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.

PNNL's Ruby Leung and Johannes Lercher elected to membership in the National Academy of Engineering.

Using a natural catalyst from bacteria for inspiration, researchers have now reported the fastest synthetic catalysts to date for hydrogen production-- producing 45 million hydrogen molecules per second.

PNNL is leading a new, approximately $6 million project to develop a new streamlined process to quickly pare down heaps of algae species into just a few that hold the most promise for making biofuel.

Super typhoons grow more intense when their fresh rains reduce the ocean below's salinity.

Intriguing images that reveal innovative scientific research will be on display in Olympia and Seattle through early April.

Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope.

New approach to monitoring sequestered carbon dioxide movement to be presented at AGU.

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.
