Accelerator physicists at the U.S. Department of Energy's Brookhaven National Laboratory have successfully implemented an innovative scheme for increasing proton collision rates at the Relativistic Heavy Ion Collider (RHIC). More proton collisions at this DOE Office of Science User Facility produce more data for scientists to sift through to answer important nuclear physics questions, including the search for the source of proton spin.

Scientists have for the first time viewed how bacterial proteins self-assemble into thin sheets and begin to form the walls of the outer shell for nano-sized polyhedral compartments that function as specialized factories. The new insight may aid scientists who seek to tap this natural origami by designing novel compartments or using them as scaffolding for new types of nanoscale architectures, such as drug-delivery systems.
With the production of 50 grams of plutonium-238, researchers at the Department of Energy's Oak Ridge National Laboratory have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for NASA and other missions.
A new study conducted at Oak Ridge National Laboratory's Spallation Neutron Source (SNS), has revealed promising results that could drastically boost the performance of solid-state electrolytes, and could potentially lead to a safer, even more efficient battery. Researchers used neutron diffraction (the VULCAN instrument, SNS beam line 7) to conduct an in-depth study probing the entire structure evolution of doped garnet-type electrolytes during the synthesis process to unravel the mechanism that boosts the lithium-ionic conductivity.
Renewable energy can be stored for less with PNNL's new organic aqueous flow battery, which uses inexpensive and readily available materials. The new battery is expected to cost about 60 percent less than today's standard flow batteries.
An ultra-high-resolution technique used for the first time to study polymer fibers that trap uranium in seawater may cause researchers to rethink the best methods to harvest this potential fuel for nuclear reactors.
Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Now, for the first time, the interplay between the plasmon mode and the single particle excitation within a small metal cluster has been simulated directly. Researchers with Berkeley Lab used a real-time numerical algorithm to study both the plasmon and hot carrier within the same framework. That is critical for understanding how long a particle stays excited, and whether there is energy backflow from hot carrier to plasmon.
The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of South Dakota, has already proven itself to be the most sensitive dark matter detector in the world. Now scientists have significantly enhanced its ability to look for WIMPs, or weakly interacting massive particles, which are among the leading candidates for dark matter.
The Large Underground Xenon dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility in the Black Hills of South Dakota, has already proven itself to be the most sensitive detector in the hunt for dark matter, the unseen stuff believed to account for most of the matter in the universe. Now, a new set of calibration techniques employed by LUX scientists has again dramatically improved the detector's sensitivity.
They sound like futuristic weapons, but electron guns are actually workhorse tools for research and industry: They emit streams of electrons for electron microscopes, semiconductor patterning equipment and particle accelerators, to name a few important uses. Now scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have figured out how to increase these electron flows 13,000-fold by applying a single layer of diamondoids - tiny, perfect diamond cages - to an electron gun's sharp gold tip.
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have found a simple new way to study very delicate biological samples - like proteins at work in photosynthesis and components of protein-making machines called ribosomes - at the atomic scale using SLAC's X-ray laser.
A team led by Michael Zingale of Stony Brook University is exploring the physics of Type Ia supernovas using the Titan supercomputer at the US Department of Energy's (DOE's) Oak Ridge National Laboratory. The team's latest research focuses on a specific class of Type Ia supernovas known as double-detonation supernovas. This year, the team completed a three-dimensional (3-D), high-resolution investigation of the thermonuclear burning a double-detonation white dwarf undergoes before explosion. The study expands upon the team's initial 3-D simulation of this supernova scenario, which was carried out in 2013.
Peering into the seething soup of primordial matter created in particle collisions at the Relativistic Heavy Ion Collider (RHIC) -- an "atom smasher" dedicated to nuclear physics research at the U.S. Department of Energy's Brookhaven National Laboratory -- scientists have come to a new understanding of how particles are produced in these collisions.
Researchers from Caterpillar and the U.S. Department of Energy's Argonne National Laboratory conducted a proof of principle study that shows that high-energy synchrotron X-rays from the Advanced Photon Source can provide a new, affordable way for industry to optimize the mechanical and physical properties of cast iron in the manufacturing process.
Oak Ridge Graph Analytics for Medical Innovation (ORiGAMI) supplies researchers with an advanced data tool for literature-based discovery that has the potential to accelerate medical research and discovery.

Scientists have discovered new details about how "cloaking" proteins protect the toxin that causes botulism, a fatal disease caused most commonly by consuming improperly canned foods. That knowledge and the cloaking proteins themselves might now be turned against the toxin -- the deadliest known to humankind.
