You know, when I saw the headline for this story, the words "Weizmann Institute" immediately leaped into my head. It's just that certain something about Weizmann Institute press releases that reminds me of University of Utah press conferences back in the days of Cold Fusion. In any case, the folks at the Weizmann Institute are now claiming to have developed the "trillion would fit in a test tube" DNA computer. http://in.news.yahoo.com/011121/107/199x5.html ----- LONDON (Reuters) - Following Mother Nature's lead, Israeli scientists have built a DNA computer so tiny that a trillion of them could fit in a test tube and perform a billion operations per second with 99.8 percent accuracy. Instead of using figures and formulas to solve a problem, the microscopic computer's input, output and software are made up of DNA molecules -- which store and process encoded information in living organisms. Scientists see such DNA computers as future competitors to for their more conventional cousins because miniaturisation is reaching its limits and DNA has the potential to be much faster than conventional computers. "We have built a nanoscale computer made of biomolecules that is so small you cannot run them one at a time. When a trillion computers run together they are capable of performing a billion operations," Professor Ehud Shapiro of the Weizmann Institute in Israel told Reuters on Wednesday. It is the first programmable autonomous computing machine in which the input, output, software and hardware are all made of biomolecules. Although too simple to have any immediate applications it could form the basis of a DNA computer in the future that could potentially operate within human cells and act as a monitoring device to detect potentially disease-causing changes and synthesise drugs to fix them. The model could also form the basis of computers that could be used to screen DNA libraries in parallel without sequencing each molecule, which could speed up the acquisition of knowledge about DNA. ... -- Eric Michael Cordian 0+ O:.T:.O:.
