A new composite material called "Proteus" has been discovered that is only
15% as dense as steel but is much tougher and is extremely difficult to cut
or drill through and could find applications in things like body armor,
locks and bank vaults. The Researchers got the idea from examining the
shell of the abalone which is also a composite material and thanks to its
particular construction is 3000 times more break resistant than the sum of
its parts.
