David Kilper/WUSTL PhotoKaren L. Wooley and lab members examine polymer samples.A chemist at Washington University in St. Louis has developed a remarkable nanostructured material that can repel pests, sweeten the air, and some day might even be used as a timed drug delivery system — as a nasal spray, for instance. Karen L. Wooley, Ph.D., Washington University James S. McDonnell Distinguished University Professor in Arts & Sciences, has taken the same materials that she developed more than four years ago as marine “antifouling” coatings that inhibit marine organisms such as barnacles from attaching to the hull of ships to now capture fragrance molecules and release them at room temperature.

Temperature is rising as St. Louis tackles the ramifications of a flu epidemic.St. Louis is one of the few cities trying to stay ahead of the pandemic curve, thanks to workshops being conducted this spring and summer that bring together area institutions and businesses in round table formats. The Business Community and Pandemic Flu Roundtable is sponsored by the Washington University School of Engineering and Applied Science’s Center for the Application of Information Technology (CAIT) and the University’s School of Medicine. CAIT is St. Louis’ center for IT training, professional development, and executive interaction for more than 25 years. More than 100 business and institutional attendees are learning to address everything from potential vaccines and medications to sick leave policy and protective gear. More…

With commonly available treatment strategies, 90 percent of women with recurrent cervical cancer die within five years. So physicians are understandably eager to uncover more effective drug therapies, and researchers at the School of Medicine have now obtained encouraging results by combining a traditional cell-killing agent with Avastin, a recently developed inhibitor of blood-vessel growth.

These brain images point out the areas most consistently active during a variety of cognitive tasks.Scientists have used data from scans of 183 subjects to identify brain areas that consistently become active in a variety of cognitive tasks, such as reading, learning a rhythm or analyzing a picture. If the brain in action can be compared to a symphony, with specialized sections required to pitch in at the right time to produce the desired melody, then the regions highlighted by the new study may be likened to conductors, researchers at the School of Medicine assert.

Matt Blunt addressed a group of several hundred local science, business and academic leaders at WUSTL’s 21st Century Science: Foundation for Innovation symposium May 31 at the Eric P. Newman Education Center on the School of Medicine campus. Hear the Governor’s speech in its entirety, as well as Chancellor Mark Wrighton’s closing remarks.

Investigators at the School of Medicine have found that eating a low-calorie yet nutritionally balanced diet lowers concentrations of a thyroid hormone called triiodothyronine (T3), which controls the body’s energy balance and cellular metabolism.

After preliminary success using artificial bone to replace degenerative spinal disks in the neck and lower back, neurosurgeons at the School of Medicine and Barnes-Jewish Hospital are preparing a study to formally compare the performance of the synthetic material against that of real bone.

Despite lack of a key component of the immune system, a line of genetically engineered mice can control chronic herpes virus infections, researchers at the School of Medicine have found. Scientists suspect the missing component has a previously unrecognized backup that fills the void left by its absence. If so, that backup may become a new focus for efforts to design antiviral vaccines.
