  1. It was great to see Ken discuss this extreme virus research with great enthusiasm. With all the human virus talk these days its nice to switch gears and talk about this. I still scratch my head at how a tombusvirus icosahedral capsid (closely realted to the TBSV plant virus capsid) could package a DNA instead of RNA genome such as this and be stable at pH 3.0 at elevated temperatures.  TBSV is considered a “weak” virus with critical cation-stable cites required just to be stable.  These cation sites are also apparently conserved within this virus.

    With all that aside…I’m excited to see how this story unfolds. I would also love to see Ken bring his enthusiasm and be a contributor to your show 2 or 3 times a year. He fits perfectly with you guys and its nice to mix it up with this type of virology 🙂
