rix. Globally, basal myosin stress fibers organized perpendicular to the tissue anterior-posterior axis are especially strong at the middle band of the tissue. This global organized basal contracting machinery is responsible for the narrowing of the egg chamber width and thus the proper elongation of the tissue.

VIDEO PUBLIC OUTREACH:

Leonard Bosgraaf, Ph.D., Molecular Shots, Inc, of Groningen, The Netherlands, for "Firing Neurons," a movie created entirely by computer animation. It shows neurons firing action potentials and the waves of these signals going through the axon and synapses. The scale is about 20 pixels per micrometer in the first part of the movie. At the end of the movie, the camera zooms in all the way to protein level (about three pixels per nanometer).

2nd PLACE: VIDEO:
(Tie: 2 winners)

Karl Lechtreck, Ph.D., University of Massachusetts Medical School, Worcester, for "Motion of Epidymal Cilia," a high-speed video shot at the equivalent of 200 frames per second with differential interference contrast (DIC) microscopy. In exquisite slow motion (shown at 10 frames per second), the video reveals ciliary bending inside sections of mice trachea.

Rosalind Silverman, Ph.D., University of Toronto, for "Fifty Stars⎯Fifty Years," showing cycles of division of Drosophila embryos injected with GFP NLS (pseudo-colored). Once the nuclear membranes disassemble, the fluorescent signal dissipates to reorganize in the next cell cycle when the membrane reforms.

2nd PLACE: IMAGE:

Graham Johnson, graduate student at Scripps Research Institute in La Jolla, for "Promiscuous membrane drug transporters," which illustrates multi-drug resistance (MDR) transporters. MDRs exhibit poly-specific recognition, enabling numerous, chemically different compounds to pass through them. MDR transporters are studied to reveal a hypothesized mechanism-of-action and clues to how such a mecha
