Here’s the research paper: https://advances.sciencemag.org/content/5/7/eaaw2563.full
A depressing lack of details in the article.

So while they "are" entangled, they are apparently not entangled enough in a stable way such that a change to atom A would be picked up as a new change to atom B (thus, having successfully transferred some sort of information), because the quantum state breaks down somehow.
So what exactly is this a picture of? Two entangled photons? I don't have the background for the full maths involved here, but there's not enough in that article to tell me why it's exciting ...
In short: - Create beam of entangled photons - Split off half of them - Pass one half through liquid crystal making them behave funny - Photograph the ones that where not passed through crystal and, lo and behold, observe the funny behavior
Strange way of throwing Einstein's name into the title for linkbaiting sake. It's not his particle entanglement but John Bell's if anyone's, calling it "spooky" is Einstein's contribution, at least in the context of the article. I had the BBC as a reference on journalism, but from a quick glance over the headlines at least its website looks like it's lost some decency in that respect.
Ok, we've deeinsteined the title above.
(For those unmotivated to Google: it is a word which only occurs once in a context, book ... or the whole world)

The mathematics of entanglement doesn't allow it to be used for communication.
