Eric ChouTesting the wake-sleep cycleA biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily.

NASALet’s visit Europa!William B. McKinnon, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, says the space science community suffers from an embarrassment of riches when pondering which of Jupiter’s moons should be studied next, because they all differ in the way that they can reveal more about planets and how they behave. But he thinks it is Europa that clearly commands the most attention.

Eric ChouA slice through the earth, showing the attenuation anomalies within the mantle.A seismologist at Washington University in St. Louis has made the first 3-D model of seismic wave damping — diminishing — deep in the Earth’s mantle and has revealed the existence of an underground water reservoir at least the volume of the Arctic Ocean. The research, which analyzed 80,000 shear waves from more than 600,000 seismograms, provides the first evidence for water existing in the Earth’s deep mantle.

In 1973, while a doctoral student at Indiana University, Henry I. Schvey befriended the eminent Austrian expressionist painter Oskar Kokoschka (1886-1980). Now chair of Washington University’s Performing Arts Department in Arts & Sciences, Schvey has written “Kokoschka: A Love Story,” an original drama about the artist’s torrid affair with Alma Mahler (1879-1964), the beautiful widow of composer Gustav Mahler (1860-1911).

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.

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. To recognize Zinner’s important contributions to the earth and space sciences, a scientific symposium will be held Feb. 3-4 in Crow Hall, Room 201.

KWUR (90.3 FM), Washington University’s student-run radio station, will launch KWUR WEEK, a series of on-campus events, with a free concert by four of the Saint Louis Symphony Orchestra’s newest—and youngest—players. The program will include string quartets by Franz Joseph Haydn and Johannes Brahms.

The great novelist, Nurrudin Farah, will be on the Washington University campus Feb. 13 and 14 to speak on “Political Islam and Clan in Present-day Somalia” for the Assembly Series, and to present a reading/discussion of his works for the Department of English in Arts & Sciences. Both events are free and open to the public.

Diana MichenerDeborah EisenbergAcclaimed fiction writer Deborah Eisenberg, the visiting Fannie Hurst Professor of Creative Literature, will read from her work Feb. 8 and host a Q&A session Feb. 15. Eisenberg is the author of five short story collections, most recently Twilight of the Super Heroes: Stories (2006).

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.
