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.
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.
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.
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.
