Huge grains of copper promote better graphene growthto technology insiders graphene is certified a big deal.
Graphene-based electronics promise advances such as faster internet speeds cheaper solar cells novel sensors space suits spun from graphene yarn and more.
and Technology (NIST) in Boulder Colo. may help bring graphene's promise closer to reality.
While searching for an ideal growth platform for the material investigators developed a promising new recipe for a graphene substrate:
--but their relative bulk enables them to survive the high temperatures needed for graphene growth explained NIST researcher Mark Keller.
The inability of most copper films to survive this stage of graphene growth has been one problem preventing wafer-scale production of graphene devices Keller said.
To demonstrate the viability of their giant-grained film the researchers successfully grew graphene grains 0. 2 millimeters in diameter on the new copper surface.
and at great cost by eliminating some of the trial and error in identifying new sites on proteins that could be manipulated more easily to treat disease said Rice biological physicist Jos Onuchic.
Onuchic and his team integrated its direct coupling analysis (DCA) method based on genomic databases with structure-based models (SBM) of proteins to produce simulations of how proteins progress through different functional states.
when it comes to choosing the best site for egg-laying. Using behavioural assays researchers at the Max Planck Institute for Chemical Ecology in Jena Germany
For egg-laying insects selecting the best site to lay eggs is crucial for the survival of the eggs and larvae.
It is fascinating that a complex behaviour such as choosing an egg-laying site can be broken down into multiple subroutines that have such a simple genetic basis says Marcus Stensmyr.#

Using computer models to examine flower colors as bees would see them the team addressed how pollinator vision had shaped flower evolution.
Now the same team has combined the field findings with new computer models of rabies transmission and data from infection studies using captive vampire bats to show that culling has minimal effect on containing the virus
Thousands of computer simulations were run and the most successful models demonstrated that a single isolated vampire bat colony cannot maintain the rabies virus over time Frequent movement of infectious bats between colonies is needed to keep the rabies virus at levels consistent with the field observations.
Rohani and colleagues say that such a phenomenon has recently been observed in controlled badger culls in the United kingdom where disruption of badger social dynamics and subsequent dispersal led to increased tuberculosis transmission in cattle at neighboring sites.
Nordlander discovered the quantum mechanical effects in these materials are connected strongly to the size of the gap between the shell and the core.
Nordlander used computer simulations to investigate the discrepancies between classical electromagnetics and quantum mechanics and precisely where the two theories diverge in both gold and aluminum nanomatryushkas.
In both cases quantum tunneling through the gap allowed plasmons to resonate as though the core

#Delaying resistance to Bt corn in western corn rootwormcorn that contains proteins that protect it from insect damage has been grown in the U s. since the mid-1990s.
Known as Bt corn because the proteins are derived from a bacterium called Bacillus thuringiensis these plants have been grown widely by farmers.
While Bt corn has been highly effective against the European corn borer it has been less so against the western corn rootworm
which has been documented to show resistance to the Bt proteins. In a new article in the Journal of Integrated Pest Management--an open-access peer-reviewed extension journal--the authors explain why this has occurred
In Resistance to Bt Corn by Western Corn Rootworm (Coleoptera: Chrysomelidae) in the U s. Corn belt Drs.
Aaron Gassmann (Iowa State university) Michael Gray (University of Illinois) Eileen Cullen (University of Wisconsin) and Bruce Hibbard (University of Missouri) examine why Bt corn has been more effective against the European corn borer
First Bt proteins intended for the European corn borer are produced at a higher dose than the ones intended for rootworms;
which increases the chances of potentially resistant insects mating with non-resistant ones that have not been exposed to Bt proteins;
One approach to IRM is not necessarily optimal for all insect pests according to the authors who recommend that growers use the following IPM approaches to delay further rootworm resistance to Bt corn:
-Occasionally rotate to a non-Bt corn hybrid and consider use of a rootworm soil insecticide during planting.
-Consider using corn that contains different Bt proteins than ones that may have performed poorly in the past. -Consider using pyramided Bt hybrids
which is defined as corn that contains multiple Bt proteins targeting corn rootworm. -If crop rotation is not an option
and corn containing multiple Bt proteins is not available suppression of rootworm adults by using insecticides for one
or two growing seasons may be an appropriate remediation step. -Most importantly implement a long-term integrated approach to corn rootworm management based on scouting information and knowledge of corn rootworm densities that uses multiple tactics such as rotation with other crops
rotation of Bt proteins and the use of soil insecticides at planting with a non-Bt hybrid.
if the relationship between density and mortality varies with site quality as ponderosa pine stands developed.
and Analysis group these researchers found that site quality affected the relationship between density and mortality.
The research also confirmed the added value of such long-term study sites which allow new questions to be addressed that were included not in the original studies.
which is the cross sectional area of all trees in a stand measured at breast height is affected not by thinning ponderosa pine stands to half the normal basal area of a specific site quality.
Pioneering excavations within the sacred Maya Devi Temple at Lumbini Nepal a UNESCO World Heritage site long identified as the birthplace of The buddha uncovered the remains of a previously unknown sixth-century B c. timber structure
and strengthened site management to ensure Lumbini's protection. These discoveries are very important to better understand the birthplace of The buddha said Ram Kumar Shrestha Nepal's minister of culture tourism and civil aviation.
The government of Nepal will spare no effort to preserve this significant site. Buddhist tradition records that Queen Maya Devi the mother of The buddha gave birth to him
while holding on to the branch of a tree within the Lumbini Garden midway between the kingdoms of her husband and parents.

