A stream of photons can affect minuscule objects much like wind turning a windmill. Researchers from the University of Glasgow in Scotland have found a way to use a pair of laser beams to rotate an object in three dimensions, turning it like a ball rather than a wheel. ------ Cold logic promises speedy devices http://www.trnmag.com/Stories/2003/031203/Cold_logic_promises_speedy_devices_B rief_031203.html Researchers from the University of Cambridge and Hitachi Cambridge Laboratory have made a superconducting logic circuit that computes very quickly and requires little power. ------ RNA forms nanomotor http://www.trnmag.com/Stories/2003/031203/RNA_forms_nanomotor_Brief_031203.htm l Researchers from Purdue University have constructed a tiny motor from DNA and RNA molecules. The device, fueled by ATP, which powers our own movements, could eventually power nanomachines. ______________________________________ Jonathan Hinek South Florida ______________________________________ --part1_3f.19a0c0bd.2ba37ec4_boundary Content-Type: text/html; charset="US-ASCII" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=21402
