A team led by physicist Ken Kelton, PhD, is building an electrostatic levitation chamber that will be installed at the Spallation Neutron Source at the Oak Ridge National Laboratory. Kelton and his colleagues are particularly eager to see what the new instrument will tell them about glass transition, “the deepest and most interesting unsolved problem in solid-state research.”

As one of the “generic geologists” on a dig called the Dakhleh Oasis Project, Jennifer Smith, PhD, associate professor of earth and planetary sciences in Arts & Sciences, was asked to sample the alum from ancient mines and to determine whether it could be the source of the blue in the “blue painted pottery” found at sites dating from the New Kingdom.

Peter Wyse Jackson, PhD (left), who has been appointed to succeed Peter H. Raven, PhD, the Engelmann Professor of Botany, as president of the Missouri Botanical Garden, visited the Danforth Campus March 3 to meet biology department faculty and to deliver a seminar on international efforts to slow or halt the loss of biodiversity.

The Tyson Living Learning Center at Washington University in St. Louis has been called one of the greenest buildings in the U.S. Green technologies behind the building are the focus of a National Public Radio Science Friday news video and an NPR radio discussion broadcast live from St. Louis March 12.

Nanocages that efficiently convert light to heat are the basis for a targeted form of phototherapy that would destroy tumors without making cancer patients sick.

Washington University will host its fourth ExxonMobil Bernard Harris Summer Science Camp June 20-July 2 for more than 45 St. Louis-area disadvantaged middle schoolers. The camp is a free, two-week academic residential camp designed to boost middle school students’ skills in math and science and their interest in related careers as well as introduce them to college life. Applications are being accepted through April 2.

The School of Medicine has received a $14.3 million grant through the American Recovery and Reinvestment Act to expand its high-powered data center for genomics. The facility’s sophisticated computer networks store massive amounts of genomic data used to identify the genetic origins of cancer and other diseases.

The Earth and Planetary Remote Sensing Laboratory has received a grant of $1.8 million per year for the next five years to extend and improve the Geosciences Node of the Planetary Data System, a distributed data system that archives and distributes planetary data from space missions. 

A new test allows scientists to discover whether ticks are carrying disease-causing bacteria and which animals provided their last blood meal. Results suggest three emerging diseases in the St. Louis area are carried by lone star ticks feeding on record-high populations of white-tailed deer.

The gift of “seeing ourselves as others see us” comes in handy when judging how we’ve made a first impression. Yet many come away with little or no clue about how that first impression was perceived. A new study suggests confidence is a key indicator of how well we’ve assessed impressions left behind.
