A hemispherewide phenomenon – and not just regional forces – has caused record-breaking amounts of freshwater to accumulate in the Arctic’s Beaufort Sea.

Frigid freshwater flowing into the Arctic Ocean from three of Russia’s mighty rivers was diverted hundreds of miles to a completely different part of the ocean in response to a decades-long shift in atmospheric pressure associated with the phenomenon called the Arctic Oscillation, according to findings published in the Jan. 5 issue of Nature.

*Commercial production will allow scientists, academia opportunity for use in cancer studies*

COLUMBIA, Mo. – Early detection of melanoma, the most aggressive skin cancer, is critical because melanoma will spread rapidly throughout the body. Now, University of Missouri researchers are one step closer to melanoma cancer detection at the cellular level, long before tumors have a chance to form. Commercial production of a device that measures melanoma using photoacoustics, or laser-induced ultrasound, will soon be available to scientists and academia for cancer studies. The commercial device also will be tested in clinical trials to provide the data required to obtain U.S. Food and Drug Administration approval for early diagnosis of metastatic melanoma and other cancers.

*Berkeley Lab scientists help verify science behind geologic carbon sequestration*

A demonstration project on the southeastern tip of Australia has helped to verify that depleted natural gas reservoirs can be repurposed for geologic carbon sequestration, which is a climate change mitigation strategy that involves pumping CO₂ deep underground for permanent storage.

The project, which includes scientists from Lawrence Berkeley National Laboratory (Berkeley Lab), also demonstrated that depleted gas fields have enough CO₂ storage capacity to make a significant contribution to reducing global emissions. (more…)

To Turn Up The Heat in Chilies, Just Add Water

Biologists have learned in recent years that wild chilies develop their trademark pungency, or heat, as a defense against a fungus that could destroy their seeds. But that doesn’t explain why some chilies are hot and others are not.

New research provides an answer: Hot chilies growing in dry areas need more water to produce as many seeds as non-pungent plants, but the Fusarium fungus is less of a threat in dryer environments so chilies in those areas are less likely to turn up the heat. In wetter regions, where Fusarium thrives, wild chilies build up their reserves of spicy capsaicin in self-defense. (more…)

A Bar, an Idea, and a Garage: The Story of CodeFlow

*Clark Roberts and Mike Cook dreamed up a better way to do code reviews one night in a bar. Today their side project, CodeFlow, is used by every division at Microsoft and will ship in the next version of Microsoft Visual Studio.*

REDMOND, Wash. — Jan. 5, 2012 — Two Microsoft developers walk into a bar, order $2 Pabst Blue Ribbon tall boys, and talk code.

Similar scenes probably play out every evening in Seattle, so there was nothing remarkable about the night in January 2009 when Clark Roberts and Mike Cook met up at Sully’s Bar. But most happy hours don’t spark a project that’s used by developers in every division at Microsoft and will ship in one of the company’s major products. This one did. (more…)

Bringing Passito to America

EAST LANSING, Mich. — A Michigan State University researcher is working with vintners to introduce passito, an age-old Italian wine to the United States.

Passito, traced to 800 B.C. in Italy, is also known as straw wine. The grapes for passito are typically hand-picked and allowed to dry on cellar racks or, more traditionally, on mats of straw. (more…)

Investment Risk Tolerance Affected by Age, Economic Climate, MU Study Shows

COLUMBIA, Mo. – As the U.S. economy continues to lag, many investors remain wary about taking risks with the stock market. Now, researchers at the University of Missouri have concluded that this attitude toward investment risk-taking is influenced by the age of the investor and the economic climate of the time period. Rui Yao, an assistant professor of personal financial planning in the College of Human Environmental Sciences at MU, found that willingness to take financial risks, or “risk tolerance,” decreases as investors age.

“Age has a pragmatic relationship with financial risk,” Yao said. “Each additional year of life represents a shortened time horizon for recouping market losses. In addition, individuals approaching or in retirement may shift focus from asset accumulation to asset preservation. These individuals may become relatively more concerned about potential loss of money when they are closer to retirement or no longer have a steady source of income.” (more…)

Upper Atmosphere Facilitates Changes That Let Mercury Enter Food Chain

Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere.

New research shows that the upper troposphere and lower stratosphere work to transform elemental mercury into oxidized mercury, which can easily be deposited into aquatic ecosystems and ultimately enter the food chain. (more…)
