Easily paralyzed flies provide clues to neurodegeneration
...tzky has been identifying, breeding and studying a raft
of fly mutants that, when exposed to minor temperature change, become completely paralyzed. The flies, which quickly recover when returned to room temperature, are now finding many uses in studies of human neurological disorders, drug discovery and i...
Multiphoton microscope observes cell membrane action

formation is not well understood. We hope our experiments -- based on 3-D-resolved multiphoton microscopy to illuminate membrane domains and transition behavior -- will encourage others to join in this study." Baumgart emphasizes that balloon animal...
