Landscape in pine plantation forest.Researchers at Washington University in St. Louis, along with collaborators at three other universities, have discovered that the biodiversity in a patch of habitat can extend outside the borders of a protected area; this effect is magnified when corridors — skinny strips of land — connect the habitats. Their findings, reported in this week’s online issue of the Proceedings of the National Academy of Sciences, provide a strategy for managing nature preserves to maximize biodiversity in the small spaces that are already formally protected.

Inside of the diamond cellOf the 92 naturally occurring elements, add another to the list of those that are superconductors. James S. Schilling, Ph.D., professor of physics in Arts & Sciences at Washington University in St. Louis, and Mathew Debessai, Ph.D., — Schilling’s doctoral student at the time — discovered that europium becomes superconducting at 1.8 K (-456 °F) and 80 GPa (790,000 atmospheres) of pressure, making it the 53rd known elemental superconductor and the 23rd at high pressure.

Younan XiaMaterial scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two-to-five times more effective than commercial catalysts. The novel technique eventually will enable a cost effective fuel cell technology, which has been waiting in the wings for decades and should give a boost for cleaner use of fuels worldwide.

WUSTL computer engineers are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational platform and a medical imaging device that fits in the palm of a hand.

In the world of small things, shape, order and orientation are surprisingly important, according to findings from a new study by chemists at Washington University in St. Louis. Lev Gelb, WUSTL associate professor of chemistry, his graduate student Brian Barnes, and postdoctoral researcher Daniel Siderius, used computer simulations to study a very simple model of molecules on surfaces, which looks a lot like the computer game “Tetris.” They have found that the shapes in this model (and in the game) do a number of surprising things.

Washington University and the Donald Danforth Plant Science Center have received two awards totaling $35 million from the U.S. Department of Energy (DOE) to do research on novel energy initiatives. At $20 million, the Washington University research award is the largest ever received on the Danforth Campus. The $15 million for the Donald Danforth Plant Science Center is the largest the organization has ever received.

Researchers at Washington University School of Medicine in St. Louis are studying military-like techniques to detect and destroy deadly pathogens, including cancerous tumors. Nanoparticles, invisible to the human eye, operate much like a laser-guided missile within the body. They are able to locate and even deliver medication directly to diseased areas with great accuracy in the laboratory. The researchers will soon begin testing the nanoparticles in human clinical trials.

David Kilper/WUSTL PhotoComputer engineers at Washington University in St. Louis are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational platform and a medical imaging device that fits in the palm of a hand. William D. Richard, Ph.D., associate professor of computer science and engineering, and David Zar, research associate in computer science and engineering, have made commercial USB ultrasound probes compatible with Microsoft Windows mobile-based smartphones, thanks to a $100,000 grant Microsoft awarded the two in 2008.

William (Will) G. Donnelly, son of Terrence and Ruth Donnelly of St. Louis, Mo. (63139), recently was named the inaugural recipient of the Boeing/FIRST Scholarship at Washington University. A senior at Gateway Institute of Technology in St. Louis, Donnelly will enter the university’s School of Engineering & Applied Science as a freshman when the fall semester begins in August 2009.
