Energy Efficiency Gaming computers offer huge, untapped energy savings potential
In the world of computer gaming, bragging rights are accorded to those who can boast of blazing-fast graphics cards, the most powerful processors, the highest-resolution monitors, and the coolest decorative lighting. They are not bestowed upon those crowing about the energy efficiency of their system. If they were, gaming computers worldwide might well be consuming billions of dollars less in electricity use annually, with no loss in performance, according to new research from Berkeley Lab.
Public Release: 25-Aug-2015 NREL helps federal agencies reach new efficiency targets
When it comes to energy use, what the federal government wants is more of less. That means fewer greenhouse gases, fewer buildings powered solely by electricity generated from fossil fuels, and fewer gas-guzzling fleets on the road.

Proceedings of the National Academy of Sciences New mathematics advances the frontier of macromolecular imaging
To see proteins in their native environment, scientists can blast powerful X-rays at tiny volumes of proteins in solution. Resulting 'diffraction patterns' can then be interpreted to reconstruct information about the protein's molecular structure. An emerging technique called fluctuation X-ray scattering could provide more detail than traditional solution scattering. But a major limitation for FXS has been a lack of mathematical methods to efficiently interpret the data. That's where Berkeley Lab's M-TIP comes in.

Atmospheric Chemistry and Physics Playing 'tag' with pollution lets scientists see who's 'it'
Using a climate model that can tag sources of soot and track where it lands, researchers have determined which areas around the Tibetan Plateau contribute the most soot -- and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes. The study, which appeared in Atmospheric Chemistry and Physics in June, might help policy makers target pollution reduction efforts.

Nature Communications 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.
