The book is a detailed account of major biological events that contributed to create the present world and our species, with emphasis on cause-effect interrelationships and environmental impact. Its main goal is to guide the reader toward an understanding of the continuity of life across diversity, and of its large-scale interactions with the planet. Combining scientific soundness with a constant effort for clarity, the book begins with a cloud of dust in a corner of the Galaxy and, covering an immense lapse of time, terminates with an organism that ponders about the texture of the Universe. Comprehensive, updated references added to each chapter will help the reader wishing to expand any of the topics. A glossary explains less common technical terms.
This book is a celebration of ideas: how they happen and their sometimes unintended results. Johnson shows how simple scientific breakthroughs have driven other discoveries through the network of ideas and innovations that made each finding possible. He traces important inventions through ancient and contemporary history, unlocking tales of unsung heroes and radical revolutions that changed the world and the way we live in it
Plant breeders have long sought technologies to extend human control over nature. Early in the twentieth century, this led some to experiment with startlingly strange tools like x-ray machines, chromosome-altering chemicals, and radioactive elements. Contemporary reports celebrated these mutation-inducing methods as ways of generating variation in plants on demand. Speeding up evolution, they imagined, would allow breeders to genetically engineer crops and flowers to order. Creating a new food crop or garden flower would soon be as straightforward as innovating any other modern industrial product. In Evolution Made to Order, Helen Anne Curry traces the history of America’s pursuit of tools that could intervene in evolution. An immersive journey through the scientific and social worlds of midcentury genetics and plant breeding and a compelling exploration of American cultures of innovation, Evolution Made to Order provides vital historical context for current worldwide ethical and policy debates over genetic engineering.
As humans evolved, we developed technologies to modify our environment, yet these innovations are increasingly affecting our behavior, biology, and society. Now we must figure out how to function in the world we’ve created. Over thousands of years, humans have invented ingenious ways to gain mastery over our environment. The ability to communicate, accumulate knowledge collectively, and build on previous innovations has enabled us to change nature. Innovation has allowed us to thrive. The trouble with innovation is that we can seldom go back and undo it. We invent, embrace, and exploit new technologies to modify our environment. Then we modify those technologies to cope with the resulting impacts. Gluckman and Hanson explore what happens when we innovate in a way that leads nature to bite back. To provide nourishment for a growing population, humans developed methods to process and preserve food; but easy access to these energy-dense foods results in obesity. To protect ourselves from dangerous pathogens we embraced cleanliness and invented antibiotics, which has led to rising rates of autoimmune diseases and antibiotic-resistant bacteria. More recently, our growing dependence on the internet and social media has been linked to mental health concerns and declining social cohesion. And we are only at the beginning of the digital transformation that will influence every part of our existence. Our ingenuity has not only changed our world—it has changed us. Focusing on immediate benefits, we rarely pause to consider the longer-term costs of innovation. Yet we are now starting to see how our choices affect the way our brains develop and our bodies function. The implications are profound. Ingenious opens our eyes to the dangers we face and offers solutions we cannot ignore.
"Entertaining and prescient…Hockfield demonstrates how nature’s molecular riches may be leveraged to provide potential solutions to some of humanity’s existential challenges." —Adrian Woolfson, Science A century ago, discoveries in physics came together with engineering to produce an array of astonishing new technologies that radically reshaped the world: radios, televisions, aircraft, computers, and a host of still-evolving digital tools. Today, a new technological convergence—of biology and engineering—promises to create the tools necessary to tackle the threats we now face, including climate change, drought, famine, and disease World-renowned neuroscientist and academic leader Susan Hockfield describes the most exciting new developments and the scientists and engineers who helped to create them. Virus-built batteries. Cancer-detecting nanoparticles. Computer-engineered crops. Together, they highlight the promise of the technology revolution of the twenty-first century to overcome some of the greatest humanitarian, medical, and environmental challenges of our time.
