Learning About Material Integrity from Statistical Data

Whether it protects space satellites or sequesters nuclear waste, scientists want to understand tiny features that could significantly alter how a material behaves. Locating microscopic defects can be done with powerful microscopes, but scientists want more. They want to use the microscopes to locate and understand the very molecules involved in the defects. Describing the location of the molecules and atoms in images often relies on statistics that can be inaccurate and expensive.

Modeling Microbes to Manage Carbon Dioxide

In the past decade, microbiologists began realizing that communities of microbes process energy and materials, which affects their environments. To understand how microbial communities function in a natural ecosystem, Pacific Northwest National Laboratory scientists developed a novel kinetic model that represents microbial community dynamics in soil pores.

Bacteria to the Rescue

At several U.S. Department of Energy (DOE) sites, uranium mining, milling, and processing have led to groundwater contamination that persists above drinking water standards—in spite of natural flushing and the removal of contaminated sediments. A multi-institutional research team, including researchers at DOE's Pacific Northwest National Laboratory (PNNL), is investigating the use of bioremediation to treat the subsurface uranium plumes and remove pollutants.
