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

Methane-making microbes may have battled “rust-breathing” microbes for dominance in early Earth’s oceans—and kept those oceans from freezing under an ancient, dimmer sun in the process, new research suggests....“The ancestors of modern methane-making and rust-breathing microbes may have long battled for dominance in habitats largely governed by iron chemistry,” says Marcus Bray, a biology doctoral candidate in the laboratory of Jennifer Glass, assistant professor in the Georgia Institute of Technology’s School of Earth and Atmospheric Sciences. Glass was the principal investigator for the Georgia Tech research team, which included professors Frank Stewart and Tom DiChristina, postdoctoral scholars Jieying Wu and Cecilia Kretz, Ph.D candidate Keaton Belli, and M.S. student Ben Reed.