Scientists determine methane levels by examining ice cores from polar regions. Gas bubbles containing ancient air trapped within the ice can be analyzed
Ice cores from Greenland had higher methane levels than those from Antarctica because there are greater methane emissions in the Northern hemisphere.

But we also saw a significant reduction--11 percent--in the risk of dying from cancer added Fuchs who is affiliated also with the Channing Division of Network Medicine at Brigham
For the new research the scientists were able to tap databases from two well-known ongoing observational studies that collect data on diet and other lifestyle factors and various health outcomes.
Sophisticated data analysis methods were used to rule out other factors that might have accounted for the mortality benefits.
Returning to the same grass-invaded field sites in Hawaii volcanoes national park that she used in her 1990-1995 studies D'Antonio
We permanently marked sites we had set up and were able to go back and gain insight into how plant invasions changed over time without management said D'Antonio who also is a professor in the Department of Ecology Evolution and Marine Biology.
When D'Antonio and Yelenik revisited the study sites they noticed that the invasive exotic perennial grasses (primarily an African invader called Melinis minutiflora) were dying so they decided to repeat measures of nutrient cycling and plant community change.
Data showed that in the past 17 years nitrogen mineralization rates at the sites dominated by the exotic grasses declined by half returning them to pre-invasion levels.

#Algorithm identifies individual grains in planetary regolithinstruments on the Curiosity Mars rover not only measure the chemistry of rocks elemental abundances of soils
and segmentation algorithm specifically to aid planetary scientists with this very basic but often difficult task.
The algorithm implemented in Mathematica uses a variety of image processing steps to segment the image first into coarser (foreground) and finer (background) grains.
The semi-automated algorithm while comparing favorably with manual (human) segmentation provides better consistency across multiple images than a human.
The researchers are exploring the use of this algorithm to quantify grain sizes in the images from the Mars Exploration Rovers Microscopic Imager (MI) as well as Curiosity's Mars Hand Lens Imager (MAHLI.
Applications extend to terrestrial data from less accessible sites such as deep lake basins or undisturbed river bed sediments.

In a new study the team of 15 university Google and government researchers reports a global loss of 2. 3 million square kilometers (888000 square miles) of forest between 2000 and 2012
Their study published online on November 14 in the journal Science documents the new database including a number of key findings on global forest change.
and five other UMD geographical science researchers drew on the decades-long UMD experience in the use of satellite data to measure changes in forest and other types of land cover.
Landsat 7 data from 1999 through 2012 were obtained from a freely available archive at the United states Geological Survey's center for Earth Resources Observation
and Science (EROS). More than 650000 Landsat images were processed to derive the final characterization of forest extent and change.
The analysis was made possible through a collaboration with colleagues from Google earth Engine who implemented the models developed at UMD for characterizing the Landsat data sets.
Google earth Engine is a massively parallel technology for high-performance processing of geospatial data and houses a copy of the entire Landsat image catalog.
What would have taken a single computer 15 years to perform was completed in a matter of days using Google earth Engine computing.
This mapping database which will be updated annually quantifies all forest stand-replacement disturbances whether due to logging fire disease or storms.
Brazil used Landsat data to document its deforestation trends then used this information in its policy formulation and implementation.
Researchers at the University of Exeter and Colorado State university used a computer model to demonstrate that providing forest conservation measures are in place the Amazon rainforest may be more able to withstand periods of drought than has been estimated by other climate models.

