For headline news, I think we would need studies that show that this effect changes results from high ranked studies that used mice. But publishing these would be hard in peer reviewed journals because the peers who will referee the papers will likely be researchers whose own previous publications would be questioned by these new results. In the same podcast, Bret talks about the failings of peer review.
Another problem is that even if the results are published, usually it takes a long time for information to diffuse into the wider community. I assume this is largely because finding a novel ideas is like searching for a needle in the haystack of common knowledge that has been spread far and wide.
