Animal cells present an extreme variability in their shapes in relation to their physiological properties. For instance, fibroblastic cells are tightly attached to the extra-cellular matrix and display a flattened, spindle-shaped morphology. Neuronal cells self-organize as a network through a complex branching of dendrites and a long axonal extension. Resting peripheral blood lymphocytes are poorly adhesive and maintain a spherical, smooth shape, while macroph- ages produce many pseudopodal extensions involved in the recognition of foreign molecules. In addition to the variability of the morphology of the cells that constitute different organs, many cell types also modify dynamically their morphology in response to environmental changes, leading to differential cell motility, migration, adhesion, polarity or intercellular contacts. This wide plasticity of cell morphology is promoted and maintained by the cytoskeleton, which is composed of the three interconnected actin micro filaments, tubulin microtubules and intermediate filaments networks, all capable of assembly and disassembly. Over the past few years, the Rho family of Ras-like GTPases emerged as key proteins that mediate extracellular signalling pathways leading to the forma- tion of polymerized actin-containing structures such as ruffles, lamellipodia and filopodia. Since the discovery of the first member RhoA in 1985, 13 mem- bers have so far been characterized in human cells. Most of Rho proteins are highly conserved between species as distant as yeast, slime mold, insects and mammals, which points to their fundamental role in cellular physiology.

Misanthropology: Science, Pseudoscience, and the Study of Humanity introduces students to key concepts in critical thinking across the four core branches of anthropology: cultural, linguistic, biological, and archaeological. It combines a critical analysis of anthropology as a field with current concepts in scientific skepticism. By deconstructing a range of global case studies in which anthropological research runs aground, the book teaches students to distinguish between legitimate science and pseudoscience. It covers key concepts in critical thinking and rigorous research, such as cognitive biases and logical fallacies, data collection and consensus, probabilistic thinking, as well as political, nationalist, racist biases. Students learn not only how to apply these concepts to anthropological research and fieldwork, but also to their consumption of everyday information. This book will appeal to anthropology students and will be particularly useful for instructors of introductory anthropology courses, as well as instructors of courses across the humanities and social sciences focused on inculcating critical thinking skills.

This volume is intended to complete the Cell Chemistry and physiology module. It is about how the traditional boundaries of cell chemistry and physiology are being erased by molecular biology. We do not think it necessary to elaborate on this theme, particularly since the body of core knowledge found in this volume brings us a stage closer to answering the question, "what makes cell biology into a new discipline?"
The first part of the volume deals with the chemistry of actin and myosin and is followed by chapters on cell motility, ATP synthesis in muscle, and contraction in smooth and skeletal muscle. Here the reader is immediately made aware of the contributions molecular biology is making to our understanding of the molecular mechanisms underlying muscle contraction. It is perhaps enough to point out that Huxley's concept of the cross-bridge cycle and generation of force can now be explained in molecular terms. Topics such as muscle fatigue and muscle disorders, as well as malignant hyperthermia are bound to arouse active learning in the student and set the stage for problem-based learning.
Most medical students look askance at thermobiology. We think this is a mistake; hence, we have included a section dealing with this subject. This brings us to the chapter on the heat shock response, which at the very outset makes clear that many stressors besides heat are known to result in heat shock gene expression. Many of the heat shock proteins occur in unstressed cells and some of them behave as chaperones. These proteins also reach high levels in a wide range of diseases including neurodegenerative disorders. Whether certain diseases are the result of mutations in the heat shock genes is not yet known. As will be appreciated, much of the work done in this field involved the use of cultured cells. Animal cells in culture are the subject of the last chapter.

Zsuzsa Berend presents a methodologically innovative ethnography of SurroMomsOnline.com, the largest surrogacy support website in the United States. Surrogates' views emerge from the stories, debates, and discussions that unfold online. The Online World of Surrogacy documents these collective meaning-making practices and explores their practical, emotional, and moral implications. In doing so, the book works through themes of interest across the social sciences, including definitions of parenthood, the symbolic role of money, reproductive loss, altruism, and the moral valuation of relationships.

