Water is unlike other substances because its solid form — like this iceberg — is less dense than its liquid form — like this ocean. Scientists are studying other weird properties of water.

Oil spills could be cleaned up in the icy, rough waters of the Arctic with a chemically modified sawdust material that absorbs up to five times its weight in oil and stays afloat for at least four months.

PNNL's Morris Bullock and Jud Virden selected as fellows of the American Association for the Advancement of Science for achievements that advance science and its applications.

PNNL's Xue Bin Wang has been elected to the rank of fellow of the American Physical Society for his contributions in condensed phase chemical physics.

Six PNNL researchers named to the list of the most highly cited in the world. The list features scientists from around the world whose citations rank in the top one percent within 22 subject areas.

This mineral helps the oil industry process petroleum. Understanding how it gets clogged up will improve its lifespan.

PNNL tools that track underground contaminants and speed carbon capture technology development are among R&D Magazine's 100 most innovative scientific breakthroughs of the year.

Cybersecurity is increasingly top-of-mind and in the news. Individuals worry about identify theft and the compromise of financial and medical records. And the federal government battles myriad threats aimed at our national security.

Discovery in action. These words describe what we do at PNNL. For more than 50 years, we have advanced the frontiers of science and engineering in the service of our nation and the the world.

Scientists have made a "vitamin mimic" - a molecule that looks and acts just like a natural vitamin to bacteria - that offers a new window into the inner workings of living microbes.

Calcium carbonate found in chalk, shells and rocks is one of the most important materials on earth. New insights on how it turns into hard, strong materials will help scientists design materials needed for a low-carbon future.

At PNNL, scientists have mapped the reaction that turns wind-generated electricity into fuel and the amount of energy needed for each step.

Dr. Morris Bullock and Dr. Monte Helm reviewed the catalysis research at the Center for Molecular Electrocatalysis, where Bullock is the director, in a recent article in Accounts of Chemical Research.
