#Greenland ice cores show industrial record of acid rain, success of US Clean Air Actthe rise
UW researchers began their study of ice cores interested in smog not acid rain. They discovered a link between the two forms of pollution in the geologic record.
How much the nitrate concentrations in ice core records can tell about NOX and the chemistry in the past atmosphere is a longstanding question in the ice-core community said lead author Lei Geng a UW postdoctoral researcher in atmospheric sciences.
Unlike other gases short-lived NOX can't be measured directly from air bubbles trapped in ice cores.
Within a day or two most of the NOX changes into nitrate a water-soluble molecule essential to life that gets deposited in soil and snow.
Ice cores from Greenland and North american lake sediments showed the nitrogen-15 ratio gradually decreasing
and the final signal recorded in the Greenland ice cores is actually not just the nitrogen emission
The ice cores used in the study were collected in 2007 at Summit Station Greenland. Total amounts of nitrate for each year were measured
Acid air can also influence the reactivity of nitrate in snow and thus the preservation of nitrate in ice cores.
Other ice core records might also be affected by acidity in air Alexander said. No effect would be expected for stable gases like carbon dioxide
and preservation of other volatile compounds such as chlorine mercury or organic materials in ice cores.

Oxide-derived copper on the other hand is made of copper nanocrystals that are linked all together in a continuous network with well-defined grain boundaries.
The process of transforming copper oxide into metallic copper creates the network of nanocrystals. For the Nature study Kanan and Li built an electrochemical cell--a device consisting of two electrodes placed in water saturated with carbon monoxide gas.
Our models suggest that the nanocrystalline network in the oxide-derived copper was critical for achieving these results.

diselenide--a highly sought semiconductor that is similar to graphene but has better properties for making certain electronic devices like switchable transistors and light-emitting diodes.
The method for making two-dimensional molybdenum diselenide uses a technique known as chemical vapor deposition (CVD)
Unlike graphene which can now easily be made in large sheets many interesting 2-D materials remain difficult to synthesize.
In the Rice study Ajayan and colleagues tested their atomically thin layers of molybdenum diselenide by building a field effect transistor (FET) a commonly used device in the microelectronic industry.
because they have an atomic structure similar to graphene the pure carbon wonder materials that attracted the 2010 Nobel prize in physics.
Graphene and similar materials are referred often to as two-dimensional because they are only one atom thick.
Graphene has extraordinary electronic properties. For example its electron mobility is tens of thousands of times greater than that of TMDCS.
because their electronic properties are complementary to graphene. For example pure graphene has no bandgap--a useful electronic property that engineers can exploit to make FETS that are switched easily on and off.
As with many nanomaterials scientists have found that the physical properties of TMDCS change markedly when the material has nanoscale properties.
because direct-bandgap materials can be used to make switchable transistors and sensitive photodetectors. One of the driving forces in Rice's Department of Materials Science and Nanoengineering is the close collaborations that develop between the people who are focused on synthesis

or posted on the web as well as in store displays and signs. These spheres known as direct-to-consumer and point-of-purchase marketing are regulated not
In 2010 the tobacco industry spent $236 million in cigarette coupons and $22 million in Internet marketing.
Some of this Internet marketing infiltrates social media which is consumed widely by teens and young adults.
Since younger consumers are more price sensitive to the high cost of tobacco products a web ad offering a coupon could be perceived very favorably.
Tobacco manufacturers'websites where coupons are downloaded require visitors to prove they are not underage by inputting driver's license or social security numbers.
Norris Cotton Cancer Center prevention experts recommend stricter security for websites and increased enforcement for direct-to-consumer marketing.
TV tobacco use fell from 4. 96 instances per hour of programming (excluding advertising) in 1961 to 0. 29 instances per hour in 2010.

The depiction of smoking in other screen media such as cable TV and Youtube should be studied further in the United states
#Advantages, potential of computer-guided spinal surgeryin a series of research studies Cedars-Sinai spinal surgeons show that a new method of computer-guided spine surgery is beneficial for spinal reconstruction
Computer-guided surgical navigation technology delivers on quality and safety said J. Patrick Johnson MD a neurosurgery spine specialist and director of Spine Education and the Neurosurgery Spine Fellowship program in the Department of Neurosurgery.
The images are transferred to a computer which displays them on overhead monitors that allow precise tracking of surgical instruments as surgeons insert screws for reconstruction
because hardware was initially out of place. The Cedars-Sinai surgeons say they have cut these to nearly zero by using computer-guided methods.
The surgeons said the technology has others applications for treating spinal disorders serving as a tool to remove tumors decompress the spinal column

#Computer models soybean crop with 8. 5 percent more productivity, using 13 percent less watercrops that produce more
This dream is coming closer to reality for University of Illinois at Urbana-Champaign researchers who have developed a new computer model that can help plant scientists breed better soybean crops.

This approach then can help guide field programs by pointing to plants with particular combinations of traits already tested in the computer

and US Forest Service in the Ecological Society of America's journal Ecosphere last week but outlier project sites with good grouse habitat may yield clues to successful management scenarios.
That's why the team chose to look at ESR project sites. We have this problem with nonnative plants coming in changing the fire cycle
and shrub seeds to the site. In recent years BLM has moved to using native species when possible.
Arkle and colleagues examined 101 sites that burned once between 1990 and 2003. To select their sites they compiled a database of fires
and ESR projects from which they randomly chose a set of project sites with a gradient of precipitation and annual temperatures but similar soil types.
Treated plots were not much more likely to be used by sage grouse than the burned and untreated on average
Arkle and his colleagues found little sagebrush cover at burned sites whether treated or not.
because some sites burned 20 years ago and still haven't recovered said Arkle. We did not see a trend of increasing sagebrush cover with time
if just 2. 5%of the land is developed within five kilometers of a site the birds will be half as likely to use it.
The outlier ESR sites preferred by sage grouse had healthier sagebrush and shared common climate and post-treatment weather conditions.
Some sites are more resilient than others. It's possible that parts of the Great Basin will cross a tipping point of climate and species representation from
There is potential for sites to move into a new plant community state said Arkle. It's possible that some have gone past a threshold.

#Allergy tablet approval warrants caution for somea pill a day keeps spring allergies away. In a perfect world it would be that easy.
And for those suffering from an allergy to some grasses the Food and Drug Administration's (FDA) approval of the oral dissolvable tablets designed to help treat symptoms may be beneficial.

if tablets could be customized like allergy shots but that's not on the horizon yet said Dr. Foggs.
Although the approved tablets are beneficial only for those suffering from some forms of grass allergy the FDA's approval will help open the door for others getting approved such as tablets for ragweed and dust mite allergy.

To arrive at those conclusions the researchers used sediment cores from Lake Towuti an ancient lake on the island of Sulawesi in central Indonesia.

The cores showed an increase in abundance of grass in the same sediments that showed a decrease in surface runoff.
