This book celebrates the dawn of the rye genomics era with concise, comprehensive, and accessible reviews on the current state of rye genomic research, written by experts in the field for students, researchers and growers. To most, rye is the key ingredient in a flavoursome bread or their favourite American whisky. To a farmer, rye is the remarkable grain that tolerates the harshest winters and the most unforgiving soils, befitting its legacy as the life-giving seed that fed the ancient civilisations of northern Eurasia. Since the mid-1900s, scientists have employed genetic approaches to better understand and utilize rye, but only since the technological advances of the mid-2010s has the possibility of addressing questions using rye genome assemblies become a reality. Alongside the secret of its unique survival abilities, rye genomics has accelerated research on a host of intriguing topics such as the complex history of rye’s domestication by humans, the nature of genes that switch fertility on and off, the function and origin of accessory chromosomes, and the evolution of selfish DNA.
The U.S. Department of Energy (DOE) promotes scientific and technological innovation to advance the national, economic, and energy security of the United States. Recognizing the potential of microorganisms to offer new energy alternatives and remediate environmental contamination, DOE initiated the Genomes to Life program, now called Genomics: GTL, in 2000. The program aims to develop a predictive understanding of microbial systems that can be used to engineer systems for bioenergy production and environmental remediation, and to understand carbon cycling and sequestration. This report provides an evaluation of the program and its infrastructure plan. Overall, the report finds that GTL's research has resulted in and promises to deliver many more scientific advancements that contribute to the achievement of DOE's goals. However, the DOE's current plan for building four independent facilities for protein production, molecular imaging, proteome analysis, and systems biology sequentially may not be the most cost-effective, efficient, and scientifically optimal way to provide this infrastructure. As an alternative, the report suggests constructing up to four institute-like facilities, each of which integrates the capabilities of all four of the originally planned facility types and focuses on one or two of DOE's mission goals. The alternative infrastructure plan could have an especially high ratio of scientific benefit to cost because the need for technology will be directly tied to the biology goals of the program.
Throughout the world, closely related species are found on landmasses separated by wide stretches of ocean. What explains these far-flung distributions? Why are such species found where they are across the Earth? Since the discovery of plate tectonics, scientists have conjectured that plants and animals were scattered over the globe by riding pieces of ancient supercontinents as they broke up. In the past decade, however, that theory has foundered, as the genomic revolution has made reams of new data available. And the data has revealed an extraordinary, stranger-than-fiction story that has sparked a scientific upheaval. In The Monkey’s Voyage, biologist Alan de Queiroz describes the radical new view of how fragmented distributions came into being: frogs and mammals rode on rafts and icebergs, tiny spiders drifted on storm winds, and plant seeds were carried in the plumage of sea-going birds to create the map of life we see today. In other words, these organisms were not simply constrained by continental fate; they were the makers of their own geographic destiny. And as de Queiroz shows, the effects of oceanic dispersal have been crucial in generating the diversity of life on Earth, from monkeys and guinea pigs in South America to beech trees and kiwi birds in New Zealand. By toppling the idea that the slow process of continental drift is the main force behind the odd distributions of organisms, this theory highlights the dynamic and unpredictable nature of the history of life. In the tradition of John McPhee’s Basin and Range, The Monkey’s Voyage is a beautifully told narrative that strikingly reveals the importance of contingency in history and the nature of scientific discovery.
Supernumerary B chromosomes (Bs) are dispensable genetic elements found in thousands of species of plants and animals, and some fungi. Since their discovery more than a century ago, they have been a source of puzzlement, as they only occur in some members of a population and are absent from others. When they do occur, they are often harmful, and in the absence of “selfishness”, based on mechanisms of mitotic and meiotic drive, there appears to be no obvious reason for their existence. Cytogeneticists have long wrestled with questions about the biological existence of these enigmatic elements, including their lack of any adaptive properties, apparent absence of functional genes, their origin, sequence organization, and co-evolution as nuclear parasites. Emerging new technologies are now enabling researchers to step up a gear, to look enthusiastically beyond the previous limits of the horizon, and to uncover the secrets of these “silent” chromosomes. This book provides a comprehensive guide to theoretical advancements in the field of B chromosome research in both animal and plant systems.

This publication provides an update on the current status of gene maps in different livestock and pet/companion animal species. The findings summarized in species specific commentaries and original articles testify the rapid advances made in the field of animal genomics. Of significant interest is the fact that current investigations are providing headways for two important and exciting research fronts: targeted high-resolution mapping leading to the application of genomic information in addressing questions of economic and biological significance in animals, and the initiation of whole genome sequencing projects for some of the animal species. Like in humans and mice, this will set the stage for a new level of research and real time complex analysis of the genomes of these species. Animal Genomics signifies the beginning of a new era in this field and celebrates the achievements of the past 20 years of genomics research. It will be of special interest to researchers involved in genome analysis - both gross chromosomal as well as molecular - in various animal species, and to comparative and evolutionary geneticists.

