We Should Worry About the Omicron Mouse Origin Theory
The news that the Omicron strain of SARS-Cov2 has mouse fingerprints all over it probably didn’t rock your world, but it maybe it should. Let’s first explain the mouse part.Wei et al claim that the molecular spectrum of mutations (i.e., the relative frequency of the...
