Emissions of isoprene, a compound from plant matter that wields great influence in the atmosphere, are up to three times higher in the Amazon rainforest than scientists have thought.

The May 18, 1980, eruption of Mount St. Helens clouded the Pacific Northwest prompted a trove of research for some PNNL scientists.

Clouds in the eastern North Atlantic region will come under scrutiny from a bevy of airplane-based instruments this summer as scientists analyze the physical and chemical properties of clouds and aerosols.

Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study in Nature Communications.

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.

Small particles of pollution and dust make clouds brighter, and now scientists have figured out a way to better use data to improve our understanding of how this process affects the planet's climate.

High concentrations of tiny pollution particles can invigorate cloud formation and boost snowfall on mountains, according to a new study.

A new window on the Arctic region is opening up, thanks to a new unmanned aerial system that has taken to the skies.

Rick Corley has been honored for his work modeling the full chain of human respiration, from organ, to tissue, to cell, and down to individual molecule.

The rate of plant photosynthesis globally has blossomed this century, according to a new study in the journal Nature by a scientist at the Joint Global Change Research Institute and his colleagues.

A study of mountaintop clouds over Colorado has delivered crucial information to help answer several scientific questions, including how Saharan dust affects clouds over North America.

Greater WSU grad student presence at PNNL

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

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

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.

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.
