All the time. W = mg; where W is weight (the force of gravity), m is mass, and g is acceleration due to the force of gravity.
If you are talking about experiments using or discovering gravitons (the string predicted messenger particle for the force of gravity), then no experiments have been conducted that I know of. Several have been proposed, but they take sources of energy that are currently unavailable. There are some super super colliders in the works that may be able to penetrate down to the graviton level, but that is uncertain.

If you don't mind an individual speaking for himself, I've given it a shot. http://360.yahoo.com/noddarc there is an experiment I have proposed to be done in outer space that would determine what generates the force of gravity (scroll down to "An Experiment You Can Help With"). Outer space was chosen because the experiment is able to be performed where all outside influences are negated.

Can you clarify your question. It is very vague.

What the heck do you mean by that?
