Leave it to the BBC to say:
"New science discovery: Here's no real information about it"
This is actually quite a large deal. One physicist wrote that outside of finding life on another planet or directly detecting dark matter this is the biggest near-present discovery we could have made.
To simplify it grossly, this is pretty much the first observable evidence for inflation in the early observable Universe. Indirect evidence, but it meets enough predictions that we can start focusing on exactly which model of inflationary theory is the correct one.
