Carrying backpacks the right wayAs parents and kids make their lists for the August back-to-school sales, one item to consider should be a backpack — on wheels, says Nancy J. Bloom, Ph.D., a physical therapy instructor at Washington University School of Medicine in St. Louis. Kids backs are primarily bearing the weight of their schoolbooks. Bloom says that because young bones are growing all the way through high school, heavy backpacks need to be a major concern. She notes that there are a few important things that kids can do to avoid injury, including carrying their backpacks over both shoulders to balance the load.

Lowry explores the dynamics behind efforts to restore rivers.As America celebrates the bicentennial of Lewis & Clark’s epic journey up the untamed Missouri River, the nation finds itself on the verge of a new era in modern river management, one in which proponents of environmental protection and ecosystem restoration stand on equal footing with those of the hydropower, barge and boating industries. In a new book, Dam Politics: Restoring American Rivers (Georgetown University Press, 2003), noted environmental politics expert William R. Lowry explores the dynamics behind recent efforts to restore American river systems to a more pristine state. The politics of river restoration run deep, and it is politics, argues Lowry, that will ultimately dictate the success or failure of future efforts to restore and preserve the nation’s riverways.

Sophisticated brain imaging reveals that several brain regions can become overactivated when people with Tourette Syndrome perform tasks related to memory.Neuroscience researchers at Washington University School of Medicine in St. Louis are studying the brains of patients with Tourette Syndrome (TS) to see whether they can use sophisticated imaging techniques to identify differences in the dopamine system of people with the tics that characterize TS. A team of researchers, led by Kevin J. Black, M.D., assistant professor of psychiatry, neurology and radiology at Washington University School of Medicine, is using PET imaging to see what the brain does in response to levodopa, a natural amino acid that has been used for many years to treat movement disorders, such as Parkinson’s disease. With PET imaging, the researchers can measure the boost in the brain’s dopamine levels in response to the drug both in people with Tourette Syndrome and in those who do not have tics. By identifying differences, they hope to isolate the causes of tics and to help people with TS control or eliminate them.

Illustration from a Hans Christian Andersen story.What is “children’s literature?” As we pause between the perfect, all-ages storms of Harry Potter and the Order of the Phoenix and the upcoming Lord of the Rings: Return of the King film adaptation, the answer seems less clear than ever. In the current issue of Belle Lettres, a bi-monthly publication of Washington University’s International Writers Center in Arts & Sciences, a culture critic and a director of teacher education explain that the genre, always hard to define, remains poorly understood and frequently underestimated.

Erik Trinkaus, professor of anthropology in Arts & Sciences, examines a Neandertal skull.New scientific evidence challenges a common perception that Neandertals — a close evolutionary relative to modern humans that lived 230,000 to 30,000 years ago — possessed exceptionally long faces. Instead, a report authored by Erik Trinkaus, Ph.D., the Mary Tileston Hemenway Professor of anthropology in Arts & Sciences at Washington University in St. Louis, shows that modern humans are really the “odd man out” when it comes to facial lengths, which drop off dramatically compared with their ancestral predecessors.

A team of researchers from Washington University School of Medicine in St. Louis, the Mayo Clinic in Rochester, Minn., the Harvard School of Public Health and several other clinical centers around the United States has found that treating depression and social isolation in recent heart attack patients does not reduce the risk of death or second heart attack. Results from the Enhancing Recovery in Coronary Heart Disease Patients Study (ENRICHD) are published in the June 18 issue of the Journal of the American Medical Association.

Nationally speaking, high school-level courses in graphic design, as opposed to general art or special projects such as yearbooks or student newspapers, are surprisingly rare. So when venerable University City High School, 7401 Balson Ave., launched a new graphics class last year, a group of visual communications majors from Washington University’s School of Art readily agreed to help tutor students in the fledgling program.

MoretonThe Federal Communications Commission (FCC) voted June 2 on the most significant overhaul of media ownership rules in decades, including a change that allows television networks to own more local stations. The new rule loosens the national television network ownership cap — raising the number of viewers the networks can reach to 45 percent from 35 percent of the nation’s viewers. Patrick Moreton, Ph.D., a professor of organization and strategy at the Olin School of Business at Washington University in St. Louis, says that the changes are in a very real sense, a “catch-up exercise,” forced on it by changes in the technology used to produce and deliver entertainment and news.

Albright, Ph.D., outlines her views on global policy issues.The United States could suffer long-term consequences if it is not careful about how it uses its strength, former Secretary of State Madeleine K. Albright said Friday at Washington University in St. Louis. “The extent of American power has created an opportunity for us to make our nation more secure within a world that is healthier, richer and more peaceful than it has ever been,” Albright said. “But if we are not prudent in exercising that power, we will create resentments that will make it much harder in the long run to achieve our goals.”

FergusonRoger W. Ferguson, Jr., Vice Chairman of the Board of Governors of the Federal Reserve System, gave the commencement address to M.B.A. and Ph.D. graduates of the Olin School of Business at Washington University in St. Louis on May 16. Dr. Ferguson became a Member of the Board of Governors in 1997 to fill an unexpired term and was reappointed in 2001 to a full term ending in 2014. The complete text of his commencement address to the Olin School of Business is available from the Federal Reserve System.
