For each chapter a synopsis is provided, highlighting the main points in a concise manner. The book is intended for professors and researchers in vascular biology, angiogenesis research and developmental biology. It furthermore offers an excellent basis for entry level researchers and newcomers to this field, as well as for teachers, graduate students, advanced science and medical students.
All being done, we went to Mrs Shipmans, who is a great butter-woman; and I did see there the most of milke and cream, and the cleanest, that I ever saw in my life (29 May 1661). Among others, Sir Wm. Petty did tell me that in good earnest, he hath in his will left such parts of his estate to him that could invent such and such things -as among others, that could discover truly the way of milk coming into the breasts of a woman ... (22 March 1665). My wife tells me that she hears that my poor aunt James hath had her breast cut off here in tow- her breast having long been out of order (5 May 1665). From the Diary of Samuel Pepys, published as The Shorter Pepys (edited by R. Latham), Penguin Books (1987) The long-standing ultimate importance of research on the mammary gland is illustrated by the importance attached to cows' milk for human consumption, to human lactation and to breast cancer by Samuel Pepys and his contemporaries in the middle of the 17th century. Research has tended to develop in isolation in these three areas of continuing contemporary importance largely because in most countries, the underlying science of agricultural productivity is funded separately from the underlying science of human health and welfare.
The vertebrate retina has a form that is closely and clearly linked to its func tion. Though its fundamental cellular architecture is conserved across verte brates, the retinas of individual species show variations that are also of clear and direct functional utility. Its accessibility, readily identifiable neuronal types, and specialized neuronal connectivity and morphology have made it a model system for researchers interested in the general questions of the genet ic, molecular, and developmental control of cell type and shape. Thus, the questions asked of the retina span virtually every domain of neuroscientific inquiry-molecular, genetic, developmental, behavioral, and evolutionary. Nowhere have the interactions of these levels of analysis been more apparent and borne more fruit than in the last several years of study of the develop ment of the vertebrate retina. Fields of investigation have a natural evolution, rdoving through periods of initial excitement, of framing of questions and controversy, to periods of synthesis and restatement of questions. The study of the development of the vertebrate retina appeared to us to have reached such a point of synthesis. Descriptive questions of how neurons are generated and deployed, and ques tions of mechanism about the factors that control the retinal neuron's type and distribution and the conformation of its processes have been posed, and in good part answered. Moreover, the integration of cellular accounts of development with genetic, molecular, and whole-eye and behavioral accounts has begun."
Would you ask a honeybee to point at a screen and recognise a facial expression? Or ask an elephant to climb a tree? While humans and non-human species may inhabit the same world, it's likely that our perceptual worlds differ significantly. Emphasising Uexkull's concept of 'umwelt', this volume offers practical advice on how animal cognition can be successfully tested while avoiding anthropomorphic conclusions. The chapters describe the capabilities of a range of animals - from ants, to lizards to chimpanzees - revealing how to successfully investigate animal cognition across a variety of taxa. The book features contributions from leading cognition researchers, each offering a series of examples and practical tips drawn from their own experience. Together, the authors synthesise information on current field and laboratory methods, providing researchers and graduate students with methodological advice on how to formulate research questions, design experiments and adapt studies to different taxa.
This book provides an interdisciplinary review of one of the great unsolved mysteries that has fascinated scientists for over 150 years: the origin of chirality in biomolecules. Current advances in fields as diverse as space exploration, prebiotic chemistry and high-energy physics may help to provide an answer. Important pieces of information will come from observations at the two frontiers of science: outer space and the subatomic world. Observation of distant planets, galaxies, and even actual sampling of celestial objects from beyond the solar system are projects currently underway. At the other end of the spectrum, there are experiments that study the elemental properties of matter, such as symmetry, and interactions with the fundamental forces. Completely revised and updated this new edition once again unifies all the theories of the origin of biomolecular homochirality together in a single source. This complete, interdisciplinary review of an intriguing subject condenses a large and disparate range of contributions from journals in almost every scientific field. The various theories have been organized, interrelated and explained in a unified way. It is fundamental, comprehensive and structured to be accessible for educational purposes.
Franklin M. Harold's On Life reveals what science can tell us about the living world. All creatures, from bacteria and redwoods to garden snails and humans, belong to a single biochemical family. We all operate by the same principles and are all made up of cells, either one or many. We flaunt capacities that far exceed those of inanimate matter, yet we stand squarely within the material world. So what is life, anyway? How do living things function, and how did they come into existence? Questions like these have baffled philosophers and scientists since antiquity, but over the past half-century answers have begun to emerge. Offering an inside look, Franklin M. Harold makes life accessible to readers interested in the biological big picture. The book traces how living things operate, focusing on the interplay of biology with physics and chemistry. He asserts that biology stands apart from the physical sciences because life revolves around organization- that is, purposeful order. On Life aims to make life intelligible by giving readers an understanding of the biological landscape; it sketches the principles as biologists presently understand them and highlights major unresolved issues. What emerges is a biology bracketed by two stubborn mysteries: the nature of the mind and the origin of life. This portrait of biology is comprehensible but inescapably complex, internally consistent, and buttressed by a wealth of factual knowledge.
