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

Mark Hay, Regents Professor and Harry and Linda Teasley Chair in the School of Biological SciencesTiny, camouflaged snails are harming coral reefs already vulnerable to degradation from rising sea temperatures, overfishing and pollution. Biologist Mark Hay and others at the Georgia Institute of Technology discovered groups of thumbnail-sized snails preying on the coral species Porites cylindrica by sucking their fluid like a tick, and found that they can reduce coral growth by up to 43 percent in less than a month.
