Pupal fat body cells recruited to skin wounds

Pupal fat body cells are motile cells that are recruited to skin wounds. This movie shows one fat body cell approaching an epithelial wound and forming a tight bond with the wound gap until wound re-epithelialisation is complete. Other fat body cells appear later and are seen patrolling in the vicinity. Fat body cells are shown in green (c564-Gal4+UAS-GFP) and epithelial nuclei in red (Ubq>Histone-RFP). Projection and Z plane views are shown on the left and right, respectively. Elapsed time is in top right corner in hours:minutes:seconds. Scale bar, 20 μm

Reconstruction of Neurons from an Electron Microscopy Volume of the Entire Adult Fruit Fly Brain

The neural basis for behavior and decision-making is defined, in part, by the wiring diagram between neurons in the brain. Zheng, Lauritzen et al. present a whole-brain electron microscopy image dataset of an adult fruit (or vinegar) fly, Drosophila melanogaster, sufficient to trace the synaptic connectivity of any selected brain circuit in this genetic model organism. In the image, a reconstruction of neurons from the volume are colored according to their soma locations. Over 20 labs have collectively reconstructed ~7 meters of cable length, ~5% of total in brain.
