Advances in genetics research, largely, though not entirely, spawned by the Human Genome Project, have led to a broad array of new technologies that promise to revolutionize life as we have known it. Medicine and agriculture are already starting to utilize new technologies to greatly improve disease prevention and treatment and food production. Yet, these "improvements" often raise ethical questions that are not easy to untangle. Some have gone as far to as to argue that certain applications, such as embryonic stem cell research, threaten the very fiber of our moral compass. While the application of scientific advances to better mankind has always raised thorny ethical issues, the ethical impact of genetic advances arguably reaches a new height because the applicability of advances is exceptionally broad, deep, and potentially irreversible. To utilize such technologies could mean saving thousands of lives, but where and how do we draw the line? Here, Barash sheds light on the actual ethical concerns surrounding various types of genetic technologies, introducing readers to the competing issues at stake in the arguments about the scientific application of the new technologies available and those on the horizon. She begins by illustrating the history of genetic advances, their societal applications, and the ethical issues that have arisen from those applications. Using case studies and examples throughout, she walks readers through the various considerations involved in a variety of areas related to the application of genetic technologies currently available and possible in the future. Covering topics ranging from stem cell research to genetically modified food, genetic mapping to cloning, this book offers a thoughtful approach to the complex issues at play in the various fields of genetic technologies.
Although numerous studies have been made of the Western educated political elite of colonial Nigeria in particular, and of Africa in general, very few have approached the study from a perspective that analyzes the impacts of indigenous institutions on the lives, values, and ideas of these individuals. This book is about the diachronic impact of indigenous and Western agencies in the upbringing, socialization, and careers of the colonial Igbo political elite of southeastern Nigeria. The thesis argues that the new elite manifests the continuity of traditions and culture and therefore their leadership values and the impact they brought on African society cannot be fully understood without looking closely at their lived experiences in those indigenous institutions where African life coheres. The key has been to explore this question at the level of biography, set in the context of a carefully reconstructed social history of the particular local communities surrounding the elite figures. It starts from an understanding of their family and village life, and moves forward striving to balance the familiar account of these individuals in public life, with an account of the ongoing influences from family, kinship, age grades, marriage and gender roles, secret societies, the church, local leaders and others. The result is not only a model of a new approach to African elite history, but also an argument about how to understand these emergent leaders and their peers as individuals who shared with their fellow Africans a dynamic and complex set of values that evolved over the six decades of colonialism.

