REUTERS - A metal developed by a team of researchers from University of California at Irvine, HRL Laboratories and the California Institute of Technology is pictured resting on a dandelion fluff without damaging it in this undated publicity photo released to Reuters on November 17, 2011. The metal, which is about 100 times lighter than styrofoam, is the world's lightest material, according to a press release by the team.