For many years, de Waal has observed chimpanzees soothe distressed neighbors and bonobos share their food. Now he delivers fascinating fresh evidence for the seeds of ethical behavior in primate societies that further cements the case for the biological origins of human fairness. Interweaving vivid tales from the animal kingdom with thoughtful philosophical analysis, de Waal seeks a bottom-up explanation of morality that emphasizes our connection with animals. In doing so, de Waal explores for the first time the implications of his work for our understanding of modern religion. Whatever the role of religious moral imperatives, he sees it as a Johnny-come-lately role that emerged only as an addition to our natural instincts for cooperation and empathy.

But unlike the dogmatic neo-atheist of his book s title, de Waal does not scorn religion per se. Instead, he draws on the long tradition of humanism exemplified by the painter Hieronymus Bosch and asks reflective readers to consider these issues from a positive perspective: What role, if any, does religion play for a well-functioning society today? And where can believers and nonbelievers alike find the inspiration to lead a good life?

Rich with cultural references and anecdotes of primate behavior, The Bonobo and the Atheist engagingly builds a unique argument grounded in evolutionary biology and moral philosophy. Ever a pioneering thinker, de Waal delivers a heartening and inclusive new perspective on human nature and our struggle to find purpose in our lives."

This volume is concerned with the enzymes of the nervous system. Cerebral enzymes form the basis of the functional brain. They are needed for the control of the energetics of the nervous system, whether it be their release or their direction; for the elaboration of transmitters and for their destruction; for the synthesis, transport, and breakdown of all metabolites of the nervous system. They are indispensable for the control of the multitude of factors that govern our thinking and our behavior. They make it possible for us to comprehend what is taking place around us and perhaps to understand what may be in store for us. Enzymes are the stuff of life, and no living cell can be without them. They are the results of many millions of years of evolution, from the time when biological membranes first came into being and were folded to produce the first cells within which the earliest enzymes were wrought. Countless changes have taken place within them, so that, now, only those enzymes exist that play specific roles in the functions of the living cells of today. Those in the nervous system possess a mUltiple role: in the creation, maintenance, and ultimate breakdown of the component cells and in enabling consciousness, perception, memory, and thought to become possible. But though life may go on forever, the enzymes that make life possible will undergo the many changes involved in the evolutionary process.

A biology professor's illuminating tour of the physical imperfections--from faulty knees to junk DNA--that make us human. "A funny, fascinating catalog of our collective shortcomings that's tough to put down."--Discover We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often--two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake? As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is indeed nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them. A rollicking, deeply informative tour of humans' four-billion-year-and-counting evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.

"Fascinating and exhilarating-Sean B. Carroll at his very best."-Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the world Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world. Like every other species, we humans are here by accident. But it is shocking just how many things-any of which might never have occurred-had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death. This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.

Evolution, Order and Complexity reflects topical interest in the relationship between the social and natural worlds. It represents the cutting edge of current thinking which challenges the natural/social dichotomy thesis by showing how the application of ideas which derive from biology can be applied and offer insight into the social realm. This is done by introducing the general system theory to the methodological debate on the relation of human and natural sciences.

This volume illustrates the extent to which the traditional distinction between biochemical and physiological processes is being obliterated by molecular biology. It can hardly be doubted that the revolution in cell and molecular biology is leading to core knowledge that provides an outline of the integrative and reductionist approach. We view this as the beginning of a new era, that of the integration of learning.
As in the preceding volumes, the choice of topics has been deliberate not only because of the need to keep the volume within reasonable bounds but also because of the need to avoid information over-load. Several relevant topics are dealt with in other modules; for example, the role of G proteins in transmembrane signalling is covered in the Membranes and Cell Signalling module (i.e., Volume 7). Omissions are of course inevitable but they are minor. A case in point is the subject of phosphatases, the treatment of which does not take into account calcineurin. One of the key functions of this Ca2+ -activated protein phosphatase that is also regulated by calmodulin is to desphosphorylate voltage-dependent Ca2+ channels. The mere recognition of such omissions before or after consulting textbooks and journals should be a spur to a more complete discussion by the student of the subject in a small group teaching setting.

