Giant virus revived after more than 30,000 years

This electron microscope image provided by researchers in March 2014 shows a section of a Pithovirus particle, dark outline, inside an infected Acanthamoeba castellanii cell. The length of the particle is about 1.5 microns with a 0.5 micron diameter. Researchers have revived the virus, which is more than 30,000 years old, after finding it in the permafrost of northeast Siberia.
