This website tracks everything related to scientific misconduct which often leads to retraction of scientific papers.

I'd like to post this link to show that science, overall, is self-correcting and there are many scientists making sure this kind of papers don't get a pass. Of course, it also shows a subset of scientists are ready to fabricate data to get their paper published, but from my experience, in my field, that subset is relatively small.

Also, reading some of the stories can be quite addictive, if you like gossip.

I once got a paper retracted through them when i noticed something was amiss in a paper i had just read. I was a starting scientist, so my hat tip was anonymous.
