> “This new reinforcing procedure could also be applied to other animals and plants, leading to a new class of bionic materials,” how about silk worms? at least we know how to handle those in bulk.
There's a lot of effort going into just that, though there are some stumbling blocks researchers are still working their way through before we start seeing production scaled up. http://news.discovery.com/tech/spider-silk-silkworms-genetic...
[ed: insert dystopian sci-fi plot of scattered survivors of the nano apocalypse growing bullet proof vests from silk worms found in old industrial (nano)waste sites...]
I just wrote this up myself. The results are remarkable, but the credit seems entirely due to the spiders. Well, not entirely, but the data is so limited! They only got a handful of spiders, from the lab's back yard essentially, and a bunch of them died from nanomaterial exposure, malnutrition, or both after 1 trial! Yet despite the bargain bin trappings, the results are so incredibly cool! The spiders just... incorp…
> Who would have guessed Except for not being a dog, such a spider is anticipated in Goethe's little poem «Annonce» (Advertisement): A little dog is sought that never barked nor bit takes broken glass as feed leaves diamonds as - - (my own translation, but wouldn't be surprised if it has appeared in these words before)

A third (reboot) is already planned, you mean you want a forth?!
One where he starts as an actual spider and gets bitten by a radioactive man, just to give us something different forth time around.
Just when I'm full up on superhero themes it gets all interesting again.
Peter parker was just your average day Pholcidae spider, until one fateful day when he was exposed to experimental carbon nano-tubes. Now he must decide, will he use his new found super web powers for good, or for personal gain?
nanomagic spider silk: 5400 MPa (5.4 GPa)
Spider silk: 1600 MPa
Silkworm silk: 500 MPa
Aramid
(Kevlar or Twaron): 3620 MPa
Steel: 450 ~
2600 MPa

Nice discovery and thank you for sharing it. Concerning the article, there are a lot of superlatives which sometimes makes me wonder whether the author is overenthusiastic and still rational; Therefore a couple of comparions would be welcome for people who didn't study material resistance, e.g. "Such a web can hold a 2kg spade if it happens to hang in your garage". Can it?

So, for those that don't remember what "regular" spider silk is like, or kevlar: nanomagic spider silk: 5400 MPa (5.4 GPa) Spider silk: 1600 MPa Silkworm silk: 500 MPa Aramid (Kevlar or Twaron): 3620 MPa Steel: 450 ~ 2600 MPa If I'm reading http://en.wikipedia.org/wiki/Ultimate_tensile_strength correctly (and comparing the right numbers with the ones from the article...). At least kevlar seem to be in the same ballpa…
