Penn Library: Science and Engineering Libraries, A Thinking Robot, "Smart" Dust
:: Here's a new STLQ feature: web sites from randomly selected scitech libraries. Browse the site, and perhaps you'll find something interesting that you'll want to use in your home library. First up: Science and Engineering Libraries at U Pennsylvania.
:: Chemists at U Cal San Deigo have announced the development of particles the size of dust, which can sense their environment and assemble in groups. The report will appear shortly in the online edition of PNAS. (From: Roland Piquepaille's Technology Trends)
