Except I have. There have been multiple groups working on this, and they have shared their results. Some published, some on blogs. Some have been unsuccessful in getting their noise floor low enough to detect the effect. Those who have (multiple groups now), have found something. That's why this is interesting. This sort of experiment requires a very expensive, delicate laboratory. No one is going to run a replication of this and then not publish in some form, even on a blog or a conference poster.
