Titan helps unpuzzle decades-old plutonium perplexities
First produced in 1940, plutonium is one of the most electronically complicated elements on Earth -- and because of its complexities, scientists have been struggling to prove the existence of its magnetic properties ever since. Finally, that struggle is over, thanks to a timely combination of theory, algorithm and code developments, neutrons experiments, and Titan -- the second-most-powerful supercomputer in the world.

Los Alamos explores hybrid ultrasmall gold nanocluster for enzymatic fuel cells
With fossil-fuel sources dwindling, better biofuel cell design is a strong candidate in the energy field. In research published in the Journal of the American Chemical Society, Los Alamos researchers and external collaborators synthesized and characterized a new DNA-templated gold nanocluster (AuNC) that could resolve a critical methodological barrier for efficient biofuel cell design.

Techniques could create better material, design in high-consequence uses
Sandia National Laboratories is studying additive manufacturing and its potential for high-consequence applications. Two aspects of that effort are to understand both the properties of newly formed materials and how to design to get just what's needed without over-designing.

Mysterious neutrinos take the stage at SLAC
To find out more about the elusive particles and their potential links to cosmic evolution, invisible dark matter and matter's dominance over antimatter in the universe, the Department of Energy's SLAC National Accelerator Laboratory is taking on key roles in four neutrino experiments: EXO, DUNE, MicroBooNE and ICARUS.

Muon g-2 magnet successfully cooled down and powered up
Two years ago, scientists on the Muon g-2 experiment successfully brought a fragile, expensive and complex 17-ton electromagnet on a 3,200-mile land and sea trek from Brookhaven National Laboratory in New York to Fermilab in Illinois. This week, the ring -- now installed in a new, specially designed building at Fermilab -- was successfully cooled down to operating temperature (minus 450 degrees Fahrenheit) and powered up, proving that even after a decade of inactivity, it remains a vital and viable scientific instrument.

Q&A: Biologist describes milestone in watching proteins boogie
Using an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory, researchers have for the first time directly seen myoglobin move within quadrillionths of a second after a bond breaks and the protein releases a gas molecule. The Linac Coherent Light Source X-ray laser is a DOE Office of Science User Facility, and its short, bright pulses were essential for observing these ultrafast, atomic-scale motions.

Scientists use lasers to simulate shock effects of meteorite impact on silica
Scientists used high-power laser beams at the Department of Energy's SLAC National Accelerator Laboratory to simulate the shock effects of a meteorite impact in silica, one of the most abundant materials in the Earth's crust. They observed, for the first time, its shockingly fast transformation into the mineral stishovite -- a rare, extremely hard and dense form of silica.

Making the most from carbon in plants
Researchers are looking for more effective ways to get at all the carbon in biomass to create more energy and biochemicals. However, a lot of the carbon is in lignin -- support tissues in plants, which makes up about a third of the biomass. International teams of scientists are utilizing EMSL's expertise and capabilities to better understand how lignin can be efficiently deconstructed to release its carbon for a more renewable and sustainable energy future.

Fortifying computer chips for space travel
One of the most long-lived and active space-chip testing programs is at the Berkeley Lab. Since 1979, most American satellites and many major NASA projects including the Mars Rover Curiosity, the space shuttles, and the new Orion capsule, have had one or more electronic components go through Berkeley Lab's cyclotron.

Researchers see 'spin current' in motion for the first time
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have for the first time seen a spin current -- an inherent magnetic property common to all electrons -- as it travels across materials. The result, which revealed a surprising loss of current along the way, is an important step toward realizing a next-generation breed of electronics known as 'spintronics.'

Time-lapse analysis offers new look at how cells repair DNA damage
Time-lapse imaging can make complicated processes easier to grasp. Berkeley Lab scientists are using a similar approach to study how cells repair DNA damage. Microscopy images are acquired about every thirty minutes over a span of up to two days, and the resulting sequence of images shows ever-changing hotspots inside cells where DNA is under repair.

Q&A: Researchers explain a strange high-intensity result at SLAC's X-ray laser
At extremely high intensities, X-rays stop behaving like the ones in your doctor's office and begin interacting with matter in very different ways. This 'nonlinear' X-ray behavior can only be seen at X-ray free-electron lasers. Recent experiments at the Department of Energy's SLAC National Accelerator Laboratory have revealed a new, unexpected twist in that behavior that may be one for the textbooks and could change the way these powerful lasers probe matter.

X-ray duo's research helps launch human trial for treatment of arsenic poisoning
Graham George and Ingrid Pickering, a husband and wife X-ray research team, have worked for decades to understand how contaminants in water and soil are taken up by the body and affect human health. Much of that research has taken place at the Stanford Synchrotron Radiation Lightsource (SSRL), a DOE Office of Science User Facility at SLAC National Accelerator Laboratory, where both are former staff scientists.

Carbon number crunching
A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.

Viral comparisons
An Oak Ridge National Laboratory team of comparative genomics and computational science researchers compared approximately 4,000 complete virus genomes downloaded from a public database known as GenBank. By compressing the sequence files, the team created a virus dendrogram that maps out the relationships among all the different virus families.