Intended for undergraduate and graduate courses in plant
development, this book explains how the cells of a plant acquire
and maintain their specific fates. Plant development is a
continuous process occurring throughout the life cycle, with
similar regulatory mechanisms acting at different stages and in
different parts of the plant. Rather than focussing on the life
cycle, the book is structured around these underlying mechanisms,
using case studies to provide students with a framework to
understand the many factors, both environmental and endogenous,
that combine to regulate development and generate the enormous
diversity of plant forms.
One hundred years after Darwin considered how sexual selection shapes the behavioral and morphological characteristics of males for acquiring mates, Parker realized that sexual selection continues after mating through sperm competition. Because females often mate with multiple males before producing offspring, selection favors adaptations that allow males to preempt sperm from previous males and to prevent their own sperm from preemption by future males. Since the 1970s, this area of research has seen exponential growth, and biologists now recognize sperm competition as an evolutionary force that drives such adaptations as mate guarding, genital morphology, and ejaculate chemistry across all animal taxa. The insects have been critical to this research, and they still offer the greatest potential to reveal fully the evolutionary consequences of sperm competition. This book analyzes and extends thirty years of theoretical and empirical work on insect sperm competition. It considers both male and female interests in sperm utilization and the sexual conflict that can arise when these differ. It covers the mechanics of sperm transfer and utilization, morphology, physiology, and behavior. Sperm competition is shown to have dramatic effects on adaptation in the context of reproduction as well as far-reaching ramifications on life-history evolution and speciation. Written by a top researcher in the field, this comprehensive, up-to-date review of the evolutionary causes and consequences of sperm competition in the insects will prove an invaluable reference for students and established researchers in behavioral ecology and evolutionary biology.
'Mind-blowing ... It is a hugely important book ... His story is crucial' Matt Ridley, The Times One of the world's top behavioural geneticists argues that we need a radical rethink about what makes us who we are The blueprint for our individuality lies in the 1% of DNA that differs between people. Our intellectual capacity, our introversion or extraversion, our vulnerability to mental illness, even whether we are a morning person - all of these aspects of our personality are profoundly shaped by our inherited DNA differences. In Blueprint, Robert Plomin, a pioneer in the field of behavioural genetics, draws on a lifetime's worth of research to make the case that DNA is the most important factor shaping who we are. Our families, schools and the environment around us are important, but they are not as influential as our genes. This is why, he argues, teachers and parents should accept children for who they are, rather than trying to mould them in certain directions. Even the environments we choose and the signal events that impact our lives, from divorce to addiction, are influenced by our genetic predispositions. Now, thanks to the DNA revolution, it is becoming possible to predict who we will become, at birth, from our DNA alone. As Plomin shows us, these developments have sweeping implications for how we think about parenting, education, and social mobility. A game-changing book by a leader in the field, Blueprint shows how the DNA present in the single cell with which we all begin our lives can impact our behaviour as adults.
The scope of the book is to highlight the diverse roles of cilia in human development and disease. Almost all cell types form cilia and although they were first detected about 200 years ago, their significance was unclear. In the past ten years, it has become obvious that cilia have got sensory functions, as well as roles in motility and their mis-formation or the deregulation of the signaling pathways they control has been associated with defective development and human disease. Although research has concentrated on the role of the cilium in each organ, no effort has been made so far to bring all this information together and relate it to the various human diseases. This book aims to gather all the expertise that has been acquired on primary cilia and translate it into a medical and research context that will be of interest to postgraduate students, researchers, medics and scientists.
Over the past decade, advances in both molecular developmental biology and evolutionary ecology have made possible a new understanding of organisms as dynamic systems interacting with their environments. This innovative book synthesizes a wealth of recent research findings to examine how environments influence phenotypic expression in individual organisms (ecological development or 'eco-devo'), and how organisms in turn alter their environments (niche construction). A key argument explored throughout the book is that ecological interactions as well as natural selection are shaped by these dual organism-environment effects. This synthesis is particularly timely as biologists seek a unified contemporary framework in which to investigate the developmental outcomes, ecological success, and evolutionary prospects of organisms in rapidly changing environments. Organism and Environment is an advanced text suitable for graduate level students taking seminar courses in ecology, evolution, and developmental biology, as well as academics and researchers in these fields.
