Arvidson, Ph.D., the WUSTL chair of earth and planetary sciences, a computer specialist and four WUSTL students. Their goal is to infer from images and other data the geological history of the landing site and to imply some theories about current and past climate on Mars. Will they find ice?

Douglas A. Wiens, Ph.D., professor of earth and planetary sciences in Arts & Sciences, and colleagues combined seismological and global positioning system (GPS) analyses to reveal two bursts of seismic waves from an ice stream in Antarctica every day, each one equivalent to a magnitude seven earthquake.

Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery.

QuatranoRalph S. Quatrano, Ph.D., the Spencer T. Olin Professor and chair of the Washington University Department of Biology, has been named interim dean of the faculty of Arts & Sciences effective July 1, 2008, according to Chancellor Mark S. Wrighton. He succeeds Executive Vice Chancellor Edward S. Macias, Ph.D., dean of Arts & Sciences and the Barbara and David Thomas Distinguished Professor in Arts & Sciences.

Researchers at Washington University in St. Louis have gained the first detailed insight into the way circadian rhythms govern global gene expression in Cyanothece, a type of cyanobacterium (blue-green algae) known to cycle between photosynthesis during the day and nitrogen fixation at night.

Washington University’s Division of Biology and Biomedical Sciences (DBBS) celebrated two milestones May 1-2: its 35th anniversary and the graduation of its 1,000th student. The Division spans both the University’s Danforth and Medical campuses to provide Ph.D. training programs in biology and the biomedical sciences. Established in 1973, the Division has become the national model for graduate education in biology and biomedical sciences because of its collaborative, interdisciplinary approach.

School of Medicine researchers have used nanotechology to focus a much lower drug dose to slow tumor growth in rabbits.

They are studying ways to take “the smell of money,” as farmers long have termed manure’s odor, and produce biogas from it.

Nanoparticles (yellow) show that a treated tumor (left) has less blood vessel growth than an untreated tumor.Anyone facing chemotherapy would welcome an advance promising to dramatically reduce their dose of these often harsh drugs. Using nanotechnology, researchers at the School of Medicine have taken a step closer to that goal. The researchers focused a powerful drug directly on tumors in rabbits using drug-coated nanoparticles.
