They have apparently "developed" a wasp that can kill the Emerald Ash Borer though im not sure if thats the cure.. The scary thing about losing Ash tree's is the fact that they are native to the area - we've already lost a huge amount of our tree canopy in my city as a result.  Hopefully one day people will be able to replant Ash trees - until then I need to figure out what to replace it with.  It's sad!
