Immunology Improving on Nature in the Twenty-First Century
notion at the time, one that challenged existing concepts of how proteins conformed to the shapes of other interacting proteins. Nevertheless, the clonal selection the-molecular understanding of how the diverse repertoire of antigen receptors is generated came with the studies of Susumu Tonegawa in the 1970s (Tonegawa et al., 1977). Based on this work, and its many subsequent refinements, it is...
متن کاملThe Nature of Self-Improving Artificial Intelligence
Self-improving systems are a promising new approach to developing artificial intelligence. But will their behavior be predictable? Can we be sure that they will behave as we intended even after many generations of selfimprovement? This paper presents a framework for answering questions like these. It shows that self-improvement causes systems to converge on an
متن کاملImproving on Nature: James Travis' Work on Recombinant Human α1-Proteinase Inhibitor.
In 1985, when recombinant DNA technology was still in its infancy, James Travis at the University of Georgia and colleagues developed a nonoxidizable form of a protein critical for preventing emphysema. Emphysema is an obstructive lung disease caused by progressive destruction of the lung tissue. The researchers synthesized the natural and variant forms of the protein through a partnership with...
متن کاملImproving Nature ? : the Science and Ethics of Genetic Engineering
Improving Nature? is guided by a simple set of premises t h a t the science o f genetic engineering is essential to discussing its ethics and, moreover, that a coherent set o f ethical principles cannot be developed solely from scientific comprehension. This stance is sensible, if not selfevident, in the examination o f any new technology. 3 The authors, Michael Reiss, a biologist at Cambridge ...
متن کاملImproving the spatial coherence of nature areas using genetic algorithms
Habitat fragmentation and habitat loss are causing many species to become locally extinct. The need to restore or conserve biodiversity has initiated plans in Europeöand, more specifically, in the Netherlandsöto create networks of nature areas for the improvement of spatial coherence. In this paper spatial coherence is measured by the total boundary length of all nature areas. Spatial optimizat...
