World's First Programmable Nanoprocessor: Nanowire Tiles Can Perform Arithmetic and Logical Functions

ScienceDaily (Feb. 9, 2011) — Engineers and scientists collaborating at Harvard University and the MITRE Corporation have developed and demonstrated the world's first programmable nanoprocessor. The groundbreaking prototype computer system, described in a paper appearing in the journal Nature, represents a significant step forward in the complexity of computer circuits that can be assembled from synthesized nanometer-scale components. It also represents an advance because these ultra-tiny nanocircuits can be programmed electronically to perform a number of basic arithmetic and logical functions. "This work represents a quantum jump forward in the complexity and function of circuits built from the bottom up, and thus demonstrates that this bottom-up paradigm, which...

Nissan in New 600,000 Car Recall Edited by Warren Johnson - Nguyen Nam Tran - Sunday, Nov 14, 2010 (Reuters) – Nissan Motor is recalling over 600,000 pickup trucks and cars because of concerns over their steering shafts. About 300,000 Nissan Frontier trucks like this 2001 model and over 280,000 X-terra sport utility vehicles are affected.Around 85% of the recalled makes are in North America. Japan's number three automaker says it discovered that the lower steering column joint in these models can corrode and crack in extreme cases.But Nissan adds there have been no accidents due to this problem. The automaker received three reports of the problem in Canada...
