19-May-2017 A fresh math perspective opens new possibilities for computational chemistry
A new mathematical "shortcut" developed by Berkeley Lab researchers is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours. These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year.
21-Mar-2017 Berkeley Lab researchers make NWChem's Planewave 'purr' on Intel's KNL architectures
Berkeley Lab researchers have successfully added thread-level parallelism on top of MPI-level parallelism in the planewave density functional theory method within the popular software suite NWChem. An important step to ensuring that computational chemists are prepared to compute efficiently on next-generation exascale machines.
28-Feb-2017 The heat is on
NASA is developing a new family of flexible heat-shield systems with a woven carbon-fiber base material, and is using X-rays at Berkeley Lab's Advanced Light Source to test the designs.
21-Feb-2017 When rocket science meets X-ray science
NASA and Berkeley Lab researchers have teamed up to explore next-generation spacecraft materials at the microscale using an X-ray technique that produces 3-D images. This work could help ensure future spacecraft survive the rigors of otherworldly atmospheres.
1-Feb-2017 Simulations reveal the invisible chaos of superluminous supernovae
To better understand the physical conditions that create superluminious supernova, astrophysicists are running 2-D simulations of these events using supercomputers at the Department of Energy's National Energy Research Scientific Computing Center and the Lawrence Berkeley National Laboratory (Berkeley Lab) developed CASTRO code.
27-Jan-2017 Art Rosenfeld, California's godfather of energy efficiency, dies at 90
Art Rosenfeld, a Lawrence Berkeley National Laboratory Distinguished Scientist Emeritus who is also known as California's 'godfather' of energy efficiency and who has been credited with being personally responsible for billions of dollars in energy savings, died Friday at his home in Berkeley, California. He was 90.
21-Dec-2016 Filling in the nuclear data gaps
Berkeley Lab's Nuclear Data Group is conducting new experiments to address common data needs in nuclear medicine, nuclear energy and fusion R&D, security, and counterproliferation work.
19-Oct-2016 Underground science: Berkeley Lab digs deep for clean energy solutions
About a mile beneath the Earth's surface in an old gold mine, Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have built an observatory to study how rocks fracture. The knowledge they gain could ultimately help reduce greenhouse gas emissions and accelerate deployment of clean energy technologies.
12-Oct-2016 Planetarium show brings 'phantom' matter to life
A new planetarium show is designed to immerse audiences in the search for dark matter, which we have so far detected only through its gravitational effects though it makes up most of the mass of the universe.
19-May-2016 Berkeley Lab's OpenMSI licensed to ImaBiotech
Two years ago, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers developed OpenMSI--the most advanced computational tool for analyzing and visualizing mass spectrometry imaging (MSI) data. Last year, this web-available tool was selected as one of the 100 most technologically significant new products of the year by R&D Magazine. Now, OpenMSI has been licensed to support ImaBiotech's Multimaging™ technology in the field of pharmaceutical and cosmetic research and development.
2-May-2016 Could aluminum nitride be engineered to produce quantum bits?
The leading method for creating quantum bits, or qubits, currently involves exploiting the structural defects in diamonds. But using NERSC resources, University of Chicago researchers found that the same defect could be engineered in cheaper aluminum nitride. If confirmed by experiments, this could significantly reduce the cost of manufacturing quantum technologies.
22-Feb-2016 Updated workflows for new LHC era
After a massive upgrade, the Large Hadron Collider (LHC) is smashing particles at an unprecedented 13 teraelectronvolts (TeV) -- nearly double the energy of its previous run. In just one second, the LHC can now produce up to 1 billion collisions and generate up to 10 gigabytes of data.
To deal with the new data deluge, researchers working on the LHC's ATLAS experiment are relying on updated workflow management tools developed primarily by Berkeley Lab researchers.
21-Jan-2016 Explore galaxies far, far away at internet speeds
Scientists have released an 'expansion pack' for a virtual tour of the universe that you can enjoy from the comfort of your own computer. The latest version of the publicly accessible images of the sky, which can be viewed using an interactive Sky Viewer tool, roughly doubles the size of the searchable universe from the project's original release in May.
4-Sep-2015 Fortifying computer chips for space travel
One of the most long-lived and active space-chip testing programs is at the Berkeley Lab. Since 1979, most American satellites and many major NASA projects including the Mars Rover Curiosity, the space shuttles, and the new Orion capsule, have had one or more electronic components go through Berkeley Lab's cyclotron.
1-Sep-2015 Time-lapse analysis offers new look at how cells repair DNA damage
Time-lapse imaging can make complicated processes easier to grasp. Berkeley Lab scientists are using a similar approach to study how cells repair DNA damage. Microscopy images are acquired about every thirty minutes over a span of up to two days, and the resulting sequence of images shows ever-changing hotspots inside cells where DNA is under repair.
24-Jun-2015 Berkeley Lab scientists to develop better way to screen chemicals for cancer-causing effects
Berkeley Lab scientists are developing a cell culture that could help researchers better identify chemicals that increase breast cancer susceptibility. The scientists will grow the culture using adult stem cells obtained from breast tissue. Their test will show if a chemical causes a breakdown in cell-to-cell communication, a fundamental defect of cancer.
15-Jun-2015 What the blank makes quantum dots blink?
Quantum dots promise an astounding range of applications, if scientists can conquer their annoying habit of blinking. Researchers computing at NERSC recently ran simulations that offer new insights into the problem.
1-Jun-2015 Meraculous: Deciphering the 'book of life' with supercomputers
A team of scientists from Berkeley Lab, JGI and UC Berkeley, simplified and sped up genome assembly, reducing a months-long process to mere minutes. This was primarily achieved by 'parallelizing' the code to harness the processing power of supercomputers, such as NERSC's Edison system.
11-May-2015 'Chombo-crunch' sinks its teeth into fluid dynamics
Researchers at Lawrence Berkeley National Laboratory are breaking new ground in the modeling of complex flows in energy and oil and gas applications, thanks to a computational fluid dynamics and transport code dubbed 'Chombo-Crunch.'
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
