Einstein described gravity as a property of mass and space; there's no way in which to believe gravity could be attenuated if that were actually the case.

A number of more recent theories describe gravity in terms of electromagnetic and electrostatic forces. The most interesting such theory describes gravity as an electrostatic dipole effect, and would easily allow one to believe that it could be attenuated in the manner your article describes.
