Harvard scientists just shattered one of biology’s oldest rules. We were taught: Viruses can’t make their own proteins. They hijack yours. That’s why they’re “not alive.” Except giant DNA viruses just crossed that line. Researchers found they carry a full eukaryotic-style translation complex (vIF4F). Translation machinery. Inside a virus. They can keep making proteins even under stress that shuts down normal viral replication. If a virus brings its own protein-making tools… Is it still just a parasite? For decades we’ve drawn a clean boundary: Cell = alive Virus = not alive Nature doesn’t care about our categories. Maybe viruses aren’t just evolutionary side notes. Maybe they helped build complex life. Paper in Cell 👇 cell.com/cell/fulltext/S0092… Harvard news: cellbio.hms.harvard.edu/rece…
