  • Scientists have discovered mysterious giant viruses on Greenland's ice sheet.
  • These viruses were discovered for the first time in 1981 in the ocean.
  • They usually infect the algae in the sea.
  • But this is the first time that giant viruses have been found in such a habitat.
  • They say the giant viruses may act as some sort of secret weapon and help in minimising the ice from melting.
  • Regular viruses measure 20-200 nanometres in size, whereas a typical Bacteria is 2-3 micrometres.
  • In other words, a normal virus is around 1,000 times smaller than a Bacteria.
  • But giant viruses grow to the size of 2.5 micrometres, that is bigger than most bacteria.
