Carbon nanotubes mimic asbestos in early study - Yahoo! News: "Strong, versatile little 'nanotubes' made out of carbon are considered future stars in nanotechnology research in medicine and industry. Now a study finds that longer threads of the stuff mimic the toxic qualities of asbestos, renewing questions about how carbon nanotubes can be used safely."
Soon after the invention of many of these carbon nano-objects, concerns were raised about the possibility of damage to the lungs, and even the possibility that the objects could be small enough to penetrate human cells. Now, this "early" study seems to confirm the potential dangers of these products. Early, however, is not the term I would use when referring to the study, as it is rather late. These carbon products have been experimented with for years now, and they have even made into mass-produced products, such as stain-free khakis. But hey, I guess it is less than the decades it took us to realize that asbestos was dangerous.
