William C. “Billy” Kaufmann, a multimedia specialist in Medical Computing Services at the School of Medicine, died Monday, May 14, 2007, in a motorcycle accident in south St. Louis.

The School of Medicine is launching the center for Women’s Infectious Disease Research, a new effort to study infectious diseases that preferentially affect women.

A $2.5 million grant will continue the University’s work with local AIDS service organizations and with local health departments to encourage HIV testing.

Scientists probing the details of viral infection have discovered an intriguing surprise: in mice, herpes viruses hijack their host cells’ tools for fixing DNA damage and use those tools to enhance their own reproduction.

The list of reasons you shouldn’t smoke has gotten longer. Researchers at Washington University School of Medicine in St. Louis are reporting that smoking interferes with ligament healing. Each year in the United States there are more than 20 million reported ligament injuries, and MCL injuries—which affect a ligament supporting the knee joint—are the most common. Studying mice with MCL injuries, the team discovered cigarette smoking impairs the recruitment of cells to the injury site and delays healing following ligament repair surgery.

An X-ray of a case of scoliosis.Physicians have recognized scoliosis, the abnormal curvature of the spine, since the time of Hippocrates, but its causes have remained a mystery — until now. Researchers at Washington University School of Medicine in St. Louis and collaborating institutions have discovered a gene that underlies the condition, which affects about three percent of all children. The finding lays the groundwork for determining how the genetic defect leads to the C- and S-shaped curves that characterize scoliosis.

HamvasAaron Hamvas, M.D., a renowned pediatrician in newborn medicine and a leading authority on a lethal infant lung disease, has been appointed the first James P. Keating, M.D., Professor of Pediatrics at the School of Medicine. Hamvas is medical director of the Neonatal Intensive Care Unit at St. Louis Children’s Hospital and of Nursery Services at Barnes-Jewish Hospital.

Scientists revealed in November 2006 that stress increases production in mice of a brain peptide critical to Alzheimer’s disease. Now the same group has shown that blocking a different brain peptide slows the stress-induced increase, opening a new door to treatment. Researchers from the School of Medicine report the results online this week in the Proceedings of the National Academy of Sciences.

Washington University in St. Louis is creating a new International Center for Advanced Renewable Energy and Sustainability (I-CARES) to encourage and coordinate university-wide and external collaborative research in the areas of renewable energy and sustainability — including biofuels, CO2 mitigation and coal-related issues. The university will invest more than $55 million in the initiative, according to Chancellor Mark S. Wrighton.
