In a 3D structure of the protein, the binding site is shown in pink, representing a potential drug target. The green molecule shows binding of an antibiotic to the protein. Click to enlarge. Image courtesy of Wladek Minor.
Newly ID’d protein provides target for antibiotic-resistant hospital bacterium

Researchers have made inroads into tackling a bacterium that plagues hospitals and is highly resistant to most antibiotics. They determined the 3-D structure and likely function of a new protein in this common bacterium that attacks those with compromised immune systems

The release of wastes associated with nuclear reprocessing from storage facilities into the underlying sediments and groundwater is an important environmental concern. Scientists working with two national laboratories have found evidence that iron-bearing minerals naturally abundant in some sediments can react with and immobilize contaminants such as technetium.

Iron-bearing minerals in sediments naturally reduce contaminant levels

The release of wastes associated with nuclear reprocessing from storage facilities into the underlying sediments and groundwater is an important environmental concern. Scientists working with two national laboratories have found evidence that iron-bearing minerals naturally abundant in some sediments can react with and immobilize contaminants such as technetium.
