Living Matter

This survey was written at the invitation of the Editors of the "Ergebnisse der Physiologie". Its aim is to present the more recent progress in the know ledge of biological energy transformations. Since it was intended for a review journal, the reader was taken to be familiar with the fundamentals of current biochemistry, as described in the standard textbooks. It was not the object to compile an extensive collection of facts. The survey is limited to aspects of wider interest, and the main emphasis has been on the general unifying principles which emerge from the great mass of detailed ob servations. The article is reprinted in the hope that it may be useful in this form to advanced students and research workers in biochemistry and related subjects. H. A. KREBS H. L.

This innovative volume is the first to address the conservation of contemporary art incorporating biological materials such as plants, foods, bodily fluids, or genetically engineered organisms. Eggshells, flowers, onion peels, sponge cake, dried bread, breast milk, bacteria, living organisms—these are just a few of the biological materials that contemporary artists are using to make art. But how can works made from such perishable ingredients be preserved? And what logistical, ethical, and conceptual dilemmas might be posed by doing so? Because they are prone to rapid decay, even complete disappearance, biological materials used in art pose a range of unique conservation challenges. This groundbreaking book probes the issues associated with displaying, collecting, and preserving these unique works of art. The twenty-four papers from the conference present a range of case studies, prominently featuring artists’ perspectives, as well as conceptual discussions, thereby affording a comprehensive and richly detailed overview of current thinking and practices on this topic. Living Matter is the first publication to explore broadly the role of biological materials in the creative process and present a variety of possible approaches to their preservation. The free online edition of this open-access publication is available at www.getty.edu/publications/living-matter/ and includes videos and zoomable illustrations. Also available are free PDF, EPUB, and Kindle/MOBI downloads of the book.

This book, by an eminent scientist and philosopher, provides strong evidence for the claim that language is a general principle of Nature, rooted exclusively in physical and chemical laws. The author’s radical idea inevitably leads us to view the essence, origin and evolution of life in a completely new light. It shifts the coordinates of our scientific world-view in favor of an overarching concept of language that is able to bridge the gap between matter and mind. At the same time, it removes a blind spot in the Darwinian concept of evolution. To justify this far-reaching idea, the book takes a long and deep look at our scientific and philosophical thinking, at language as such, at science’s claim to truth, and at its methods, unity, limits and perspectives. These are the cornerstones structuring the book into six thematically self-contained chapters, rounded off by an epilogue that introduces the new topic of Nature’s semantics. The range of issues covered is a testimony to how progress in the life sciences is transforming the whole edifice of science, from physics to biology and beyond. The book is aimed at a broad academic and general readership; it requires no mathematical expertise.

Ever since 1911, the Solvay Conferences have shaped modern physics. The format is quite different from other conferences as the emphasis is placed on discussion. The 27th edition held in October 2017 in Brussels and chaired by Boris Shraiman continued this tradition and addressed some of the most pressing open questions in the fields of biophysics, gathering many of the leading figures working on a wide variety of profound problems.The proceedings contain the 'rapporteur talks' giving a broad overview with unique insights by distinguished renowned scientists. These lectures cover the five sessions: 'Intra-cellular Structure and Dynamics', 'Cell Behavior and Control', 'Inter-cellular Interactions and Patterns', 'Morphogenesis', 'Evolutionary dynamics'.In the Solvay tradition, the proceedings also include the prepared comments to the rapporteur talks. The discussions among the participants — expert, yet lively and sometimes contentious — have been edited to retain their flavor and are reproduced in full. The reader is taken on a breathtaking ride through a fascinating field which is expanding rapidly and which was for the first time the subject of a Solvay Conference on Physics.

A preeminent physicist unveils a field-defining theory of the origins and purpose of life. Why are we alive? Most things in the universe aren't. And everything that is alive traces back to things that, puzzlingly, weren't. For centuries, the scientific question of life's origins has confounded us. But in Every Life Is on Fire, physicist Jeremy England argues that the answer has been under our noses the whole time, deep within the laws of thermodynamics. England explains how, counterintuitively, the very same forces that tend to tear things apart assembled the first living systems. But how life began isn't just a scientific question. We ask it because we want to know what it really means to be alive. So England, an ordained rabbi, uses his theory to examine how, if at all, science helps us find purpose in a vast and mysterious universe. In the tradition of Viktor Frankl's Man's Search for Meaning, Every Life Is on Fire is a profound testament to how something can come from nothing.
