Scientists have identified unusual virus-like entities that blur the boundary between living and non-living matter. These “giant” viruses possess massive genomes, complex structures, and even genes once thought exclusive to cellular life—yet they still depend on host cells to reproduce. The discovery challenges the traditional definition of life and offers clues about how life may have evolved on Earth. Key Facts: • Larger and more complex than typical viruses • Contain genes linked to cellular

When a giant virus infects a host cell (such as an amoeba), it creates a “viral factory” inside the host to replicate itself.If a virophage is present, it invades that same factory and uses its machinery to replicate itself instead — often sabotaging or suppressing the giant virus in the process.Famous example:The Sputnik virophage, discovered in 2008, was the first known virophage. It infects the giant Mimivirus and can weaken or destroy it, limiting its replication.Why it matters:• Virophages
