This has happened very recently to almost no media attention. From a scientific perspective, it is a really interesting accomplishment - the effort is more than merely selective breeding of "extinct" visual characteristics like the Quagga Zebra project. The actual genome changes are about 15-20 from standard grey wolves. Still, those are the ones associated with size, musculature, and ear shape which is also distinctive. Not sure what one does with these things should they prove to be fertile and to breed true to the genome construction. After all, they went extinct because the mega fauna on which they preyed vanished, Imagine what a pack of these could do to an elk or cattle herd. On the other hand, imagine a trophy display of an Alpha dire wolf carrying a mule deer in its jaws.
