Re: the role of (gel) images as the key aspect of a publication. To me this is very understandable, as they convey the information in the most succinct way and also constitute the main data & evidence. Faking this is so bold that it seemed unlikely.

The good news IMO: more recent MolBio methods produce data that can be checked more rigorously than a gel image. A recent example where the evidence in form of DNA sequencing data is contested: https://doi.org/10.1128/mbio.01607-23
