Researchers at SUNY Downstate Medical Center have apparently been tinkering with selectively erasing the memories of rats with a mysterious drug they call ZIP. In the trial, mice who had learned to avoid an electrified area of their cage, once injected with ZIP, appeared to have forgotten about the electrification, and ceased to avoid the area. They have also successfully made the rats forgot about their distaste for a substance that had previously made them sick. Dr. Todd Sacktor, head of the project, believes that the drug may be used in humans one day, and that it may also help enhance memories as well. We don't really have any specific info about the drug itself, or how it works, so until then... we'll just have to keep hoping that the lyrics to Use Your Illusion II fade on their own.
