in order to provide time to escape or to adapt. In illustrating how human biology adapts to extremes, the book also explains how we learn to cope by blending behavior and biology, first by trial and error, then by rigorous scientific observation, and finally by technological innovation. The book describes life-support technology and how it enables humans to enter once unendurable realm, from the depths of the ocean to the upper reaches of the atmosphere and beyond. Finally, it explores the role that advanced technology might play in special environments of the future, such as long journeys into space.

A candid, feminist, and personal deep dive into the science and culture of pregnancy and motherhoodLike most first-time mothers, Angela Garbes was filled with questions when she became pregnant. What exactly is a placenta and how does it function? How does a body go into labor? Why is breast best? Is wine totally off-limits? But as she soon discovered, it’s not easy to find satisfying answers. Your obstetrician will cautiously quote statistics; online sources will scare you with conflicting and often inaccurate data; and even the most trusted books will offer information with a heavy dose of judgment. To educate herself, the food and culture writer embarked on an intensive journey of exploration, diving into the scientific mysteries and cultural attitudes that surround motherhood to find answers to questions that had only previously been given in the form of advice about what women ought to do—rather than allowing them the freedom to choose the right path for themselves.In Like a Mother, Garbes offers a rigorously researched and compelling look at the physiology, biology, and psychology of pregnancy and motherhood, informed by in-depth reportage and personal experience. With the curiosity of a journalist, the perspective of a feminist, and the intimacy and urgency of a mother, she explores the emerging science behind the pressing questions women have about everything from miscarriage to complicated labors to postpartum changes. The result is a visceral, full-frontal look at what’s really happening during those nine life-altering months, and why women deserve access to better care, support, and information.Infused with humor and born out of awe, appreciation, and understanding of the female body and its strength, Like a Mother debunks common myths and dated assumptions, offering guidance and camaraderie to women navigating one of the biggest and most profound changes in their lives.

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.

Evolutionary thinking provides insights into many different areas in the research and practice of medicine and public health. It takes specialties such as medical microbiology, epidemiology, oncology, gynecology, and psychiatry that had become increasingly siloed and places them in a larger framework. This foundational structure enables students to view medical knowledge as an integrated whole, underpinned by general principles rather than a loose collection of disparate facts. The discipline of evolutionary medicine continues to advance rapidly as new results come in showing where the insights pay off and where they do not. Its conceptual foundations have also been strengthened in papers not yet reflected in the textbooks, so a new edition is therefore timely. At the same time, the teaching of evolutionary medicine has also been steadily gaining momentum both in courses that prepare undergraduates for medical school in North America and in other contexts worldwide. Evolutionary Medicine is intended for undergraduate students preparing for careers in medicine and public health, students in schools of medicine and public health, and medical professionals curious about the insights that evolutionary thinking can bring to their field. It will also be relevant to students and researchers in the fields of evolutionary biology, anthropology, developmental biology, and genetics. It highlights the most important insights in a relatively brief and compelling book that does not attempt encyclopedic coverage of a rapidly changing field.
