An interesting article at SAGE Crossroads examines public Alzheimer's funding in the context of the wider effort to understand - and eventually cure - aging. Is the sheer weight of Alzheimer's money flowing from the NIA distracting the scientific establishment from equally important research into the aging process? Or is the additional healthy life gained for many people through defeating Alzheimer's worth the extended detour? This seems to be another prevention versus cure argument, but there's a little more to it than that. Big science, we are reminded, is very much a human, political process: people with the same end goal in mind disagree over how to reach their target for both the best and worst of reasons.
