This is a good, and disappointing read.
A "seminal" paper on Alz had to retracted because of some cooked up stuff.
Almost all research is dedicated to eliminating the plaques that are seen in the disease. But no good studies have shown that the plaques CAUSE the disease or are just a byproduct. And those that want to think outside the box tend to get the short stick on research funds.
I've relied on the tools provided by research to do my work all of my career. It's disturbing to know that the process can be really tainted. Tainted by close mindedness that won't allow "outside the box" research. Tainted by those willing to phony up results.
So while science works to provide answers in numerous fields, and gets great answers quite often, this kind of stuff fuels the doubters to question most of science. And that's bad fallout.
I think that early AID's research probably suffered from similar issues. Too much politics injected into a deadly disease.
Etc.
