    In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    Revised to reflect the latest research in the field, this book emphasizes the relationships and concepts that link cell and tissue structures with their functions.

    Leeuwenhoek proceeded to examine the microscopic activity of his spittle, teeth plaque, and feces, and as the result of his findings the field of bacteriology was born. Some two hundred years later, Wilhelm Conrad Roentgen, a professor of theoretical physics at the University of Wurzburg, invited his wife to his laboratory, asked her to place her hand on an unexposed photographic plate, turned on an electric current, and showed this terrified woman a picture of the bones of her hand. And so came the discovery of the X-ray.This absorbing book is the first to describe these and eight other monumental medical discoveries throughout history, bringing to life the scientific pioneers responsible for them and the excitement, frustrations, and jealousies that surrounded the final achievements. Two distinguished physicians, Meyer Friedman and Gerald W. Friedland, have drawn on their many years of experience as well as on that of world-renowned antiquarian book dealers, physician collectors of old and new medical publications, and medical school professors to single out these medical breakthroughs from thousands of candidates, and, in several cases, to provide information never before available. Their engrossing stories of the ten most significant discoveries will be read with enjoyment by anyone fascinated by the mysteries of medicine.

    The book features case discussions, USMLE-style questions, and a USMLE-style practice exam.

    In this edition the authors have created a learning system that makes the chapters easier to navigate and provides a variety of ways for students to learn the material. "Learning Objectives" are now strategically placed throughout the chapter following major headings, and there are review questions at the ends of these major sections. "Chapter Summaries" are now organized around the "Learning Objectives" as well, making it easier for students to return to the place in the book that can help them work through the end-of-chapter material. Icons throughout the chapter direct students to the BiologyNow CD and tells them what they will find there. BiologyNow, the new Student CD-ROM for BIOLOGY Seventh Edition, is also based on these "Learning Objectives" to further reinforce the text's concepts. The BiologyNow CD, fully integrated with the Seventh Edition text, provides access to diagnostic pre-tests for each chapter. It also automatically generates customized learning plans for students, directing students to the information in the book, ancillaries and media program that will help them master specific concepts. Post-tests allow students to assess their progress as well. Personal Tutor with SMARTHINKING, a FREE online live tutoring service. Students can ask questions, get answers, and they don't need to set up appointments! For instructors, a Multimedia Manager provides the text art in PowerPoint form. Instructors also receive an Instructor's Guide, ExamView Electronic Testing and WebTutor course management options. Solomon, Berg, and Martin have gone beyond presenting facts for memorization -- they have created a well-designed pedagogical system through their use and reuse of chapter "Learning Objectives," which is supported by an unbelievable package of materials for instructors and students.

    In this delightful and compelling exploration of our most neglected sense, veteran science reporter Bob Holmes shows us just how much we’re missing.Considering every angle of flavor from our neurobiology to the science and practice of modern food production, Holmes takes readers on a journey to uncover the broad range of factors that can affect our appreciation of a fine meal or an exceptional glass of wine. He peers over the shoulders of some of the most fascinating food professionals working today, from cutting-edge chefs to food engineers to mathematicians investigating the perfect combination of pizza toppings. He talks with flavor and olfactory scientists, who describe why two people can experience remarkably different sensations from the same morsel of food, and how something as seemingly unrelated as cultural heritage can actually impact our sense of smell.Along the way, even more surprising facts are revealed: that cake tastes sweetest on white plates; that wine experts’ eyes can fool their noses; and even that language can affect our sense of taste. Flavor expands our curiosity and understanding of one of our most intimate sensations, while ultimately revealing how we can all sharpen our senses and our enjoyment of the things we taste.Certain to fascinate everyone from gourmands and scientists to home cooks and their guests, Flavor will open your mind—and palette—to a vast, exciting sensory world.

    

    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.
