Human reproductive cloning is an assisted reproductive technology that would be carried out with the goal of creating a newborn genetically identical to another human being. It is currently the subject of much debate around the world, involving a variety of ethical, religious, societal, scientific, and medical issues. Scientific and Medical Aspects of Human Reproductive Cloning considers the scientific and medical sides of this issue, plus ethical issues that pertain to human-subjects research. Based on experience with reproductive cloning in animals, the report concludes that human reproductive cloning would be dangerous for the woman, fetus, and newborn, and is likely to fail. The study panel did not address the issue of whether human reproductive cloning, even if it were found to be medically safe, would beâ€"or would not beâ€"acceptable to individuals or society.
Meet Fisher Bas: 12 years-old, growth-stunted, a geeky science genius, and son of the Nobel Prize-winning creators of the Bas-Hermaphrodite-Sea-Slug-Hypothesis. No surprise: Fisher isn't exactly the most popular kid in his middle-school, tormented daily by the beefy, overgrown goons he calls The Vikings. But he senses relief when he comes upon the idea of cloning himself—creating a second Fisher to go to school each day while he stays at home playing video games and eating cheetos with ketchup. It's an ingenious plan that works brilliantly, until Fisher's clone turns out to be more popular than him—and soon after gets clone-napped by the evil scientist Dr. Xander. Can Fischer save his clone in time, or will his whole plan be exposed?
Luke Taylor's true nature has been revealed, but his fight to rescue his wife and newborn daughter is just beginning. Now that Beta and the second generation of clones have been unleashed, can Luke survive against his younger, stronger, and more ruthless selves?
Someday soon, if it hasn't happened in secret already, the first cloned human will be born and mankind will embark on a scientific and moral journey whose destination cannot be foretold. In A Clone of Your Own?, Arlene Judith Klotzko describes the new world of possibilities that can be glimpsed over the horizon. In a lucid and engaging narrative, she explains that the technology to create clones of living beings already exists, inaugurated in 1996 by Dolly the sheep, the first mammal cloned from a single adult cell. Our fascination with cloning is about much more than science and its extraordinary medical implications. In riveting prose, full of allusions to art, music, and the cinema, Klotzko shows why the prospect of human cloning triggers our dearest hopes and especially our darkest fears, forcing us to ponder anew what it means to be human, and what it would be like to have 'a clone of your own'.
Duplicated passages of source code - code clones - are a common property of software systems. While clones are beneficial in some situations, their presence causes various problems for software maintenance. Most of these problems are strongly related to change and include, for example, the need to propagate changes across duplicated code fragments and the risk of inconsistent changes to clones that are meant to evolve identically. Hence, we need a sophisticated analysis of clone evolution to better understand, assess, and manage duplication in practice. This thesis introduces Clone Evolution Graphs as a technique to model clone relations and their evolution within the history of a system. We present our incremental algorithm for efficient and automated extraction of Clone Evolution Graphs from a system's history. The approach is shown to scale even for large systems with long histories making it applicable to retroactive analysis ofclone evolution as well as live tracking of clones during software maintenance.We have used Clone Evolution Graphs in several studies to analyze versatile aspects of clone evolution in open-source as well as industrial systems. Our results show that the characteristics of clone evolution are quite different between systems, highlighting the need for a sophisticated technique like Clone Evolution Graphs to track clones and analyze their evolution on a per-system basis. We have also shown that Clone Evolution Graphs are well-suited to analyze the change behavior of individual clones and can be used to identify problematic clones within a system. In general, the results of our studies provide new insights into how clones evolve, how they are changed, and how they are removed.
Acclaimed authors Patricia C. McKissack and Frederick L. McKissack have collaborated with their son, John, to deliver a searing novel. In the year 2170 an underground abolitionist movement fights for the freedom of cyborgs and clones, who are treated no better than slaves. Original.
This book provides in-depth explorations of genetic cloning, including the history of cloning and the types of artificial cloning for both plants and animals, with fascinating examples. It also explains the possibility of using the gene therapy to cure diseases.
Everyone wants the clone created. The scientist, to advance her theories. The Russian gangster, for supposedly he is the one being cloned. The Russian gangster’s sons, for they know the real reason. The scientist’s husband, for he wants her to be happy. But what is she cloning, really? They gave her the cells, the lab, an assistant, a host, and money enough to not ask questions. What are they hiding? From the depths of South Africa to the cold of Russia, the clone will pull you in every direction. And when you think you have it figured out, something takes a turn. Protect yourself, for this story may even be true. The Clone, by Johan Thompson. Only ask questions for which you want answers.
Animal cloning has developed quickly since the birth of Dolly the sheep. Yet many of the first questions to be raised still need to be answered. What do Dolly and her fellow mouse, cow, pig, goat and monkey clones mean for science? And for society? Why do so many people respond so fearfully to cloning? What are the ethical issues raised by cloning animals, and in the future, humans? How are the makers of public policy coping with the stunning fact that an entire animal can be reconstructed from a single adult cell? And that humans might well be next? The Cloning Source Book addresses all of these questions in a way that is unique in the cloning literature, by grounding what is effectively an interdisciplinary conversation in solid science. In the first section of the book, the key scientists responsible for the early and crucial developments in cloning speak to us directly, and other scientists evaluate and comment on these developments. The second section explores the context of cloning and includes sociological, mythological, and historical perspectives on science, ethics, and policy. The authors also examine the media's treatment of the Dolly story and its aftermath, both in the United States and in Britain. The third section, on ethics, contains a broad range of papers written by some of the major commentators in the field. The fourth section addresses legal and policy issues. It features individual and collective contributions by those who have actually shaped public policy on reproductive cloning, therapeutic cloning, and similarly contentious bioethical issues in the United States, Britain, and the European Union. Animal cloning continues for agricultural and medicinal purposes, the latter in combination with transgenics. Human cloning for therapeutic purposes has recently been made legal in Britain. The goal is to produce an early embryo and then derive stem cells that are immunologically matched to the donor. Two human reproductive cloning projects have been announced, and there are almost certainly others about which we know nothing. Sooner or later a cloned human will be born. Many lessons can be learned from the cloning experience. Most importantly, there needs to be a public conversation about the permissible uses of new and morally murky technologies. Scientists, journalists, ethicists and policy makers all have roles to play, but cutting-edge science is everybody's business. The Cloning Sourcebook provides the tools required for us to participate in shaping our own futures.
