Some studies find little or no risk. Others are alarming.

One reason nanomaterials can cause trouble is that they are small enough to evade the body's defenses.

"The take-home message for me is, the behavior of these particles is very complex," Gruden says. "When you take a nanoparticle and put it into the environment, you have to know how it's going to behave. And we don't."

Scary.

Ever get the distinct impression that we are being used as ONE BIG human experiment????
When was the last time you volunteered or
gave your permission to be used in a "test case"
experiment.
Until we demand THE TRUTH.....about what they are putting in our food, why they are irradiating and bio-
engineering the crops we harvest, why there are white lines in the skies everywhere, and the list is endless, we will be unknowingly used as the
"ultimate" lets-see-what-happens-if.....guinea pig!
