Book Description
What is a Life? How did it appear? What principles underlie its functioning? Similar questions have accompanied man since birth. People of all ages have tried to answer these questions on the basis of the maturity of the available knowledge and techniques. This is why the theory of evolution preserves, even in modern science, a central role, embracing all the spheres of biology, physics and medicine. The modern concept of evolution is extremely simple; nevertheless, many scientists still show great difficulties in incorporating and integrating this concept into their work. One of the main errors is the assumption that the different species developed along an "evolutionary scale", from bacteria to animals, more or less complex, up to man, which would therefore represent the apex of evolution. Most people, who wish to and are living a long life remaining active and cheerful until old age, are increasingly seeking doctors' help. What is health? Some believe that it is the absence of diseases and physical defects. For some, it is a state of physical, mental and social well-being. However, despite the different definitions of this concept, everyone agrees that health is a leading factor in determining the quality of our lives. Health is influenced by many factors. Some of them improve health others worsen it (risk factors). Some experts have compiled a list of the main factors affecting health and given an indicative assessment of the degree of importance of each of them. This includes lifestyle, environmental influences, quality of medical care and heredity. A physician who regularly observes a given individual has to face challenges that modern medicine hasn't sufficiently researched and developed, assess the individual risk of developing a disease, identify early markers of change leading to disease development and individually select the corrective actions. It should be noted that one of the most important conditions for long-term preservation of health is the development of methods from the earliest possible diagnosis of diseases at the preclinical stage. This book combines the experience of clinical and laboratory research as well as some basic philosophy ideas of a group of scientists who, starting from an individual point of view, were able to synthesize and make available to other colleagues a new way of view of human organism and explaining the events that can trigger pathological conditions, including cancer, autism, diabetes and other chronical diseases.

Book Description
Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Book Description
"Yet another cell and molecular biology book? At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? First, it's a course that I have enjoyed teaching for many years, so I am very familiar with what a student really needs to take away from this class within the time constraints of a semester. Second, because it is a course that many students take, there is a greater opportunity to make an impact on more students' pocketbooks than if I were to start off writing a book for a highly specialized upper- level course. And finally, it was fun to research and write, and can be revised easily for inclusion as part of our next textbook, High School Biology."--Open Textbook Library.

Book Description
Fundamentals of Molecular Structural Biology reviews the mathematical and physical foundations of molecular structural biology. Based on these fundamental concepts, it then describes molecular structure and explains basic genetic mechanisms. Given the increasingly interdisciplinary nature of research, early career researchers and those shifting into an adjacent field often require a "fundamentals" book to get them up-to-speed on the foundations of a particular field. This book fills that niche.

Book Description
All life is chemical. That fact underpins the developing field of ecological stoichiometry, the study of the balance of chemical elements in ecological interactions. This long-awaited book brings this field into its own as a unifying force in ecology and evolution. Synthesizing a wide range of knowledge, Robert Sterner and Jim Elser show how an understanding of the biochemical deployment of elements in organisms from microbes to metazoa provides the key to making sense of both aquatic and terrestrial ecosystems. After summarizing the chemistry of elements and their relative abundance in Earth's environment, the authors proceed along a line of increasing complexity and scale from molecules to cells, individuals, populations, communities, and ecosystems. The book examines fundamental chemical constraints on ecological phenomena such as competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. In accessible prose and with clear mathematical models, the authors show how ecological stoichiometry can illuminate diverse fields of study, from metabolism to global change. Set to be a classic in the field, Ecological Stoichiometry is an indispensable resource for researchers, instructors, and students of ecology, evolution, physiology, and biogeochemistry. From the foreword by Peter Vitousek: ? "[T]his book represents a significant milestone in the history of ecology. . . . Love it or argue with it--and I do both--most ecologists will be influenced by the framework developed in this book. . . . There are points to question here, and many more to test . . . And if we are both lucky and good, this questioning and testing will advance our field beyond the level achieved in this book. I can't wait to get on with it."

Book Description
A journey into the sub-microscopic world of molecular machines. Readers are first introduced to the types of molecules built by cells: proteins, nucleic acids, lipids, and polysaccharides. Then, in a series of distinctive illustrations, the reader is guided through the interior world of cells, exploring the ways in which molecules work in concert to perform the processes of living. Finally, the author shows us how vitamins, viruses, poisons, and drugs each have their effects on the molecules in our bodies. David Goodsell, author and illustrator, has prepared a fascinating introduction to biochemistry for the non-specialist. His book combines a lucid text with an abundance of drawings and computer graphics that present the world of cells and their components in a truly unique way.

Book Description
This book provides an accessible introduction to an exciting new field of life science in which the focus is on small numbers of molecules and minorities within cell populations and their significance for the understanding of biological phenomena. Numbers, or quantitative data, are attracting more attention in cell biology following, for example, determination of the absolute copy number of each protein species in each bacterial cell and the recognition of leader cells that drive collective cell migration. Within this context, the authors present recent advances in experimental techniques, biological findings, and theories. A variety of cutting-edge topics and issues are addressed, with explanation of the ways in which recent developments in the field cast light on seemingly straightforward but difficult-to-answer questions. Readers will learn that we are on the verge of a paradigm shift as the importance of cooperation among groups of molecules in live cells is acknowledged. The book is designed to be enjoyable to read and easy to understand. It will be of interest for a wide range of readers, including young researchers and undergraduate/high school students.
