This book surveys the models for the origin of life and presents a new model starting with shaped droplets and ending with life as polygonal Archaea; it collects the most published micrographs of Archaea (discovered only in 1977), which support this conclusion, and thus provides the first visual survey of Archaea. Origin of Life via Archaea’s purpose is to add a new hypothesis on what are called “shaped droplets”, as the starting point, for flat, polygonal Archaea, supporting the Vesicles First hypothesis. The book contains over 6000 distinct references and micrographs of 440 extant species of Archaea, 41% of which exhibit polygonal phenotypes. It surveys the intellectual battleground of the many ideas of the origin of life on earth, chemical equilibrium, autocatalysis, and biotic polymers. This book contains 17 chapters, some coauthored, on a wide range of topics on the origin of life, including Archaea’s origin, patterns, and species. It shows how various aspects of the origin of life may have occurred at chemical equilibrium, not requiring an energy source, contrary to the general assumption. For the reader’s value, its compendium of Archaea micrographs might also serve many other interesting questions about Archaea. One chapter presents a theory for the shape of flat, polygonal Archaea in terms of the energetics at the surface, edges and corners of the S-layer. Another shows how membrane peptides may have originated. The book also includes a large table of most extant Archaea, that is searchable in the electronic version. It ends with a chapter on problems needing further research. Audience This book will be used by astrobiologists, origin of life biologists, physicists of small systems, geologists, biochemists, theoretical and vesicle chemists.

An introduction to the physics of living organisms The field of biophysics employs the principles of physics to study biological systems, and introduces the concept of the living state. It is a multidisciplinary approach to the study of the living state combining physics, biochemistry, molecular and cell biology, medicine and engineering. The physics of macromolecules and macromolecular assemblies is a particularly important aspect of this broader field. Biophysics: Physical Processes Underlying the living state offers an introduction to the general principles of the living state and their biological applications. Beginning with an historical overview of fundamental scientific theories and fields, the book then provides a brief introduction to cell biology and biochemistry, and then an overview of basic thermodynamics, kinetics, information theory, electrostatics in solution, fluid mechanics and macromolecular physics, and their relationship to the living state. After a presentation of physical methods, with an emphasis on light scattering, different biological macromolecules, selected aspects of their functions, and their physical properties and interactions are surveyed. A brief introduction to vision, biomotion, and theoretical biology is also provided. Exploration of some frontier issues in prebiotic origins of life, consciousness, and astrobiology round out the book. The result is a multifaceted window into the broad and evolving field of biophysics. Biophysics readers will also find: Problems at the conclusion of each chapter to reinforce and focus student knowledge A gathering of topics in basic physics and physical chemistry which are seldom found in a single source This textbook is suitable for physics and engineering students studying biophysics, macromolecular science, and biophysical chemistry, as well as for polymer scientists, chemists, biochemists, cell and molecular biologists, bioengineers, and others.

Uniting the conceptual foundations of the physical sciences and biology, this groundbreaking multidisciplinary book explores the origin of life as a planetary process. Combining geology, geochemistry, biochemistry, microbiology, evolution and statistical physics to create an inclusive picture of the living state, the authors develop the argument that the emergence of life was a necessary cascade of non-equilibrium phase transitions that opened new channels for chemical energy flow on Earth. This full colour and logically structured book introduces the main areas of significance and provides a well-ordered and accessible introduction to multiple literatures outside the confines of disciplinary specializations, as well as including an extensive bibliography to provide context and further reading. For researchers, professionals entering the field or specialists looking for a coherent overview, this text brings together diverse perspectives to form a unified picture of the origin of life and the ongoing organization of the biosphere.

New Frontiers in Astrobiology presents a simple and concise overview of the emerging field of astrobiology. Astrobiology studies the evolution, origin, and future of life on Earth and beyond. This book provides a brief overview of the current research and future status of this fascinating field. The book covers a wide range of topics from the history of astrobiology, the big bang, prebiotic chemistry, theories of the origin of life, extreme environments on Earth, and the quest for intelligent life in space. Currently, there is a critical gap in knowledge related to the future scope of astrobiology and its applications in science and society. The hallmark of the book is that it takes critical perspectives to analyze the new frontiers in astrobiology post Mars 2020/ExoMars missions that encompass the latestdevelopments in the detection of biosignatures and habitability beyond our Solar System (exomoons, exoplanets). The book will be a valuable resource for students, researchers, and scientists who seek greater insights into understanding the current status and future of astrobiology. - Explores the background and historical developments in astrobiology - Provides concise cutting-edge reviews on fundamental questions on origin and distribution of life on Earth, habitability beyond Earth, and future of life on Earth - Integrates contemporary and critical views in new frontiers in astrobiology

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.

This book is written for researchers and students interested in the function and role of chemical elements in biological or environmental systems. Experts have long known that the Periodic System of Elements (PSE) provides only an inadequate chemical description of elements of biological, environmental or medicinal importance. This book explores the notion of a Biological System of the Elements (BSE) established on accurate and precise multi-element data, including evolutionary aspects, representative sampling procedures, inter-element relationships, the physiological function of elements and uptake mechanisms. The book further explores the concept Stoichiometric Network Analysis (SNA) to analyze the biological roles of chemical species. Also discussed is the idea of ecotoxicological identity cards which give a first-hand description of properties relevant for biological and toxicological features of a certain chemical element and its geo biochemically plausible speciation form. The focus of this book goes beyond both classical bioinorganic chemistry and toxicology.