Despite the vital importance of the emerging area of biotechnology and its role in defense planning and policymaking, no definitive book has been written on the topic for the defense policymaker, the military student, and the private-sector bioscientist interested in the "emerging opportunities market" of national security. This edited volume is intended to help close this gap and provide the necessary backdrop for thinking strategically about biology in defense planning and policymaking. This volume is about applications of the biological sciences, here called "biologically inspired innovations," to the military. Rather than treating biology as a series of threats to be dealt with, such innovations generally approach the biological sciences as a set of opportunities for the military to gain strategic advantage over adversaries. These opportunities range from looking at everything from genes to brains, from enhancing human performance to creating renewable energy, from sensing the environment around us to harnessing its power.
Biological collections are a critical part of the nation's science and innovation infrastructure and a fundamental resource for understanding the natural world. Biological collections underpin basic science discoveries as well as deepen our understanding of many challenges such as global change, biodiversity loss, sustainable food production, ecosystem conservation, and improving human health and security. They are important resources for education, both in formal training for the science and technology workforce, and in informal learning through schools, citizen science programs, and adult learning. However, the sustainability of biological collections is under threat. Without enhanced strategic leadership and investments in their infrastructure and growth many biological collections could be lost. Biological Collections: Ensuring Critical Research and Education for the 21st Century recommends approaches for biological collections to develop long-term financial sustainability, advance digitization, recruit and support a diverse workforce, and upgrade and maintain a robust physical infrastructure in order to continue serving science and society. The aim of the report is to stimulate a national discussion regarding the goals and strategies needed to ensure that U.S. biological collections not only thrive but continue to grow throughout the 21st century and beyond.
The tremendous progress in biology over the last half century - from Watson and Crick's elucidation of the structure of DNA to today's astonishing, rapid progress in the field of synthetic biology - has positioned us for significant innovation in chemical production. New bio-based chemicals, improved public health through improved drugs and diagnostics, and biofuels that reduce our dependency on oil are all results of research and innovation in the biological sciences. In the past decade, we have witnessed major advances made possible by biotechnology in areas such as rapid, low-cost DNA sequencing, metabolic engineering, and high-throughput screening. The manufacturing of chemicals using biological synthesis and engineering could expand even faster. A proactive strategy - implemented through the development of a technical roadmap similar to those that enabled sustained growth in the semiconductor industry and our explorations of space - is needed if we are to realize the widespread benefits of accelerating the industrialization of biology. Industrialization of Biology presents such a roadmap to achieve key technical milestones for chemical manufacturing through biological routes. This report examines the technical, economic, and societal factors that limit the adoption of bioprocessing in the chemical industry today and which, if surmounted, would markedly accelerate the advanced manufacturing of chemicals via industrial biotechnology. Working at the interface of synthetic chemistry, metabolic engineering, molecular biology, and synthetic biology, Industrialization of Biology identifies key technical goals for next-generation chemical manufacturing, then identifies the gaps in knowledge, tools, techniques, and systems required to meet those goals, and targets and timelines for achieving them. This report also considers the skills necessary to accomplish the roadmap goals, and what training opportunities are required to produce the cadre of skilled scientists and engineers needed.
This work offers a novel way to map evolutionary time from life's origin to the first humans. Rather than using a traditional, linear scale in which events bunch up toward the end, a logarithmic scale is employed that expands our resolution as we come to the present. Such a scale allows us to detect patterns that would otherwise be invisible and arrange evolutionary events in memorable fashion. The basic concept of logarithms is not complicated, as we will simply halve units as we move from the past to the present in order to highlight major evolutionary change. Thus, we find the start of life to be approximately four billion years ago, the nucleated cell at two billion years ago, complex multicellularity at one billion years ago, and so on. Remarkably, we find the major events of evolution, along with the certainty of supporting evidence, to be pulsed with logarithmic regularity. This chart also reveals that each Major Node represents change in three major arenas, making for significant leaps in consciousness, gains in mobility, and increased social connectivity. Come, take this evolutionary journey and discover the surprising pattern of logarithmic time, with changes that would seem to have no end.
