Moonwalker Flies Backing Up

The team of Barry Dickson, former scientific director of the IMP, managed to isolate “moonwalker flies” in a high-throughput screen. Screening a large collection of fruit flies, the scientists found specimens that seemed locked in reverse gear. Dickson and his co-workers were able to trace these changes in walking direction back to the activity of specific neurons in the brain. The results of the study will be published in the current issue of Science.
