*Joint BioEnergy Institute Researchers Identify Key Enzyme Structure*

The recent discovery that bisabolane, a member of the terpene class of chemical compounds used in fragrances and flavorings, holds high promise as a biosynthetic alternative to D2 diesel fuel has generated keen interest in the green energy community and the trucking industry. Now a second team of researchers with the U.S Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) has determined the three-dimensional crystal structure of a protein that is key to boosting the microbial-based production of bisabolane as an advanced biofuel.

The JBEI research team, led by bioengineers Paul Adams and Jay Keasling, solved the protein crystal structure of an enzyme in the Grand fir (Abies grandis) that synthesizes bisabolene, the immediate terpene precursor to bisabolane. The performance of this enzyme – the Abies grandis α-bisabolene synthase (AgBIS) – when engineered into microbes, has resulted in a bottleneck that hampers the conversion by the microbes of simple sugars into bisabolene.

MU Researchers Find Unique Protein Organization in Arteries Associated with Cardiovascular Disease

*Knowledge could assist in tissue replacements, treatments for high blood pressure and diabetes*

COLUMBIA, Mo. – Human arteries – some smaller than a strand of hair – stiffen as a person ages. This stiffening is a factor in cardiovascular disease, the leading cause of death in the United States, because it contributes to the circulatory complications in disorders such as high blood pressure and diabetes. University of Missouri researchers have now used advanced 3-D microscopic imaging technology to identify and monitor the proteins involved in this stiffening process. These findings could eventually help researchers and physicians understand and treat complications associated with cardiovascular disease. (more…)

‘Tiger Mothers’ Should Tame Parenting Approach

EAST LANSING, Mich. — The Eastern view of parenting, as defined by best-selling author and self-described “tiger mother” Amy Chua, is that children should be pushed to excel at all costs. Parents needn’t worry about their happiness, she argues, only their success.

But now a Michigan State University scholar is refuting that theory. (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…)

COLLEGE PARK, Md. – Over the past decade, attacks and plots by homegrown terrorists in the United States have increased, the work of extremists from across the political spectrum – roughly 40 percent of it by so-called ‘lone wolf,’ non-aligned actors – says an analysis by the National Consortium for the Study of Terrorism and Responses to Terrorism (START) based at the University of Maryland.

The statistics underscore the threat addressed in a White House plan released Thursday: Strategic Implementation Plan for Empowering Local Partners to Prevent Violent Extremism in the United States – a blueprint for “building community resilience against violent extremism.” (more…)

UCLA Study Finds U.S. Has More Elected, Appointed Asian American Officials Than Ever

More Asian Pacific Americans hold public office in the United States than at any other time in U.S. history, a sign of the community’s growing engagement with the political process, according to a newly released political almanac published by UCLA’s Asian American Studies Center.

The 14th edition of the National Asian Pacific American Political Almanac, first published in 1976, contains information on all 3,000 current elected and appointed officials. It also analyzes political trends and makes electoral projections of the nation’s 17 million Asian Pacific Americans. (more…)

New Projection Shows Global Food Demand Doubling by 2050

*Increasing yield in poorer countries could decrease adverse environmental effects*

Global food demand could double by 2050, according to a new projection reported this week in the journal Proceedings of the National Academy of Sciences (PNAS).

The analysis also shows that the world faces major environmental challenges unless agricultural practices change.

Scientists David Tilman and Jason Hill of the University of Minnesota (UMN) and colleagues found that producing the amount of food needed could significantly increase levels of carbon dioxide and nitrogen in the environment, and may cause the extinction of numerous species. (more…)

*A forgotten artist’s work can help us understand ourselves, says U graduate*

“I am a detective of sorts,” Annika Johnson says. “And I find clues in paintings, documents, and letters that tell me about who the artist was that made them and when, where, and why they made them.”

Johnson, who received her art history degree from the U this past May and is now applying to graduate schools across the country, did undergraduate research on Clara Mairs—a little known Minnesota artist from the depression era. Johnson describes Mairs’ work as “playful yet psychological, monumental yet humble” and says she not only helped activate the state’s modern and avant-garde art movements but also was central in the early development of arts education in St. Paul.
