Book excerpt: Conrad Hal Waddington's Organisers and Genes, published in 1940, is a summary of available research and theoretical framework for many concepts related to tissue differentiation in the developing embryo. The book is composed of two main conceptual sections. The first section explores the action and nature of the organizer, while the second section delves into genes and their influence on development. In this book Waddington explored organizers in terms of their capacity and method of induction. First he examined the nature of induction, discussing crucial experiments concerning the organizer, including Hans Spemann's discovery of the organizer, and his own research into organizers in higher birds and mammals. Waddington separated the action of the organizer into two distinct categories, evocation and individuation, discussed below. The main experimental approach discussed in this book involved grafting organizing tissue from one embryo or region of an embryo to another. Waddington described evocation as non-assimilative induction, or a one-way inducing signal. He presented this as a chemical signal and illustrated evocation with the dead organizer experiment. The dead organizer was shown to be capable of inducing differentiation of neural tissue in the ectoderm. He also included chemical induction by estrogens and steroids as other evocative signals. An important aspect of any signal of evocation, as presented by Waddington, is that the signal is specific to the differentiation of a certain tissue type.

Download or read book Beyond the Gene written by Jan Sapp and published by Oxford University Press. This book was released on 1987-05-14 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope and significance of cytoplasmic inheritance has been the subject of one of the longest controversies in the history of genetics. In the first major book on the history of this subject, Jan Sapp analyses the persistent attempts of investigators of non-Mendelian inheritance to establish their claims in the face of strong resistance from nucleo-centric geneticists and classical neo-Darwinians. A new perspective on the history of genetics is offered as he explores the conflicts which have shaped theoretical thinking about heredity and evolution throughout the century: materialism vs. vitalism, reductionism vs. holism, preformation vs. epigenesis, neo-Darwinism vs. new-Lamarckism, and gradualism vs. saltationism. In so doing, Sapp highlights competitive struggles for power among individuals and disciplinary groups. He accepts that political interests and general social contexts may directly affect scientific ideas, but develops the stronger thesis that social interests inside science itself are always involved in the content of scientific knowledge. He goes on to show that there are no neutral judges in scientific controversies and investigates the social strategies and methodological rhetoric used by scientists when they defend or oppose a particular theory. At the same time, Sapp illustrates the social constraints that ensure the high cost and risk of entertaining unorthodox theories in the sciences.

Book excerpt: “If you liked Chaos, you’ll love Complexity. Waldrop creates the most exciting intellectual adventure story of the year” (The Washington Post). In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell—and what the origin of life some four billion years ago can tell us about the process of technological innovation today. This book is their story—the story of how they have tried to forge what they like to call the science of the twenty-first century. “Lucidly shows physicists, biologists, computer scientists and economists swapping metaphors and reveling in the sense that epochal discoveries are just around the corner . . . [Waldrop] has a special talent for relaying the exhilaration of moments of intellectual insight.” —The New York Times Book Review “Where I enjoyed the book was when it dove into the actual question of complexity, talking about complex systems in economics, biology, genetics, computer modeling, and so on. Snippets of rare beauty here and there almost took your breath away.” —Medium “[Waldrop] provides a good grounding of what may indeed be the first flowering of a new science.” —Publishers Weekly

