  • "They grew them in the presence of antibiotics to kill bacterial parasites and looked for cultures where the cells had a tendency to spontaneously burst (a common method of viral spread). They came up with two cultures, one from the ocean near Chile, a second from a freshwater lake near Melbourne, Australia."

  • "Although it's hard to say much about the genes that were present (since they're completely unfamiliar), a number of things were clearly not present: nothing that could contribute to the ribosome, which manufactures proteins; key parts of the DNA copying machinery; genes for components of the pathway that extracts energy from sugars and other carbon compounds; and some of the genes needed to copy DNA. In addition, a number of the virus' genes had small sequences called introns that needed to be spliced out. None of the enzymes that manage splicing were present either. These last two things indicate that the virus has to take over the cell's nucleus, or it couldn't turn its genes into proteins or copy its DNA."

"And along the way the biggest viruses got bigger. In 2011, Dr. Claverie and his colleagues set a new record with megaviruses, a type of giant virus with 1,120 genes they discovered in sea water off the coast of Chile. They then dug into the sediment below that sea water and discovered pandoravirsues, with more than twice as many genes." [AatTtd,1
