There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Heat-Sensitive Material Remembers Four Shapes
Live Science - March 10, 2010
A substance called a polymer usually used to make fuel cells can "remember" up to four different shapes, and revert to each one at different temperatures, according to new research. The polymer, or others like it, could be used in fields ranging from biomedical engineering to space exploration... From a scientific standpoint, PFSA is "not a unique chemistry at all," said Ken Gall, a materials scientist from Georgia Tech who was also uninvolved in Xie's work.
