"A team of engineers claims to have created the world's lightest material. Made from a lattice of hollow metallic tubes, the material is less dense than aerogels and metallic foams, yet retains strength due to the small size of the lattice structure (abstract). The material's density is 0.9 milligrams per cubic centimeter. Among other things, it's potentially useful for insulation, battery electrodes, and sound dampening."

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.
The researchers say the material is 100 times lighter than Styrofoam and has "extraordinarily high energy absorption" properties.
Potential uses include next-generation batteries and shock absorbers.
