26-Oct-2015 The silent treatment: EMSL's quiet wing
Scientists are advancing the understanding of biological and environmental systems by conducting at least part of their research in EMSL's Quiet Wing, one of the most advanced quiet laboratories in the world for high-resolution imaging capabilities. Scientists are using this facility for a wide range of research areas, including: to study bacteria in complex soil aggregates, to understand the behavior of a unique multicopper oxidase and to explore remediation methods using porous clay.
15-Oct-2015 W80-4: Sandia California works on nuclear weapon Life Extension Program
Sandia National Laboratories is performing a Life Extension Program on the W80-4 nuclear weapon. The Life Extension Program is refurbishing the W80 warhead with replacement components for aging technology and components that have limited lifespans. Much of the work is being done at Sandia's California site.
29-Jun-2015 Magnetic attraction
Researchers studying a broad spectrum of science, including biofuel production processes, climate effects on carbon cycling in the soil and carbon transformations in the atmosphere will soon have access to EMSL's new 21 Tesla Fourier transform ion cyclotron resonance mass spectrometer. Scientists are eager to start getting molecular-level information for their research, and six inaugural studies were selected to use the new instrument through a Special Science Call.
29-Apr-2015 Special science call projects announced
EMSL's Special Science Call for Proposals ran from mid-April through September and generated 23 accepted studies. The call challenged prospective users to submit high-impact research projects that took advantage of EMSL's technical resources including RadEMSL, the Quiet Wing microscopy and NanoSIMS capabilities, and HRMAC. The research associated with the call is progressing, and the projects will soon start delivering important scientific findings.
28-Apr-2015 Ground control
The United Nations General Assembly declared 2015 the International Year of Soils. Soil is critical for food production and climate regulation. It's a complex underground ecosystem of organisms that process decaying debris to enrich the land as well as store and release carbon into the atmosphere. However, human activity and changing climate are impacting this environmental system. Scientists working at EMSL are trying to understand the complexities of soil to develop better sustainable land management to protect it.
7-Jan-2015 'Seeing' hydrogen atoms to unveil enzyme catalysis
A multi-institutional research team led by Chris Dealwis from Case Western Reserve University has used the new IMAGINE instrument at Oak Ridge National Laboratory's High Flux Isotope Reactor to map an enzyme that could play an important role in anti-cancer drug development.
22-Jul-2014 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.
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.
15-Apr-2014 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.
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.
