Thanks for posting that. It is a very interesting article.
I especially like the following quotes:
"It turns out that the fiber is made of a number of nanostrands," Schniepp said. "Each nanostrand is a thin thread made of protein, less than a millionth of an inch in diameter."
The paper reports that a typical recluse-silk filament is made up of around 2,500 nanostrands.
He added that an accurate comparison takes into account not only the thickness of the recluse ribbon, which is a thousand times less than the thickness of a hair, but also the fact that the cross-section of the hair is ten times that of the silk strand. Consequently, Schniepp said, the silk cross-section is 1/10,000th that of a human hair.
