Book excerpt: Most hair follicles on the human body have evolved to be miniaturized, rendering us practically 'naked'. Despite sparse body hair, we retain thick hair on our scalps that varies significantly among populations. Yet little is known of the evolutionary history of our scalp hair and its variation. It has been suggested that scalp hair, and tightly curled hair in particular, evolved to moderate thermal load in humans. However, this functional hypothesis has never been directly tested. Existing research on human hair variation has relied on subjective and qualitative descriptors of hair morphology and samples have been historically had a strong Eurocentric bias. Despite its relevance to several evolutionary hypotheses, scalp hair has yet to be studied in a comprehensive evolutionary, functional, and genetic framework. The functional work described in this dissertation revisits the recurrent question of the role of thermoregulation in shaping early human evolution. This work is the first to extensively investigate the potential role of scalp hair and variation in its morphology in modulating heat balance in humans. More broadly, the methods, samples, and hypotheses tested in this dissertation serve to replace racialized terminology and conceptions of human scalp hair variation. Current public discussions of human biological variation demonstrate that anthropologists must continue to oppose tendencies to perceive human variation in racial terms, and focusing on hair--one of the most visible and variable human traits--will provide anthropologists with evidence of how and why variation evolved. This dissertation synthesizes methods and knowledge from various disciplines with new data, generating an innovative perspective on both human origins and modern variation and laying the foundation for future work.

Book excerpt: "Our intimate connection with the world, skin protects us while advertising our health, our identity, and our individuality. This synthetic overview, written with a poetic touch and taking many intriguing side excursions, is a guidebook to the pliable covering that makes us who we are. This book celebrates the evolution of three unique attributes of human skin: its naked sweatiness, its distinctive sepia rainbow of colors, and its remarkable range of decorations. Author Jablonski begins with a look at skin's structure and functions and then tours its three-hundred-million-year evolution, delving into such topics as the importance of touch and how the skin reflects and affects emotions. She examines the modern human obsession with age-related changes in skin, especially wrinkles, then turns to skin as a canvas for self-expression, exploring our use of cosmetics, body paint, tattooing, and scarification"--Publisher's description.

Book excerpt: There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.

Recent research has shown that melanins are produced not only in the skin but also in many other sites such as the eye, inner ear, muscles, etc., - where they are engaged in some unanticipated roles. The details of the synthetic pathway, the complexities of its regulation and biological significance that have been unravelled in recent research comprise a fascinating story and are of key importance in understanding the nature of diseases, including malignant melanoma one of the most rapidly spreading cancers.

Available in PDF, EPUB and Kindle. Book excerpt: In 2000, with the success of the Human Genome Project, scientists declared the death of race in biology and medicine. But within five years, many of these same scientists had reversed course and embarked upon a new hunt for the biological meaning of race. Drawing on personal interviews and life stories, Race Decoded takes us into the world of elite genome scientists—including Francis Collins, director of the NIH; Craig Venter, the first person to create a synthetic genome; and Spencer Wells, National Geographic Society explorer-in-residence, among others—to show how and why they are formulating new ways of thinking about race. In this original exploration, Catherine Bliss reveals a paradigm shift, both at the level of science and society, from colorblindness to racial consciousness. Scientists have been fighting older understandings of race in biology while simultaneously promoting a new grand-scale program of minority inclusion. In selecting research topics or considering research design, scientists routinely draw upon personal experience of race to push the public to think about race as a biosocial entity, and even those of the most privileged racial and social backgrounds incorporate identity politics in the scientific process. Though individual scientists may view their positions differently—whether as a black civil rights activist or a white bench scientist—all stakeholders in the scientific debates are drawing on memories of racial discrimination to fashion a science-based activism to fight for social justice.

Book excerpt: Over the past century, we have made great strides in reducing rates of disease and enhancing people's general health. Public health measures such as sanitation, improved hygiene, and vaccines; reduced hazards in the workplace; new drugs and clinical procedures; and, more recently, a growing understanding of the human genome have each played a role in extending the duration and raising the quality of human life. But research conducted over the past few decades shows us that this progress, much of which was based on investigating one causative factor at a time—often, through a single discipline or by a narrow range of practitioners—can only go so far. Genes, Behavior, and the Social Environment examines a number of well-described gene-environment interactions, reviews the state of the science in researching such interactions, and recommends priorities not only for research itself but also for its workforce, resource, and infrastructural needs.

Book excerpt: The iris is a circular, pigmented tissue that separates the anterior chamber of the eye from the posterior chamber. It has a crucial role on controlling the amount of the light entering the eye through its central opening “the pupil". The Iris has multiple important functions that support and provide image clarity on the retina. However, it is a largely neglected part of the eye, compared to the cornea lens, retina, and optic nerve, and has not been focused on in a comprehensive way until now. The Iris: Understanding the Essentials, combines different aspects of scientific information from a variety of fields, such as anatomy, histopathology, molecular biology, electron microscopy and other diagnostic modalities. Each chapter will include pearls and summary points, and this multi-disciplinary approach helps the clinician diagnose and treat the large variety of diseases that affect the iris, with the main emphasize on pigmentary pathological changes that can affect the color of the eye. Written as a reference review book for universities, practicing ophthalmologists, Ophthalmology residents, pharmaceutical companies and diagnostic equipment manufacturing companies this book summarizes the information in an easy-to-use manner to help the reader better understand the iris, iris structure, physiology and function.

