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 […]
Ainara Sistiaga interviewed for #STEMStories
Excerpt: “I always liked history and human evolution, the mysteries of our history were my passion as a kid, but also liked a lot nature and Earth history. In college I decided to study history, with a major in Prehistory. From my freshman year I joined a archaeological excavation on Neanderthals. There I discovered you […]
Ring by Ring
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 […]

Summons Lab at EATS!
On Friday, November 1st, Angel Mojarro and Roger Summons shared research summaries of their work to the MIT EAPS community as part of the EAPS Active Talk Series. Angel spoke about soft tissue preservation in fossil fish, while Roger spoke about soft tissue preservation and pigments in an ankylosaur fossil, as well as gut microbiome […]
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 […]
The Summons Lab presents at IMOG 2019
Six members of the Summons Lab traveled from Cambridge, Massachusetts to Göteborg, Sweden, to present their ongoing research at the International Meeting of Organic Geochemistry. The meeting, which takes place every two years, hosts organic geochemists from around the world, and features a combination of talks, posters, and opportunities for colleagues to connect. All Summons […]
August
This summer, the Summons Lab welcomed two visiting students, Nan Sun and Yongli Li, from the University of Science and Technology of China. After weeks of labwork and analyses, the two presented their summer work to the lab group. Nan worked closely with Gareth Izon, and presented her research titled “Questioning the Paradigm of Earth’s […]
Congratulations, Jorsua!
