Download or read book Icons of Life written by Lynn Morgan and published by Univ of California Press. This book was released on 2009-09-09 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Icons of Life tells the engrossing and provocative story of an early twentieth-century undertaking, the Carnegie Institution of Washington's project to collect thousands of embryos for scientific study. Lynn M. Morgan blends social analysis, sleuthing, and humor to trace the history of specimen collecting. In the process, she illuminates how a hundred-year-old scientific endeavor continues to be felt in today's fraught arena of maternal and fetal politics. Until the embryo collecting project-which she follows from the Johns Hopkins anatomy department, through Baltimore foundling homes, and all the way to China-most people had no idea what human embryos looked like. But by the 1950s, modern citizens saw in embryos an image of "ourselves unborn," and embryology had developed a biologically based story about how we came to be. Morgan explains how dead specimens paradoxically became icons of life, how embryos were generated as social artifacts separate from pregnant women, and how a fetus thwarted Gertrude Stein's medical career. By resurrecting a nearly forgotten scientific project, Morgan sheds light on the roots of a modern origin story and raises the still controversial issue of how we decide what embryos mean.
Download or read book The Biopolitics of Embryos and Alphabets written by Ruth Austin Miller and published by Oxford University Press. This book was released on 2017 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades there has been an explosion in work in the social and physical sciences describing the similarities between human and nonhuman as well as human and non-animal thinking. In this work, Ruth Miller argues that these types of phenomena are also useful models for thinking about the growth, reproduction, and spread of political thought and democratic processes. By shifting her level of analysis from the politics of self-determining subjects to the realm of material environments and information systems, Miller asks what might happen if these alternative, nonhuman thought processes become the normative thought processes of democratic engagement.
Download or read book The Molecular Biology of Insect Disease Vectors written by J.M. Crampton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Only one generation ago, entomology was a proudly isolated discipline. In Comstock Hall, the building of the Department of Entomology at Cornell University where I was first introduced to experimental science in the laboratory of Tom Eisner, those of us interested in the chemistry of life felt like interlopers. In the 35 years that have elapsed since then, all of biology has changed, and entomology with it. Arrogant molecular biologists and resentful classical biologists might think that what has happened is a hostile take-over of biology by molecular biology. But they are wrong. More and more we now understand that the events were happier and much more exciting, amounting to a new synthesis. Molecular Biology, which was initially focused on the simplest of organisms, bacteria and viruses, broke out of its confines after the initial fundamental questions were answered - the structure of DNA, the genetic code, the nature of regulatory genes - and, importantly, as its methods became more and more generally applicable. The recombinant DNA revo lution of the 1970s, the development of techniques for sequencing macromolecules, the polymerase chain reaction, new molecular methods of genetic analysis, all brought molecular biology face to face with the infinite complexity and the exuber ant diversity of life. Molecular biology itself stopped being an isolated diScipline, pre occupied with the universal laws of life, and became an approach to addressing fas cinating specific problems from every field of biology.
Download or read book Models written by Soraya de Chadarevian and published by Stanford University Press. This book was released on 2004 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now that '3-D models’ are so often digital displays on flat screens, it is timely to look back at the solid models that were once the third dimension of science. This book is about wooden ships and plastic molecules, wax bodies and a perspex economy, monuments in cork and mathematics in plaster, casts of diseases, habitat dioramas, and extinct monsters rebuilt in bricks and mortar. These remarkable artefacts were fixtures of laboratories and lecture halls, studios and workshops, dockyards and museums. Considering such objects together for the first time, this interdisciplinary volume demonstrates how, in research as well as in teaching, 3-D models played major roles in making knowledge. Accessible and original chapters by leading scholars highlight the special properties of models, explore the interplay between representation in two dimensions and three, and investigate the shift to modelling with computers. The book is fascinating reading for anyone interested in the sciences, medicine, and technology, and in collections and museums.

