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

For now, life is flourishing on our oxygen-rich planet, but Earth wasn't always that way – and scientists have predicted that, in the future, the atmosphere will revert back to one that's rich in methane and low in oxygen. This probably won't happen for another billion years or so. But when the change comes, it's going to happen fairly rapidly, a study published in Nature Geosciences earlier this year suggests. That study was co-authored by Chris Reinhard, associate professor in the School of Earth and Atmospheric Sciences.
