Viruses infect every living organism on the planet, but not every habitat has been explored for their presence. The igneous ocean crust had not yet been examined for viruses, but seek and ye shall find: there are plenty of viruses under the seas. The oceanic basement is an enormous ecosystem that lies at the bottom of …

When giant viruses were discovered – with genomes much larger than any previously seen – some suggested that they had descended from a fourth domain of life (the current three are bacteria, archaea, and eukaryotes). Part of the reason for such a claim was the finding of homologs of bacterial and eukaryotic genes, including molecules involved …
