Through a $631,000 grant from the National Science Foundation’s Robert Noyce Master Teacher Scholarship Program, WUSTL’s Phyllis Balcerzak guides a group of local educators who study teacher leadership. The Noyce fellows collaborate with Balcerzak and other WUSTL faculty monthly. They develop leadership projects through professional organizations and other local school districts. Teachers accepted to the program have master’s degrees and several years of experience. They also receive a stipend for the three-year program.

Scientists once thought the fertilization effect of rising carbon dioxide concentrations would offset factors such as higher temperatures or drier soils that would reduce crops yields. This view is turning out to be overly optimistic. A new study shows that soybeans switch into unproductive metabolic activity at higher carbon dioxide concentrations. The invasive cheatgrass, on the other hand, has no switch, or control, and continues to efficiently transport water and assimilate carbon. Crop plants might need to be equipped with similar traits to survive future arid high-carbon dioxide environments.

A seven-year experiment shows that pond communities bear the imprint of random events in their past, such as the order in which species were introduced into the ponds. This finding locates one of the wellsprings of biodiversity but also suggests that it may not be possible to restore ecosystems whose history we cannot recreate.

The Howard Hughes Medical Institute has awarded Washington University  a 2010 Research University Grant to support the devleopment of creative, research-based courses and curricula. The university will receive $1.6 million over a period of four years/ HHMI also awarded Sarah C. R. Elgin, PhD, the Viktor Hamburger Professor of Arts and Sciences at Washington University in St. Louis, a long-time HHMI professor, $80,000 over four years to support her work on important problems facing science education. 

An archeologist at Washington University in St. Louis is helping to reveal for the first time a snapshot of rural life in China during the Han Dynasty. The rural farming village of Sanyangzhuang was flooded by silt-heavy water from the Yellow River around 2,000 year ago. Working with Chinese colleagues, T.R. Kidder, PhD, professor and chair of anthropology in Arts & Sciences, is working to excavate the site, which offers a exceptionally well-preserved view of daily life in Western China more than 2,000 years ago.

As part of the Human Microbiome Project (HMP), scientists at Washington University School of Medicine in St. Louis and their colleagues have decoded the genomes of 178 microbes from the human body, they report in the journal Science.

At last count there were three physics PhDs in Congress, five science PhDs total, and 228 senators and congressmen with law degrees. WUSTL postdoctoral fellow in physics Chris Spitzer, who has just been named a Congressional Science Fellow for 2010-2011, is off to Washington to learn and observe but also to do what he can to make sure national policy in areas such as energy and the environment reflects current scientific understanding.

The International Center for Advanced Renewable Energy and Sustainability (I-CARES) has awarded 11 faculty members — university professors undertaking innovative and collaborative research in the broad areas of bioenergy and sustainability — grants totaling nearly $300,000.

Sally Elgin wins award for her commitment to finding new, more powerful ways to teach science and to support teachers in the biological sciences.

The decoding  of the Neandertal genome, which suggested modern humans interbred with Neandertals, followed hard on the heals of a WUSTL professor’s critique on mathematical and logical grounds of a gene analysis that suggested no interbreeding.
