Nanowhat?

Luke 9:48 points out the least shall be the greatest.
Does this apply to science as well?
The chemical reaction in Dynamite gives the compound great explosive power - but the smaller nuclear reaction gives a nuclear weapon even more power.

Can the same be said of nano-additives in many consumer products?
An aol story (front page, story 10) http://www.aolcdn.com/aolnews/cancerresearch.pdf
points out that more than 10,000 over the counter products contain nano-titanium,
and that these products have an effect at the chromosomal levels of DNA.

"Better living through science?" - says who?
