The monograph discusses models of synthetic protocells, which are cell-like structures obtained from non-living matter endowed with some rudimentary kind of metabolism and genetics, but much simpler than biological cells. They should grow and proliferate, generating offsprings that resemble in some way the parent protocells with some variation, so that selection may take place. Sustainable protocell populations have not yet been obtained experimentally and mathematical models are therefore extremely important to address key questions concerning their synthesis and behavior. Different protocell “architectures” have been proposed and high-level abstract models like those that are presented in this book are particularly relevant to gain a better understanding of the different properites. These models are able to treat all the major dynamical phenomena in a unified framework, so they can be seen as “virtual laboratories” for protocell research. Particular attention is paid to the problem of synchronization of the fission rate of the whole protocell and the duplication rate of its "protogenetic" material, which is shown to be an emergent property that spontaneously develops in successive generations. The book is of interest for a broad range of scientists working in soft matter physics, chemistry and biology, interested in the role protocells may play on the development of new technologies with medical, environmental and industrial applications as well as scientists interested in the origin of life.

In Assembling Life, David Deamer addresses questions that are the cutting edge of research on the origin of life. For instance, how did non-living organic compounds assemble into the first forms of primitive cellular life? What was the source of those compounds and the energy that produced the first nucleic acids? Did life begin in the ocean or in fresh water on terrestrial land masses? Could life have begun on Mars? The book provides an overview of conditions on the early Earth four billion years ago and explains why fresh water hot springs are a plausible alternative to salty seawater as a site where life can begin. Deamer describes his studies of organic compounds that were likely to be available in the prebiotic environment and the volcanic conditions that can drive chemical evolution toward the origin of life. The book is not exclusively Earth-centric, but instead considers whether life could begin elsewhere in our solar system. Deamer does not propose how life did begin, because we can never know that with certainty. Instead, his goal is to understand how life can begin on any habitable planet, with Earth so far being the only known example.

The general topic of this volume concerns the origin, evolution, distribution, and destiny of life in the Universe. Firstly, it discusses the transition from inert matter to cellular life and its evolution to fully developed intelligent beings, and also the possibility of life occurring elsewhere, particularly in other environments in our own and other solar systems. Secondly, the book explores the role that space missions may play in obtaining further insight into the question of the origin of life. Reviews are included of the research for microorganisms in the solar system and the well-established project for the search for extraterrestrial intelligence. The present work is much broader in its scope than in previous conferences: over one hundred leading scientists have reviewed the entire range of subjects dealt with in these sixty-nine papers. Audience: This book is aimed at advanced students, as well as researchers, in the many areas of basic, earth, and life sciences that contribute to the study of the first steps in the origin of life.

In a book that will profoundly alter the modern discourse on mind and influence the practice of neuromedicine, neurobiologist/neuropsychiatrist, Richard M. Pico unveils a revolutionary new approach to understanding consciousness that pinpoints its origins in the brain. Called “Biological Relativity,” the approach combines the laws of physics—especially Einstein’s laws of relativity—to the latest breakthroughs in neuroscience, molecular biology, and computational theory to create a coherent four-dimensional model for explaining the origins of life and the emergence of complex biological systems—from the living cell to the thinking brain. In a fascinating, ambitious narrative that draws upon a lifetime of experimental and clinical work, Dr. Pico tells a riveting story that begins in the imponderably distant past, with the first proto-cell that endured long enough to become its own frame of reference—both structurally and temporally—and culminates with the most complex biological referent system known to science, the human brain. He then elaborates his groundbreaking theory through discussions of such things as the origins of language, music, and mathematics. He explains why he believes consciousness is uniquely human, and explores the causes and potential treatments for a variety of thought disorders.

"The book covers all major scientific approaches to creating minimal life, both in the laboratory and in simulation. It emphasizes the bottom-up view of physicists, chemists, and material scientists but also includes the molecular biologists' top-down approach and the origin-of-life perspective. The capacity to engineer living technology could have an enormous socioeconomic impact and could bring both good and ill."--BOOK JACKET.

The first work to deal exclusively with objective criteria for comparing statistical models. Using a simple framework, it outlines a general strategy for selecting a model and applies this strategy to develop methods useful for solving specific selection problems. Topics covered include histograms, univariate distributions, simple and multiple regression, the analysis of variance and covariance, the analysis of proportions and contingency tables, time series analysis, and spatial analysis.
