It's an active area of investigation, and you're right that there's yo-yoing. But note that the article discussed in your ref is published in Cell, the same journal that also published some of the original work it's refuting. As much as NatSciCell publish sensationalized work, high impact work pretty much universally gets published there still. It's like the nytimes. Popular to crap on it, but in the end they still put out good journalism.
