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 scientists will discuss their research on more than 100 topics at the annual meeting of the American Geophysical Union in San Francisco next week.

PNNL is supporting today's announcement by the White House about efforts related to soil sustainability by sponsoring research projects through two research initiatives.

The temperature difference between the Southern Great Plains and the ocean produces winds that carry moisture from the Gulf of Mexico to the Great Plains, fueling more intense storms as the climate warms.

Warming temperatures will contribute to the release of carbon into the atmosphere, according to research published today in Nature.

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.

Nuclear power figures prominently in our country's energy portfolio and is essential to our economic and environmental security.

How might getting old—really old—affect the glass waste form chosen to immobilize radioactive waste at the Hanford Site in southeastern Washington state? Researchers are seeking answers from walls containing ancient glass in Europe. These walls, known as hillforts, are defense structures that date as far back as the Bronze Age. The researchers progress is the cover story in the May 2016 American Ceramic Society Bulletin.

PNNL takes pride in advancing scientific frontiers and developing solutions to vexing problems. In particular, we apply our technical expertise to address national needs in security, energy and the environment.

Software that can reason like an analyst and a new way of disinfecting rooms won awards from the Federal Laboratory Consortium.

PNNL researchers have demonstrated a process for the expanded use of lightweight aluminum in cars and trucks at the speed, scale, quality and consistency required by the auto industry.
