We did a lot of science communication in 2018. By we, I mean all the individuals who gave their time selflessly to write for this blog or record podcasts with me. Here is a summary of what we did last year. virology blog
Plasmids have been discovered that can move from cell to cell within membrane vesicles in a species of Archaea (link to paper). They provide clues about the origin of virus particles. Electron microscope analysis of the culture medium from Halobrum lacusprofundi R1S1, an Archaeal strain from Antarctica, revealed spherical particles which were subsequently shown to …

On episode #367 of the science show This Week in Virology, two Coynes join the TWiV overlords to explain their three-dimensional cell culture model of polarized intestinal for studying enterovirus infection. You can find TWiV #367 at www.microbe.tv/twiv.
The acquisition of a capsid is thought to be a key event in the evolution of viruses from the self-replicating genetic elements that existed during the pre-cellular stage on Earth. The origin of viral capsids has been obscure because their components are not similar to cellular proteins. The discovery that a viral capsid protein evolved from …
On episode #342 of the science show This Week in Virology, the TWiVniks discuss the structure of a virus that reproduces in an extreme environment, long-term consequences of Ebolavirus infection, and VirScan, a method to identify the different virus infections you have had in your lifetime.