A revelatory tale of how the human brain develops, from conception to birth and beyond By the time a baby is born, its brain is equipped with billions of intricately crafted neurons wired together through trillions of interconnections to form a compact and breathtakingly efficient supercomputer. Zero to Birth takes you on an extraordinary journey to the very edge of creation, from the moment of an egg's fertilization through each step of a human brain's development in the womb-and even a little beyond. As pioneering experimental neurobiologist W. A. Harris guides you through the process of how the brain is built, he takes up the biggest questions that scientists have asked about the developing brain, describing many of the thrilling discoveries that were foundational to our current understanding. He weaves in a remarkable evolutionary story that begins billions of years ago in the Proterozoic eon, when multicellular animals first emerged from single-cell organisms, and reveals how the growth of a fetal brain over nine months reflects the brain's evolution through the ages. Our brains have much in common with those of other animals, and Harris offers an illuminating look at how comparative animal studies have been crucial to understanding what makes a human brain human. An unforgettable chronicle of one of nature's greatest achievements, Zero to Birth describes how the brain's incredible feat of orchestrated growth ensures that every brain is unique, and how breakthroughs at the frontiers of science are helping us to decode many traits that only reveal themselves later in life.
Animal life, now and over the past half billion years, is
incredibly diverse. Describing and understanding the evolution of
this diversity of body plans - from vertebrates such as humans and
fish to the numerous invertebrate groups including sponges,
insects, molluscs, and the many groups of worms - is a major goal
of evolutionary biology. In this book, a group of leading
researchers adopt a modern, integrated approach to describe how
current molecular genetic techniques and disciplines as diverse as
palaeontology, embryology, and genomics have been combined,
resulting in a dramatic renaissance in the study of animal
evolution.
Leading gender and science scholar Sarah S. Richardson charts the untold history of the idea that a woman's health and behavior during pregnancy can have long-term effects on her descendants' health and welfare. The idea that a woman may leave a biological trace on her gestating offspring has long been a commonplace folk intuition and a matter of scientific intrigue, but the form of that idea has changed dramatically over time. Beginning with the advent of modern genetics at the turn of the twentieth century, biomedical scientists dismissed any notion that a mother-except in cases of extreme deprivation or injury-could alter her offspring's traits. Consensus asserted that a child's fate was set by a combination of its genes and post-birth upbringing. Over the last fifty years, however, this consensus was dismantled, and today, research on the intrauterine environment and its effects on the fetus is emerging as a robust program of study in medicine, public health, psychology, evolutionary biology, and genomics. Collectively, these sciences argue that a woman's experiences, behaviors, and physiology can have life-altering effects on offspring development. Tracing a genealogy of ideas about heredity and maternal-fetal effects, this book offers a critical analysis of conceptual and ethical issues-in particular, the staggering implications for maternal well-being and reproductive autonomy-provoked by the striking rise of epigenetics and fetal origins science in postgenomic biology today.
A provocative and timely case for how the science of genetics can help create a more just and equal society In recent years, scientists like Kathryn Paige Harden have shown that DNA makes us different, in our personalities and in our health-and in ways that matter for educational and economic success in our current society. In The Genetic Lottery, Harden introduces readers to the latest genetic science, dismantling dangerous ideas about racial superiority and challenging us to grapple with what equality really means in a world where people are born different. Weaving together personal stories with scientific evidence, Harden shows why our refusal to recognize the power of DNA perpetuates the myth of meritocracy, and argues that we must acknowledge the role of genetic luck if we are ever to create a fair society. Reclaiming genetic science from the legacy of eugenics, this groundbreaking book offers a bold new vision of society where everyone thrives, regardless of how one fares in the genetic lottery.
Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: how can something as large and complex as a human body organize itself from the simplicity of a fertilized egg? A convergence of ideas from embryology, genetics, physics, networks, and control theory has begun to provide real answers. Based on the central principle of 'adaptive self-organization', it explains how the interactions of many cells, and of the tiny molecular machines that run them, can organize tissue structures vastly larger than themselves, correcting errors as they go along and creating new layers of complexity where there were none before. Life Unfolding tells the story of human development from egg to adult, from this perspective, showing how our whole understanding of how we come to be has been transformed in recent years. Highlighting how embryological knowledge is being used to understand why bodies age and fail, Jamie A. Davies explores the profound and fascinating impacts of our newfound knowledge.
This lab manual is designed to give students experience with a wide variety of model systems currently in use by developmental biologists. Experiments range from classic slide or whole animal observations to more modern immunohistochemistry and manipulation of gene expression. All of these experiments can be completed on a relatively small budget.
Female and male brains are different, thanks to hormones coursing through the brain before birth. That s taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren t more women physicists or more stay-at-home dads. In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of human brain organization theory, Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn t scientific at all. Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development.

There is a major demand for people with scientific training in a wide range of professions based on and maintaining relations with science. However, there is a lack of good first-hand information about alternative career paths to research. From entrepreneurship, industry and the media to government, public relations, activism and teaching, this is a readable guide to science based skills, lifestyles and career paths. The ever-narrowing pyramid of opportunities within an academic career structure, or the prospect of a life in the laboratory losing its attraction, mean that many who trained in science and engineering now look for alternative careers. Thirty role models who began by studying many different disciplines give personal guidance for graduates, postgraduates and early-career scientists in the life sciences, physical sciences and engineering. This book is an entertaining resource for ideas about, and directions into, the many fields which they may not be aware of or may not have considered.
