Scientists in Israel have developed a transparent material with "the hardest organic nanostructure known to man," according to Discovery News
. Based on artificial proteins similar to (and simpler than) the beta-amlyoid proteins that have been linked to Alzheimer's disease, and covered with transparent nanospheres, the new material is very, very strong: in order to cut it, a diamond-tipped probe would have to apply twice the pressure it would take to cut Kevlar
. Researchers see it being used for anything from bulletproof armor to reinforced steel -- but don't throw out your old body armor
yet! It could be years (if not decades) before this comes to market.
