Wonderful webs: Elastic data analysed
Date: Feb 15, 2013
Author: David Bradley
The full range of elastic properties of an intact spider's web have been catalogued by researchers in the USA using the relatively uncommon technique of Brillouin spectroscopy. The research offers an intriguing picture not only of one of nature's most fascinating structures but might also point the way towards novel "bio-inspired" materials.