#Meteor Raspberry Pi cluster used to teach parallel computingresearchers at the San diego Supercomputer Center (SDSC) at the University of California San diego have built a Linux cluster using 16 Raspberry Pi computers as part of a program to teach children
and adults the basics of parallel computing using a simple model that demonstrates how computers leverage their capacity when working together.
for high-performance computing to be held November 18-22 in Denver Colorado. SDSC staff will hold a friendly gaming competition using Meteor
which will be connected to a large tiled display wall of LCD panels during the show's exhibit hours in the SDSC display space (booth#3313).
and adults about parallel computing by providing an easy-to understand tangible model of how computers can work together said Rick Wagner SDSC's manager for high-performance computing (HPC).
More importantly we present Meteor in a fun informal learning environment where students can try their hands at gaming competition while learning about the benefits of parallel programming.
Like Comet Meteor is all about high-performance computing for the 99 percent said SDSC Director Michael Norman.
It's about increasing computing access on a broad scale to support data-enabled science and engineering across education as well as research.
and configuring computers to work in concert; and as data networks become faster multi-core processors become the norm
and accelerators such as GPUS (graphic processing units) become more prevalent the skills required to make these elements work synchronously are critical to advancing scientific research and discovery.
Currently the majority of computer science degree curriculums contain relatively few courses in parallel programming and distributed architecture at the undergraduate level and below but the basic concepts aren't difficult said Wagner.
and program current hardware. Wagner has started already developing a course curriculum in addition to presenting a workshop at XSEDE13.
Beyond games students also developed hybrid applications that used both the CPUS (central processing units) on the Raspberry Pis in addition to the GPUS.
With the start of the Fall 2013 term Wagner in collaboration with Brett Stalbaum a UC San diego researcher specializing in information theory database
and software development began teaching a visualization and computing course using Meteor to help visualize data generated by SDSC's HPC systems.
The potential teaching mechanisms are open-ended at this time but could lead to such things as project-based learning
taking a complex problem and allowing someone to solve it in a simple unconstrained environment as well as encouraging students to design new hardware that we haven't yet imagined.

Systems that currently allow users complete anonymity are being abusedthe World wide web is in many ways still the Wild west.
Though a large portion of internet traffic is monitored and traceable systems like the Tor Project allow users to post
and others communicate in private away from the prying eyes of the Internet at-large. These systems however have been degraded by criminals who use them to support unlawful activities.
Yong Guan an associate professor of electrical and computer engineering and his students have devised a system that offers anonymity for honest users and accountability for dishonest users.
The layers of encryption disguise the origin of the message thus providing anonymity but at a high computing cost.
Bouncing messages around a network and adding a layer of encryption with each bounce takes time and computing power.
If a criminal uses the service to send a malicious message the network expends the same computing power to send that message
and requires the cooperation of the system's key generator and internet service provider's registration database.
or sign a message without the source's signing key it would have to solve a problem that is incredibly difficult even for the fastest computers.
and the internet service provider's registration database and use this data with the message's AFGH re-encryption key to determine the source of the message.
Guan envisions his system as a way for law enforcement to track down senders of threatening emails and those who leak important documents.
THEMIS represents the first system to provide both anonymity and accountability in an incentive-compatible fashion and the first anonymous network to use multi-hop proxy re-encryption.
The next step Guan says is to test it on a large scale over the Internet. This way we can really see how well it performs.

which fix a modest amount of nitrogen that mostly stays on site in soils trees and shrubs.
The research team conducted a synthesis of data collected from more than 600 secondary forest sites from 74 previous studies describing carbon pools
Each site had comparable data for a nearby site that was relatively free of human disturbance.
Their results suggest that trees at drier sites buy insurance for their leaves in the form of beefed-up ant protection
and Azteca ants (Azteca pittieri) Pringle and her colleagues studied the interaction at 26 sites in seasonally dry tropical forests along the Pacific coast of southern Mexico and Central America.
The coastal sites span 1426 miles with annual precipitation increasing fourfold from the northernmost to the southernmost site.
and defense of leaves by ants--was greater at sites with longer dry seasons. Laurel trees don't feed ants sugar directly.
Pringle and her colleagues found that at the drier study sites laurel trees support more scale insects which in turn produce more honeydew.
Defoliation is a greater potential threat at the drier sites because laurels there have smaller carbon reserves
The fact that laurel trees at drier sites pay their ant protectors higher wages suggests that the potential costs of defoliation outweigh the relatively modest price of supporting more ants.
which ants protect trees from rare but life-threatening defoliation events best fit observations from the 26 sites.
Like farmers buying crop insurance the trees at drier sites appear to be hedging their bets:
The observed differences between dry and wet sites may therefore reflect genetic adaptations to local conditions the researchers suggest.

#Oldest ice core: Finding a 1. 5 million-year record of Earths climatehow far into the past can ice-core records go?
Scientists have identified now regions in Antarctica they say could store information about Earth's climate
Ice cores contain little air bubbles and thus represent the only direct archive of the composition of the past atmosphere says Hubertus Fischer an experimental climate physics professor at the University of Bern in Switzerland
However drilling deeper to collect a longer ice core does not necessarily mean finding a core that extends further into the past.
Crucially they also found that an ice core extending that far into the past should be between 2. 4 and 3-km long shorter than the 800000-year-old core drilled in the previous expedition.
We were surprised completely to see so many bay cats at these sites in Borneo where natural forests have been logged so heavily for the timber trade.
