Scientists say they are close to building life from scratch: they have created cells that feed, grow, and multiply

Scientists claim they are nearing the creation of life from scratch, having developed artificial cells capable of feeding, growing, and reproducing. This breakthrough could pave the way for engineered organisms designed to produce medicines, food, and fuel. Researchers have spent decades attempting to create living cells in laboratories, but a team led by biologist Kate Adamala from the University of Minnesota has taken a significant step forward. They published their findings on the preprint server bioRxiv, detailing how they have transformed raw chemicals into self-sustaining life forms. The research team successfully created simple artificial cells that can consume nutrients, grow, reproduce, and even compete for resources. While these human-made cells are not fully alive, they exhibit numerous characteristics associated with life. According to Adamala, the cells are not as fast, robust, or efficient in most functions compared to natural cells, but they demonstrate that molecules can replicate behaviors previously thought exclusive to natural living cells. Named SpudCell, the artificial cell resembles a potato, a name chosen humorously by Adamala due to her Polish heritage and childhood experiences with potatoes. Once placed in laboratory flasks, the SpudCells began behaving like living organisms. They consumed molecules provided by researchers and combined them with lipid-based nutrient carriers containing essential components such as enzymes. As they fed, they expanded and within several hours were ready for replication. These synthetic cells also showed rudimentary evolutionary capabilities. Despite this progress, SpudCells are far from perfect replicas of natural life. They possess their own genes but lack the ability to form ribosomes, cellular factories responsible for protein synthesis. Some scientists remain skeptical about whether the achieved results bring them closer to creating a completely synthetic cell. Others question whether these artificial cells will ever surpass modified bacteria in terms of producing medicines, food, fuel, or other materials. Adamala believes that SpudCells might one day generate substances that natural cells cannot, such as new drugs. She emphasizes that this is just the beginning of a much larger journey toward understanding and potentially creating life from basic chemical building blocks. The implications of this research extend beyond scientific curiosity, hinting at future applications in medicine, industry, and environmental science. However, many challenges remain before such artificial cells can achieve full functionality comparable to natural ones.
