The Science The prediction of rainfall over the Amazon rainforest by weather and climate models is highly uncertain, particularly for large rainstorms which are commonly seen during the wet season, from March to May. Using an advanced object tracking …
The Science The Coastal Observations, Mechanisms, and Predictions Across Systems and Scales: Field, Measurements, and Experiments (COMPASS-FME) project established a network of observational field sites across the Chesapeake Bay and western Lake Erie …
The Science Due to their inherent variability and complexity over space and time, scientists are challenged to understand the complex interactions among soil, vegetation, and water along coastal terrestrial-aquatic interfaces (TAI). This research addresses …
The Science Aerosols are known to affect cloud properties, including their formation, growth, and precipitation, which in turn influences climate over long time scales. Aerosol-cloud interactions (ACI) depend on how their properties change together, yet …
The Science The release of gases from soil is known as soil respiration and understanding how environmental factors influence this process in coastal terrestrial-aquatic interfaces (TAI) remains a significant challenge. Gas efflux in TAI's remains …
Over the last eight years, Patricia Paviet, senior technical advisor at Pacific Northwest National Laboratory (PNNL), has helped the world learn more about advanced nuclear reactors—one webinar at a time. Since 2016, she has organized and moderated more …
The Science Water is at the center of processes ranging from precipitation to digestion. At extreme temperatures, water exhibits unusual behavior that scientists are still attempting to understand. To identify whether amorphous water behaves as a true …
The Science Accurate prediction of streamflow is vital for water resource usage and management. Given the growing complexity of modern hydrological models, a key question arises: How many streamflow observations are needed to reliably estimate model …
Jonathan Barr, senior systems engineer at Pacific Northwest National Laboratory (PNNL), was recently invited to co-present on a panel at the Texas Department of Emergency Management (TDEM) Annual Conference. The panel focused on the relationship and …
In the push for reliable, affordable, and secure energy storage, researchers are exploring new ways to improve batteries. Aqueous batteries, those that use water-based electrolytes, stand out as a promising alternative to traditional energy storage systems …
Science is fun and engaging. That hypothesis was validated by the “oohs and ahhs” of thousands of students at Salmon Summit, hosted in late April 2025 by the Benton Conservation District in partnership with Pacific Northwest National Laboratory (PNNL). …
Generating precise radar images is tough enough on solid ground. Now imagine the challenge of innovating a system that maintains precise radar antenna orientation and control on a wildly pitching, rolling platform in the middle of the ocean. And it must …
When we think of the water on Earth, it’s often easier to focus on the clear boundaries between where it continuously is and where it isn’t: oceans, lakes, and rivers vs. deserts and other dry expanses of land. But what about the spaces in between, where …
More than 25,000 participants from industry, government, academia, and the public recently gathered at the second Special Competitive Studies Project (SCSP) AI for National Competitiveness Expo, held in Washington, D.C., to explore recent developments in …
The U.S. electric grid is powering up for a new era of growth and strength—fueled by rising demand and the increasing use of inverter-connected resources that operate without traditional inertia. Integrating these types of new technologies will help …
RICHLAND, Wash.—A system that detects trace levels of fentanyl, cocaine, explosives and other harmful substances through the air has been created by researchers at the Department of Energy’s Pacific Northwest National Laboratory. New test results of a …
The Office of Employer Support of the Guard and Reserve (ESGR) within the Department of Defense has named Pacific Northwest National Laboratory (PNNL) a recipient of the 2025 Pro Patria Award for Washington State. Presented annually, the award recognizes …
The Science In recent years, considerable research has focused on improving the power conversion efficiency of solar cells. Photovoltaics based on metal halide perovskites, or hybrid organic–inorganic perovskites (HOIPs), have been a primary target. Unlike …
Artificial intelligence (AI) is transforming federal permitting practices and making it easier to conduct environmental reviews—and that comes with potential challenges, opportunities, and a wealth of AI-assisted tools. These were the topics of discussion …
The role of states is increasingly important in our cybersecurity defense strategy. Greater collaboration with government, industry, and education are essential to countering cybersecurity threats. With that goal in mind, the Department of Energy’s Office …
