This is not an accurate description. It makes the result sound much
more exotic and science-fictiony than it is. They've found a better
way to do magnetic levitation -- that is, to use magnetic forces to
balance the force of gravity.

If you call applying another force to balance gravity "controlling the
amount of gravity," then my chair is controlling the amount of gravity
on me right now.
