Materials scientists play atomic 'Jenga' and make a surprising discovery
Researchers got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra 'switch' that brings functionalities to materials when 'flipped' by external stimuli. The material defects induced polar behavior and can provide a new mechanism for manipulating electricity and magnetism in energy and information technologies.

Junior researchers showing world the way to advanced nuclear fuel design
Two early-career Idaho National Laboratory researchers are earning international attention for their groundbreaking work. They're getting a long-sought look into the 3-D microstructure of irradiated nuclear fuel, then feeding that data into cutting-edge fuel behavior models. Their work will make the design and testing of even safer nuclear fuels more informed and efficient.

Berkeley Lab's SPOT Suite transforms beamline science
For decades, synchrotron light sources have been operating on a manual grab-and-go data management model, but a recent deluge of data is quickly making this practice implausible. So Berkeley Lab X-ray scientists, facility users, computer and computational scientists, teamed up to create new tools for reducing, managing, analyzing and visualizing beamline data.The result of this collaboration is SPOT Suite, and it is already transforming the way scientists run their experiments at the ALS.

Sandia ensures US nuclear weapons deterrent can remain effective, credible
As part of its mission of ensuring the nation's stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they're hit by radiation, especially a type called fast neutrons. It created a science-based program called QASPR, which combines computer modeling and simulation, and experiments and technology development.

High-performance computing at Los Alamos announces milestone for key/value middleware
At Los Alamos, a supercomputer epicenter where 'big data set' really means something, a data middleware project has achieved a milestone for specialized information organization and storage. The Multi-dimensional Hashed Indexed Middleware project at Los Alamos National Laboratory recently achieved 1,782,105,749 key/value inserts per second into a globally-ordered key space on Los Alamos National Laboratory's Moonlight supercomputer.

Get ready for the computers of the future
Sandia experts expect multiple computing device-level technologies in the future, rather than one dominant architecture. About a dozen possible next-generation candidates exist, including tunnel FETs (field effect transistors, in which the output current is controlled by a variable electric field), carbon nanotubes, superconductors and fundamentally new approaches, such as quantum computing and brain-inspired computing.

Multidimensional image processing and analysis in R
An esoteric, open-source programming language -- called R -- could pave the way for open science. Thousands of scientists are participating in the R development community, including Berkeley Lab Postdoc Talita Perciano. As a student, she contributed one of the first image-processing tools -- called R Image Processing Analysis -- to the community. Now with big science datasets in mind, she's updated the existing tool with improved features for complex data analysis.

The brain: Key to a better computer
Although brain-inspired computing is in its infancy, Sandia National Laboratories has included it in a long-term research project whose goal is future computer systems. Neuro-inspired computing seeks to develop algorithms that would run on computers that function more like a brain than a conventional computer.

What lies beneath
The effects of biogeochemical and geochemical processes in the ground under us are on massive scales. Understanding what's going on down there and how it effects what's going on up here is an enormous undertaking. Scientists working at EMSL are getting a handle on these gigantic macroscopic processes by focusing on the microscopic scale. By creating micromodels and incorporating supercomputer simulations, researchers are connecting the molecular level with processes that affect our entire ecosystem.

Human-induced climate change reduces chance of flooding in Okavango Delta
Researchers at the University of Cape Town, Lawrence Berkeley National Laboratory and the United Nations Development Programme have analyzed how human-induced climate change has affected recent flooding in an ecologically and geographically unique river basin in southern Africa -- the Okavango River. After running a number of simulations, they found that greenhouse gas emissions have substantially reduced the chance of the floods in the region.

Tapping into the metabolome
Metabolomics -- a field often called "the last 'omics frontier" -- seeks to understand the fundamental metabolic workings of a cell in a changing environment. Scientists at EMSL use mass spectrometers, nuclear magnetic resonance, imaging devices and other cutting-edge instruments to glean the information to help produce better fuels, crops and other bioproducts.

Deployments of network monitoring software perfSONAR hit 1,000
Finding the network bottlenecks that can slow the flow of science data sets and impede research can be extremely complex, especially as such data transfers cross a multitude of linked networks. But perfSONAR, a network monitoring software package developed jointly by DOE's Energy Sciences Network, national labs, universities and Internet 2, is making that task much easier. In January 2014, the number of perfSONAR instances installed in the US and 13 other countries reached 1,000.
