Kate Adamala's synthetic “SpudCell” replicates in lab

Researchers led by Kate Adamala at the University of Minnesota, together with bioengineer Drew Endy, have built the first synthetic cell assembled entirely from non‑living chemical components. Named SpudCell, the organism is enclosed in a tiny liposome that houses a PURE mixture of proteins, RNA and small molecules, allowing it to feed, grow, copy its genome and divide. The cell can sustain about five generations before losing functionality, with only roughly 30 % of daughter cells retaining a complete genome. While the achievement demonstrates a major step toward constructing life‑like systems, the creators stress that SpudCell does not meet the full criteria for life—it cannot repair itself, evolve independently, or maintain long‑term stability without external intervention. The findings were presented on 2 July and are slated for peer‑review submission after an initial rejection from *Cell*.

The breakthrough is expected to inform studies of early life on Earth and could eventually enable engineered micro‑factories for medicines or new materials, although substantial technical challenges remain.
