On September 7 the Partnership for Undergraduate Life Sciences Education (PULSE) announced that Kathryn Miller, PhD, professor and chair of biology at Washington University in St. Louis has been selected as one of 40 Vision and Change Leadership Fellows. Over the next year the Vision and Change Leadership Fellows will consider and then recommend models for improving undergraduate life-sciences education.

The College of Arts & Sciences will introduce a newly revised curriculum, called Integrated InQuiry (IQ), for undergraduate students at Washington University in St. Louis. Developed over a four-year process with input from students, faculty and administrators, the IQ will be available to new undergraduates arriving this fall.

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

Sustainability is a complicated and pressing topic that spans many fields and has many implications — personal, social, national and global. The 2010 MLA Saturday Lecture Series, sponsored by the master of liberal arts program of University College in Arts & Sciences, will explore topics relating to sustainability, a key element in Washington University’s education and research agenda.

WUSTL geoarcheologist Jennifer Smith, Ph.D., is featured a History channel documentary that solves a series of geological mysteries about the Sahara’s past. The show, part of the “How the Earth Was Made” series, explains why there are marine fossils embedded in the blocks of stone from which the pyramids are made and drawings of people swimming are scratched into the walls of desert caves.
