Genetics and birthplace have a big effect on the make-up of the microbial community in the gut, according to new research published in the journal Nature Microbiology.

Six PNNL researchers named to the list of the most highly cited in the world. The list features scientists from around the world whose citations rank in the top one percent within 22 subject areas.

PNNL tools that track underground contaminants and speed carbon capture technology development are among R&D Magazine's 100 most innovative scientific breakthroughs of the year.

In fast-neutron reactors, fuel is sealed in ~7 millimeter diameter steel tubes called cladding. When a high-energy "fast" neutron strikes an atom in the steel, it can knock the atom out of place, like a cue ball striking another billiard ball. This leaves two types of damage in the metal: an empty spot where the atom was, and the displaced atom wedged between other atoms. Over time, these defects typically drive undesirable rearrangement of the microstructure, potentially reducing the life of the cladding.

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.

PNNL takes pride in advancing scientific frontiers and developing solutions to vexing problems. In particular, we apply our technical expertise to address national needs in security, energy and the environment.

As a Department of Energy national laboratory, you would expect Pacific Northwest National Laboratory to perform research in chemistry, physics and engineering in support of our energy, environmental and security missions.

Software that can reason like an analyst and a new way of disinfecting rooms won awards from the Federal Laboratory Consortium.

Scientists have made a "vitamin mimic" - a molecule that looks and acts just like a natural vitamin to bacteria - that offers a new window into the inner workings of living microbes.

Scientists have shown that a process known as oxidative stress is at work during the rendezvous between certain nanoparticles and immune cells known as macrophages.

Calcium carbonate found in chalk, shells and rocks is one of the most important materials on earth. New insights on how it turns into hard, strong materials will help scientists design materials needed for a low-carbon future.

Nuisance alarm rates in radiation detectors at seaports and ports of entry are down significantly due to PNNL data analysis efforts that are saving time and money at the ports.
