Very surprised you haven't heard of the PLOS One publications. They are very well-known in the scientific and medical communities that I have frequented. https://en.wikipedia.org/wiki/PLOS_One

It is a threat to the common for-profit publishing model that Elsevier and others have, so that may be part of your skepticism.

The major journals such as JAMA and NEJM have had their share of fake publications recently with plenty of very embarrassing retractions. Check out KHH (khh.org) or Science-Based Medicine (sciencebasedmedicine.org) or Respectful Insolence (respectfulinsolence.com) or Incidental Economist (incidentaleconomist.com) for many examples.
