 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.

NREL adds eyes, brains to occupancy detection It's a gnawing frustration of modern office life. You're sitting quietly -- too quietly -- in an office or carrel, and suddenly the lights go off.

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.

Journal Of Quaternary SciencePenn-led research maps historic sea-level change on the New Jersey coastline A new study led by the University of Pennsylvania's Benjamin P. Horton, an associate professor in the Department of Earth and Environmental Science, relied upon fossil records of marshland to reconstruct the changes in sea level along the New Jersey coast going back 10,000 years.

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.

Nature MethodsA new cost-effective genome assembly process Genome assembly, the molecular equivalent of trying to put together a multi-million piece jigsaw puzzle without knowing what the picture on the cover of the box is, remains challenging due to the very large number of very small pieces, which must be assembled using current approaches. As reported May 5 online in the journal Nature Methods, a collaboration involving DOE JGI researchers has resulted in an improved and fully automated workflow for genome assembly.

Global Change BiologyNitrogen has key role in estimating CO2 emissions from land use change A new global-scale modeling study that takes into account nitrogen -- a key nutrient for plants -- estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen. Plant regrowth -- and therefore carbon assimilation by plants -- is limited by nitrogen availability, causing other studies to overestimate regrowth and underestimate net emissions from the harvest-regrowth cycle.

NREL survey shows dramatic improvement in B100 biodiesel quality The latest national survey of 100 percent biodiesel "blend stock" samples by the US Department of Energy's National Renewable Energy Laboratory found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications. The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers -- along with reliable operation of the nation's vehicles powered by biodiesel blends.

Nature Climate ChangeCutting specific pollutants would slow sea level rise With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow down sea level rise. Reductions in the four pollutants that cycle comparatively quickly through the atmosphere could forestall the rate of sea level rise by roughly 25 to 50 percent.
