Thank you (and also to fennecfoxen)! My background in physics isn't sufficient to be sure of my interpretation of the details here.

I usually ignore implications of immediate world-changing revolution in popular science reporting (they're invariably nonsense in those fields where I'm qualified to come to a definite conclusion), but Nature (and certain other publications) are more circumspect, at least often enough to check first.

Of course, I'm still happy that the results are interesting!
