For those interested in the post about finding advanced civilizations in other galaxies by their heat emissions, Paul Gilster at Centauri Dreams has a write up about the study, including links to additional material as well as the actual paper.
I found that this part clarified the seeming contradiction in the Science Daily article.
The currently reported work tells us that none of the galaxies resolved by WISE in this study contain Type III civilizations that are reprocessing 85 percent or more of the starlight of their galaxy into the mid-infrared. And as mentioned above, out of 100,000 galaxies, only fifty show a mid-infrared signature that could be considered consistent with reprocessing more than 50 percent of the starlight.
These fifty point to the further investigations ahead.
The overall endeavor of which the study is a part appears to be named G-HAT (Glimpsing Heat from Alien Technologies). Gilster links to a site that looks like it has lots of additional information on it, along with some interesting articles.
