Today’s scientists are showing us how stem cells create and repair the human body. Unlocking these secrets has become the new Holy Grail of biomedical research. But behind that search lies a sharp divide, one that has continued for years. Stem cells offer the hope of creating or repairing tissues lost to age, disease, and injury. Yet, because of this ability, stem cells also hold the potential to incite an international biological arms race. The Stem Cell Dilemma illuminates everything you need to know about stem cells, and in this new edition the authors have included up-to-date information on scientific advances with iPS cells, clinical trials that are currently underway, hESC policy that is in the U.S. courts, stem cells and biodefense, developments at the California Institute for Regenerative Medicine, and growing international competition, plus all the basics of what stem cells are and how they work.

A panoramic overview of biotechnologies that can endlessly boost human capabilities and the drastic changes these "superhuman" traits could trigger Biotechnology is moving fast. In the coming decades, advanced pharmaceuticals, bioelectronics, and genetic interventions will be used not only to heal the sick but to boost human physical and mental performance to unprecedented levels. People will have access to pills that make them stronger and faster, informatic devices will interface seamlessly with the human brain, and epigenetic modification may allow people to reshape their own physical and mental identities at will. Until recently, such major technological watersheds--like the development of metal tools or the industrialization of manufacturing--came about incrementally over centuries or longer. People and social systems had time to adapt: they gradually developed new values, norms, and habits to accommodate the transformed material conditions. But contemporary society is dangerously unprepared for the dramatic changes it is about to experience down this road on which it is already advancing at an accelerating pace. The results will no doubt be mixed. People will live longer, healthier lives, will fine-tune their own thought processes, and will generate staggeringly complex and subtle forms of knowledge and insight. But these technologies also threaten to widen the rift between rich and poor, to generate new forms of social and economic division, and to force people to engage in constant cycles of upgrades and boosts merely to keep up. Individuals who boost their traits beyond a certain threshold may acquire such extreme capabilities that they will no longer be recognized as unambiguously human. In this important and timely book, prize-winning historian Michael Bess provides a clear, nontechnical overview of cutting-edge biotechnology and paints a vivid portrait of a near-future society in which bioenhancement has become a part of everyday life. He surveys the ethical questions raised by the enhancement enterprise and explores the space for human agency in dealing with the challenges that these technologies will present. Headed your way over the coming decades: new biotechnologies that can powerfully alter your body and mind. The possibilities are tantalizing: * Rejuvenation therapies offering much longer lives (160 and even beyond) in full vigor and mental acuity * Cognitive enhancement through chemical or bioelectronic means (the rough equivalent of doubling or tripling IQ scores) * Epigenetic tools for altering some of your genetically influenced traits at any point in your lifetime (body shape, athletic ability, intelligence, personality) * Bioelectronic devices for modulating your own brain processes, including your "pleasure centers" (a potentially non-stop high) * Direct control of machines by thought, and perhaps direct communication with other people, brain-to-brain (a new dimension of sharing and intimacy) But some of the potential consequences are also alarming: * A growing rift between the biologically enhanced and those who can't afford such modifications * A constant cycle of upgrades and boosts as the bar of "normal" rises ever higher--"Humans 95, Humans XP, Humans 8" * The fragmentation of humankind into rival "bioenhancement clusters" * A gradually blurring boundary between "person" and "product" * Extreme forms of self-modification, with some individuals no longer recognized as unambiguously human From the Hardcover edition.

Scholars and policymakers alike agree that innovation in the biosciences is key to future growth. The field continues to shift and expand, and it is certainly changing the way people live their lives in a variety of ways. With a large share of federal research dollars devoted to the biosciences, the field is just beginning to live up to its billing as a source of innovation, economic productivity and growth. Vast untapped potential to imagine and innovate exists in the biosciences given new tools now widely available. In The Biologist's Imagination, William Hoffman and Leo Furcht examine the history of innovation in the biosciences, tracing technological innovation from the late eighteenth century to the present and placing special emphasis on how and where technology evolves. Place is often key to innovation, from the early industrial age to the rise of the biotechnology industry in the second half of the twentieth century. The book uses the distinct history of bioinnovation to discuss current trends as they relate to medicine, agriculture, energy, industry, ecosystems, and climate. Fast-moving research fields like genomics, synthetic biology, stem cell research, neuroscience, bioautomation and bioprinting are accelerating these trends. Hoffman and Furcht argue that our system of bioscience innovation is itself in need of innovation. It needs to adapt to the massive changes brought about by converging technologies and the globalization of higher education, workforce skills, and entrepreneurship. The Biologist's Imagination is both a review of past models for bioscience innovation and a forward-looking, original argument for what future models should take into account.

Dieses Buch betrifft uns alle Sie waren notwendig, um Fortschritte gegen Krebs und AIDS zu erzielen. Klonen und Genforschung wäre ohne sie nicht möglich gewesen. Kurz: Die größten Erfolge der Medizin der letzten Jahrzehnte basieren auf der Entdeckung der HeLa-Zellen. Hinter dem Kürzel verbirgt sich eine Frau namens Henrietta Lacks. Die Afroamerikanerin aus ärmlichen Verhältnissen starb 1951 jung an Gebärmutterhalskrebs. Zuvor wurden ihr ohne ihr Wissen Zellproben entnommen, die sich überraschenderweise vermehrten. Damit war der entscheidende Durchbruch in der Zellkulturforschung geschafft. Die prämierte Wissenschaftsjournalistin Rebecca Skloot stellt in ihrem brillant verfassten Buch wichtige Jahrzehnte der Medizingeschichte vor und wirft dabei immer wieder ethische Fragen auf. Sie erzählt die tragische Familiengeschichte der Lacks’, die von Rassismus und mangelnden Bildungschancen geprägt ist. Ihr Buch ist eine gekonnte Mischung aus Biografie, Medizingeschichte, Debattenbuch und beachtlichem Enthüllungsjournalismus.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

Ein großer Sportplatz, freundliche Klassenzimmer und getrennte Schlafsäle für Jungen und Mädchen – auf den ersten Blick scheint Hailsham ein ganz gewöhnliches englisches Internat zu sein. Aber die Lehrer, so engagiert und freundlich sie auch sind, heißen hier Aufseher, und sie lassen die Kinder früh spüren, dass sie für eine besondere Zukunft ausersehen sind. Dieses Gefühl hält Kathy, Ruth und Tommy durch alle Stürme der Pubertät und Verwirrungen der Liebe zusammen – bis es an der Zeit ist, ihrer wahren Bestimmung zu folgen.
