On World Oceans Day, an international team of marine scientists reports that the potential impact of marine renewable energy to marine life is likely small or undetectable, though some uncertainty remains.
The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, according to a new study in the journal Nature.
Two PNNL scientists who study the earth system have been selected to receive 2018 Early Career Research Program awards from the U.S. Department of Energy.
For the first time, researchers have created a gram of yellowcake — a powdered form of uranium used to produce fuel for nuclear power production — using modified acrylic fibers to extract it from seawater.
A rocket will thunder off from a NASA launch pad this weekend, carrying a handful of seeds that are part of a science experiment in which PNNL plays a key role.
A mix of factors is contributing to an increasing mortality rate of trees in the moist tropics, where trees are dying at about twice the rate they were 35 years ago.
Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a study by PNNL scientists and colleagues in the journal Science.
A new research approach to geoengineering could potentially be used to limit Earth's warming to a specific target while reducing some of the risks and concerns identified in past studies.
PNNL scientist Janet Jansson led scores of scientists who published in the journal Nature the most extensive snapshot ever of the vast microbial life on Earth.
