Scientists funded by the European Space Agency believe they may have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity.

It will be interesting to see if this holds up. People have been playing with the idea of there being gravitational oddities around spinning superconductors for some time. But previous attempts to measure it have been somewhat erratic.

If it does hold up it may have major implications because it is the first directly measurable violation of general relativity due to quantum mechanics. And thus could be very useful for people trying to combine those two theories.
