Medusavirus, a giant virus, is more closely related to eukaryotic cells than other giant viruses are. In an exciting new study, scientists have used electron microscopy and time-course analysis to discover four different types of medusavirus particles within and outside infected amoeba cells, representing four different stages of virus maturation. Their results indicate that the medusavirus has a unique maturation process, providing new insights into the structural and behavioral diversity of giant viruses.
