She claims to discover what made Corona circulate

The researchers isolated different strains of the Corona virus, which were identified by their genetic signatures around the world. They then placed each of
them in a microscopic cage, and tested the extent to which the strains involved attacked human cells in Petri dishes. And one of the strains was the clear
winner – the recurrence of the virus with the mutated gene that gave it more “Spike” proteins. Specifically, Spike proteins bind to ACE2 receptors that circulate on the surface of lung cells as well as blood vessels, making
these systems key targets of the Corona virus. The more proteins there are, the greater the chance that the virus will adhere to the human cell.
The longer it remains stable and stable to receptors, the greater the chance that viral particles will enter the human cell.
