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

The drier, warmer autumn weather that’s becoming more common due to climate change may extend summer smog well into the fall in the Southeastern U.S. in the years ahead, according to a study published on Monday.
Research published in the Proceedings of the National Academy of Sciences also suggests a culprit for the smog that many people might not expect: It’s the lush woodlands that give much of the South a lovely green canopy. That’s because of a natural defense mechanism trees use to protect their leaves from drought conditions.
