Something IS out there

I heard a very quick blurb on NPR as part of the hourly news update yesterday about gamma radiation coming from space, which scientists first discovered during cold war times. Short gamma bursts are credited with being colliding stars, but these longer bursts seem to indicate that they are maybe from intelligent life far away in the galaxy. I couldn't find a link to the story, on NPR or on space.com, but conspiracy theorists will no doubt delight in this news.