The study of the prehistory of East Asia is developing very rapidly. In uncovering the story of the flows of human migration that constituted the peopling of East Asia there exists widespread debate about the nature of evidence and the tools for correlating results from different disciplines. Drawing upon the latest evidence in genetics, linguistics and archaeology, this exciting new book examines the history of the peopling of East Asia, and investigates the ways in which we can detect migration, and its different markers in these fields of inquiry. Results from different academic disciplines are compared and reinterpreted in the light of evidence from others to attempt to try and generate consensus on methodology. Taking a broad geographical focus, the book also draws attention to the roles of minority peoples - hitherto underplayed in accounts of the region's prehistory - such as the Austronesian, Tai-Kadai and Altaic speakers, whose contribution to the regional culture is now becoming accepted. Past Human Migrations in East Asia presents a full picture of the latest research on the peopling of East Asia, and will be of interest to scholars of all disciplines working on the reconstruction of the peopling of East and North East Asia.
Biologist James Watson and physicist Francis Crick's 1953 revelation about the double helix structure of DNA is the foundation of virtually every advance in our modern understanding of genetics and molecular biology. But how did Watson and Crick do it-and why were they the ones who succeeded? In truth, the discovery of DNA's structure is the story of a race among five scientists for advancement, fame and immortality: Watson, Crick, Rosalind Franklin, Maurice Wilkins and Linus Pauling. They were fascinating and brilliant, with strong personalities that often clashed. But it is Rosalind Franklin who becomes a focal point for Howard Markel. The Secret of Life is a story of genius and perseverance but also a saga of cronyism, misogyny, anti-Semitism and misconduct. Markel brilliantly recounts the intense intellectual journey-and the fraught personal relationships-that resulted in the discovery of DNA.
This is the story of a profound revolution in the way biologists
explore life's history, understand its evolutionary processes, and
reveal its diversity. It is about life's smallest entities, deepest
diversity, and greatest cellular biomass: the microbiosphere. Jan
Sapp introduces us to a new field of evolutionary biology and a new
brand of molecular evolutionists who descend to the foundations of
evolution on Earth to explore the origins of the genetic system and
the primary life forms from which all others have emerged. In so
doing, he examines-from Lamarck to the present-the means of
pursuing the evolution of complexity, and of depicting the greatest
differences among organisms.
This book discusses 14 model organisms and are used by thousands of researchers, teachers, and students each year in laboratories and classrooms, around the globe. Though acknowledged in innumerable scientific journal articles, little is generally known about the origin of these collections, how the organisms contained within them have been acquired, and how they are maintained and distributed. While some collections such as Drosophila have long histories others, such as the collection of Brachionus, are relatively new. They vary greatly in size. Yet, all have contributed and are continuing to contribute to global research efforts in many areas of scientific research as diverse as tissue regeneration, skin cancer, evolution, water purity, gene function, and hundreds of others. In addition to providing the raw materials for national and international research programs, these collections also provide educational tools used by colleges and high schools. The chapters in this book attempt to provide a brief look at the individual organisms, how they came to be accepted as model organisms, the history of the individual collections, examples of how the organisms have been and are being used in scientific research, and a description of the facilities and procedures used to maintain them. Features: * Provides an in-depth look at the collections of 14 model organisms that have enabled innumerable scientific breakthroughs over decades, and that continue to do so. * Includes detailed descriptions of the operating procedures used for the maintenance of each model organism collection. * Discusses the holdings of the collections of model organisms and its relevance to past, current and future scientific research. * Written by the leaders in the field of the management of model organisms.
A large variety of organisms - from bacteria to man - form minerals. Skeletons, teeth, spicules, spines, shells, darts, and granules are all mineral-containing tissues. Why, where, and how these minerals form are the central questions addressed in this book. These questions have become important in many fields. Preserved fossils are used to interpret ancient climates, changes in chemical composition of the oceans, or to date geological and archaeological deposits and artefacts. Materials scientists investigate mineralized tissues to try to determine the design principles used by organisms to form strong materials, and many medical problems are associated with normal and pathological mineralization. Heinz Lowenstam, the pioneering researcher in biomineralization, and his former student Stephen Weiner discuss the basic principles of mineral formation by organisms, and compare the various mineralization processes. Reference tables list all known cases in which organisms form minerals.

Plant improvement has shifted its focus from yield, quality and disease resistance to factors that will enhance commercial export, such as early maturity, shelf life and better processing quality. Conventional plant breeding methods aiming at the improvement of a self-pollinating crop usually take 10-12 years to develop and release of the new variety. During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop varieties. This book focuses on the accelerated breeding technologies that have been adopted for major oil crops. It summarizes concepts dealing with germplasm enhancement and development of improved varieties based on innovative methodologies that include doubled haploidy, marker assisted selection, marker assisted background selection, genetic mapping, genomic selection, high-throughput genotyping, high-throughput phenotyping, mutation breeding, reverse breeding, transgenic breeding, shuttle breeding, speed breeding, low cost high-throughput field phenotyping, etc. This edited volume is therefore an excellent reference on accelerated development of improved crop varieties.

Chaetomium genus was established by Gustav Kunze in 1817. According to Index Fungorum Partnership, there are 273 Chaetomium species accepted till now. Members of the genus Chaetomium are capable of colonizing various substrates and are well-known for their ability to degrade cellulose and to produce a variety of bioactive metabolites. More than 200 compounds have been reported from this genus. A huge number of new and bioactive secondary metabolites associated with unique and diverse structural types, such as chaetoglobosins, epipolythiodioxopiperazines, azaphilones, depsidones, xanthones, anthraquinones, chromones, and steroids, have been isolated and identified. Many of the compounds have been reported to possess significant biological activities, such as antitumor, antimalarial, cytotoxic, enzyme inhibitory, antimicrobial, phytotoxic, antirheumatoid and other activities. Chaetomium taxa are frequently reported to be cellulase and ligninase producers with the ability to degrade cellulosic and woody materials. This is the first, comprehensive volume covering Chaetomium genus in detail. It includes the latest research, methods, and applications, and was written by scholars working directly in the field. The book also contains informative illustrations and is fully referenced for further reading.
With the rise of genomics, the life sciences have entered a new era. Maps of genomes have become the icons for a comprehensive knowledge of the organism on a previously unattained level of complexity, and the organisation of genetic knowledge in maps has been a major driving force in the establishment of the discipline. This book provides a comprehensive history of molecular genetics and genomics. The first section of the book shows how the genetic cartography of classical genetics was linked to the molecular analysis of gene structure through the introduction of new model organisms such as bacteria and through the invention of new experimental tools such as gene transfer. The second section addresses the moral and political economy of human genome sequencing in all its technical, epistemic, social and economic complexity. With detailed analyses of the scientific practices of mapping and its illustration of the diversity of mapping practices this book is a significant contribution to the history of genetics. A companion volume from the same editors - Classical Genetic Research and Its Legacy: The Mapping Cultures of Twentieth Century Genetics - covers the history of mapping procedures as they were developed in classical genetics.

