Saw this news on MSN just now..

Invisibility Cloak on the Horizon, Scientists Say
By Steven Musil, CNET

Scientists say they are a step closer to developing materials that will render people and other objects invisible.
Researchers say they can redirect light around 3-D objects using metamaterials--artificially engineered structures created at a nano scale that contain optical properties not found in nature, according to an Associated Press report.
People see objects as a result of the light reflecting or scattering off them. This new mixture of materials has "negative refractive" properties that keep light from being absorbed or reflected by the object, allowing only the light from behind the object to be seen. Essentially, the material bends visible light in a way that eliminates the creation of reflections or shadows in much the way water flows around a stone.

The findings, to be released later this week in Nature and Science, were made by scientists at the University of California, Berkeley, led by Xiang Zhang. The research, which was funded in part by the U.S. Army Research Office and the National Science Foundation's Nano-Scale Science and Engineering Center, could have broad applications, including for the military.
But the materials work in limited wavelengths, so they won't be used to hide buildings from satellites, said Jason Valentine, who is a co-author of one of the papers.
"We are not actually cloaking anything," Valentine told Reuters. While the Harry Potter series of books and films has made the idea of a personal "invisibility cloak" popular, he says, "I don't think we have to worry about invisible people walking around any time soon. To be honest, we are just at the beginning of doing anything like that."

This made me to think..
Can we trust the people with such knowledge to not use it in the wrong way?
A wise sensei once said "A little knowledge is dagerours, so is a lot"..
I always believed that there is only 1 source of knowledge but the medium in which it comes varies.. and because of this, the medium has the upper hand in influencing the recepient towards a preception of its choise.. Therefore, intentions are far more important..

We're really progressing in science and almost every thinkable item has somewhat started to become reality..
Remember: In the absence of light, darkness prevails..
The right tool in the wrong hands will always be used the wrong way..

So, what would YOU do it you could be invisible? :)
