Scientists have constructed a synthetic cell from nonliving biological components that can grow, replicate DNA, and divide into daughter cells. While these engineered units are not yet self-sustaining and require constant external supplies of nutrients and ribosomes to function, they represent a significant milestone in recreating life-like processes within an artificial lipid membrane. This breakthrough provides new avenues for investigating abiogenesis, studying diseases, and developing novel materials like biofuels or drugs.
* Successful integration of DNA replication systems inside liposomes
* Achievement of cell division using protein tags to bend the membrane rather than a cytoskeleton
* Observation of early selection processes within synthetic populations

Researchers have developed a new method to reconstruct the genetic code of ancient organisms, potentially allowing them to study life forms that existed before LUCA (Last Universal Common Ancestor). This involves creating 'progenitors' – simplified genetic systems that mimic the characteristics of early life, and then evolving them in the lab to observe how complexity arises.
Researchers simulated early Earth conditions with hydrothermal vents and found that archaea thrived, suggesting life may have originated in similar 'chemical gardens' rich in hydrogen and iron.
Researchers from a Spanish laboratory observe, for the first time, the formation of protocells in an experiment simulating the conditions of the early Earth, challenging traditional views on the origin of life.
