 PLOS ONESalmonella infection is a battle between good and bad bacteria in the gut A new study in PLOS ONE that examined food poisoning infection as-it-happens in mice revealed harmful bacteria, such as a common type of Salmonella, takes over beneficial bacteria within the gut amid previously unseen changes to the gut environment. The results provide new insights into the course of infection and could lead to better prevention or new treatments.

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.

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.

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.

Nature GeneticsSelf-fertilizing plants contribute to their own demise Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy -- known as selfing -- guarantees reproduction but, over time, leads to reduced diversity and the accumulation of harmful mutations. A new study published in the scientific journal Nature Genetics shows that these negative consequences are apparent across a selfing plant's genome, and can arise more rapidly than previously thought.

Nature CommunicationsStanford scientists create novel silicon electrodes that improve lithium-ion batteries Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products. The scientists developed a new technique for producing low-cost, silicon-based batteries with potential applications for a wide range of electrical devices.

Proceedings of the National Academy of SciencesSalmonella uses protective switch during infection For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment during infection and might protect it from harm, researchers report this week online in the Proceedings of the National Academy of Sciences Early Edition.

Nature GeoscienceClimate researchers discover new rhythm for El Niño Why El Niño peaks around Christmas and ends quickly by February to April has been a long-standing mystery. The answer lies in an interaction between El Niño and the annual cycle that results in an unusual tropical Pacific wind pattern with a period of 15 months, according to a team of scientists at the University of Hawai'i at Manoa. Their study appears in the May 26, 2013, online issue of Nature Geoscience.

Environmental Science & TechnologyGoing green: Nation equipped to grow serious amounts of pond scum for fuel A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year in the United States, one-twelfth of the country's yearly needs. For the best places to produce algae for fuel, think hot, humid and wet. Especially promising are the Gulf Coast and the Southeastern seaboard.
