As best I can tell they're on the trail of a much better treatment, but not a cure. The patients get no worse, but no better? Still a good thing.

I have a subscription to Nature, but not the Medical variant. They haven't put the December papers online yet. If my subscription lets me download this paper I'll mail it to Gen and see if she can tell what they've got.
