Spider Silk is stronger than Steel. In fact it is even stronger than Kevlar, the material that makes bullet-proof jackets. Though it is not as strong as carbon nanotube fiber, it is more flexible and easier to make.

Cheryl Hayashi: The magnificence of spider silk
2011/12/07 にアップロード
http://www.ted.com Cheryl Hayashi studies spider silk, one of nature's most high-performance materials. Each species of spider can make up to 7 very different kinds of silk. How do they do it? Hayashi explains at the DNA level -- then shows us how this super-strong, super-flexible material can inspire.

Molecular Biomechanics: Spider Silk
2012/07/26 に公開
In this movie, we are using an artistic approach to communicate a scientific topic. Dr. Agnieszka "Bronka" Bronowska, a HITS researcher and artist, has designed and produced a video on spider silk and its properties. The reason why spider silk is so highly elastic and at the same time stronger than steel lies in the nano-scale.
The Molecular Biomechanics research group (head: Dr. Frauke Gräter) of the Heidelberg Institute for Theoretical Studies (HITS) explores how physical force interacts with molecular processes using computer based methods. One of its research topics is the fascinating property of silk, which is more tear-resistant than steel.
