Die Entdeckung des aufsehenerregenden Organisatoreffektes bei Amphibien durch den Freiburger Hans SPEMANN (1869 - 1941) und seiner Studentin Hilde MANGOLD (geb. Pröscholdt, 1898 - 1924) stellt den bedeutsamsten Meilenstein in der Entwicklungsbiologie des 20. Jahrhunderts dar. Für SPEMANN war es die Krönung seiner langjährigen Forschungen. Im Jahre 1935 erhielt er hierfür den Nobelpreis für Medizin und Physiologie zugesprochen - als zweiter Biologe nach dem amerikanischen Genetiker Hunt Morgan. Mit der vorliegenden Biographie werden erstmals Lebensweg und wissenschaftlicher Werdegang Hans SPEMANNs auf breiter Quellenbasis skizziert. Umfangreiche Tagebuchnotizen und zahlreiche Briefwechsel mit berühmten Kollegen gewähren dem Leser ebenso neue wie lebendige Informationen über Hans SPEMANN.

Long before scientists at the Roslin Institute in Scotland cloned Dolly the sheep in 1996, American embryologist and aspiring cancer researcher Robert Briggs successfully developed the technique of nuclear transplantation using frogs in 1952. Although the history of cloning is often associated with contemporary ethical controversies, Forgotten Clones revisits the influential work of scientists like Briggs, Thomas King, and Marie DiBerardino, before the possibility of human cloning and its ethical implications first registered as a concern in public consciousness, and when many thought the very idea of cloning was experimentally impossible. By focusing instead on new laboratory techniques and practices and their place in Anglo-American science and society in the mid-twentieth century, Nathan Crowe demonstrates how embryos constructed in the lab were only later reconstructed as ethical problems in the 1960s and 1970s with the emergence of what was then referred to as the Biological Revolution. His book illuminates the importance of the early history of cloning for the biosciences and their institutional, disciplinary, and intellectual contexts, as well as providing new insights into the changing cultural perceptions of the biological sciences after Second World War.

As scientists debated the nature of life in the nineteenth century, two theories predominated: vitalism, which suggested that living things contained a "vital spark," and mechanism, the idea that animals and humans differed from nonliving things only in their degree of complexity. Erik Peterson tells the forgotten story of the pursuit of a Third Way in biology, known by many names, including "the organic philosophy," which gave rise to C. H. Waddington's work in the subfield of epigenetics: an alternative to standard genetics and evolutionary biology that captured the attention of notable scientists from Francis Crick to Stephen Jay Gould. The Life Organic chronicles the influential biologists, mathematicians, philosophers, and biochemists from both sides of the Atlantic who formed Joseph Needham's Theoretical Biology Club, defined and refined Third-Way thinking through the 1930s, and laid the groundwork for some of the most cutting-edge achievements in biology today. By tracing the persistence of organicism into the twenty-first century, this book also raises significant questions about how we should model the development of the discipline of biology going forward.

Georg Von Hevesy 1885 1966 written by Niese, Siegfried and has been published by Principal Verlag this book supported file pdf, txt, epub, kindle and other format this book has been release on with categories.

Georg Karl von Hevesy (1885-1966) wurde in Budapest als fünftes Kind einer wohlhabenden, von deutschsprachigen jüdischen Grund- und Fabrikbesitzern stammenden Familie geboren und durch bedeutende Entdeckungen und Erfindungen in der Physik, der Chemie, der Geologie, der Biologie und der Medizin bekannt. Er entdeckte das Hafnium, begründete die nuklearen Analysenmethoden, die Isotopentrennung, die Nuklearmedizin und die Röntgenfluoreszenzanalyse. Georg von Hevesy kannte das Wesen und die Probleme der unterschiedlichsten Fachdisziplinen und stand in einem achtungsvollen und häufig auch sehr freundschaftlichen Verhältnis zu den großen Wissenschaftlern seiner Zeit, wovon sein reger Briefwechsel Zeugnis ablegt. In dieser Biografie werden die Leistungen gewür-digt und die komplizierten Bedingungen, unter denen sie erzielt wurden, beschrieben. In den vielen Auszügen aus seinen Briefen lernen wir einen Menschen kennen, der auch unter schwierigsten Umständen seinen Humor und seinen Respekt vor seinen Mitmenschen nie verlor.
