For the very first time, biologists packed nonliving components into a cell-like membrane, piece by piece, and witnessed the bag of molecules start to behave like life. The lab-made synthetic cell grew, replicated its DNA, and divided, demonstrating the basic functions of a cell cycle. It’s “an impressive step,” said Jack Szostak, who studies the origins of life at the University of Chicago and…
