Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice called clathrates trap methane gas, preventing it from escaping and bubbling up into the atmosphere. Until now, the biological process behind how methane gas remains stable under the sea has been almost completely unknown. In a breakthrough study, a cross-disciplinary team of Georgia Tech researchers discovered a previously unknown class of bacterial proteins that play a crucial role in the formation and stability of methane clathrates. College of Sciences team members include Jennifer Glass, associate professor in the School of Earth and Atmospheric Sciences; Raquel Lieberman, professor and Sepcic-Pfeil Chair in the School of Chemistry and Biochemistry; Dustin Huard, a researcher in Lieberman’s lab and first author of the study;  Abigail Johnson, a former Ph.D. student in Glass’ lab and co-first author on the paper, and James (JC) Gumbart, professor in the School of Physics. (The study was also covered at India Education Diary, SciTechDaily, Space.com, and Astrobiology.)
