Henning and D1 Oils; www.jatropha.orgJatropha plantsDuring a practicum for the World Agricultural Forum, Washington University M.B.A. students realized that using ethanol as an alternative fuel in developing countries isn’t cost effective. Instead, they stumbled upon the jatropha plant, a hardy shrub with seeds that can easily produce oil to power basic generators. The students’ work demonstrated the potential for economic stability that jatropha could offer small villages. More…

More human-Neandertal mixing evidence uncovered

Erik Trinkaus, Ph.D., the Mary Tileston Hemenway Professor in Arts & Sciences at Washington University in St. Louis, and colleagues radiocarbon dated and analyzed the shapes of human bones from Romania’s Pestera Muierii (Cave of the Old Woman). The fossils, which were discovered in 1952, add to the small number of early modern human remains from Europe known to be more than 28,000 years old. More…

Football coach solicits words of wisdom from famous, successful people to motivate his team

Photo by Chris MitchellAbove is a selection of letters football coach Larry Kindbom has collected for his student-athletes since 1998 and self-published in his “Playbook of Champions.”Instead of getting his team fired up with movies or fire and brimstone, Larry Kindbom, football coach at Washington University in St. Louis, solicits motivational letters from successful people in all walks of life. He has received responses from people such as former U.S. Sen. Bob Dole, Vice President Al Gore, Southwest Airlines CEO Herb Kelleher, sportscaster Bob Costas and a host of other notables. This year, Kindbom’s taken the responses and self-published a book, “Playbook of Champions,” for his student-athletes. More…

Lewis and Clark data show narrower, more flood-prone River

Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences, has analyzed data from the Lewis and Clark expedition and says it shows that the Missouri River today is but a shadow of what it was two hundred years ago, narrower and more prone to serious flooding.A geologist at Washington University in St. Louis and his collaborator at Oxford University have interpreted data that Lewis and Clark collected during their famous expedition and found that the Missouri River has markedly narrowed and its water levels have become more variable over the past two hundred years. This narrowing, or channeling, created by wing dikes and levees constructed mainly in the 20th century, has put the Missouri River at an increased risk of more damaging floods, the authors say. They blame the fact that the river cannot spread out as it did naturally at the turn of the 19th century, thus forcing water levels higher. More…

NSAID increases liver damage in mice carrying mutant human gene

The large globules in the liver cells on the left are characteristic of alpha-1-antitrypsin deficiency. The image on the right shows normal liver cells.Research performed at Washington University School of Medicine in St. Louis sheds light on the mechanisms that contribute to liver disease in alpha-1-AT deficiency patients. People with alpha-1-deficiency have a genetic mutation that can lead to emphysema at an early age and to liver damage. Using an experimental mouse model of the disorder, the researchers investigated the effects of a non-steroidal anti-inflammatory drug (NSAID) on liver injury.

Surgical biopsy may reveal cancer in women with rare but benign breast condition

On a mammogram, LCIS and ALH typically look like small deposits of calcium.In women whose initial breast biopsies revealed certain rare, yet benign breast conditions, more extensive follow-up surgical biopsies found that up to 25% of them actually had cancer in addition to these benign lesions. Most of the cancers were invasive, meaning the tumors had penetrated normal breast tissue and would require treatment. In the study, conducted at Washington University School of Medicine in St. Louis, the women’s initial biopsies had revealed atypical lobular hyperplasia (ALH) or lobular carcinoma-in-situ (LCIS), conditions that increase the risk of breast cancer, but which are themselves considered benign.

Researchers study reimbursing living organ donors for out-of-pocket expenses

More than 80,000 people in the United States are on waiting lists for organ transplants. Some will have to wait for the death of a matching donor, but more and more people are receiving organs from living donors. In an effort to close the gap between organ supply and demand, researchers at Washington University School of Medicine, the University of Michigan and the American Society of Transplant Surgeons are studying ways to reimburse living donors for some of their out-of-pocket expenses when they choose to donate an organ.
