Rising river waters deliver a feast of carbon to hungry microbes where water meets land, triggering increased activity and altering the flow of greenhouse gases into the atmosphere.

PNNL researchers are designing synthetic polymers with the versatility of nature's original polymers, the ubiquitous proteins.

For the first time, researchers have been able to see what makes this titanium alloy so strong – and then make it stronger.

Discovery in action. These words describe what we do at PNNL. For more than 50 years, we have advanced the frontiers of science and engineering in the service of our nation and the the world.
