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.

The search for dark matter called spin-dependent WIMPS is on — in an underground lab in Canada

PNNL is helping to create open-access power grid datasets for use in testing new grid technologies.

PNNL researchers get new opportunities to shape the country’s power grid for the future.

Here at the Department of Energy's Pacific Northwest National Laboratory, much of our physics research focuses on fundamental scientific discovery and national security.
