From the Fourth Symposium on Giant Virus Biology in Germany, Vincent, Rich, and Nels speak with Assaf, Stephen, and Alexandra about their careers and their work on giant viruses that infect ocean hosts: Emiliana huxleyi, Aureococcus anophagefferans, and a choanoflagellate.
The TWiV team discusses Medusavirus, isolated from a hot spring in Japan, and induction of hallmarks of neurodegeneration by recurrent herpes simplex virus 1 infection of mice.
Team TWiV cover the discovery of another giant virus from 30,000 year old Siberian permafrost, and how viral aggregation accelerates the production of new infectious viruses and increases fitness, demonstrating an Allee effect.
The TWiVniks explain how the three-dimensional structure of the giant Cafeteria roenbergensis virus suggests a new mode of assembly, and the apparent elimination of dengue fever in an Australian city by release of mosquitoes harboring Wolbachia.

From the TWiV team, human cowpox infection possibly acquired from a pet cat, and a new giant mimivirus of green algae with genes encoding enzymes of fermentation.
In the first episode for 2018, the TWiV team reviews the amazing virology stories of 2017.

- Tagged as: bootstrap, evolution, giant virus, marseillevirus, mimivirus, mRNA synthesis, Noumeavirus, nucleus, polyA, transcription, Vaccines, viral, virology, virus, viruses
No problem not being nice to Dickson in this episode, because he’s absent for a discussion of a new giant virus that replicates in the cytoplasm yet transiently accesses the nucleus to bootstrap infection.
