51Asteroid mining — 433 Eros is a stony asteroid in a near Earth orbit Asteroid mining refers to the possibility of exploiting raw materials from asteroids and planetoids in space, including near Earth objects. Minerals and volatiles could be mined from an asteroid… …
52Ligase ribozyme — Ligase RibozymesRNA Ligase ribozymes are the first of several types of synthetic ribozymes produced by in vitro evolution and selection techniques. They are an important class of ribozymes because they catalyze the assembly of RNA fragments into… …
53LIFE SCIENCES — Introduction Biology has become a vast subject which has increasingly merged with traditionally separate disciplines, particularly chemistry and physics. Indeed life sciences is now a more appropriate term than biology. Furthermore the life… …
54technology, history of — Introduction the development over time of systematic techniques for making and doing things. The term technology, a combination of the Greek technē, “art, craft,” with logos, “word, speech,” meant in Greece a discourse on the arts, both… …
55Computer virus — Not to be confused with Malware. A computer virus is a computer program that can replicate itself[1] and spread from one computer to another. The term virus is also commonly but erroneously used to refer to other types of malware, including but… …
56The Culture — is a fictional interstellar anarchist, socialist, and utopian[1][2] society created by the Scottish writer Iain M. Banks which features in a number of science fiction novels and works of short fiction by him, collectively called the Culture… …
57Codd's cellular automaton — A simple configuration in Codd s cellular automaton. Signals pass along wire made of cells in state 1 (blue) sheathed by cells in state 2 (red). Two signal trains circulate around a loop and are duplicated at a T junction onto an open ended… …
58Error threshold (evolution) — The error threshold is a concept in the study of evolutionary biology and population genetics and is concerned with the origins of life, in particular of very early life, before the advent of DNA. The first self replicating molecules were… …
59Implications of nanotechnology — The implications of nanotechnology run the gamut of human affairs from the medical, ethical, mental, legal and environmental, to fields such as engineering, biology, chemistry, computing, materials science, military applications, and… …
60Nobili cellular automata — λG, a minimal self replicating configuration in Nobili cellular automata Nobili cellular automata are a variation of von Neumann cellular automata, in which additional states provide means of memory and the interference free crossing of signal.… …
