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.

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.”

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.

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. 

At the bottom of plants’ ability to sense touch, gravity or the proximity of a nearby trellis are mechanosensitive channels, pores through the cells’ plasma membrane that are opened and closed by the deformation of the membrane. Elizabeth Haswell, PhD, a biologist at Washington University in St. Louis, is studying the roles these channels play in Arabidopsis plants by growing mutant plants that lack one or more of the 10 possible channel proteins in this species.

WUSTL geophysicist Michael Wysession is leading a team of scholars who are helping the nation’s top science agencies develop national standards for K-12 science education. The core disciplines covered by the new standards include engineering and Earth and planetary sciences, which have never before been a standard part of the K-12 curriculum. Wysession currently co-leads the team writing the Earth and planetary standards, and a key focus of his mission is ensuring that students gain a solid grasp of the Anthropocene, loosely defined as the period in Earth’s history during which human activities have had a significant impact on Earth systems.