The dynamic Hong Kong, officially the Hong Kong Special Administrative Region of the People's Republic of China, is a largely self-governing territory of the People's Republic of China (PRC), facing the Guangdong Province in the north and the South China Sea to the east, west and south. Under the "one country, two systems" policy, Hong Kong enjoys considerable autonomy in all areas with the exception of foreign affairs and defense (which are the responsibility of the PRC Government). As part of this arrangement, Hong Kong continues to maintain its own currency, separate legal, political systems and other aspects that concern its way of life, many of which are distinct from those of mainland China. In relation with the title of this proceeding, Biological and Medical Engineering, Developmental biology, Environmental Biology, Evolutionary Biology, Marine Biology, Chemistry and Chemical Engineering Fundamentals, Chemical engineering educational challenges and development, Chemical reaction engineering, Chemical engineering equipment design and process design, Thermodynamics, Catalysis & reaction engineering, Advances in computational & numerical methods, Systems biology, Integration of Life Sciences & Engineering, Multi-scale and Multi-disciplinary Approaches, Controlled release of the active ingredient, Energy & nuclear sciences, Energy and environment, CFD & chemical engineering, Food engineering etc, has been targeted and included in this proceeding. The proceeding is the results of the contribution of a number of experts from the international scientific community in the respective field of research.
Children are already learning at birth, and they develop and learn at a rapid pace in their early years. This provides a critical foundation for lifelong progress, and the adults who provide for the care and the education of young children bear a great responsibility for their health, development, and learning. Despite the fact that they share the same objective - to nurture young children and secure their future success - the various practitioners who contribute to the care and the education of children from birth through age 8 are not acknowledged as a workforce unified by the common knowledge and competencies needed to do their jobs well. Transforming the Workforce for Children Birth Through Age 8 explores the science of child development, particularly looking at implications for the professionals who work with children. This report examines the current capacities and practices of the workforce, the settings in which they work, the policies and infrastructure that set qualifications and provide professional learning, and the government agencies and other funders who support and oversee these systems. This book then makes recommendations to improve the quality of professional practice and the practice environment for care and education professionals. These detailed recommendations create a blueprint for action that builds on a unifying foundation of child development and early learning, shared knowledge and competencies for care and education professionals, and principles for effective professional learning. Young children thrive and learn best when they have secure, positive relationships with adults who are knowledgeable about how to support their development and learning and are responsive to their individual progress. Transforming the Workforce for Children Birth Through Age 8 offers guidance on system changes to improve the quality of professional practice, specific actions to improve professional learning systems and workforce development, and research to continue to build the knowledge base in ways that will directly advance and inform future actions. The recommendations of this book provide an opportunity to improve the quality of the care and the education that children receive, and ultimately improve outcomes for children.
In The Genome Odyssey, Dr. Euan Ashley, Stanford professor of medicine and genetics, brings the breakthroughs of precision medicine to vivid life through the real diagnostic journeys of his patients and the tireless efforts of his fellow doctors and scientists as they hunt to prevent, predict, and beat disease. Since the Human Genome Project was completed in 2003, the price of genome sequencing has dropped at a staggering rate. It’s as if the price of a Ferrari went from $350,000 to a mere forty cents. Through breakthroughs made by Dr. Ashley’s team at Stanford and other dedicated groups around the world, analyzing the human genome has decreased from a heroic multibillion dollar effort to a single clinical test costing less than $1,000. For the first time we have within our grasp the ability to predict our genetic future, to diagnose and prevent disease before it begins, and to decode what it really means to be human. In The Genome Odyssey, Dr. Ashley details the medicine behind genome sequencing with clarity and accessibility. More than that, with passion for his subject and compassion for his patients, he introduces readers to the dynamic group of researchers and doctor detectives who hunt for answers, and to the pioneering patients who open up their lives to the medical community during their search for diagnoses and cures. He describes how he led the team that was the first to analyze and interpret a complete human genome, how they broke genome speed records to diagnose and treat a newborn baby girl whose heart stopped five times on the first day of her life, and how they found a boy with tumors growing inside his heart and traced the cause to a missing piece of his genome. These patients inspire Dr. Ashley and his team as they work to expand the boundaries of our medical capabilities and to envision a future where genome sequencing is available for all, where medicine can be tailored to treat specific diseases and to decode pathogens like viruses at the genomic level, and where our medical system as we know it has been completely revolutionized.
