As far as I can tell this is genuine, rotating superconductors have been postulated to generate such a field since the early 1970's but it has taken until now to measure the effect reliably enough to account for all possible sources of experimental error.

I am very reluctant to belive any claims to have proven the General Theory of Relativity wrong, unless the experiments have been repeated independently. If the results were true I would also expect prestigeous journals like Science to feature articles about it. It could be interesting, but most likely it is BS.
BTW, for those who care to check, the most relvant publication seems to be the one here.

I am also very reluctant to believe anything that disproves General relativity. But don't forget, relativity is still a theory, and by defenition a theory is an approximation. Newton's theories made an outstanding difference to our lives until Einstein postulated special, and then later general relativity. But both of these theories are just more accurate "approximations" of the world we see around us. In time, general relativity will fall by the wayside as an even more accurate view of the universe becomes apparent. String theory maybe.

Some semantics:
If it really disproved it, it wouldn't matter what you believed.

From my reading of the articles,I do not believe that GR has been "disproved" any more than Newtonian Mechanics was "disproved" by the development of quantum mechanics or Einstein's Relativity. Einstein himself knew that GR was incomplete. We will no doubt in time find the incomplete bits of the puzzle. Whether or not this will involve a reformulation of physics as radical as that of the early 20th century is still up in the air....

Waverider, thank you, my point exactly. Every new theory we see is just a better and more refined approximation of what we see around us in the world around us and what we see in experiments. GR can NOT be 100% correct because we cannot marry it successfully to Quantum Mechanics. And we cannot come up with a Quantum theory of gravity either. GR breaks down when we get to such things as singularities and the big bang (Which is also under scrutiny) We are in a very new age of physics at the moment, for the first time in history, our theories are outstripping our experimentational skills. Will we ever know the mind of god?

Some of us are working on it.
As to saying that theory now exceeds experiment, theory and experiment have always been leap-frogging each other. Remember, when general relativity was first formulated no one could test all of its predictions. That eclipse thing that is often hailed as the first proof of GR was actually nothing but hype.
