This is not the first time someone claims there is a fifth fundamental force, but this time there may be good experimental clues, considering the reputation of those now involved (from UC Irvine). This is fascinating if true, and it has already been tied, albeit prematurely, to the search for dark matter.
The weak nuclear force is normally associated with radioactive decay... Verification is required, as with all matters science, but this is very intriguing.

And to complete the picture, here is a skeptical physicist's opinion about it all, albeit only judging the papers' authors and not the data http://www.livescience.com/55283-has-a-fifth-force-been-discovered.html
