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.

Steven G. Krantz, Ph.D., professor of mathematics at Washington University in St. Louis, illuminates mathematicians’ very human brilliance in his book, Mathematical Apocrypha Redux, his sequel to his successful, original Mathematical Apocrypha, published in 2002, both by the Mathematical Association of America. The book is a collection of anecdotes about famous mathematicians and their frivolity, wisdom and situations, revealing more vulnerable, human versions of the remote and often eccentric savants.

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…

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.

Assab and Massawa, the two camels that produced antibodies for the caffeine testThree llamas and two camels have provided a way to tell whether your waiter swapped regular coffee for decaf in your after-dinner cup. Using the heat-resistant antibodies these camels and llamas make, researchers at the School of Medicine are developing a quick test for caffeine that works even with hot beverages. The researchers plan to adapt their technology to a simple test (“dipstick”) that can be used to check for caffeine in a variety of drinks.

Washington University in St. Louis will host a symposium May 30-31 to bring together people interested in developing new enterprises in Missouri based on research discoveries.

Robert Morley & Ed Richter investigated static electricity buildup from sliding down a plastic slide, which can temporarily silence the world to cochlear implantees.

Olga Pontes & Craig PikaardThe protein HDA6 shows up as a red stain in this Arabidopsis leaf cell nucleus.A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off — in this case, the turning off of thousands of nearly identical genes in a hybrid plant. Studying the phenomenon of nucleolar dominance, in which one parental set of ribosomal genes in a hybrid is silenced, Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and colleagues have identified the protein HDA6 as an important player in the silencing.

Elvin-Lewis has written a chapter in a new book that is critical of the unregulated U.S. herbal trade.Ginsengs, echinaceas, and ephedras, oh my! These herbs sound innocuous enough, however, according to Memory Elvin-Lewis, Ph.D., professor of microbiology and ethnobotany in biomedicine in Arts & Sciences at Washington University in St. Louis, Americans are unaware of the dangers inherent in these herbal supplements.

Static electricity buildup from sliding down a plastic slide — instant summertime fun for those with normal hearing — can temporarily silence the world to cochlear implantees. Two electrical engineers at Washington University in St. Louis tested static electricity buildup — which can zap a cochlear implant — on sliding children to quantify the sparks. Thanks to some publicity and increased awareness, their research has inspired the St. Louis County Parks and Recreation Department to consider the problem, and an anti-static coating company to try to solve it.
