Erin joins the TWiVirions to discuss a computer exploit encoded in DNA, creation of pigs free of endogenous retroviruses, and mutations in the gene encoding an innate sensor of RNA in children with severe viral respiratory disease.

The TWiVsters describe a mouse model for MERS coronavirus-induced acute respiratory distress syndrome, produced by CRISPR/Cas9 editing of the murine gene encoding an ortholog of the virus receptor.

The TWiVeroos examine a reverse spillover of Newcastle disease virus vaccines into wild birds, and identification of a protein cell receptor for murine noroviruses.
