Nels and Vincent review evidence that a single amino acid change in the SARS-CoV-2 spike protein has driven adaptation to humans, followed by an update on the status of variants of concern.
Nels and Vincent consider evolution of antibody immunity to SARS-CoV-2, and update the situation on novel virus variants of concern with potentially altered fitness and reactivity with antibodies.
Nels and Vincent wrap up 2020 with a discussion of novel variants of SARS-CoV-2 that have emerged in the United Kingdom and South Africa, how to interpret the rapidly emerging genome sequence data and what to look for in the coming weeks as these variants spread across the globe.
Nels and Vincent discuss an opinion piece on 12 evolutionary insights into how the COVID-19 pandemic is shaping human nature, and prolonged SARS-CoV-2 reproduction in an immunosuppressed patient.
Nels and Vincent answer listener questions and discuss a newly discovered virus of amoeba with a nearly complete ORFan genome: none of the proteins encoded in the viral genome look like any other proteins.
Nels and Vincent continue their discussion of SARS-CoV-2 evolution, including understanding recurrent mutations in the viral genome, and the potential for re-emergence of the virus from an animal reservoir.
Nels and Vincent continue their discussion of SARS-CoV-2 evolution, with a report that the coronavirus proofreading enzyme stimulates RNA recombination, and debunking the conclusion that a change in the viral spike glycoprotein is associated with increased human to human transmission.
Nels and Vincent continue their discussion of SARS-CoV-2 from an evolutionary viewpoint, including function of the furin cleavage site, whether Vervet cells are an informative system, another bat isolate, and a nomenclature to assist genomic epidemiology.
Nels and Vincent continue their discussion of SARS-CoV-2 from an evolutionary viewpoint, focusing on what the genome sequences tell us about the virus.
