Space Elevator Cable?

The Register reports that diamond is no longer the hardest material on earth.

A gigapascal is equal to about 10,000 atmospheres. The new material is harder by 490,000 atmospheres than diamond, which can handle 4,420,000 atmospheres. So it's pretty strong then. I wonder if "isothermal bulk modulus", the way hardness is measured, deals with tensile strength. I suppose at the very least it is a serious indicator.

A Space Elevator might be a step nearer then as this material sounds like carbon nanotubes to me.
