Why multipartite viruses infect plants rather than animals
Being in between living and non-living, viruses are, in general, strange. Among viruses, multipartite viruses are among the most peculiar -- their genome is not packed into one, but many, particles. Multipartite viruses primarily infect plants rather than animals. A recent paper by researchers from Tokyo Institute of Technology (Tokyo Tech) uses mathematical and computational models to explain this observation. (2019-10-01)

Immune system response to viral DNA is unique

Viruses -- lots of them -- are falling from the sky
An astonishing number of viruses are circulating around the Earth's atmosphere -- and falling from it -- according to new research from scientists in Canada, Spain and the US. The study marks the first time scientists have quantified the viruses being swept up from the Earth's surface into the free troposphere, beyond Earth's weather systems but below the stratosphere where jet airplanes fly. The viruses can be carried thousands of kilometres there before being deposited back onto the Earth's surface. (2018-02-06)

Viruses are everywhere, maybe even in space
Viruses are the most abundant and one of the least understood biological entities on Earth. They might also exist in space, but as of yet scientists have done almost no research into this possibility. Portland State University biology professor Ken Stedman and colleagues are trying to change this through their article (2018-01-18)
