Nature Photonics
Short wavelength plasmons observed in nanotubes
Working at the Advanced Light Source, Berkeley Lab researchers have observed 'Luttinger-liquid' plasmons in metallic single-walled nanotubes. This holds great promise for novel plasmonic and nanophotonic devices over a broad frequency range, including telecom wavelengths.

New computer model could explain how simple molecules took first step toward life
Sergei Maslov, a computational biologist at the US Department of Energy's Brookhaven National Laboratory and adjunct professor at Stony Brook University, and Alexei Tkachenko, a scientist at Brookhaven's Center for Functional Nanomaterials, have developed a model that explains how simple monomers could rapidly make the jump to more complex self-replicating polymers. What their model points to could have intriguing implications for the origins of life on Earth and CFN's work in engineering artificial self-assembly at the nanoscale.

Young scientist discovers magnetic material unnecessary to create spin current
Research at Argonne indicates that you don't need a magnetic material to create spin current from insulators--with important implications for the field of spintronics and the development of high-speed, low-power electronics that use electron spin rather than charge to carry information.

ORNL researchers make scalable arrays of 'building blocks' for ultrathin electronics
For the first time, researchers at the Department of Energy's Oak Ridge National Laboratory have combined a novel synthesis process with commercial electron-beam lithography techniques to produce arrays of semiconductor junctions in arbitrary patterns within a single, nanometer-thick semiconductor crystal. The process transforms patterned regions of one existing, single-layer crystal into another. The two semiconductor crystals formed sharp junctions, the desired building blocks of electronics. Nature Communications reports the accomplishment.

Simulations lead to design of near-frictionless material
Argonne scientists used the Mira supercomputer to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. ALCF researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.

Curiosity rover finds evidence of Mars' primitive continental crust
The ChemCam laser instrument on NASA's Curiosity rover has turned its beam onto some unusually light-colored rocks on Mars, and the results are surprisingly similar to Earth's granitic continental crust rocks. This is the first discovery of a potential 'continental crust' on Mars.

Study finds that future deployment of distributed solar hinges on electricity rate design
Future distributed solar photovoltaic (PV) deployment levels are highly sensitive to retail electricity rate design, according to a newly released report by researchers from Berkeley Lab. The study also explores the feedback effects between retail electricity rates and PV deployment, and suggests that increased solar deployment can lead to changes in PV compensation levels that either accelerate or dampen further deployment.
