There are hundreds of billions of stars in our own Milky Way galaxy, interspersed with all manner of matter, from the dark to the sublime. This is the universe that Argonne researcher Salman Habib is trying to reconstruct, structure by structure, combining telescope surveys with next-generation data analysis and simulation techniques currently being primed for exascale computing.
Using X-ray techniques, scientists are developing an analysis tool that can more accurately predict how sulfur compounds in a batch of crude oil might corrode equipment- an important safety issue for the oil industry.
A team of researchers in the US and Europe are part of the Real-Time Super Lab concept to study how electricity can be rerouted across vast distances to address disruptions. The team envisions that large-scale blackouts can be prevented by moving electricity intercontinentally, the same way utilities currently do regionally but at a much larger scale. Such global interaction can reduce the cost of outages and make electrical power grids of the future more resilient.
In a recent experiment conducted at the Department of Energy's SLAC National Accelerator Laboratory, a research team used bright, ultrafast X-ray pulses from SLAC's X-ray free-electron laser to create a high-speed movie of a fluorescent protein in action. With that information, the scientists began to design a marker that switches more easily, a quality that can improve resolution during biological imaging.
The Northwestern Institute of Science and Engineering this summer offered its inaugural summer research program for 12 undergraduate science and engineering majors. During the 10-week program, the students worked on projects of mutual strategic importance to Argonne and the university in machine learning, environmental sensing, synthetic biology, materials synthesis and characterization, and energy storage.
19-Sep-2017 A TOAST for Next Generation CMB Experiments
Computational cosmologists at Berkeley Lab they recently achieved a critical milestone in preparation for upcoming CMB experiments: scaling their data simulation and reduction framework TOAST to run on all 658,784 Intel Knights Landing Xeon Phi processor cores on the NERSC's Cori. The team also implemented a new module to simulate the noise introduced when ground-based telescopes look at the CMB through the atmosphere.
Joe Nichols, of the University of Minnesota, is using ALCF resources to create high fidelity simulations of jet turbulence to determine how and where noise is produced. The results may lead to novel engineering designs that reduce noise over commercial flight paths and on aircraft carrier decks.
Using a multi-lab approach, Argonne researchers are tapping the laboratory's vast arsenal of innovative technologies to map the intricacies of brain function at the deepest levels, and describing them in greater detail than ever before through advanced data analysis techniques. The brain connectome project is supported by the Argonne Leadership Computing Facility's new Data Science Program, a new initiative targeted at big data problems.
11-Sep-2017 Hewlett Packard's Suhas Kumar wins 2017 Klein Award
Suhas Kumar, a postdoctoral researcher at Hewlett Packard Enterprise (HPE), wants to develop next-generation information storage devices and better computers. His particular interest is a new type of electronic device, called a memristor, that could make future computer memories faster, more durable and more energy efficient than today's flash memory. Now, his work has been recognized with the 2017 Melvin P. Klein Scientific Development Award of the Stanford Synchrotron Radiation Lightsource (SSRL) at the Department of Energy's SLAC National Accelerator Laboratory.
The two-day 'CodeGirls at Argonne' camp seeks to immerse the girls in computer science before they enter high school. The camp helps break down the typical stereotype of coding being a solitary and male activity. At Argonne, computer scientists work as part of interdisciplinary teams that focus on solving problems.
7-Sep-2017 Students Discuss 'Cosmic Opportunities' at 45th Annual SLAC Summer Institute
When the moon threw its shadow on the Department of Energy's SLAC National Accelerator Laboratory during the Aug. 21 partial solar eclipse, it created the perfect backdrop for the 45th annual SLAC Summer Institute (SSI). This year, the program was all about the fascinating universe. The two-week summer institute attracted an international crowd of 123 participants, mostly graduate students and postdoctoral researchers, who discussed 'cosmic opportunities' in particle physics and astrophysics research with world-renowned experts in the field.
5-Sep-2017 Olympics of the mind
The Argonne Afro-Academic, Cultural, Technological and Scientific Olympics (ACT-SO) High School Research Program, is a mentorship program supported by the US Department of Energy's Argonne National Laboratory. Argonne's volunteer mentors work closely with African-American students to help them compete in the national ACT-SO competition, hone their research skills and even help to boost their confidence to strive for more.
Graphene's remarkable electronic properties have surprised scientists for years. But electrons move through it too easily to use it in everyday electronics. Scientists are researching a variety of ways to direct its electron traffic: creating nanoribbons of it, stretching it, using it with boron nitride, and even making 'artificial atoms' in it.
Berkeley Lab researchers have developed a new method of analyzing the molecular-scale structure of organo-lead halide perovskites, a promising class of materials that could energize the solar cell industry. They combined advanced X-ray spectroscopy measurements with calculations based on fundamental, 'first principles' theory to obtain an atomic-scale view of the material.
A new way of operating the powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory has enabled researchers to detect and measure fluctuations in magnetic structures being considered for new data storage and computing technologies.
The American Physical Society has recognized Blair Ratcliff, an emeritus physicist at SLAC and Stanford University, with the 2017 Division of Particles and Fields Instrumentation Award 'for the development of novel detectors exploiting Cherenkov radiation' -- an advance that greatly enhanced BABAR's capabilities and influenced the design of other experiments.
In a new approach to enable scientific breakthroughs, researchers linked together supercomputers at the Argonne Leadership Computing Facility (ALCF) and at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.
In July, the US Department of Energy's (DOE) Argonne National Laboratory hosted a five-day Coding Camp for more than two dozen high school juniors and seniors, teaching new programming skills and how computer science is an integral part of an Argonne researcher's life.
An experiment called ALICE at the Large Hadron Collider is dedicated to the study of heavy-ion collisions. ALICE stands for 'A Large Ion Collider Experiment.' Its aim is spotting the high-energy, elementary particles, like electrons and gamma rays, streaming from the quark-gluon plasma, to explore the physics of the early universe. Oak Ridge National Laboratory physicist Thomas M. Cormier provides an update on the experiment.
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.
