A journal reviewing the work for publication prohibits the ExAC researchers from speaking with journalists about the manuscript posted on bioRxiv.org, one researcher involved in the project told Science News. The work has yet to be peer-reviewed and researchers are not allowed to “publicize” their findings before they have been vetted by their peers. Other researchers have already viewed the manuscript on bioRxiv.org and pointed out a few minor flaws, including broken links and formatting errors. No one has yet criticized the data or analysis.
