	- 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.
