This Week in Cell

In the current issue of Cell, German researchers outline the strategy that they used to find hundreds of genes involved in hearing in fruit flies. By comparing gene expression patterns in sections of sound-sensing antenna in flies with or without an organ in that antenna that's needed to transmit sound, the team found 274 Drosophila genes contributing to auditory organ function. While four of these had been linked to hearing in the fruit fly model organism previously, they note, the rest are new.