Download or read book Plastic Reason written by Tobias Rees and published by Univ of California Press. This book was released on 2016-05-03 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the twentieth century, neuronal researchers knew the adult human brain to be a thoroughly fixed and immutable cellular structure, devoid of any developmental potential. Plastic Reason is a study of the efforts of a few Parisian neurobiologists to overturn this rigid conception of the central nervous system by showing that basic embryogenetic processesÑmost spectacularly the emergence of new cellular tissue in the form of new neurons, axons, dendrites, and synapsesÑcontinue in the mature brain. Furthermore, these researchers sought to demonstrate that the new tissues are still unspecific and hence literally plastic, and that this cellular plasticity is constitutive of the possibility of the human. Plastic Reason, grounded in years of fieldwork and historical research, is an anthropologistÕs account of what has arguably been one of the most sweeping events in the history of brain researchÑthe highly contested effort to consider the adult brain in embryogenetic terms. A careful analysis of the disproving of an established truth, it reveals the turmoil that such a disruption brings about and the emergence of new possibilities of thinking and knowing.

Download or read book In Situ Hybridization written by David G. Wilkinson and published by OUP Oxford. This book was released on 1998-11-26 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: In situ hybridization is used to reveal the location of specific nucleic acids sequences on chromosomes or in tissues. Visualization of the location of genes on chromosomes or of specific mRNAs or viruses in tissues is crucial for understanding the organization, regulation, and function of genes. It is a therefore a core technique in all areas of biomedical research. In Situ Hybridization: A Practical Approach 2/e is the second edition of one of the most successful Practical Approach books, published in 1992. Since the first edition was published, a number of important technical advances have been made. The new edition has been thoroughly updated to contain protocols detailing the major techniques of in situ hybridization currently in use: in situ hybridization to mRNA with oligonucleotide and RNA probes (radiolabelled and hapten labelled); analysis using light and electron microscopes; whole mount in situ hybridization; double detection of RNAs, and RNA plus protein; and fluorescent in situ hybridization to detect chromosomal sequences. The protocols are complemented by advice on strategies for successful results, descriptions of the theoretical basis of in situ hybridization and important new developments in gene expression databases. The procedures described are widely applicable to many systems. The use of in situ hybridization in PCR is covered in a separate volume: Herrington and O'Leary (Eds) PCR 3 - PCR in situ hybridization: A Practical Approach (OUP, 1997). All the authors have extensive practical experience of establishing reliable techniques of in situ hybridization. This book will be useful to all researchers at all levels who use in situ hybridization.
Download or read book Life Before Birth The Moral and Legal Status of Embryos and Fetuses written by Albany Bonnie Steinbock Associate Professor of Philosophy & Public Policy State University of New York and published by Oxford University Press, USA. This book was released on 1992-07-23 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly a day passes without newspaper coverage of some new development regarding prenatal life. The abortion debate continues to rage, but other examples abound: forced Caesareans; prosecutions of women for drug use during pregnancy; fetal protection policies; the use of fetal tissue for transplantation; embryo research; and the disposition of frozen embryos. All of these issues raise the question of the moral status of the unborn: are embryos and fetuses part of the pregnant woman or are they persons? Are they sources of tissue, research tools, or are they pre-born children? Different conceptions of the unborn prevail in different contexts, giving rise to the charge of inconsistency. For example, women have been criminally charged with abusing their fetuses by using drugs during pregnancy, even though abortion--which pro-lifers call the ultimate child abuse--is legal. The legalization of abortion itself was based in part on the unborn's never having been recognized in law as a full legal person. Yet fetuses have been considered as persons for the purposes of insurance coverage, wrongful death suits, and vehicular homicide. This book provides a framework for thinking clearly and coherently about the unborn. The first chapter elaborates the book's basic idea, that all and only beings who have interests have moral standing, and only beings who possess conscious awareness have interests. This thesis, which is called "the interest view," raises issues of considerable philosophical complexity, but is presented in language non-philosophers will be able to understand. Subsequent chapters apply the interest view, and explore the moral and legal aspects of a wide range of issues, including abortion, the legal status of the fetus outside abortion, maternal-fetal conflict, fetal research, and the use and disposition of extracorporeal embryos resulting from the new reproductive technologies. The philosophical discussion is enlivened by examples and actual cases which immediately catch, and sustain, the reader's interest. Written in a lively style, Life Before Birth: The Moral and Legal Status of Embryos and Fetuses is a timely and important work that enables us to resolve contradictions in our current thinking about the unborn, and to approach new issues in a clear and rational manner.
