In a study published last week in the journal Cell, scientists searched through potential genes in the roundworm C. elegans in order to find a likely candidate involved in forgetting. They subsequently discovered a gene that produces a particular protein, called musashi, that was found to be critical for time-dependent memory loss. In a learning task investigating the movement of these animals in response to either attractant or repellant odorants, they found that the…
