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

Rodney WeberGeorgia Tech researchers have found it's not just car emissions sending people to emergency rooms in Atlanta, but all that dust coming off brakepads and tires....Georgia Tech’s School of Earth & Atmospheric Sciences professor Rodney Weber said thanks to fewer diesel engines on the road and Environmental Protection Agency (EPA) regulations, air quality has drastically improved in Atlanta in the last 15 years. "But there's still enough sulfate to make it really, really acidic,” Weber said. “It has a pH in Atlanta of probably around 0 to 2, which is like car battery acid." The study was published in Environmental Science and Technology and included research from EAS graduate students Ting Fang, Hongyu Guo, Linghan Zeng and EAS professor Athanasio Nenes.
