exoskeleton and arachne

The Verge reports on an international, interdisciplinary team of researchers who are not only looking at the amazing strength and tensile properties of silk—both from silk worm cocoons (previously here and here) and spider webs—to make lighter and stronger combat gear and body armour and for internal medicine as well.
Naturally flexible and less likely to be rejected and breakdown inside the body than the screws and plates meant to hold us together while we heal, doctors could use threads of silk to stitch us up. The researchers are also experimenting with engineering silk (previously) that has disinfectant properties and materially fortifying bones with a protein (fibroin) isolated from silk.
