Re: 'important points' -EDIT


All of the toxicity studies related to silver nanoparticles (pure silver).

Some (not all) of the articles on silver-resistant bacteria were indeed testing against AgNO3 (silver nitrate).
However, do you have any reason to believe that the organisms resistant to AgNO3 are not also resistant to Ag+? They've identified at least some of the plasmids encoding silver resistance (which confers resistance to AgNO3):

The reason they were testing against AgNO3 is because that is the silver compound most frequently used.

My point was not to say that if someone uses silver, they will necessarily become resistant to it; I was merely pointing out that those who say it's impossible or won't happen don't appear to be supported. If everyone is using silver chronically, whether they have a need to use it or not, silver resistance is a very real possibility, although in some cases the fitness cost may prevent it from being widespread (although this is a bit of an unknown).
Resistance to nanoparticles may be a different issue.

Nope, never read the book. I don't much read popular press containing new theories of human physiology or disease - they tend to be high on claims and low on science. My assumption is that if someone with scientific credentials is doing important work, they'll publish it in a reputable scientific journal so that their claims can be evaluated by other scientists rather than a by an often-uninformed lay public.

EDIT: I didn't mean the previous statement to sound snobbish. I meant that when a scientist makes what he believes is an important finding or has a theory he believes to be correct, he'll want others to test it, validate his findings, etc, and write responses that perhaps point out the weaknesses in his argument. None of this is likely to happen when he's publishing in the popular press rather than scientific journals.