Download or read book Human Genome Editing written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-08-13 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genome editing is a powerful new tool for making precise alterations to an organism's genetic material. Recent scientific advances have made genome editing more efficient, precise, and flexible than ever before. These advances have spurred an explosion of interest from around the globe in the possible ways in which genome editing can improve human health. The speed at which these technologies are being developed and applied has led many policymakers and stakeholders to express concern about whether appropriate systems are in place to govern these technologies and how and when the public should be engaged in these decisions. Human Genome Editing considers important questions about the human application of genome editing including: balancing potential benefits with unintended risks, governing the use of genome editing, incorporating societal values into clinical applications and policy decisions, and respecting the inevitable differences across nations and cultures that will shape how and whether to use these new technologies. This report proposes criteria for heritable germline editing, provides conclusions on the crucial need for public education and engagement, and presents 7 general principles for the governance of human genome editing.
Download or read book The Sciences of the Artificial reissue of the third edition with a new introduction by John Laird written by Herbert A. Simon and published by MIT Press. This book was released on 2019-08-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbert Simon's classic work on artificial intelligence in the expanded and updated third edition from 1996, with a new introduction by John E. Laird. Herbert Simon's classic and influential The Sciences of the Artificial declares definitively that there can be a science not only of natural phenomena but also of what is artificial. Exploring the commonalities of artificial systems, including economic systems, the business firm, artificial intelligence, complex engineering projects, and social plans, Simon argues that designed systems are a valid field of study, and he proposes a science of design. For this third edition, originally published in 1996, Simon added new material that takes into account advances in cognitive psychology and the science of design while confirming and extending the book's basic thesis: that a physical symbol system has the necessary and sufficient means for intelligent action. Simon won the Nobel Prize for Economics in 1978 for his research into the decision-making process within economic organizations and the Turing Award (considered by some the computer science equivalent to the Nobel) with Allen Newell in 1975 for contributions to artificial intelligence, the psychology of human cognition, and list processing. The Sciences of the Artificial distills the essence of Simon's thought accessibly and coherently. This reissue of the third edition makes a pioneering work available to a new audience.
Download or read book Evolution in Four Dimensions revised edition written by Eva Jablonka and published by MIT Press. This book was released on 2014-03-21 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: A pioneering proposal for a pluralistic extension of evolutionary theory, now updated to reflect the most recent research. This new edition of the widely read Evolution in Four Dimensions has been revised to reflect the spate of new discoveries in biology since the book was first published in 2005, offering corrections, an updated bibliography, and a substantial new chapter. Eva Jablonka and Marion Lamb's pioneering argument proposes that there is more to heredity than genes. They describe four “dimensions” in heredity—four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Jablonka and Lamb present a richer, more complex view of evolution than that offered by the gene-based Modern Synthesis, arguing that induced and acquired changes also play a role. Their lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points. Each chapter ends with a dialogue in which the authors refine their arguments against the vigorous skepticism of the fictional “I.M.” (for Ipcha Mistabra—Aramaic for “the opposite conjecture”). The extensive new chapter, presented engagingly as a dialogue with I.M., updates the information on each of the four dimensions—with special attention to the epigenetic, where there has been an explosion of new research. Praise for the first edition “With courage and verve, and in a style accessible to general readers, Jablonka and Lamb lay out some of the exciting new pathways of Darwinian evolution that have been uncovered by contemporary research.” —Evelyn Fox Keller, MIT, author of Making Sense of Life: Explaining Biological Development with Models, Metaphors, and Machines “In their beautifully written and impressively argued new book, Jablonka and Lamb show that the evidence from more than fifty years of molecular, behavioral and linguistic studies forces us to reevaluate our inherited understanding of evolution.” —Oren Harman, The New Republic “It is not only an enjoyable read, replete with ideas and facts of interest but it does the most valuable thing a book can do—it makes you think and reexamine your premises and long-held conclusions.” —Adam Wilkins, BioEssays
Download or read book The Strategy of the Genes written by C.H. Waddington and published by Routledge. This book was released on 2014-04-29 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1957, this essential classic work bridged the gap between analytical and theoretical biology, thus setting the insights of the former in a context which more sensitively reflects the ambiguities surrounding many of its core concepts and objectives. Specifically, these five essays are concerned with some of the major problems of classical biology: the precise character of biological organisation, the processes which generate it, and the specifics of evolution. With regard to these issues, some thinkers suggest that biological organisms are not merely distinguishable from inanimate ‘things’ in terms of complexity, but are in fact radically different qualitatively: they exemplify some constitutive principle which is not elsewhere manifested. It is the desire to bring such ideas into conformity with our understanding of analytical biology which unifies these essays. They explore the contours of a conceptual framework sufficiently wide to embrace all aspects of living systems.
Download or read book Nature Remade written by Luis A. Campos and published by University of Chicago Press. This book was released on 2021-07-16 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Engineering” has firmly taken root in the entangled bank of biology even as proposals to remake the living world have sent tendrils in every direction, and at every scale. Nature Remade explores these complex prospects from a resolutely historical approach, tracing cases across the decades of the long twentieth century. These essays span the many levels at which life has been engineered: molecule, cell, organism, population, ecosystem, and planet. From the cloning of agricultural crops and the artificial feeding of silkworms to biomimicry, genetic engineering, and terraforming, Nature Remade affirms the centrality of engineering in its various forms for understanding and imagining modern life. Organized around three themes—control and reproduction, knowing as making, and envisioning—the chapters in Nature Remade chart different means, scales, and consequences of intervening and reimagining nature.
