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

A new report from across the pond finds that airborne particulate pollution from tire wear and tear can be more than 1,000 times worse than what comes out of a tailpipe, depending on what substances are being measured. In 2017, researchers at the Georgia Institute of Technology, including Rodney Weber and Hongyu Guo, found that fine metals emitted from brakes and tires combine with acidic sulfate in the atmosphere to produce a toxic, soluble aerosol.
