Pithovirus research. A researcher places a sample on microscope stage to observe the life cycle of Pithovirus sibericum,a species of giant virus which infects amoebas. The virus is the largest known,and was discovered in 2014 when a viable specimen was found in a 30,000-year-old ice core harvested from permafrost in Siberia,Russia. Its genome is one circular,double-stranded DNA (dsDNA) chromosome. Pithovirus undergoes its entire replication cycle in its host's cytoplasm,rather than the more typical method of taking over the host's nucleus. Photographed at Aix-Marseille University,France | |
