 AMBIOScientists put attitudes toward tigers on the map It's easier to feel positive about the endangered tiger in your backyard if you live on the good side of town. Neil Carter, a Ph.D. student who has spent years studying how people and tigers co-exist in Nepal, created a map of attitudes toward tigers -- a clear plotting of the haves, the have-nots, and how social status shapes different views of wildlife conservation.

Proceedings of the National Academy of SciencesEcological forces structure your body's personal mix of microbes Environmental conditions have a stronger influence on the mix of microbes living in your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit the same individual. The findings are a step toward building a predictive model of the human microbiome to study how medical conditions change this massive biological system, identify how to promote beneficial microbiomes, and design interventions for hard-to-manage problems like chronic digestive inflammation.

Environmental Research Letters Researchers shed new light on supraglacial lake drainage Supraglacial lakes -- bodies of water that collect on the surface of the Greenland ice sheet -- lubricate the bottom of the sheet when they drain, causing it to flow faster. Differences in how the lakes drain can impact glacial movement's speed and direction, researchers from The City College of New York, University of Cambridge and Los Alamos National Laboratory report in "Environmental Research Letters."

Environmental Science and TechnologyStudy identifies Deepwater Horizon debris as likely source of Gulf of Mexico oil sheens A chemical analysis of oil sheens found floating recently at the ocean's surface near the site of the Deepwater Horizon disaster indicates that the source is pockets of oil trapped within the wreckage of the sunken rig. Both the Macondo well and natural oil seeps common to the Gulf of Mexico were confidently ruled out.

Coastal EngineeringLong-forgotten seawall protected New Jersey homes from Hurricane Sandy's powerful storm surges Two beachfront communities in New Jersey were hit hard by Hurricane Sandy, but one fared much better than the other thanks to a long-forgotten seawall buried beneath the sand. Virginia Tech coastal engineers and geoscientists say the finding illustrates the need for multi-levels of beach protection in oceanfront communities.

PeerJNew Web-enabled technology records the presence of species by analyzing their sounds Identifying, and monitoring the fluctuations of thousands of species in tropical ecosystems is a difficult challenge, but newly developed technology now makes it much easier. Scientists report on new cyberinfrastructure which enables real-time acoustic recording and subsequent species identification in remote locations around the world. Thousands of audio recordings of tropical birds, frogs, monkeys, and insects in Puerto Rico and Costa Rica have been captured (using automated stations) and analyzed to identify the species concerned.

Proceedings of the National Academy of SciencesScientists outline long-term sea-level rise in response to warming of planet A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms. This is one of the first analyses to combine four major contributors to potential sea level rise into a collective estimate, and compare it with evidence of past sea-level responses to global temperature changes.

ScienceRobotic frogs help turn a boring mating call into a serenade With the help of a robotic frog, biologists have discovered that two wrong mating calls can make a right for female túngara frogs. The "rather bizarre" result may provide insight into how complex traits evolve by hooking together much simpler traits.

International Conference on Artificial Intelligence in EducationStudy finds clues on how to keep kids engaged with educational games If you want teams of students to stay engaged while playing educational games, you might want them to switch seats pretty often. That's one finding from a pilot study that evaluated how well middle school students were able to pay attention to game-based learning tasks.

Parasites & VectorsBlack-legged ticks linked to encephalitis in New York state Ostfeld concludes: "When patients present with encephalitis symptoms in areas with high levels of Lyme disease, especially during the summer, physicians need to consider Powassan encephalitis. While rare, it's associated with significant complications. There is no vaccine or specific antiviral therapy, the best strategy remains prevention."

Nature NanotechnologyCarnegie Mellon researchers develop artificial cells to study molecular crowding and gene expression A team of scientists at Carnegie Mellon University has approximated molecular crowding in an artificial cellular system and found that tight quarters help the process of gene expression, especially when other conditions are less than ideal. The researchers report their findings in an advance online publication by the journal Nature Nanotechnology.

Nature GeoscienceScientists solve a 14,000-year-old ocean mystery At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended -- as mysteriously as it began -- just a few hundred years later.

Nature GeoscienceSome volcanoes 'scream' at ever-higher pitches until they blow their tops Swarms of small earthquakes often precede a volcanic eruption. They can reach such rapid succession that they create a "harmonic tremor" that resembles sound made by some musical instruments. A new analysis of an eruption sequence at Alaska's Redoubt Volcano in March 2009 shows the harmonic tremor glided to substantially higher frequencies and then stopped abruptly just before six of the eruptions.

Nature CommunicationsSculpting flow Researchers from UCLA, Iowa State and Princeton reported results in Nature Communications on a new way of sculpting tailor-made fluid flows by placing microscale pillars in microfluidic channels. The method could allow clinicians to better separate white blood cells in a sample, increase mixing in industrial applications, and more quickly perform lab-on-a-chip-type operations. Using TACC's Ranger and Stampede supercomputers, the researchers ran more than 1,000 simulations representing combinations of speeds, thicknesses, heights or offsets that produce unique flows.

GeologyScientists cast doubt on theory of what triggered Antarctic glaciation A team of US and UK scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica's ice sheet began forming. Ian Dalziel of the University of Texas at Austin and his colleagues report finding an ancient volcanic arc in the Scotia Sea that might have prevented the Antarctic Circumpolar Current from forming until millions of years after Antarctic glaciation began.

ScienceDistant quakes trigger tremors at US waste-injection sites, says study Large earthquakes from distant parts of the globe are setting off tremors around waste-fluid injection wells in the central United States, says a new study. Furthermore, such triggering of minor quakes by distant events could be precursors to larger events at sites where pressure from waste injection has pushed faults close to failure, say researchers. Among the sites covered are central Oklahoma, western Texas and southern Colorado.

Proceedings of the National Academy of SciencesJagged graphene edges can slice into cell membranes Researchers from Brown University have shown how tiny graphene sheets can be big trouble for cells. Sharp corners and jagged edges on the sheets puncture cell membranes, allowing the sheet to enter the cell and disrupt function. The new understanding of how graphene interacts with cells could lead to safer production of this important nanomaterial.

Environmental Science & TechnologyStanford researchers say 'peak oil' concerns should ease Should concerns about "peak oil" focus on demand for oil rather than dwindling supplies of it? Yes, according to a new analysis. Limits to consumption by the wealthy, better fuel efficiency and lower priced alternative fuels should begin driving down demand for oil around 2035. That's good news overall, but policymakers should pay attention to the mix of substitutes that will replace conventional oil.
