18-Jun-2015 Adapting nanoscience imaging tools to study ants' heat-deflecting adaptations
A new study shows that the tiny hairs of Saharan silver ants possess crucial adaptive features that allow the ants to regulate their body temperatures and survive the scorching hot conditions of their desert habitat. To study how the hairs allow the creatures to control electromagnetic waves in this manner, the Columbia Engineering research team turned to the resources and expertise available at Brookhaven Lab's Center for Functional Nanomaterials.
13-Apr-2015 Long-sought magnetic mechanism observed in exotic hybrid materials
Scientists have measured the subatomic intricacies of an exotic phenomenon first predicted more than 60 years ago. This so-called van Vleck magnetism is the key to harnessing the quantum quirks of topological insulators -- hybrid materials that are both conducting and insulating -- and could lead to unprecedented electronics.
10-Apr-2015 Bacteria tracked feeding nitrogen to nutrient-starved plants
An international team of researchers, including three from Brookhaven National Laboratory, tracked nitrogen as soil bacteria pulled it from the air and released it as plant-friendly ammonium. This eco-friendly process -- called biological nitrogen fixation -- substantially promoted growth in certain grass crops.
25-Mar-2015 A tale of 2 colliders, 1 thesis, 2 awards -- and a physics mystery
Dennis Perepelitsa, a physicist exploring the mysteries of nuclear physics at RHIC and the LHC, has the distinction of being the first person to earn outstanding Ph.D. thesis awards from both research communities. His Ph.D. work, based on complementary data collected at the PHENIX and ATLAS detectors, showcased intriguing findings and an ongoing mystery that is guiding part of the research programs at both machines now.
18-Mar-2015 Nanostructure complex materials modeling
Brookhaven physicist Simon Billinge illustrates how advances in computing and applied mathematics can improve the predictive value of models used to design new materials.
17-Mar-2015 Granular data processing on HPCs using an event service
Brookhaven Lab/ATLAS physicist Torre Wenaus describes an effort to trickle small 'grains' of data generated by the ATLAS experiment at the Large Hadron Collider (LHC) in Europe into small pockets of unused supercomputing time, sandwiched between big jobs on high-performance supercomputers.
6-Feb-2015 Energy Secretary Moniz dedicates the world's brightest Synchrotron Light Source
US Department of Energy (DOE) Secretary Ernest Moniz today dedicated the world's most advanced light source, the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory (BNL). The NSLS-II is a $912-million DOE Office of Science User Facility that produces extremely bright beams of x-ray, ultraviolet, and infrared light used to examine a wide range of materials, including superconductors and catalysts, geological samples, and biological proteins to accelerate advances in energy, environmental science, and medicine.
15-Jan-2015 RHIC physics feeds future high-tech workforce: Ágnes Mócsy
Ágnes Mócsy, a theoretical physicist and tenured associate professor at Pratt Institute, one of the world's prestigious art and design universities, hopes to convey the sense of awe she experienced seeing Brookhaven Lab's particle collider to the art students she teaches in physics and astronomy classes for non-physics majors.
5-Jan-2015 2014's top-10 scientific achievements at Brookhaven Lab
From new insights into the building blocks of matter to advances in understanding batteries, superconductors, and a protein that could help fight cancer, 2014 was a year of stunning successes for the US Department of Energy's Brookhaven National Laboratory.
22-Oct-2014 Brookhaven Lab launches Computational Science Initiative
NY-Building on its capabilities in computational science and data management, the US Department of Energy's Brookhaven National Laboratory is embarking upon a major new Computational Science Initiative. This program will leverage computational science expertise and investments across multiple programs at the Laboratory-including the flagship facilities that attract thousands of scientific users each year-further establishing Brookhaven as a leader in tackling the 'big data' challenges at the frontiers of scientific discovery.
1-Oct-2014 Brookhaven and the Daya Bay Neutrino Experiment
The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a particle that could have a profound impact on our understanding of the universe. US Daya Bay Chief Scientist Steve Kettell of Brookhaven National Laboratory offers commentary on the implications of this research.
15-Jul-2014 Physicists detect process even rarer than the long-sought Higgs particle
Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world's largest and most powerful 'atom smasher,' report the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles.
29-May-2014 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.
29-Apr-2014 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.
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.
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.
