Alex joins Nels and Vincent to discuss his work which demonstrates that somatic mutation rates scale with lifespan in mammals.
Nels and Vincent explain a method to calculate the mutation rate of SARS-CoV-2, and the role of a single amino acid change in spike in enhancing fitness of the delta variant and enabling it to out-compete the alpha variant.
Nels and Vincent reveal a highly conserved protein that acts as an evolvability factor, increasing mutation and the ability of bacteria to become resistant to antibiotics.
Nels and Vincent talk about how a cellular enzyme contributes to the very high mutation rate of human immunodeficiency virus type 1.
