Adamala Team Unveils 90,000-Base-Pair SpudCell as Synthetic Cell Replicates for 5 Generations
3 articles · Updated · CNN · Jul 1
Summary
Wednesday’s paper describes SpudCell, a synthetic cell assembled from nonliving chemicals that can feed, grow and divide for about five generations.
Made of 150 to 200 molecules, the prototype is still fragile: each division takes roughly 12 hours at 30C, and it must be fed E. coli ribosomes because it cannot make its own.
The cell splits by protein crowding at its membrane rather than using a natural cytoskeleton, showing life-like replication through a different mechanism from biological cells.
Researchers say that fully defined design could make SpudCell a programmable chassis for studying life’s origins and eventually for applications such as cancer therapies, carbon capture or chemical production.
The work has not yet been peer-reviewed, and scientists say SpudCell is not life and poses no current biosafety threat, though its creators want Biotic to share the platform under an open standard.
A new cell can eat, grow, and evolve. Where is the line between a complex chemical machine and a living thing?
As the recipe for synthetic life goes open-source, who decides when scientific ambition has gone too far?
Why is the creator of a new synthetic cell now warning that a related technology could unleash an 'unstoppable plague'?
Building Life from the Ground Up: SpudCells and the Future of Synthetic Biology
Overview
On July 1, 2026, Dr. Kate Adamala's team at the University of Minnesota introduced SpudCells, a groundbreaking form of synthetic life. These synthetic cells are built from nonliving components and can feed, grow, and reproduce for several generations. Scientists achieved this by constructing a cell from scratch that shows the basic hallmarks of life, marking a major shift in how we understand and create life-like systems using a bottom-up approach. SpudCells have a much smaller genome than natural cells, yet they are able to replicate, highlighting a new frontier in synthetic biology.
