From the Architectural Dynamics in Living Cells Program…
This spring and summer visitors to the Architectural Dynamics in Living Cells Program included: Jim LaFountain from the University at Buffalo; Issei Mabuchi, recipient of MBL’s 2003 Robert Day Allen Fellowship, from Tokyo University; Makoto Goda from Japan Biological Information Research Center in Tokyo; and Joseph Hoffman from Yale University.
Rudolf Oldenbourg is currently in Japan. He was invited to give a talk on “Dynamic views of living cell fine structure revealed by electro-optically modulated polarization microscopy” at the Symposium on Nano Biotechnology in Sendai sponsored by the Society of Chemical Engineering and the Bioimaging Society of Japan. Following the symposium he will visit with Yoshi Fujiyoshi at Kyoto University. Oldenbourg and Fujiyoshi are currently collaborating on a project funded by Japan Science and Technology Corporation (JST). As part of this collaboration, postdoc Yuki Kagawa will be joining the Architectural Dynamics in Living Cells Program here in Woods Hole in October. Kagawa received his Ph.D. in Bioscience from Tokyo Institute of Technology and is currently a lecturer at the Nippon Engineering College in Tokyo, Japan.
In August, Michael Shribak attended the conference on “Microscopy and Microanalysis 2003” in San Antonio, Texas, to report on the success that he and Oldenbourg have had in developing a polarized light microscope for imaging birefringent objects whose optic axis is inclined away from the focal plane, and for measuring the inclination angle and principal retardance of the object, which is achieved by scanned aperture polarized light microscopy.
Jim Valles of the Physics Department at Brown University is spending his sabbatical at the MBL from September 2003 to January 2004. Jim’s work in solid state physics lead him to explore the effect of high, steady magnetic fields on cell division and early embryonic development. Jim has published articles on magnetic levitation of biological materials and magnetically induced reorientation of cell cleavage. He is looking forward to collaborating with members of the Architectural Dynamics in Living Cells Program and other interested parties to learn about cell biology and optical imaging methods.

Elizabeth Neeley, a first-year BUMP Ph.D. student, recently won the Stoye Award for best student oral presentation at the annual meeting of the American Society of Ichthyologists and Herpetologists for her talk, “Trends in color patterns among neotropical wrasses.” This award is typically won by students presenting their final dissertation research.
