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.

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