Advanced MaterialsBeyond silicon: Transistors without semiconductors Scientists at Michigan Technological University have built a nanoscale transistor that works at room temperature. The device, only 20 nanometers wide, is made of gold quantum dots mounted on boron nitride nanotubes. It was built in collaboration with colleagues at Oak Ridge National Lab.

MutagenesisBerkeley Lab confirms thirdhand smoke causes DNA damage A study led by researchers from Lawrence Berkeley National Laboratory has found for the first time that thirdhand smoke -- the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out -- causes significant genetic damage in human cells.

Proceedings of the National Academy of SciencesLess is more: Novel cellulose structure requires fewer enzymes to process biomass to fuel Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research from Los Alamos National Laboratory and the Great Lakes Bioenergy Research Center. Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic -- or non-food -- plant-derived biomass.

Molecular Systems BiologyExpressly unfit for the laboratory A new Berkeley Lab study challenges the orthodoxy of microbiology, which holds that in response to environmental changes, bacterial genes will boost production of needed proteins and decrease production of those that aren't. The study found that for bacteria in the laboratory there was little evidence of adaptive genetic response.

Astronomy & AstrophysicsUnusual supernova is doubly unusual for being perfectly normal Type Ia supernovae are indispensable milestones for measuring the expansion of the universe. With definitive measures of Supernova 2011fe, the "Backyard Supernova" that thrilled amateur and professional astronomers alike in the summer of 2011, the Nearby Supernova Factory led by Lawrence Berkeley National Laboratory demonstrates that this unusually close-by Type Ia is such a perfect example of its kind that future Type Ia's -- and models meant to explain their physics -- must be measured against it.

Proceedings of the National Academy of SciencesNovel enzyme from tiny gribble could prove a boon for biofuels research Researchers from the United Kingdom, the Energy Department's National Renewable Energy Laboratory, and the University of Kentucky have recently published a paper describing a novel cellulose-degrading enzyme from a marine wood borer Limnoria quadripunctata, commonly known as the gribble.

Advanced MaterialsPrinting tiny batteries Three-dimensional printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.

Stop hyperventilating, say energy efficiency researchers A single advanced building control now in development could slash 18 percent -- tens of thousands of dollars -- off the overall annual energy bill of the average large office building, with no loss of comfort. Instead of running ventilation full blast whenever just a single person is in the room, customize the amount of ventilation based on the number of people actually present.

International Society for Microbial Ecology JournalBerkeley Lab team uncovers secrets of biological soil crusts A team of Berkeley Lab researchers has performed molecular level analysis of desert biological soil crusts -- living ground cover formed by microbial communities -- to reveal how long-dormant cyanobacteria become activated by rainfall then resume dormancy when the precipitation stops.

NatureGenetic maps of ocean algae show bacteria-like flexibility A seven-year effort by 75 researchers from 12 countries to map the genome of the coccolithophore, Emiliania huxleyi, has revealed a set of core genes that mix and match with a set of variable genes that likely allows E. huxleyi, or Ehux, to adapt to different environments. Their results are described in the latest issue of Nature.

NatureChalking up a marine blooming alga: Genome fills a gap in the tree of life Carbon dioxide is released when the calcium carbonate "armor" of the photosynthetic alga Emiliania huxleyi forms, but Ehux can trap as much as 20 percent of organic carbon derived from CO2 in some marine ecosystems. Its versatility in either contributing to primary production or adding to CO2 emissions makes Ehux a critical player in the marine carbon cycle. The Ehux genome sequence was compared with other algal sequences in the June 12, 2013 edition of Nature.

Journal of Analytical Atomic SpectrometryResearch paints new picture of 'dinobird' feathers The first complete chemical analysis of feathers from Archaeopteryx, a famous fossil linking dinosaurs and birds, reveals that the feathers were patterned--light in color, with a dark edge and tip--rather than all black, as previously thought. The X-ray study took place at SLAC's SSRL.

Nano Letters'Popcorn' particle pathways promise better lithium-ion batteries Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO4, or LFP), findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft. The research is reported in te journal Nano Letters, 2013, 13 (3), pp 866-872. Contact: Mike Janes

Nature MaterialsAmes Laboratory scientists discover new family of quasicrystals Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a new family of rare-earth quasicrystals using an algorithm they developed to help pinpoint them. Their research resulted in finding the only known magnetic rare earth icosahedral binary quasicrystals, now providing a "matched set" of magnetic quasicrystals and their closely related periodic cousins.
