I just read quite a disturbing abstract on the ability of nanoparticles to affect our DNA without even entering it.Nanotechnology is a bit like GM crops; looks great, but has anyone done the real testing, or, like GM, are we the crash test dummies?
Nanotechnology is even being employed in water filtration. One new technology uses nanoparticles of aluminium to create an electrically charged medium to filter sediment from water.
One has to wonder:
(a) why aluminium of all things, given its chequered history and association with Alzheimers' disease
(b) given that nanoparticles are extraordinarily small, well below standard water detection system capability, how can any supplier gurantee that even a small knock to the filter won't release a shower of aluminium that will end up in our glass of supposedly pure water.
Another VERY interesting aspect of nanotechnology can be found here. It's the story of nanostructures dug up in Russia, suggesting technology capable of creating tiny coils as small as 1/10,000th of an inch... THREE HUNDRED THOUSAND YEARS AGO!
Again, the question must be asked.. what happened to the civilisation that created these tiny and technologically advanced artifacts and why is there no firther trace of their life?