Available in PDF, EPUB and Kindle. Book excerpt: Hair is a sophisticated bio-based material, whether it is on a human head or part of a mammalian coat. In particular, the role of the proteins in the follicle, integral to hair development, are not well understood. This new book seeks to integrate the latest research in proteomic and morphological studies into a coherent description of fibre development from the follicle to its final mature, keratinized form. To achieve this the book has been divided into three sections. The first describes the keratins, their associated proteins and how they assemble into intermediate filaments in the fibre. The second covers the latest information on the morphological changes that occur from the base of the follicle, through the keratinization process to the mature fibre and the role that proteins play in this. The final section delves into fundamental fibre properties such as crosslinking, thermal and oxidative modifications and how these affect the mature fibre. The editors of this book are internationally recognised for their work in the area of mammalian hair, Jeffrey Plowman for his knowledge of the proteomics of the fibre, Santanu Deb-Choudhury for his work in the area of crosslinking in the fibre and Duane Harland for his understanding of the morphological development of the fibre. Together they have collected material from other international experts: Leopold Eckhart and Florian Ehrlich for their knowledge of the evolution of keratins; Dong Dong Wu and David Irwin for their studies on keratin associated protein evolution; David Parry and Bruce Fraser for their work on keratin and keratin associated protein structure and assembly; John McKinnon for his studies on macrofibril formation; Crisan Popescu for the thermodynamics of keratins; and Jolon Dyer for his oxidative modification studies of keratins. This book provides a comprehensive introduction, and useful reference guide to hair biology and will be of interest to both scientists and technologists.

Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Hair Growth is based on a conference on The Biology of Hair Growth, sponsored by the British Society for Research on Ageing, held at the Royal College of Surgeons, in London, 7-9 August 1957. The papers presented at this conference, and a few others, have been gathered in this book to serve as a source reference for all those interested in research on hair and hair growth. The application of modern methods in histology, cytology, histochemistry, physiology, electron microscopy, the use of radioactive isotopes, and modern biochemical techniques have given greater insight into the phenomena of growth and differentiation of hair follicles than ever before. The book opens with a chapter on the embryology of hair. Separate chapters follow on the anatomy and histochemistry of the hair follicle; the electron microscopy of keratinized tissues; the chemistry of keratinization; the mitotic activity of the follicle; and the the vascularity and patterns of growth of hair follicles. Subsequent chapters deal with behavior of pigment cells and epithelial cells in the hair follicle; the nature of hair pigment; the effects of nutrition on hair growth; and effects of chemical agents, ionizing radiation, and particular illnesses on hair roots.

Available in PDF, EPUB and Kindle. Book excerpt: "What makes you the way you are--and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains. Deftly guiding us through important new research, including his own groundbreaking work, he explains how variations in the way our brains develop before birth strongly influence our psychology and behavior throughout our lives, shaping our personality, intelligence, sexuality, and even the way we perceive the world. We all share a genetic program for making a human brain, and the program for making a brain like yours is specifically encoded in your DNA. But, as Mitchell explains, the way that program plays out is affected by random processes of development that manifest uniquely in each person, even identical twins. The key insight of Innate is that the combination of these developmental and genetic variations creates innate differences in how our brains are wired--differences that impact all aspects of our psychology--and this insight promises to transform the way we see the interplay of nature and nurture. Innate also explores the genetic and neural underpinnings of disorders such as autism, schizophrenia, and epilepsy, and how our understanding of these conditions is being revolutionized. In addition, the book examines the social and ethical implications of these ideas and of new technologies that may soon offer the means to predict or manipulate human traits. Compelling and original, Innate will change the way you think about why and how we are who we are."--Provided by the publisher.

Available in PDF, EPUB and Kindle. Book excerpt: Although a very fragile structure, the skin barrier is probably one of the most important organs of the body. Inward/out it is responsible for body integrity and outward/in for keeping microbes, chemicals, and allergens from penetrating the skin. Since the role of barrier integrity in atopic dermatitis and the relationship to filaggrin mutations was discovered a decade ago, research focus has been on the skin barrier, and numerous new publications have become available. This book is an interdisciplinary update offering a wide range of information on the subject. It covers new basic research on skin markers, including results on filaggrin and on methods for the assessment of the barrier function. Biological variation and aspects of skin barrier function restoration are discussed as well. Further sections are dedicated to clinical implications of skin barrier integrity, factors influencing the penetration of the skin, influence of wet work, and guidance for prevention and saving the barrier. Distinguished researchers have contributed to this book, providing a comprehensive and thorough overview of the skin barrier function. Researchers in the field, dermatologists, occupational physicians, and related industry will find this publication an essential source of information.

Book excerpt: "A work of enormous breadth, likely to pleasantly surprise both general readers and experts."—New York Times Book Review This revolutionary book provides fresh answers to long-standing questions of human origins and consciousness. Drawing on his breakthrough research in comparative neuroscience, Terrence Deacon offers a wealth of insights into the significance of symbolic thinking: from the co-evolutionary exchange between language and brains over two million years of hominid evolution to the ethical repercussions that followed man's newfound access to other people's thoughts and emotions. Informing these insights is a new understanding of how Darwinian processes underlie the brain's development and function as well as its evolution. In contrast to much contemporary neuroscience that treats the brain as no more or less than a computer, Deacon provides a new clarity of vision into the mechanism of mind. It injects a renewed sense of adventure into the experience of being human.
