BBC News. “World’s ‘lightest material’ unveiled by US engineers” 18 November 2011 <http://www.bbc.co.uk/news/technology-15788735>.

A team of engineers claims to have created the world’s lightest material.  The substance is made out of tiny hollow metallic tubes arranged into a micro-lattice – a criss-crossing diagonal pattern with small open spaces between the tubes.
