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.

Scientists pinpoint creeping nanocrystals behind lithium-ion battery degradation
Scientists from several US Department of Energy national laboratories -- Lawrence Berkeley, Brookhaven, SLAC, and the National Renewable Energy Laboratory -- mapped the nanoscale dynamics of lithium-ion charge cycles and discovered never-before-seen evolution and degradation patterns in two key battery materials.

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.

Industry research: Experiment enters next stage at new Idaho hot cell
To the average eye, the experimental specimens don't look like much: silver-colored squares about the size of a domino. But the samples represent several big milestones for Idaho National Laboratory, the Department of Energy and the US nuclear energy industry. The irradiated 'compact tension' specimens are the first to undergo analysis in a specialized test rig at INL. Plus, they're part of a first-of-its-kind collaboration through the DOE's Advanced Test Reactor National Scientific User Facility.

Scientists to map universe in 3-D HD
In a few years, scientists will come out with a new map of a third of the sky, one that will go deeper and bring that depth into sharper focus than any survey has yet achieved. It will pinpoint in three dimensions the locations of 25 million galaxies and quasars, pulling back the curtains on the history of the universe's expansion over more than half of the age of the universe.

Engineering better machines and buildings by understanding mechanics of materials
Sandia National Laboratories is working to fill gaps in the fundamental understanding of materials science through an ambitious long-term, multidisciplinary project called Predicting Performance Margins, or PPM. From the atomic level to full-scale components, the research links variability in materials' atomic configurations and microstructures with how actual parts perform.

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.

Label-free, sequence-specific, inexpensive fluorescent DNA sensors
Using principles of energy transfer more commonly applied to designing solar cells, scientists at the US Department of Energy's Brookhaven National Laboratory have developed a new highly sensitive way to detect specific sequences of DNA, the genetic material unique to every living thing. As described in a paper published in the journal Chemistry of Materials, the method is considerably less costly than other DNA assays and has widespread potential for applications in forensics, medical diagnostics, and the detection of bioterror agents.

Is the universe balanced on a pinhead?
Scientists have known the mass of the heaviest fundamental particle, the top quark, since 1995. But recent, more precise measurements of this mass have revived an old question: Why is it so huge? No one is sure, but it might be a sign that our universe is inherently unstable. Or it might be a sign that some factor we don't yet understand is keeping us in balance.

Wind tunnel tests support improved aerodynamic design of B61-12 bomb
Sandia National Laboratories has finished eight days of testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel. The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system, the B61-12.

Simulation solves mystery of how liquid-crystal thin films disintegrate
Approximately four decades ago, theoreticians believed that only one of two mechanisms could explain rupture of liquid-crystal thin films. They also believed that these two mechanisms could not coexist. But 10 years ago experiments showed that these two mechanisms in many cases do coexist, according to Trung Nguyen of Oak Ridge National Laboratory, who ran unprecedented large-scale molecular dynamics simulations on Titan, America's fastest supercomputer, to model the beginnings of ruptures in thin films.

Oak Ridge National Laboratory researchers contribute to prestigious climate report
Thomas Wilbanks and Benjamin Preston, both of the Climate Change Science Institute at Oak Ridge National Laboratory, are among the 309 coordinating lead authors of the Intergovernmental Panel on Climate Change's Working Group II report. The report, which was released in Japan on March 31, found that climate change isn't just a problem for future generations, but also impacts humans in the present day.

Tracking the transition of early-universe quark soup to matter-as-we-know-it
By smashing together ordinary atomic nuclei at the Relativistic Heavy Ion Collider, scientists recreate the primordial soup of the early universe thousands of times per second. Using sophisticated detectors to track what happens as exotic particles emerge from the collision zone and 'freeze out' into more familiar forms of matter, they are turning up interesting details about how the transition takes place.

Nanoparticles assembled in new ways hold the promise of a wave of new high-tech materials that could offer high strength, enhanced magnetic properties, light reflectivity or absorption, use as catalysts and much more. Scientists at the US Department of Energy's Ames Laboratory have developed a theoretical model to explore the effect of polymer coatings, including DNA, for self-assembly of nanocubes into so-called superlattices.

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.
