I was interviewed on a podcast, Virology Unmasked, virologyunmasked.com/michael-e… with the title "Work on Important Things" which was a quote from my graduate school advisor, Howard Temin. The conversation was a nice retrospective of my career in virology and mentoring style.

I was very fortunate to collaborate with Jonatas Abrahao on this study, in which his group discovered a novel giant virus with remarkable morphology!

Few giant viruses with a tail have been characterized so far, but recent findings suggest that these structures may be more common than previously thought.

Spent most of the week at the Cold Spring Harbor Meeting on Retroviruses. This was the first big meeting I attended many decades ago as 2nd year graduate student, and returned many times since, although not in recent years. The humidity was surprisingly not terrible.

Hot springs viruses at Yellowstone National Park have ancient origins and are adapted to thermophilic hosts - Communications Biology

Analysis of the virus community associated with red algal mats in Yellowstone National Park shows it to be dominated by Megaviricetes, with resident virus lineages being of ancient origin and encoding genomic footprints of adaptation to thermophily.

Virophages are viruses that infect giant viruses, typically resulting in a lower burst size for the giant virus. In our latest preprint we report virophage-like sequences associated with insect poxviruses.

Their genomes of these elements are really interesting. This also opens up the possibility that hyperparasitic viruses are associated with a much broader range of DNA viruses than is commonly thought.

Polinton-like Viruses Associated with Entomopoxviruses Provide Insight into Replicon Evolution

Polinton-like viruses (PLVs) are a diverse group of small integrative dsDNA viruses that infect diverse eukaryotic hosts. Many PLVs are hypothesized to parasitize viruses in the phylum Nucleocytoviricota for their own propagation and spread.

'She also points out that some viruses such as Ebola and Zika don’t have a known latent phase, yet “we know people where, six months after recovery, you get transmission of #Zika, or #Ebola, or reactivation of problems . . . That means that full length RNA is there and can resume production.”

It's been a big mystery why giant viruses encode so many proteins involved in vesicular transport and cytoskeletal dynamics. This interesting paper examined a dynamin homolog and found evidence that it's involved in mitochondrial membrane remodelling during infection.

@RNA has called this the "Platinum Age of Virus Discovery"!
