Recently a team of scientist from the OPERA experiment measured a cloud of neutrinos going faster than the speed of light. Their measurement was very sound saying that the neutrinos were traveling about 64 nanoseconds faster than the usual speed limit (Which is not very much). However, A recent study may suggest that this whole thing might be explained with relativity.
see paper). He says that just like when you have a one meter long of straw hold by your hand, an observer away from you will see this meter straw much shorter. This is because the universe makes sure everything has the same speed. In other words, If the only speed that the Universe claims to be the speed limit, no matter what. The universe will make sure to make that happened. We know this because Einstein found that the speed of light is the same for every observer, so this would mean that being away from 1 meter long straw or close to one it will still be, however, a one meter straw for every observer , even if it looks shorter or just like one meter straw being hold by your hand.
But I must quote the Bad Astronomer on this issue about his last post (Which I agree): "As I recall from the foofooraw that unfolded after the initial announcement, the original experimenters said they accounted for all relativistic effects. The paper they published, however, didn't include the detail of how they did this, so it's not clear what they included and what they might have left out. It's possible van Elburg might be right., but I expect we haven't seen the end of this. After all, not long after the announcement, a physicist asked if they had accounted for gravitational time dilation - like relative velocity, gravity can also affect the flow of time, throwing off the measurement - and the experimenters said they had."

If this discovery by van Elderburg is incorrect...This might as well be the beginning of new physics and new theories to apply to our technology. I'm very exited about this and is something that is very important to be clarified once in for all.
