Story here. I find it fascinating that viruses can be infected by other viruses.
Excerpt: "Viruses are glorified scraps of genetic code that are exquisitely designed to pirate a host to reproduce: the common cold virus needs cells in the nose and respiratory tract to reproduce, before being spread with a sneeze.
“But the discovery of a giant virus that itself falls ill through infection by another virus seems to suggest they too are alive, highlighting how there is no watertight definition of what exactly scientists mean when they refer to something as ‘living’.”
