Why The Science Points to a Lab Leak
Two eminent scientists explain why the evidence points toward a laboratory origin for the covid-19 virus:
In gain-of-function research, a microbiologist can increase the lethality of a coronavirus enormously by splicing a special sequence into its genome at a prime location. Doing this leaves no trace of manipulation. But it alters the virus spike protein, rendering it easier for the virus to inject genetic material into the victim cell.
