Scientists get first look at nanotubes inside living animals:
"'Carbon nanotubes are much smaller than living cells, and they give off fluorescent light in a way that researchers hope to harness to detect diseases earlier than currently possible,' said research co-author Bruce Weisman, professor of chemistry. 'In order to do that, we need to learn how to detect and monitor nanotubes inside living tissues, and we must also determine whether they pose any hazards to organisms.'"

Thanks again to Robot Wisdom, what freaked me out about this was the fact that we are capable of creating things "much smaller than living cells"! These things can be placed inside us and we wouldn't have the slightest idea they were there. Nano-technology is not sci-fi and not a dream. It is reality. Incredible.
