I remember a few years back where a few biologists released a paper on how to weaponize influenza from CRISPR (IIRC). Before it got produced (or after?) the DoD stepped in and had them redact and classify their paper to have it (re-)published. Does anyone else remember this? Maybe link to the paper, as well?
