This book provides an interdisciplinary review of one of the great unsolved mysteries that has fascinated scientists for over 150 years: the origin of chirality in biomolecules. Current advances in fields as diverse as space exploration, prebiotic chemistry and high-energy physics may help to provide an answer. Important pieces of information will come from observations at the two frontiers of science: outer space and the subatomic world. Observation of distant planets, galaxies, and even actual sampling of celestial objects from beyond the solar system are projects currently underway. At the other end of the spectrum, there are experiments that study the elemental properties of matter, such as symmetry, and interactions with the fundamental forces. Completely revised and updated this new edition once again unifies all the theories of the origin of biomolecular homochirality together in a single source. This complete, interdisciplinary review of an intriguing subject condenses a large and disparate range of contributions from journals in almost every scientific field. The various theories have been organized, interrelated and explained in a unified way. It is fundamental, comprehensive and structured to be accessible for educational purposes.

Based on an American Chemical Society Symposium organized by Professors Glenn Seaborg and Oliver Manuel, this volume provides a comprehensive record of different views on this important subject at the end of the 20th century. They have assembled a blend of highly respected experimentalists and theorists from astronomy, geology, meteoritics, planetology and nuclear chemistry and physics to discuss the origin of elements in the solar system. The intent was to include all points of view and let history judge their validity.

The phylontogenic theory proposes an original understanding of nose, sinus and midface formation and development by looking back in evolution for the first traces of the olfactory organ and then tracing its successive phyletic transformations to become part of the respiratory apparatus and finally the central point of human facial anatomy. Von Baer’s, Darwin’s, Haeckel’s, Garstang’s, Gould’s and Buss’ explorations of parallels between phylogeny and ontogeny help to trace the nose and midface story. The paradigm of existing parallels between ontogeny and phylogeny proves useful both in seeking to understand the holoprosencephalic spectrum of facial malformations (which represent radically different pathways of facial development after the life’s tape has been started to run again) and in formulating hypotheses on chordate to vertebrate evolution. The phylontogenic theory leads to new medical hypotheses on nose and sinus diseases and opens the field of evolution and development-based medicine.

"The hypothesis that music had its origin in the amatory sounds made by the male to charm the female, has the support of the popular idea that the singing of birds constitutes a kind of courtship—an idea adopted by Mr. Darwin when he says that "the male pours forth his full volume of song, in rivalry with other males, for the sake of captivating the female."...

Where do stars come from and how do they form? These are profound questions which link the nature of our Universe to the roots of mankind. Yet, until a recent revolution in understanding, the proposed answers have been raw speculation. Now, accompanying penetrating observations, a new picture has come into prominence. This book presents the latest astounding observations and scientific ideas covering star formation, star birth and early development. It encompasses all aspects, from the dramatic stories of individual objects, to the collective influence of entire stellar systems. The very first stars to come into existence and the nurturing of planets are discussed to provide the reader with a comprehensive overview. Presenting background information with only the essential mathematics, this book will appeal to scientists wishing to expand their horizons, students seeking solid foundations, and general readers with enquiring minds.

Key Features:Presents in concise and readable form the story of star formation, and the revelations that have shaken the foundations of the subjectProvides the knowledge essential for an understanding of the construction of stars of all typesIncludes introductions and summaries that will make the subject accessible to a broad audienceKeywords:Stars;Stellar Evolution;The Universe;Clusters;Protostars;Galaxies;Starbursts;Magnetic Field;Complex Systems;Fluid DynamicsReviews:“This book has a readable style … it should be accessible to readers with a variety of scientific backgrounds, and to advanced undergraduates. It will be particularly useful as an introduction to the subject for first year research students in astrophysics. The book is recommended reading for anyone with an interest in the subject.”Professor David Williams University College London “Overall, this is a good read, and as clear a picture of the field as his target readership is likely to get at the moment. I recommend it as ancillary reading in first- and second-year courses, or as an introduction for a junior-honours course.”The Observatory Magazine

The Origin of Humanness in the Biology of Love

The central concern of this book is us human beings. The authors’ basic question is: ‘How is it that we can live in mutual care, have ethical concerns, and at the same time deny all that through the rational justification of aggression?’ The authors answer this basic question indirectly by providing a look into the fundaments of our biological constitution, concentrating on what they term emotioning, that is the flow of emotions in daily life that guides the flow of the systemic conservation of a manner of living. Maturana and Verden-Zöller claim that the fundamental emotion that gave rise to humans as sapient languaging beings was love, and that this remains our fundament even when other emotions become socially prevalent.

This book is the second volume in the series Livestock Diseases and Management, and reviews the importance and implications of animal origin viral zoonoses. It also highlights the specific etiology and epidemiology of these viral infections and discusses their various biological and mechanical transmission mechanisms. Further, the book reviews various measures for controlling viral zoonoses and examines novel therapeutic and prophylactic strategies. Discussing recent studies on the pathogenesis and host immune response to these infections, it underscores the importance of using vaccines against these viral diseases to reduce the risk of them being transmitted to humans.Lastly, it describes in detail the challenges posed by these viral infections and our readiness to face them.

Recently, new genes and their proteins that revealed striking new insights into the early evolution of multicellular animals have been identified and characterized from members of the lowest metazoan phylum, the porifera (sponges). The unexpected result was that the sequences obtained from sponge displayed high similarity to those found in higher metazoa; in consequence, it was concluded that during the transition from protozoa to metazoa the major structural and regulatory proteins evolved only once. The data gathered are now powerful arguments to establish monophyly of metazoa; in addition, new insights on the evolutionary diversification of metazoa were obtained.

Seventeen-year-old Halah Ibrahim has always known a privileged life and never had cause to question it until Cairo goes up in flames. Not only does she start to doubt her father and his role in the new military-backed government—but she ultimately decides to flee to America with a young soldier she hardly knows, an impulsive act that has far-reaching consequences on both sides of the ocean. A powerful and universal debut novel about family, identity, and independence, Country of Origin is as much about a nation's coming-of-age as it is about secrets and lies, love and truth.
