What makes this headline news is that it gets around Heisenberg's Uncertainty Principle – the idea that position and momentum can't be perfectly measured at the same time. The principle states that recording either measurement will interfere with the other through a process called quantum back action.
As well as backing up the other study in demonstrating macroscopic quantum entanglement, this particular piece of research uses that entanglement to avoid quantum back action – essentially investigating the line between classical physics (where the Uncertainty Principle applies) and quantum physics (where it now doesn't appear to).
One of the potential future applications of both sets of findings is in quantum networks – being able to manipulate and entangle objects on a macroscopic scale so that they can power next-generation communication networks.
