18-Aug-2014 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.

29-May-2014 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.
29-May-2014 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.
15-May-2014 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.
6-May-2014 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.
21-Apr-2014 Computer-assisted accelerator design
Accelerator physicist Stephen Brooks uses custom designed software to create a 3-D virtual model of the electron accelerator Brookhaven physicists hope to build inside the tunnel currently housing the Relativistic Heavy Ion Collider.
7-Apr-2014 Generations of supercomputers pin down primordial plasma
Brookhaven Lab's Lattice Gauge Theory Group hunts for equations to describe the early universe and the forces binding matter together. Their search spans generations of supercomputers and parallels studies of the primordial plasma discovered and explored at Brookhaven's Relativistic Heavy Ion Collider.
27-Mar-2014 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.
18-Mar-2014 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.
17-Mar-2014 A new mathematics for experimental science
In the age of high-resolution detectors and international research collaborations, math has the potential to transform science and accelerate discovery. But this work will require state-of-the-art mathematics, carefully crafted in inventive new ways. That's where the Center for Applied Mathematics for Energy Research Applications (CAMERA) at Lawrence Berkeley National Laboratory comes in.
30-Jan-2014 Early Edison users deliver results
Before any supercomputer is accepted at NERSC, scientists are invited to put the system through its paces during an "early science" phase. While the main aim of this period is to test the new system, many scientists are able to use the time to significantly advance their work.

Researchers supported by the Department of Energy's Office of Science have made an incredibly precise map of the universe to better understand dark energy and other wonders within.
27-Jan-2014 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.
