EVANSTON, Ill., Aug. 14 (UPI) -- A U.S. nanoscientist has created a printing technique capable of mass producing the 2008 Summer Olympics logo 15,000 times in just 1 square centimeter.

NEW YORK, June 30 (UPI) -- A new method to carve infinitesimal gaps into nanowires soon could help scientists connect electronics to single molecules. This in turn could lead to computers based on molecular transistors with vastly greater computing power than conventional machines.

EVANSTON, Ill., Feb. 21 (UPI) -- The combination of molecular-sized electrodes and tiny balls of gold atoms can radically increase the sensitivity and selectivity of DNA tests, researchers from Northwestern University said Thursday.
