Surprising discovery from first large-scale analysis of biodiversity and biogeography of viruses

Viruses and bacterial viruses (known as phages) are among the most abundant life forms on the planet. Two papers published recently in Nature, March 2 and 12, 2008, analyse the geographical distribution of viral communities in modern organosedimentary structures (sedimentary features, built by the...
