Aquifer Microbes Survive on Hydrogen and Carbon Dioxide Diet
DCO Research Aquifer Microbes Survive on Limited Diet

Bacteria living on the surface of the mineral olivine inside a deep, subseafloor aquifer rely on the Wood-Ljungdahl pathway, an ancient type of metabolism that uses hydrogen and carbon dioxide to…

arly Extinctions Set the Stage for Life as We Know It
DCO Research Extinctions Set the Stage for Life Today

By applying data science techniques to the fossil record, researchers have found evidence for two early extinction events that wiped out the strange organisms populating Earth during the Ediacaran…

DCO Research Simulating chemistry under extreme conditions

A new book edited by Nir Goldman covers several computational approaches to simulate a range of chemical reactions relevant to deep carbon science, from prebiotic chemistry that led to the origin of…

DCO Research Methane Metabolism is Ancient and Widespread

By searching existing metagenomic data to find genes for a key methane metabolism enzyme, researchers identified new and diverse groups of archaea capable of producing or consuming methane. The…

DCO Research Gas Monitoring Warns of Wet Eruptions

DCO researchers used MultiGAS stations and flying drones to monitor gas emissions at Poás volcano in Costa Rica, a “wet” volcano that interacts with a hydrothermal system. They observed clear changes…

Deep Life Not Limited to Microbes: Earthquakes Move Surface Animals to the Deep
DCO Research Earthquakes Move Animals to the Deep

Researchers propose that seismic activity transports freshwater animals into the subsurface along fractures in the rock. This activity could explain the presence of nematodes and other small animals…

Earth First Origins Project Seeks To Replicate the Cradle of Life
DCO Highlights Replicating the Cradle of Life

NASA’s Astrobiology Program has awarded a $9 million grant to a research team led by Karyn Rogers, to investigate the environments and conditions on Earth that led to the origin of life.

DCO Highlights Deep Energy Community Convenes for Final Meeting

Deep Energy (DE) community Chair Isabelle Daniel (Université Lyon1, France) and co-chair Edward Young (University of California, Los Angeles, USA) brought together 37 members of the community in th

DCO Research Endospores Rival Growing Cells in Sediments

A survey of ocean sediments from around the world finds that dormant bacterial endospores are about as common as slow-growing cells, and make up a significant portion of the total microbial biomass,…

In Earth’s Magma Ocean, Carbon Chemistry Got Complicated
DCO Research Complicated Carbon Chemistry in Magma Ocean

Computer simulations of the magma ocean on early Earth suggest that the carbon chemistry was surprisingly complex at high pressure. Iron likely sequestered much of the carbon into the metallic core…

DCO Research Introducing Hydrothermarchaeota

Researchers used cutting-edge molecular methods to describe a group of subseafloor microbes that thrive in the hot, oxygen-free fluids flowing through Earth’s crust.
