Faster than the speed of light?

From Physorg.com:

Using their Stimulated Brillouin Scattering (SBS) method, the group was able to slow a light signal down by a factor of 3.6, creating a sort of temporary "optical memory." They were also able to create extreme conditions in which the light signal travelled faster than 300 million meters a second. And even though this seems to violate all sorts of cherished physical assumptions, Einstein needn't move over – relativity isn't called into question, because only a portion of the signal is affected.

I dunno--I learned in physics class that NOTHING goes faster than the speed of light; even a portion of a signal. Did they lie to me again?
