Science & Technology

At Washington University in St. Louis this semester, the Department of Physics and University College, both in Arts & Sciences, will describe a few great experiments in physics. Four lectures will be held at 10 a.m. on four consecutive Saturday mornings, March 10–31, in the Hughes Lecture Room, Room 201 in Crow Hall.

Washington University in St. Louis has joined a national experiment to develop a new generation of college science and engineering faculty, one equipped to excel in the classroom as well as the lab. Founded in 2003 at the University of Wisconsin-Madison, the Center for the Integration of Research, Teaching and Learning (CIRTL), the mission of the CIRTL network of 25 research universities  is to prepare science graduate students to be as bold and creative in the classroom as they are in their programs of research.

It’s no secret that battlefield trauma can leave veterans with deep emotional scars that impact their ability to function in civilian life. But new research from Washington University in St. Louis suggests that military service, even without combat, has a subtle lingering effect on a man’s personality, making it potentially more difficult for veterans to get along with friends, family and co-workers.

Frank Yin, PhD, ambassador to Tsinghua University, a partner institution in the McDonnell International Scholars Academy, invites Washington University in St. Louis faculty and students to participate in Tsinghua’s annual English summer camp, which will be held from June 26 to July 13, 2012. The English summer camp is an intensive English language experience for Tsinghua students. Each day is devoted to lessons, lectures, and various activities, including seminars, song and dance competitions, and other games. WUSTL native or near-native English speakers are invited to join the camp as visiting teachers and volunteers.

Frédéric Moynier, PhD, 33, assistant professor in the Department of Earth and Planetary Sciences in Arts & Sciences and a member of the McDonnell Center for the Space Sciences at Washington University in St. Louis, has been named the recipient of the 2012 Houtermans Award and the Nier Prize, both given for exceptional work by a scientist younger than 35.

The lab of Jospeh Jez, PhD, associate professor of biology in Arts & Sciences, crystallizes proteins so that people can see what they look like in three dimensions. But getting proteins to crystallize is difficult and involves an element of luck — so one of Jez’s main jobs is to be the lab’s unreasonable optimist.

A giant experiment is under way at the Tyson Research Center, Washington University in St. Louis’ 2,000-acre outdoor laboratory for ecosystem studies. The experiment, led by Tiffany Knight, PhD, associate professor of biology, will test three different variables in 32 glades with the goal of establishing best practices for restoring not just degraded glade habitats but degraded ecosystems in general. The experiment is expected to draw collaborating scientists locally and around the world.

False negatives and positives plague the reading of mammograms, limiting their usefulness. Cindy Grimm, a computer scientist at Washington University in St. Louis, and colleagues have shown the accuracy of novice readers can be improved by nudging them visually to follow the scanpath of an expert radiologist. The “nudge” is a brief change in the brightness or warmth in the image in the peripheral field of view.

The Presolar Grain Workshop that gathers scientists who study tiny bits of stars that were born and died billions of years ago — before the formation of the solar system — is returning to Washington University in St. Louis this year. Sessions begins at 8:30 a.m. Saturday, Jan. 28, and continue through the weekend in Crow and Compton halls. Attendees will include 45 astrophysicists from WUSTL’s Laboratory for Space Sciences and other research institutions in the United States as well as from Australia, Brazil and Italy.

NASA has announced that Raymond E. Arvidson, PhD, a planetary scientist at Washington University in St. Louis, has been selected to be a participating scientist on the Mars Science Laboratory, a mission to land and operate a rover named Curiosity on Mars. Arvidson proposed that he use the rover itself as a terramechanics instrument to learn about Martian soils. He will be using a simulation of the rover and of the Martian terrain to contribute to path planning for the rover and to look for crusted soils created by the modern Martian water cycle.
