Nanohazard Redux

I’ve posted previously about the potential biological hazards of nanotechnology and how little is understood about the possible dangers that could result from indiscriminate use of this technology. Now there is evidence that long, straight nanowires can cause mesothelioma exactly in the same way that asbestos fibers do. Nanotubes in other form factors do not seem to pose the same threat, so clearly there is something about the physical properties of the nanowires and not some underlying mole