Environmental pollution is an emerging global public health problem of both developing and developed nations. Such pollution is a major risk factor for many illnesses, including nervous system disorders. This book combines the highlights the effects of environmental pollution on brain biology. It will be a thorough overview of the pathophysiological and oxidative stress mechanisms and how environmental pollution affects the brain biology. The author discusses environmental pollution and brain development, memory, autism, hearing and vision loss and brain cancer. Several chapters address controversial topics such as the effect of Electromagnetic Field Radiation (RF-EMFR).

We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived and why we should emulate them are often based on speculation, not scientific evidence.

Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized, meaning that we are not biologically the same as our caveman ancestors. Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. And women don t go into shoe-shopping frenzies because their prehistoric foremothers gathered resources for their clans. As Zuk compellingly argues, such beliefs incorrectly assume that we re stuck finished evolving and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults ability to drink milk to the texture of our ear wax to show that we ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were meant to fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs.

From debunking the caveman diet to unraveling gender stereotypes, Zuk delivers an engrossing analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future."

'A stunner ... If you haven't got this book in your house, I don't know why' Chris Evans 'A startling wake-up call . . . Writing with the vim of a Bill Bryson and the technical knowledge of a scientist, Steele gives us a chance to grasp what's at stake' Independent 'An exhilarating journey . . . Steele is a superb guide' Telegraph 'A fascinating read with almost every page bursting with extraordinary facts . . . Read it now' Mail on Sunday Ageless is a guide to the biggest issue we all face. Ageing - not cancer, not heart disease - is the world's leading cause of death and suffering. What would the world be like if we could cure it? Living disease-free until the age of 100 is achievable within our lifetimes. In prose that is lucid and full of fascinating facts, Ageless introduces us to the cutting-edge research that is paving the way for this revolution. Computational biologist Andrew Steele explains what occurs biologically as we age, as well as practical ways we can slow down the process. He reveals how understanding the scientific implications of ageing could lead to the greatest discovery in the history of civilisation - one that has the potential to improve billions of lives, save trillions of dollars, and transform the human condition.

Many complex traits define the primate condition, including behaviors as fundamental as locomotion and traits as scrutinized as the dentition, and their study reveals dramatic evolutionary change across the primates. Genetic modifications are at the basis of these changes, but transformation of genetic information into phenotypes occurs at the level of the cell, which is the focus of this book. Contributors summarize novel methodologies to analyze the collective behavior of cells in forming tissues and organs influencing physiological functions and anatomical features that enable behaviors. Our goal is to review current knowledge and encourage others to adopt evolutionary cell biology to aid in deciphering the genotype-phenotype map that underlies the diversification of primates, human variation, and human evolution. The contributors to this book utilize advances in genetic analysis and visualization of cells and tissues and merge evolutionary developmental biology with evolutionary cell biology to address questions central to understanding human and primate evolution. Key Features Explores mechanisms underlying trait development, distribution, variation, and evolution, especially with respect to pigmentation, dental formulae, the skeleton, energetics, and temperature-related morphological variation Documents the advantages for anthropologists to work at the level of cells, focusing on how genes provide instructions for cells to make structure and how environment affects the behavior of cells Illustrates the role cell biology plays in pelage growth and pigmentation, facial morphology, melanin production in pigmentation, dental development and tooth loss, and energy expenditure Describes novel methodologies and techniques to analyze environment- and temperature-related influences on phenotypes Demonstrates how significant changes in life history occur at the level of the cell Related Titles Bianchi, L.

Osteobiographies: The Discovery, Interpretation and Repatriation of Human Remains contextualizes repatriation, or the transfer of authority for human skeletal remains from the perspective of bioarchaelogists and evolutionary biologists. It approaches repatriation from a global perspective, touching upon the most well-known Native American Graves Protection and Repatriation Act (NAGPRA) legislation of the United States, while also covering Canada and African countries. The book focuses on the stories behind human skeletons, analyzing their biological factors to determine evolution patterns. Sections present an overview of anatomy, genomics, and stable isotopes from dietary and environmental factors, and how to identify these in skeletal remains. The book then goes on to discuss European-origin, North American, and African paleopathology, ancient DNA links, and cultural issues and implications around repatriation. It concludes with case studies to show how information from archaeologically derived skeletons is vital to understanding human evolution and provide respectful histories behind the remains.
