Nanotech's Unintended Consequences

If you've been following nanotechnology over the years, you've probably heard about Carbon Nanotubes, which are often the building blocks of some pretty great, prospective technology. Turns out that there might be some reasons for concern:

"A major study published today in Nature Nanotechnology suggests some forms of carbon nanotubes – a poster child for the "nanotechnology revolution" – could be as harmful as asbestos if inhaled in sufficient quantities."

Be careful, you scientists.
