Timing the Speed of Life

Somewhere between 2.3 and 2.5 billion years ago, the Earth experienced a monumental atmospheric shift, setting the stage for complex life to emerge. EAPS researchers are looking for markers in the rock record providing clues as to how and why—and exactly when. By Fatima Husain The accumulation of oxygen in the Earth’s atmosphere marks the […]

A collaboration of current and former EAPS researchers reveals the genes that enable GDGTs to cyclize  by Fatima Husain Nestled within sediments that accumulate in marine environments, a certain class of molecule-sized fossils sneakily record surface water temperature changes over time. For almost two decades, scientists have used these molecules called glycerol dibiphytanyl glycerol tetraether […]

Continuing a Legacy of Antarctic Exploration

by Fatima Husain When Robert F. Scott’s Discovery expedition began their exploration of the Antarctic continent in 1901, they set out to achieve two goals: to geographically and scientifically characterize the regions touched by the Ross Sea. As the group of naval officers and scientists set foot upon the Ross Ice Shelf, they mapped their travels and […]

Welcoming Visiting Student Jaz Millar

For the month of October, Cardiff University research student Jaz Millar will work in the Summons Lab to study the lipid profiles of microbial communities grown under Snowball Earth-like conditions. In her research, Millar studies how life survived and maintained diversity during the Cryogenian period 720-635 million years ago. She investigates the potential of cryoconite […]

Current Role: I work as an organic geochemist for Geoscience Australia (GA), Australia’s governmental geoscientific organisation, based in Canberra. GA can be loosely described as the Australian equivalent of the US Geological Survey. In my day-to-day job, I work in a multi-disciplinary team providing insights into Australia’s energy resource potential. Years in the Summons Lab: I started […]
