Science & Technology

Stephen F. & Camilla T. Brauer Hall, a new engineering building at the northeast corner of the Danforth Campus of Washington University in St. Louis, was recently honored with a Project Achievement Award by the Construction Management Association of America (CMAA). But the CMAA award is only the latest of seven honors garnered by Brauer Hall, home to the School of Engineering & Applied Science’s Department of Energy, Environmental & Chemical Engineering.

At WUSTL’s Photosynthetic Antenna Research Center scientists have succeeded in making a light-harvesting antenna from scratch. The new antenna, modeled on the chlorosome found in green bacteria, is a giant assembly of pigment molecules. Chlorosomes allow green bacteria to photosynthesize even in the dim light in ocean deeps. The new technology may one day transform solar-powered devices.

Peter Wyse Jackson, PhD, was installed as the George Engelmann Professor of Botany in Arts & Sciences at Washington University in St. Louis in a ceremony held in Holmes Lounge, Ridgley Hall, Nov. 21. Wyse Jackson became president of the Missouri Botanical Garden in September 2010 and, by tradition, the president of the garden is also awarded the professorship at WUSTL

Traditionally, fossil-hunters often could only make educated guesses as to where fossils lie. The rest lay with chance. But thanks to a software model used by WUSTL professor Glenn Conroy, PhD, and researchers at Western Michigan University, fossil-hunters’ reliance on luck when finding fossils may be diminishing. Using artificial neural networks, Conroy and colleagues developed a computer model that can pinpoint productive fossil sites.  

Undergraduate students were in St. Louis Nov. 9-12 for the Annual Biomedical Research Conference for Minority Students, designed to encourage undergraduate, post baccalaureate and graduate underrepresented minority students to pursue advanced training in the biomedical and behavioral sciences. Washington University, under the leadership of the Division of Biology and Biomedical Sciences, hosted a visit the Danforth and Medical campuses for about 200 students.

Last January two amateur meteorite hunters dropped by Randy Korotev’s office at Washington University in St. Louis to show him their latest purchase, a 17-kilogram pallasite meteorite found in 2006 near Conception Junction (population 202) in northwest Missouri.Korotev, an expert in lunar meteorites, identified the stone as a piece of an asteroid. His lab also analyzed crystals within the rock to help identify its body of origin, eventually referring the meteorite hunters to UCLA for analysis of the metal in which the crystals are embedded.

Two engineering faculty have been chosen for I-CARES career development awards: John Fortner, PhD, and Brent Williams, PhD, both assistant professors in the Department of Energy, Environmental & Chemical Engineering. I-CARES, the International Center for Advanced Renewable Energy and Sustainability, was established in 2007 to encourage interdisciplinary research on problems in the fields of energy, environment and sustainability.

Yinjie Tang, PhD, the Francis Ahmann Career Development Assistant Professor in energy, environmental & chemical science, has won funding from the Bill & Melinda Gates Foundation to pursue an innovative global health research project, titled “Using fecal sludge for butanol fermentation.”

Richard L. Axelbaum, PhD, professor of energy, environmental & chemical engineering in the School of Engineering & Applied Science, is the new Stifel & Quinette Jens Professor in Environmental Engineering Science. Chancellor Mark S. Wrighton installed him in a ceremony Oct. 31 in Brauer Hall.

The timing, process and archaeology of the peopling of Europe by early modern humans have been actively debated for more than a century. Reassessment of the anatomy and dating of a fragmentary upper jaw with three teeth from Kent’s Cavern in southern England has shed new light on these issues.
