This article, recently published in the Christian Science Monitor, discusses the work of Prof. Nadrian Seeman of NYU ( http://www.nyu.edu/search/directory?base=All&query=nadrian+seeman&submit=Search ) in creating a "nanoscale factory worker". True to the nature of newpapers (in this case, the online only version; the CSM stopped printing hard copies last year) Dr. Seeman’s work is not explored in the depth that one would have liked. Instead, Dr. Seeman’s work in creating industrial nanobots is glossed over. A few images pop into mind reading this article, of a nano-size robot Maria being brought to life as in Fritz Lang’s "Metropolis" ( http://en.wikipedia.org/wiki/Metropolis_(1927_movie) or of a nano Sally Fields holding up a sign saying "Union" ( http://en.wikipedia.org/wiki/Norma_Rae ).
