Nature Supercomputing, experiment combine for first look at magnetism of real nanoparticle
A multi-institution team simulated, for the first time, atomic-level magnetic properties in regions of a real nanoparticle based on experimental data. UCLA and Berkeley Lab's cutting-edge imaging and 3-D reconstruction techniques combined with the 27-petaflop Titan supercomputer at OLCF and the award-winning LSMS magnetic structure code, developed at ORNL, enabled researchers to model the magnetic properties of over a thousand atoms of an iron-platinum nanoparticle -- a material that has applications for next-generation magnetic storage devices.

Proceedings of the National Academy of Sciences Neutrons identify critical details in bacterial enzyme implicated in gastric cancer
Neutron analysis at the Department of Energy's Oak Ridge National Laboratory is helping researchers better understand a key enzyme found in a bacterium known to cause stomach cancer. Understanding the details of this enzyme, and thus the Helicobacter pylori bacteria's metabolism and biological pathways, could be central to developing drugs that act against H. pylori, but that do not attack the stomach's useful bacteria.
