Janet Jansson and Christer Jansson of PNNL have each been awarded a NASA grant to explore how life adapts and changes during spaceflight.

The microbial communities within the loose, friable aggregations of organic and mineral components in soil are highly organized spatially, shaped in part by the structure of the soil itself.

Nitrogen is a critical nutrient regulating productivity in many ecosystems and influences nutrient availability by affecting organic matter decomposition rates.

Biogeochemical activity in the hyporheic zone (HZ), sediments where the flowing waters of a river mix with shallow groundwater, supports many of the biological processes that occur within a watershed.

Turbulent vertical fluxes of heat, water vapor, and carbon dioxide (CO2) occur constantly between land surfaces and the atmosphere.

Co-authors of a paper in Hydrological Processes led by PNNL researchers Zhangshuan Hou, Timothy Scheibe, and Christopher Murray, produced a map that identifies different classes of sediments which compose the riverbed along the Hanford ...

A multi-institutional team of scientists developed a new sensitivity analysis framework using Bayesian Networks to quantify which parameters and processes in complex multi-physics models are least understood.

Reactive transport models (RTMs) are used to describe and predict the distribution of chemicals in time and space, in both marine and terrestrial (surface and near-surface) environments where microbially-mediated processes govern...

Hydrologic exchange flows (HEFs) increase the contact between river water and subsurface sediments thereby playing a critical role in biogeochemical and ecological functions along river corridors.

Hydrologic exchange fluxes (HEFs) between rivers and surrounding subsurface environments strongly influence water temperatures and biogeochemical processes. Yet, quantitative measures of their effects on the strength and direction of such e

CME investigators Daniel Martin (Yale) and Samantha Johnson (PNNL) received a team science award at the 2019 Energy Frontier Research Centers (EFRC) Principal Investigators' Meeting in Washington, D.C. in July 2019.

Prof. Yogesh (Yogi) Surendranath of the Center for Molecular Electrocatalysis (CME) was honored with a Presidential Early Career Award for Scientists and Engineers.

Despite a breadth of research on carbon accrual and persistence in soils, scientist lack a strong, general understanding of the mechanisms through which soil organic carbon (SOC) is destabilized in soils. In a new review article, researcher

Nitrogen oxides, also known as NOx, form when fossil fuels burn at high temperatures. When emitted from industrial sources such as coal power plants, these pollutants react with other compounds to produce harmful smog.

Researchers are seeking to better understand how nitrogenase acts as a catalyst to break down nitrogen.

Soil microbial communities are made of networks of interacting species that dynamically reorganize in a changing environment. Understanding how such microbiomes are organized in nature is important for designing or controlling them in the f

Soil microbiomes are among the most diverse microbial communities on Earth. They also play an immense role in cycling soil carbon, nitrogen, and other nutrients that underpin the terrestrial food web.

Researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory and Kansas State University found that soil drying significantly affected the structure and function of soil microbial communities.

The first phase, which started in 2014, generated foundational data from developing mouse and human lungs, created a web portal for public data sharing, and established a repository of human lung tissues.

Egbert and Zucker were two of 62 contributors, in addition to the consortium’s leadership and working group.
