Thanks Pat I will do that..... Already found the CME site for definitions and internet learning. Wonder if the printed package is any different then what's available on line....will have to ask. Here's something to fix your Neural Nets>>smile<< The next technology 'Machine' Crafted Out of DNA By RICK CALLAHAN The Associated Press Scientists have used strands of DNA to build a moving part, a step toward tiny ''machines'' that could someday be used to construct computer circuits and clear clogged blood vessels in the brain. The bending, hinge-like part is just four-ten-thousandths of the width of a human hair. It isn't the first time scientists have turned chemical compounds into moving parts, but previous examples have been hampered by their floppiness. The DNA device is particularly rigid, lead researcher Nadrian Seeman said. The device was made by joining two double-stranded DNA spirals with a bridge of DNA. When it's exposed to a particular chemical solution, part of the structure bends. The findings were reported in today's issue of the journal Nature by Seeman and colleagues at New York University. The team hopes to eventually build other moving parts using DNA, including ''arms'' and ''fingers'' that someday could be mounted on a micro-robot. The work is the latest twist in the fledgling field of nanotechnology, or technology at an atomic scale. ''This is a very beautiful demonstration of construction at that scale of a device that's actually functioning,'' said Daniel Colbert of Rice University's Center for Nanoscale Science and Technology. However, Colbert said scientists are still decades away from creating any useful machines in nanotechnology. ''We're kind of in the children's playtime toddler era of doing this. We've been thrown some blocks and Legos and Tinker Toys,'' he said. ''We're just kind of picking them up and trying to assemble things out of them that can perform something useful.'' K. Eric Drexler of the Institute for Molecular Manufacturing in Los Altos, Calif., agreed that Seeman's device is too cumbersome to be useful. But he said further development may lead to a practical device. AP-NY-01-14-99 0129EST
