“This provides confirmation of the potential benefits of plaque-clearing treatments and also gets us rethinking our theories,” says senior author David H. Holtzman. More medical news

He and his research team are developing an information-theoretic foundation for the design and analysis of imaging systems.

Designated a “Leadership in Energy and Environmental Design” structure, only one other in the St. Louis area has received this recognition.

John W. Bennett, Ph.D., founder and first chair of the Department of Anthropology in Arts & Sciences, died Feb. 1 at Alexian Brothers Landsdowne Village in St. Louis. He was 89.

Family structure may have an effect on educational outcomes.Educational outcomes of children in stable blended families are substantially worse than those of children reared in traditional nuclear families, according to a study published in the most recent issue of the journal Demography. Both stepchildren and their half-siblings who are the joint children of both parents achieved at similar levels, well below those of traditional nuclear families where all the children are the joint offspring of both parents, according to economists Donna Ginther of the University of Kansas and Robert Pollak of Washington University in St. Louis.

David Kilper / WUSTL PhotoWUSTL researchers are trying to infer the Egyptian climate from the fossil evidence.Earth and planetary scientists at Washington University in St. Louis are studying snail fossils to understand the climate of northern Africa 130,000 years ago. While that might sound a bit like relying on wooly bear caterpillars to predict the severity of winter, the snails actually reveal clues about the climate and environment of western Egypt, lo those many years ago. They also could shed light on the possible role weather and climate played in the dispersal of humans “out of Africa” and into Europe and Asia.

Carrine Blank/WUSTL PhotoA WUSTL scientist suggests that Cyanobacteria arose in freshwater environments rather than in the sea.A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth’s development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University assistant professor of geomicrobiology in the Department of Earth & Planetary Sciences in Arts & Sciences, studying Cyanobacteria – bacteria that use light, water, and carbon dioxide to produce oxygen and biomass – has concluded that these species got their start on Earth in freshwater systems on continents and gradually evolved to exist in brackish water environments, then higher salt ones, marine and hyper saline (salt crust) environments.

Thomas J. Hund, Ph.D., post-doctoral researcher in Pathology ( in Dr. Jeffrey Saffitz laboratory) at the Washington University School of Medicine, and Yoram Rudy, The Fred Saigh Distinguished Professor of Engineering at Washington University, have incorporated the Calcium/Calmodulin-dependent Protein Kinase II (CaMKII) regulatory pathway into their model, improving the understanding of the relationship between calcium handling in cardiac cells and the cell’s electrical activity.

Streams of junk mail with personalized offers for a myriad of services seem never-ending. While annoying, these solicitations raise significant privacy concerns about how these companies know so much about the recipient’s life. Many legislators and legal experts shy away from legislation that would protect the privacy of American’s personal information claiming that such rules would violate the First Amendment. But Neil M. Richards, noted privacy law expert and associate professor of law at Washington University in St. Louis, denies such assumptions.
