SWNT can be toxic, in fact they can be very hazardous. Now I'm not completely sure about single walled, but I know multi walled CNTs, when they are functionalized as to by hydrophilic, can have their the toxicity drop to what the researchers saw to be safe levels.
I'd find links but I don't have time.
Or at least partial BS.
I work at a nanotube R&D lab and one of the things we're working on (which I am personally involved with) is making carbon nanotube thread. I've read over and discussed the very paper that is mentioned in the article; also I've looked at what the University of Texas at Dallas is doing. Pulling SWCNTs (single walled carbon nanotubes) from a furnace does not create the same level strength due to the tight wrapping of CNTs as using van der Waals forces present in aligned MWCNTs (multi walled carbon nanotubes) when pulling thread from an aligned forest of nanotubes. While the individual tubes are stringer than almost anything, they do not adhere well to each other and tend to slide apart when in a rope. C
They may have some fibers that are stronger than Kevlar, I've made some myself infact. But it was only that strong in comparison when measuring Young's modulus because it was so small as to be neutrally buoyant in air and nearly invisible to the human eye. And, unfortunately, so far that strength doesn't scale.
So, yes they probably have made super fibers, but I highly doubt they are usable for the applications they are claiming.
that is a very valid point, i work in a nanotech lab. we are working on a project invoving CNTs carbon nanotubes) electrified in water. because of nanotube unique properties, any electrical field is greatly amplified. the small surface area of the nanotubes creates areas of extremely high voltage that can easily cause electrolysis.

Any discussion on science or religion will quickly devolve [pun] into a pointless flame war over ID vs. Evolution
Lets stop this here and worry about more important things
Not only this, up until recently race was a factor that was not able to be traced in a blood test. It was found that race can in fact be determined and traced, this is now become more practical and useful as it can help profile a criminal, as well as trace family lines, i believe Oprah had special in which the racial histories of different people were determined to help find ancestors/distant relatives, though i don't know if they used the same process.

they do have a dating service, see http://www.google.com/romance/ all i can say is, join us...

hell yes, that guy said it would grow 3" over night! shyster took my money! seriously though, i think thats a great idea
You see, the cat is not in fact dead, it is merely pineing for the fjords