Download or read book The Form of Becoming written by Janina Wellmann and published by MIT Press. This book was released on 2017-04-28 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: An examination of the constitutive role of rhythm and movement in the visualization of developing life. In The Form of Becoming Janina Wellmann offers an innovative understanding of the emergence around 1800 of the science of embryology and a new notion of development, one based on the epistemology of rhythm. She argues that between 1760 and 1830, the concept of rhythm became crucial to many fields of knowledge, including the study of life and living processes. She juxtaposes the history of rhythm in music theory, literary theory, and philosophy with the concurrent turn in biology toward understanding the living world in terms of rhythmic patterns, rhythmic movement, and rhythmic representations. Common to all these fields was their view of rhythm as a means of organizing time—and of ordering the development of organisms. With The Form of Becoming, Wellmann, a historian of science, has written the first systematic study of visualization in embryology. Embryological development circa 1800 was imagined through the pictorial technique of the series, still prevalent in the field today. Tracing the origins of the developmental series back to seventeenth-century instructional graphics for military maneuvers, dance, and craft work, The Form of Becoming reveals the constitutive role of rhythm and movement in the visualization of developing life.
Download or read book Molecular Methods in Developmental Biology written by Matt Guille and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process whereby a single cell, the fertilized egg, develops into an adult has fascinated for centuries. Great progress in understanding that process, h- ever, has been made in the last two decades, when the techniques of molecular biology have become available to developmental biologists. By applying these techniques, the exact nature of many of the interactions responsible for forming the body pattern are now being revealed in detail. Such studies are a large, and it seems ever-expanding, part of most life-science groups. It is at newcomers to this field that this book is primarily aimed. A number of different plants and animals serve as common model org- isms for developmental studies. In Molecular Methods in Developmental Bi- ogy: Xenopus and Zebrafish, a range of the molecular methods applicable to two of these organisms are described, these are the South African clawed frog, Xenopus laevis, and the zebrafish, Brachydanio rerio. The embryos of both of these species develop rapidly and externally, making them particularly suited to investigations of early vertebrate development. However, both Xenopus and zebrafish have their own advantages and disadvantages. Xenopus have large, robust embryos that can be manipulated surgically with ease, but their pseudotetraploidy and long generation time make them unsuitable candidates for genetics. This disadvantage may soon be overcome by using the diploid Xenopus tropicalis, and early experiments are already underway. The transp- ent embryos of zebrafish render them well-suited for in situ hybridization and immunohistochemistry, and good for observing mutations in genetic screens.

Download or read book Protocol for Somatic Embryogenesis in Woody Plants written by Shri Mohan Jain and published by Springer Science & Business Media. This book was released on 2005-08-26 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc. This has put immense pressure on the world’s supplies of trees and raw material to industry and will continue to do so as long as human population continues to grow. Also, the quality of human diet, especially nutritional components, is adversely affected due to limited genetic improvement of most of fruit trees. Thus there is an immediate need to increase productivity of trees. Improvement has been made through conventional breeding methods, however, conventional breeding is very slow due to long life cycle of trees. A basic strategy in tree improvement is to capture genetic gain through clonal propagation. Clonal propagation via organogenesis is being used for the production of selected elite individual trees. However, the methods are labour intensive, costly, and produce low volumes. Genetic gain can now be captured through somatic embryogenesis. Formation of embryos from somatic cells by a process resembling zygotic embryogenesis is one of the most important features of plants. In 1958, Reinert in Germany and Steward in USA independently reported somatic embryogenesis in carrot cultures. Since then, tremendous progress in somatic embryogenesis of woody and non-woody plants has taken place. It offers a potentially large-scale propagation system for superior clones.
Download or read book Current Frontiers in Cryobiology written by Igor Katkov and published by BoD – Books on Demand. This book was released on 2012-03-09 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost a decade has passed since the last textbook on the science of cryobiology, Life in the Frozen State, was published. Recently, there have been some serious tectonic shifts in cryobiology which were perhaps not seen on the surface but will have a profound effect on both the future of cryobiology and the development of new cryopreservation methods. We feel that it is time to revise the previous paradigms and dogmas, discuss the conceptually new cryobiological ideas, and introduce the recently emerged practical protocols for cryopreservation. The present books, "Current Frontiers in Cryobiology" and "Current Frontiers in Cryopreservation" will serve the purpose. This is a global effort by scientists from 27 countries from all continents and we hope it will be interesting to a wide audience.
