The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, according to a new study in the journal Nature.

Scientists are exploring the use of deep neural network to interpret highly technical data related to national security, the environment and the cosmos.

Scientist-detectives put themselves to the test.

Organic matter found in vast quantities in oxygen-starved floodplains would yield only minimal energy for hungry microorganisms, which spurn the meal, researchers show in a study in Nature Geoscience.

Like detectives looking for clues, researchers at the Department of Energy's Pacific Northwest National Laboratory have been working for nearly a decade on ways to identify the "fingerprints" of potential chemical threats.

Pointing the finger at chemical criminals: Several scientists from PNNL and other institutions will discuss new methods and approaches at the American Chemical Society's national meeting in San Francisco April 2-6.

PNNL scientists recently gave a crash course on soil to young children at a local elementary school, dishing up the dirt on soil.

Cleaning up Hanford is no easy task: it is one of the world's largest and most complex environmental remediation projects. The nation's top engineering firms are on the job and the Department of Energy's PNNL is helping.

Two teams honored for transferring PNNL developed technologies to market.
