Differences in spatial correlation coefficients between a high resolution regional scale simulation and observations (top) as well as between a coarse resolution global scale simulation and observations (bottom). Cross hatching indicates that the differences are statistically significant. Image courtesy Jiali Wang; click to view larger.
New methods for identifying value added by a regional climate model

In a paper published in the Journal of Geophysical Research – Atmospheres, researchers identified the value added by a regional climate model - which addresses a long-standing question in the scientific community on the utility of downscaling.

Figure 1: Aquatic and terrestrial environments are dynamic systems where coupled microbiological, geochemical, and hydrological processes define the complex interactions that drive the biogeochemical cycling of the major and minor elements. For example, microbial iron and sulfate reduction profoundly affect the biogeochemical cycling of carbon, iron, and sulfur in natural systems; however, the dynamics of microbial iron and sulfate reduction in the presence of both iron(III) oxides (i.e., “rust”) and sulfate (forms of iron and sulfur commonly found in nature) are not well-understood in systems with mixed microbial populations.

Figure 1: NDM-1 in complex with hydrolyzed ampicillin. Stereoview of the active site, with carbon atoms in the protein shown in cyan; those in the substrate are pink. Nitrogen atoms are blue, oxygen atoms are red, sulfur atoms are yellow, and zinc ions are magenta. An oriented water molecule (W) is gray. The Fo-Fc electron density around the substrate is contoured at 3σ. Dashed lines indicate key interactions between the protein and zinc ions. To view a larger version of the image, click on it.
Solving the catalytic pathway of antibiotic resistance
