Scientists capture ultrafast snapshots of light-driven superconductivity
A new study, based on an experiment at SLAC's X-ray laser, pins down a major factor behind the appearance of superconductivity -- the ability to conduct electricity with 100 percent efficiency -- in a promising copper-oxide material.

Simulation solves mystery of how liquid-crystal thin films disintegrate
Approximately four decades ago, theoreticians believed that only one of two mechanisms could explain rupture of liquid-crystal thin films. They also believed that these two mechanisms could not coexist. But 10 years ago experiments showed that these two mechanisms in many cases do coexist, according to Trung Nguyen of Oak Ridge National Laboratory, who ran unprecedented large-scale molecular dynamics simulations on Titan, America's fastest supercomputer, to model the beginnings of ruptures in thin films.

Generations of supercomputers pin down primordial plasma
Brookhaven Lab's Lattice Gauge Theory Group hunts for equations to describe the early universe and the forces binding matter together. Their search spans generations of supercomputers and parallels studies of the primordial plasma discovered and explored at Brookhaven's Relativistic Heavy Ion Collider.

Tracking the transition of early-universe quark soup to matter-as-we-know-it
By smashing together ordinary atomic nuclei at the Relativistic Heavy Ion Collider, scientists recreate the primordial soup of the early universe thousands of times per second. Using sophisticated detectors to track what happens as exotic particles emerge from the collision zone and 'freeze out' into more familiar forms of matter, they are turning up interesting details about how the transition takes place.

'Smart window' material may make better batteries
Windows that darken to filter out sunlight in response to electric current, function much like batteries. Now, X-ray studies at SLAC provide a crystal-clear view into how this color-changing material behaves in a working battery -- information that could benefit next-generation rechargeable batteries.

Tapping into the metabolome
Metabolomics -- a field often called "the last 'omics frontier" -- seeks to understand the fundamental metabolic workings of a cell in a changing environment. Scientists at EMSL use mass spectrometers, nuclear magnetic resonance, imaging devices and other cutting-edge instruments to glean the information to help produce better fuels, crops and other bioproducts.

Democratizing science with high-speed networks
For the first time, data collected and analyzed by a very remote user of the Department of Energy's National Center for Electron Microcopy via the Energy Sciences Network has been published. Because of this, scientists are optimistic about the future of remote microscopy for DOE-supported science.

Particle beam cancer therapy: The promise and challenges
Advances in accelerators built for fundamental physics research have inspired improved cancer treatment facilities. But will one of the most promising -- a carbon ion treatment facility -- be built in the US? Participants at a symposium organized by Brookhaven Lab for the 2014 AAAS meeting explored the science and surrounding issues.

CDMS result covers new ground in search for dark matter
Scientists looking for dark matter face a serious challenge: No one knows what dark matter particles look like. So their search covers a wide range of possible traits -- different masses, different probabilities of interacting with regular matter. Today, scientists on the Cryogenic Dark Matter Search experiment, or CDMS, announced they have shifted the border of this search down to a dark-matter particle mass and rate of interaction that has never been probed.

Early Edison users deliver results
Before any supercomputer is accepted at NERSC, scientists are invited to put the system through its paces during an "early science" phase. While the main aim of this period is to test the new system, many scientists are able to use the time to significantly advance their work.

The play-by-play of energy conversion: Catching catalysts in action
Before catalysis unfolds in a laboratory, scientists painstakingly assemble the materials and spark a reaction. But many experimental techniques only capture the static details before and after the reaction. Now, researchers at the US Department of Energy's Brookhaven National Laboratory have demonstrated an unprecedented ability to peer into the dynamic, real-time reactions blazing along at scales spanning just billionths of a meter, producing a sort of play-by-play view of the chemistry in action.

Small size enhances charge transfer in quantum dots
In a study just published in the journal Chemical Communications, scientists at the US Department of Energy's Brookhaven National Laboratory, Stony Brook University, and Syracuse University show that shrinking the core of a quantum dot can enhance the ability of a surrounding polymer to extract electric charges generated in the dot by the absorption of light.
