Women from Mahabo Village in Madagascar weaving baskets for the Blessing Basket Project.It might seem odd that college students in the middle of the United States could make a difference to a small village in a developing country halfway around the world, but that’s exactly what happened when five students from Washington University in St. Louis went to Madagascar.

The Kemper Art Museum will present “Ansel Adams: Reverence for Life,” an exhibition of photographs showcasing works from the personal collections of the Adams family, in conjunction with the International Symposium on Energy and Environment, sponsored by the McDonnell International Scholars Academy.

David Kilper/WUSTL PhotoKevin Moeller’s group is pioneering new methods for building libraries of small molecules on addressable electrode arrays.A chemist at Washington University in St. Louis is making molecules the new-fashioned way — selectively harnessing thousands of minuscule electrodes on a tiny computer chip that do chemical reactions and yield molecules that bind to receptor sites. Kevin Moeller, Ph.D., Washington University professor of chemistry in Arts & Sciences, is doing this so that the electrodes on the chip can be used to monitor the biological behavior of up to 12,000 molecules at the same time.

Photosynthesis transforms light, carbon dioxide and water into chemical energy in plants and some bacteria.When it comes to studying energy transfer in photosynthesis, it’s good to think “outside the bun.” That’s what Robert Blankenship, Ph.D., professor of biology and chemistry in Arts & Sciences at Washington University in St. Louis, did when he contributed a protein that he calls the taco shell protein to a study performed by his collaborators at Lawrence Berkeley National Laboratory and the University of California at Berkeley. The protein enabled the surprising discovery of a quantum effect in photosynthesis.

David Kilper/WUSTL PhotoPratim Biswas and his group have developed a method to make a variety of oxide semiconductors that, when put into water promote chemical reactions that split water into hydrogen and oxygen.Engineers at Washington University in St. Louis have developed a unique photocatalytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The group is developing novel methodologies for synthesis of nanostructured films with superior opto-electronic properties.

The International Symposium on Energy and Environment, sponsored by the McDonnell International Scholars Academy, will bring prominent international university presidents to campus May 4-7, marking the first such gathering in the United States.

WUSTL engineers have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The technique will be demonstrated at a poster session May 6, 2007, at the International Symposium on Energy and Environment, held at the University.

*White House Ruin, Canyon de Chelly National Monument, AZ*Ansel Adams (1902-1984) is celebrated as one of the world’s foremost landscape photographers. In May, the Mildred Lane Kemper Art Museum at Washington University in St. Louis will present Ansel Adams: Reverence for Life, an exhibition of photographs showcasing works from the personal collections of the Adams family.

An earthquake engineer at Washington University in St. Louis has successfully performed the first test of wireless sensors in the simulated structural control of a model laboratory building. Shirley J. Dyke, Ph.D., the Edward C. Dicke Professor of Civil Engineering and director of the Washington University Structural Control and Earthquake Engineering Laboratory, combined the wireless sensors with special controls called magnetorheological dampers to limit damage from a simulated earthquake load.

Tabatha Heet, a junior earth and planetary sciences major and Pathfinder student, shows Ray Arvidson, earth and planetary sciences department chair, a potential landing site for the Phoenix mission to Mars.Earth and planetary scientists at Washington University in St. Louis are paving the way for a smooth landing on Mars for the Phoenix Mission scheduled to launch in August this year by making sure the set-down literally is not a rocky one. A team led by Raymond E. Arvidson, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, has been analyzing images taken from a NASA instrument to make sure that the Phoenix spacecraft lands in a spot on the Red planet’s northern plains that is relatively rock-free. Video included.
