Scientists invent lightest material on Earth. What now?

An Ultralight metallic microlattice -- which is 99.9% air -- is so light that it can sit atop dandelion fluff without damaging it Many ultra-low density materials have already been produced based on carbon nanotubes, metallic foams and the like. But these have random structures, notes materials scientist Tobias Schaedler of HRL Laboratories in Malibu. His team?s new material, described this week in Science, consists of a regular arrangement of metallic tubes intersecting at nodes and is made by plating nickel-phosphorous onto a carefully produced polymer micro-lattice.
