material scientists admire spider silk for being lightweight and strong.now another arthropod  product is getting into the act insect cuticle¹,the tough flexible material is inside insect skeleton.researchers at harvard  * institute for biological inspired engineering analyzed² the insect cuticle which includes chitin and other proteins,such the fiber³ also found in spider silk.then they advise method to produce material made up layer of chitin fiber. the result is on part with aluminum⁴ alloy⁵ for strength, but the half metal's weight. they call the stuff shrilk a combination of shrimp⁶ as describe the shrimp are good source of chitin and silk,its flexibility⁷ can be manipulated by adjust the water content just as insect too. the reaserch is in journal <advanced materials>.shrilk's creators say it could be a green alternative to plastic for a crash bag even diapers.its strength and biocompatibility could make it good for surgical⁸ suture or as a scaffolding for tissue regeneration.shrilk is a clear film,if it can be made to stay clear when thick,it could make a enterprise engineer * transparent⁹ aluminum obsolete¹⁰ in advance.
