For anyone interested in CCD, I strongly recommend the book "Fruitless Fall" by Rowan Jacobsen. In it, he suggests, just like the SciAm article does, that CCD is likely a combination of multiple factors, including IAPV, nosema, pesticides, industrial farming, and other contributors. While this study is a good start, I won't hold my breath that CCD is over until we have much more evidence.
