An interesting advance in materials science:
A new artificial material effectively cannot be cut, holding out the promise of lightweight but cut-proof bike locks, security doors and protective clothing.
Its inventors embedded ceramic spheres in aluminium foam to create a material that couldn’t be cut with angle grinders, power drills or water jet cutters. They dubbed it Proteus after the shape-shifting Greek god, for the way the material metamorphosised in different ways to defend against attacks. [NewScientist]
OK, so you can’t cut it. How does it hold up to a blowtorch?
