An artificial cell eats, grows, and reproduces. Is it alive?
Summary
Science Friday hosts Dr. Kate Adamala to discuss the creation of the "Spud cell," a synthetic, fully defined artificial cell that can grow, replicate DNA, and reproduce. Adamala explains that this engineerable system aims to replace petrochemical manufacturing with sustainable biological factories, offering more control than natural cells like E. coli. While currently fragile and unable to evolve spontaneously, the open-source technology seeks to redefine bioengineering by building life from scratch.
