They are processing the data taken by Kepler since early 2011; some interesting signals have been found (a candidate signal is referred to as a Kepler Object of Interest or KOI), but as they are quick to point out, these signals so far can all be explained by terrestrial interference. If a single signal comes from multiple positions in the sky, as these ones do, it is most likely to be interference.

So, sadly, it’s not aliens. But the good news is the method works! The astronomers use automated software to look for what could be artificial signals, and the computers flagged these detections. As the project ramps up and they start looking in earnest at the hundreds or even thousands of exoplanets orbiting stars out in the galaxy, they’ll certainly find lots of signals like these — interference from somewhat closer and more mundane sources.
