This is the latest study linking shorter telomeres to disease (there are over 10,000) that once again falls victim to proving obvious yet useless information. In this study, they linked smaller hippocampal volumes (seen in Alzheimer’s) with shorter white blood cell telomeres in a subset of women with a genetic prediliction for Alzheimers (the abnormal ApoE3 gene).
This endless, incremental, reiterative, and staid method of advancing knowledge is challenged by what I call the “Ginsu Principle”. You could sell many distinct knives for cutting bread, aluminum cans, tomatoes and wood. And you can have different theories for how these knives cut those substances. Or you could just accept that a knife can cut a lot of things because it’s sharp. Our research into telomere biology violates the Ginsu Principle in a big way.
