What challenges does globalization present for industrialized economies, such as the United States and the European Union? How will fluctuations in dollar and euro exchange rates affect economic growth, inflation and interest rates? Will globalization influence the role of the dollar and the euro in international financial systems? These are a few of the questions to be explored May 25 as high-ranking international finance policymakers from the European Union and the United States join scholars for a conference on “The Euro and the Dollar in a Globalized Economy” at Washington University in St. Louis.

Assab and Massawa, the two camels that produced antibodies for the caffeine testThree llamas and two camels have provided a way to tell whether your waiter swapped regular coffee for decaf in your after-dinner cup. Using the heat-resistant antibodies these camels and llamas make, researchers at the School of Medicine are developing a quick test for caffeine that works even with hot beverages. The researchers plan to adapt their technology to a simple test (“dipstick”) that can be used to check for caffeine in a variety of drinks.

Five undergraduates pursuing unpaid public-service internships will be the first beneficiaries of a new Public Service Summer Stipend program.

They are Alan Bender, Barbara Levy Landes, Sanford Loewentheil, Kate Hilliker Murashige and Jill Evans Petzall; John Berg will receive the Dean’s Medal.

Washington University in St. Louis will host a symposium May 30-31 to bring together people interested in developing new enterprises in Missouri based on research discoveries.

WarrenSpending by federal regulatory agencies is scheduled to decline when adjusted for inflation according to “Moderating Regulatory Growth: An Analysis of the U.S. Budget for Fiscal Years 2006 and 2007,” this year’s edition of the annual report on regulatory spending and staffing by the Mercatus Center at George Mason University and the Weidenbaum Center on the Economy, Government, and Public Policy at Washington University in St. Louis.

“U.S.-China Business Relations” is the focus of a three-day academic symposium that kicks off with a public conference from 7:30 a.m. to 3:30 p.m. May 11 in Room 311, Anheuser-Busch Hall. U.S.-China commercial relations and intellectual property rights are among topics to be covered.

Elvin-Lewis has written a chapter in a new book that is critical of the unregulated U.S. herbal trade.Ginsengs, echinaceas, and ephedras, oh my! These herbs sound innocuous enough, however, according to Memory Elvin-Lewis, Ph.D., professor of microbiology and ethnobotany in biomedicine in Arts & Sciences at Washington University in St. Louis, Americans are unaware of the dangers inherent in these herbal supplements.

Their findings advance the understanding of photosynthesis.In the famous Robert Frost poem, “The Road Not Taken,” the persona, forced to travel one of two roads, takes the one less traveled by, and “that has made all the difference.” Chemists at Washington University in St. Louis and Stanford University, in kinship with Frost, have modified a key protein in a bacterium to move electrons along a pathway not normally traveled by. They got this to happen 70 percent of the time. That yield “makes all the difference.” More…

Olga Pontes & Craig PikaardThe protein HDA6 shows up as a red stain in this Arabidopsis leaf cell nucleus.A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off — in this case, the turning off of thousands of nearly identical genes in a hybrid plant. Studying the phenomenon of nucleolar dominance, in which one parental set of ribosomal genes in a hybrid is silenced, Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and colleagues have identified the protein HDA6 as an important player in the silencing.
