Conventional effects that look like anti-gravity
Magnetic levitation suspends an object against gravity by use of electromagnetic effects. While visually impressive, this is not an anti-gravity effect.
Critics of various alleged anti-gravity devices often suggest that unusual effects observed around them are due to electromagnetism.
A tidal force causes objects to move along diverging paths near a massive body (such as a planet or star), producing effects that seem like repulsion or disruptive forces when observed locally. This is not anti-gravity. In Newtonian mechanics, the tidal force is the effect of the larger object's gravitational force being different at the differing locations of the diverging bodies. In Einsteinian gravity, the tidal force is the effect of the diverging bodies following different paths in the negatively curved spacetime around the larger body.
Large amounts of normal matter can be used to produce a gravitational field that compensates for the effects of another gravitational field, though the entire assembly will still be attracted to the source of the larger field.
Physicist Robert L. Forward proposed using lumps of degenerate matter to locally compensate for the tidal forces near a neutron star.
The accelerating expansion of the universe due to dark energy is an effect that causes a large-scale repulsive force. However, this is not gravitational in nature, and so is not anti-gravity.

This is what Friedman had to say about the development:
papers can also exert upward forces... but are not anti-gravity. It is also true that 4 atoms of Element 115 were created at a huge accelerator in Dubna. Half life was in the millisecond range. Lazar claimed at one time that Los Alamos had 500 pounds. No way Jose. Half life is too short.
