From New Scientist:
Spiders might soon give you goosebumps in a good way. Strands of spider silk have been used to make violin strings that have a unique and thrilling sound, thanks perhaps to the way the strands deform when twisted.
Shigeyoshi Osaki at Nara Medical University in Japan has studied the properties of spider silk for 35 years. In the past decade he has focused on trying to turn the silk into violin strings, even taking lessons on what was required of a string in terms of strength and elasticity.
