Fake journals and conferences in NYT
Conferences that invite people at random, for money, are bad enough. Those that mimic real conferences are worse. The New York Times reports that people signed up for Entomology-2013, sponsored by "The OMICS Group", mistaking it for the scientific-society-sponsored Entomology 2013. I've discussed this problem before. The NYT article also discusses fake "scientific journals" that publish garbage for money. Since real journals vary in quality, and many charge authors for some of the cost of publication, it may sometimes be hard for people outside the field to tell the difference.
Real scientists publish in journals with scientific-sounding names, but publication in a scientific-sounding journal is no guarantee that the conclusions are correct or that the author is a real expert.
