Retraction Watch

Nothing is infallible. 

Axioms induced from genuine empiricism often turn out to be incorrect. To address this, a core value of science is its unequivocal capacity for correction. To rationally adjust one’s opinion in the light of new evidence (often labelled Bayesian reasoning). 

Unfortunately, some 'scientists' deliberately falsify data. This is a small, but very damaging problem. It can severely mislead subsequent research and ruin careers. However, just as old scientific paradigms are retracted (to make way for new, more accurate ones), previously approved peer-reviewed scientific articles can be retracted from the literature should their authors be discovered fraudulent.

Retraction Watch covers this dirty, but essential process and provides an excellent window into the plasticity of contemporary science.
