By combining computational modeling with experimental research, scientists identified a promising composition that reduces the need for a critical material in an alloy that can withstand extreme environments.

PNNL biodefense experts seek to identify, understand and mitigate the risks of biological pathogens—whether naturally occurring or intentionally created—so steps can be taken to prepare and respond.

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

Researchers delivering new solutions to speed development and deployment of advanced reactor concepts.

While some of us may periodically ponder the universe, most of us don't dedicate our lives to studying its mysteries, including its birth, evolution and fate.

Nuclear power figures prominently in our country's energy portfolio and is essential to our economic and environmental 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.