Moreover, this book describes the development and advancement of fungal genes and the ways in which these are being exploited in species of economic importance either in biotechnology or in biochemistry.
"Advances in molecular genetics have led to the increasing availability of genetic testing for a variety of inherited disorders. While this new knowledge presents many obvious health benefits to prospective individuals and their families it also raises complex ethical and moral dilemmas for families as well as genetic professionals. This book explores the ways in which genetic testing generates not only probabilities of potential futures, but also enjoys new forms of social, individual and professional responsibility. Concerns about confidentiality and informed consent involving children, the assessment of competence and maturity, the ability to engage in shared decision-making through acts of disclosure and choice, are just some of the issues that are examined in detail"--Provided by publisher.

Woody plants belong to various taxonomic groups, which are heterogeneous in morphology, physiology, and geographic distribution. OtheJWise, they have neither strong evolutionruy relationships nor share a conunon habitat. They are a primaIy source of fiber and timber, and also include many edible fruit species. Their unique phenotypic behavior includes a perennial habit associated with extensive secondary growth. Additional characteristics of woody plants include: developmental juvenility and maturity with respect to growth habit, flowering time, and morphogenetic response in tissue cultures; environmental control of bud dormancy and flowering cycles; variable tolerance to abiotic stresses, wounding and pathogens; and long distance transport of water and IRltrients. Woody plants, particularly tree species, have been the focus of numerous physiological studies to understand their specialized functions, however, only recently they have become the target of molecular studies. Recent advances in our understanding of signal transduction pathways for environmental responses in herbaceous plants, including the identification and cloning of genes for proteins involved in signal transduction. should provide useful leads to undertake parallel studies with woody plants. Molecular mapping techniques, coupled with the availability of cloned genes from herbaceous plants, should provide shortcuts to cloning relevant genes from woody plants. The unique phenotypes of these plants can then be targeted for improvement through genetic engineering.
Taking us to the cutting edge of the new frontier of medicine, a visionary biotechnologist and a pathbreaking researcher show how we can optimize our health in ways that were previously unimaginable. We are on the cusp of a major transformation in healthcare—yet few people know it. At top hospitals and a few innovative health-tech startups, scientists are working closely with patients to dramatically extend their “healthspan”—the number of healthy years before disease sets in. In The Age of Scientific Wellness, two visionary leaders of this revolution in health take us on a thrilling journey to this new frontier of medicine. Today, most doctors wait for clinical symptoms to appear before they act, and the ten most commonly prescribed medications confer little or no benefit to most people taking them. Leroy Hood and Nathan Price argue that we must move beyond this reactive, hit-or-miss approach to usher in real precision health—a form of highly personalized care they call “scientific wellness.” Using information gleaned from our blood and genes and tapping into the data revolution made possible by AI, doctors can catch the onset of disease years before symptoms arise, revolutionizing prevention. Current applications have shown startling results: diabetes reversed, cancers eliminated, Alzheimer’s avoided, autoimmune conditions kept at bay. This is not a future fantasy: it is already happening, but only for a few patients and at high cost. It’s time to make this gold standard of care more widely available. Inspiring in its possibilities, radical in its conclusions, The Age of Scientific Wellness shares actionable insights to help you chart a course to a longer, healthier, and more fulfilling life.
Although books exist on the evolution of aging, this is the first book written from the perspective of again as an adaptive program. It offers an insight into the implications of research on aging genetics, The author proposes the Demographic Theory of Senescence, whereby aging has been affirmatively selected because it levels the death rate over time helping stabilize population dynamics and prevent extinctions.
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. |
