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.

Jeffrey MarlowJeffrey J. Marlow, a senior in Arts & Sciences at Washington University in St. Louis, is one of 20 students nationwide named to the 2007 All-USA College Academic First Team, USA Today’s recognition program for outstanding undergraduates. Two other Washington University students were named to the third team and one student received honorable mention, resulting in Washington University tying with the University of Alabama for the most students selected in the newspaper’s competition.

A.G. Edwards Inc., the St. Louis-based national investment firm, will establish the A.G. Edwards Visiting Professorship in Entrepreneurship.

Eric ChouTesting the wake-sleep cycleA biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily.

Eric ChouA slice through the earth, showing the attenuation anomalies within the mantle.A seismologist at Washington University in St. Louis has made the first 3-D model of seismic wave damping — diminishing — deep in the Earth’s mantle and has revealed the existence of an underground water reservoir at least the volume of the Arctic Ocean. The research, which analyzed 80,000 shear waves from more than 600,000 seismograms, provides the first evidence for water existing in the Earth’s deep mantle.

Lihong Wang, Ph.D., became the first Gene K. Beare Distinguished Professor of Biomedical Engineering in a Nov. 29 ceremony.

“I smell a rat!” Researchers have found that the sense of smelling in mice is affected by a biological clock devoted entirely to olfaction — smelling stuff, like sleeping and waking, is on a daily cycle.Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours. A team led by Erik Herzog, Ph.D., Washington University associate professor of Biology in Arts & Sciences, discovered the clock in the olfactory bulb, the brain center that aids the mouse in detecting odors.
