SLAC theoretical physicist and Stanford Professor Emeritus James D. 'BJ' Bjorken has been awarded the 2015 Wolf Prize in Physics for his key role in elucidating the nature of the strong force and predicting what would happen if electrons were violently slammed into protons in the atomic nucleus.
11-Feb-2015 Smashing polarized protons to uncover spin and other secrets
If you want to unravel the secrets of proton spin, put a 'twist' in your colliding proton beams. The Relativistic Heavy Ion Collider is the only facility in the world with the ability to collide such spin-polarized protons. The latest round of these collisions has just begun and will continue for approximately the next nine weeks.
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.
2-Feb-2015 Five ways to put tiny targets in front of an X-ray laser
X-ray devices have long been used to see the inner structure of things, from bone breaks in the human body to the contents of luggage at airport security checkpoints. But to see life's chemistry and exotic materials at the scale of individual atoms, you need a far more powerful X-ray device. Enter the Linac Coherent Light Source X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory.
27-Jan-2015 SLAC welcomes professor and Chemical Sciences Division director Tony Heinz
Tony Heinz, a scientist known for exploring the properties of nanoscale materials and developing important new tools for that exploration, has joined the Department of Energy's SLAC National Accelerator Laboratory as a professor of photon science and Stanford University as a professor of applied physics. He will also lead the SLAC Chemical Sciences Division.
20-Jan-2015 Pinpointing the magnetic moments of nuclear matter
Using supercomputing resources at the National Energy Research Scientific Computing Center at Berkeley Lab, a team of nuclear physicists has demonstrated for the first time the ability of quantum chromodynamics (QCD) -- a fundamental theory in particle physics -- to calculate the magnetic structure of some of the lightest nuclei. Their findings are part of an ongoing effort to further our understanding of the universe.
16-Jan-2015 SLAC's Peter Rowson named American Physical Society fellow
SLAC staff physicist Peter Rowson has been elected a fellow of the American Physical Society, the largest physics association in the world. APS confers this distinction on a small percentage of the society's membership; it is especially significant because it is a peer-nominated honor.

A team led by the Department of Energy's Oak Ridge National Laboratory has discovered a way to dramatically increase the selectivity and binding strength of crown ethers by incorporating them within a rigid framework of graphene. Strong, specific electrostatic binding of crown ethers may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.
15-Dec-2014 Is the Higgs Boson a piece of the matter-antimatter puzzle?
Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some -- but not all -- of the imbalance between matter and antimatter in the universe. Now a SLAC theorist and his colleagues have laid out a possible method for determining if the Higgs boson is involved.
4-Dec-2014 Rattled atoms mimic high-temperature superconductivity
An experiment at the Department of Energy's SLAC National Accelerator Laboratory provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity -- a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.
1-Dec-2014 Optimized algorithms boost combustion research
Turbulent combustion simulations, used in the design of more fuel-efficient combustion systems, have gotten their own efficiency boost, thanks to researchers from Berkeley Lab's Computational Research Division. They developed new algorithmic features that streamline turbulent flame simulations, which are commonly used in the design of combustion systems such as diesel engines; after testing the enhanced code on NERSC supercomputers, they were able to achieve dramatic improvements in simulation times, which will help reduce the time -- and thus the cost -- of designing new engines.
24-Nov-2014 Berkeley Lab algorithms help researchers understand dark energy
To unlock the mystery of dark energy and its influence on the universe, researchers must rely on indirect observations -- watching how fast Type Ia supernovae recede from us as the universe expands. The process of identifying and tracking these objects requires scientists to scrupulously monitor the night sky for slight changes, a task that would be tedious and time-consuming for the Dark Energy Survey without novel tools developed by Berkeley Lab and UC Berkeley researchers.
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.
