As the saying goes, if it looks like a duck and quacks like a duck, it’s reasonable to assume it’s a duck. In light of a new rodent study, environmental scientists worry that the same might apply to asbestos.

Certain long carbon nanotubes — tiny cylinders only 20 micrometers long and perhaps a few micrometers wide — have the same basic dimensions as toxic asbestos fibers. A broad body of data has suggested that the damage caused by asbestos traces more to its physical dimension...
