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.
To study some of the tiniest particles in the universe, an international band of physicists is building a massive instrument to look for signs of particles predicted to be fundamental to the workings of the universe.
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 is supporting today's announcement by the White House about efforts related to soil sustainability by sponsoring research projects through two research initiatives.
