Future holiday homecomings could include efficient heat pumps in cold climates and homes designed and built with the environment in mind.

Scientists are studying tiny subatomic particles that pass through humans and possess clues about the origins of the universe.

Researchers developed two solutions for air-conditioning—a novel, energy-efficient dehumidification system and a technology to detect refrigerant leaks. Both help increase energy-efficiency and reduce costs.

Researchers at the Department of Energy's Pacific Northwest National Laboratory are helping to lead transformation of the nation's century-old electric grid by developing new technologies to enhance its reliability and security.

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