The one word you won't find is danger. The way that word is avoided is comical to me.

If you have any exposure, contact me. I had a minor encounter myself and can steer you to more inside info.

Prey by Michael Crichton

Prey is a techno-thriller novel by Michael Crichton first published in hardback edition in November 2002 and as a paperback edition in November 2003 by Harper Collins. According to IMDB there will be a film adaptation due out in 2007; details are unavailable. Like Jurassic Park , the novel serves as a cautionary tale about developments in science and technology; in this case, nanotechnology.

The book features relatively new advances in the computing/scientific community, such as artificial life, emergence (and by extension, complexity), genetic algorithms, and agent-based computing.

The novel involves nano-tech as the basis for the AI.

Contamination of the skin is typically a red sore itchy spot with dark dots.

What contamination may look like under microscope.

Anyone remember the film "Them!"? The cause of the 20ft giant ants in that one was given as nuclear contamination, so you could call that a "cautionary tale" - but in fact it was just an excuse for filming screaming girls, broad-shouldered men with guns and foam rubber monsters. It was a work of fiction, designed purely as a spectacle, with no basis in fact.

Replace "giant ants" with "grey goo", and "nuclear contamination" with "nanotech contamination", and hey presto! you have a Michael Crichton book! A B-movie work of fiction, leave-your-brain-at-the-door entertainment.

If you want a better example of nanotech in action, check out Neil Stephenson's "The Diamond Age". It's a bit slow, but it has plenty of new ideas, and it's a whole lot better written than Crichton's stuff.

FWIW, Donuel is right that caution is needed with nanoscale particles. The high surface area and high mobility of particles means that how a substance behaves in a large mass might be rather different to its behaviour when it's in nanoscale particles. The size factor also becomes an issue when they can penetrate cell walls.

All this is just about nanoscale particles, though. A nanoscale particle is to a nanomachine what a rock is to a silicon wafer - it might be the raw ingredient, but *boy* is there a lot of work needs doing on it! :-) As far as nanomachines go, we haven't invented the wheel yet.

"rather different to its behaviour when it's in nanoscale particles. The size factor also becomes an issue when they can penetrate cell walls."

'Talcum powder' used to contain 'Talcum' - but it was found to migrate inside the body - nobody knew what the long term effects might be - now it has been replaced by a kind of starch.

The one word you won't find is danger. (Donuel)

Firstly, it is not true.

Secondly, if you knew what you are posting about you'd know that the word to search for is not "danger" but "risk". The report is full of risk analysis and assessement.

And isn't this really a "below the line" BS topic?
