- New material "perfectly absorbs light," converting it to heat:
While research into light refracting metamaterials has produced a few neat, if very small toys, some groups, like the British Royal Navy, are taking cloaking devices quite seriously. Mostly, this type of thing works on negative refraction indexes, the materials merely bend light, visible or otherwise, around themselves. While this would be incredibly useful for Motoko Kusanagi or Klingon Birds of Prey, cloaking materials don't have a lot of use in generic, not blowing up the bad guys, applications.
A collaboration between Boston College and Duke University has developed a metamaterial that might be slightly more useful to scientists and engineers. Their new metallic metamaterial absorbs light perfectly. The resonating materials can absorb both the electrical and magnetic properties of electromagnetic waves over a narrow frequency range, turning the light into heat.
“Three things can happen to light when it hits a material. It can be reflected, as in a mirror. It can be transmitted, as with window glass. Or it can be absorbed and turned into heat. This metamaterial has been engineered to ensure that all light is neither reflected nor transmitted, but is turned completely into heat and absorbed. It shows we can design a metamaterial so that at a specific frequency it can absorb all of the photons that fall onto its surface,” explains Boston College's Willie J. Padilla, a leading researcher in optics and metamaterials.
As the material's properties make it easily scalable, though the absorption range is narrow, it could be tuned to a vast portion of the electromagnetic spectrum. Some of the possible uses for a material like this include light detectors and electronic imaging applications.

Now am i right in thinking that what you are saying is these insurgent's added the guy in or something ?

This video only pisses me off and makes me wish the place would be nuked and get it over with already. What a propaganda video with all the allah singing. BTW, I'm not saying the OP is using the video as propaganda, just that it's easy to tell this video was made for that purpose.
I don't know if the 'snake' thing is real. It sort of looks fake, like it was added in after the fact but I guess you never know. If it was the enemy, why would he run onto the tank and do nothing? If it was the enemy then you would think he would have dropped a grenade or something inside the tank while up there. And you know the video would have shown the second tank blowing up.
I don't know but I think it's fake.
