Sir, the Bloggers have engaged their cloaking device …
Just Star Trek? Wishful thinking? I guess not. Mathematicians have found a way to make light travel backwards.
Graeme Milton and his team at Utah University and Nicolae-Alexandru Nicorovici at Sydney University of Technology have created a formula based on a new superlens technology that makes light behave in unconventional ways – employing a phenomenon known as negative refractive index – making light travel backwards.

How does this work? Complicated, I’m not going to fool you. Here’s what I get. We know that we see because light is reflected into our eyes. Humans only see part of the spectrum of light (the visible spectrum). Now, what these folks have figured out and been able to do is find a way to bend light and send it back without part of the spectrum. Right now, it looks like things like the applications are going to be in terms of shielding electromagnetic signals or military applications.
So no cloaking device for your car to be invisible, but hey we can dream
