SARS-CoV-2 Genetic Variant May Be More Transmissible
Abby Olena | Nov 25, 2020
The so-called 614G mutation in the viral spike protein does not appear to cause more severe cases of COVID-19, but multiple studies indicate that it could be more contagious.

COVID-19 Research Biased Toward Only a Handful of Genes
Amanda Heidt | Nov 24, 2020
Thomas Stoeger of Northwestern University has previously studied scientists’ limited focus on certain genes. In a new study, he shows how these same behaviors extend into the science of COVID-19.
