This is a technique called squeezing, it in no way violates our fundamental understanding of physics. Heisenberg uncertainty is generally: 1/2ћ ≤ ΔxΔp. If you measure something in a way that you have complete uncertainty in the quantity p then you can have arbitrarily fine resolution in x.

It's interesting, but squeezing is a common technique, and this headline misrepresents the importance of this experiment.

It's not just the headline. Sentences like this are false:

> ...measure the spin precession rate much more accurately than previously thought possible.

since no one thought different.
