The TWiV team explains how infectious horsepox virus – likely the ancestor of smallpox vaccines – was recovered from chemically synthesized DNA fragments.
Nels joins the TWiV team to talk about his work on genomic accordions in vaccinia virus, hepatitis B virus in a 439 year old mummy, and viral induction of energy synthesis by a long noncoding RNA.
The TWiV team reviews identification of immune biomarkers in CFS/ME patients, and how a cell nuclease controls the innate immune response to vaccinia virus infection.
The TWiV team discusses how skin scarification promotes a nonspecific immune response, and whether remaining stocks of smallpox virus should be destroyed.
Vincent and Rich meet up with Mark Challberg to talk about his scientific career studying viral DNA replication, and his transition to an NIH Program Officer.
Vincent, Alan, Rich, and Kathy review fatal avian influenza virus in harbor seals, and poxvirus deployment of genomic accordions to counter antiviral defenses.
Vincent returns to Madison, Wisconsin and meets with postdocs to discuss their science and their careers.
