Spider silk is one of the more extraordinary materials known to science. The protein fiber, spun by spiders to make webs, is stronger than almost anything that humans can make.
The dragline silk spiders use to make a web's outer rim and spokes is amazing stuff. It matches high-grade alloy steel for tensile strength but is about a sixth as dense. It is also highly ductile, sometimes capable of stretching to five times its length.
This combination of strength and ductility makes spider silk extremely tough, matching the toughness of state-of-the-art carbon fibers such as Kevlar.
No word in the article on how close to the necessary tensile strength for a space elevator they come. Or how quickly the spiders got cancer. But at least it's a simple process. I wonder if the same technique will work with silkworms, which are commercially viable (something that spiders aren't).

No word indeed about that cancer thing, that is just Andy's attempt at humour. Better luck next time. Thanks for the article, though.

Actually, it was SirFinkus' idea (and I didn't check if there was any research on it - isn't that what editors are FOR?). Mine was a "your mom" joke, which is not something I usually rely on but I was really tired. Here's how it went down in the IRC last night:

Do spiders even live long enough to develop cancer? What is the average life expectancy of a spider? There probably isn't enough time for them to develop cancer under their normal lifespan. So it's probably safe to feed them some delicious nanotubes, perhaps PETA should have a campaign. But I doubt they ever will since spiders just are not cute enough.
The more interesting thing might be what happens to their offspring; do they get any kinda of special powers or not.

Age has little to do with it, number of cell divisions is the issue. Every time the cells divide you have the possibility of damage that will cause cancer. You can damage DNA at other times, but it tends to be more likely to be repaired correctly than if it's just one strand.
Humans have cells dieing and being replaced rapidly. The life span of a cell in the human body is between about 3 days and about 50+ years.

Tell that to whales. They have far far more cells, and so more cell divisions.

Does that mean that naked mole rats are actually dwarf giant kaiju monsters?
Hmm. Your ideas are intriguing to me and I wish to subscribe to your newsletter.
