Gravitational anomaly on Earth?

https://phys.org/news/2017-07-scientists-gravitational-anomaly-earth_1.html

Me no comprendo. what do they mean by gravitational anomaly anyway?

I think it is a case of a journalist trying to dumb it down for the layman and failing (possibly because said journalist didn't understand it either).

Is this 'anomaly' something that relates to sci fi stuff like anti-gravity? What is the practical use of such?

No, I don't think so.

What is the practical use of such?
They seem to suggest it has uses in the semi conductor industry, but far more importantly for us, it provides a test of quantum theories of gravity and general relativity. If confirmed it provides either confirmation or contradiction to particular theories in fundamental physics.
But it requires specialist knowledge (that I lack) to know exactly what its all about.

I wonder what the connection would be to more sensitive sensors they alluded to? I guess it's one of those fundamental discoveries where nobody knows what it will lead to.
