Lihong Wang, Ph.D., became the first Gene K. Beare Distinguished Professor of Biomedical Engineering in a Nov. 29 ceremony.

Harvard physicist Lisa Randall explains how our visible world of four dimensions could be embedded in a higher-dimensional universe at the Assembly Series at 11 a.m. on Feb. 7 in Graham Chapel.

Michael Marrah and Bradley Castanho have been named assistant vice chancellors for research and co-directors of the Office of Technology Management (OTM) at Washington University. Together, they bring expertise in business, science and law to the OTM, which is charged with identifying University discoveries that have commercial potential and licensing them to private companies, where the technology can be developed for the benefit of the public.

Studying stars has never been so easy, thanks to Ernst K. Zinner, Ph.D., research professor of physics and of earth and planetary sciences, both in Arts & Sciences, at Washington University. For the past 30-plus years, Zinner has helped develop and fine-tune increasingly sophisticated instruments that allow researchers to get detailed information about circumstellar and interstellar dust — actual stardust — right in their own labs. These precision instruments use a measurement technique called secondary ion mass spectrometry (SIMS). To recognize Zinner’s important contributions to the development of SIMS and its many applications in the earth and space sciences, a scientific symposium will be held Feb. 3-4 in Crow Hall, Room 201.

Scientists at the School of Medicine in St. Louis and the biotech firm Nimblegen Systems Inc. have successfully tested a technique for identifying newly recognized DNA variations that may influence disease risk. Rather than focus on errors and alterations in DNA sequence, the new technique highlights variations in the number of copies of a particular gene.

Stardust, the NASA spacecraft mission, was given that name in hopes that the seven-year journey to capture comet samples would bring back to Earth, well, stardust. In an article in a special issue of the journal Science, Washington University researchers are the first to report that a sample they received from the mission actually does contain stardust — particles that are older than the sun.

VIDEO AVAILABLE: Stardust, the NASA spacecraft mission, was given that name in hopes that the seven-year journey to capture comet samples would bring back to Earth, well, stardust. In an article coming out in the Dec. 15, 2006, issue of the journal Science, researchers at Washington University in St. Louis are the first to report that a sample they received from the mission actually does contain stardust — particles that are older than the sun.

“I smell a rat!” Researchers have found that the sense of smelling in mice is affected by a biological clock devoted entirely to olfaction — smelling stuff, like sleeping and waking, is on a daily cycle.Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours. A team led by Erik Herzog, Ph.D., Washington University associate professor of Biology in Arts & Sciences, discovered the clock in the olfactory bulb, the brain center that aids the mouse in detecting odors.
