Interesting Fact - Viruses

An ancient virus, which was found frozen in a deep layer of the Siberian permafrost has come back to "life".

(It is thought to have lain dormant for at least 30,000 years, but after it thawed it became infectious once again.

At 1.5 micrometres in length, it is the biggest virus that has ever been found. Luckily it poses no threat to humans or animals. It attacks amoebas, the big bully.

I say "life" in quotes because of course, viruses aren't actually alive.)
