Heading: Scientists Begin Journey to Create Life from Scratch in Revolutionary ‘MiniLife’ Project
Roula Khalaf, editor of FT, has handpicked her favorite story from this week’s digest. European scientists have embarked on a groundbreaking mission to create simple life forms in a laboratory setting, leveraging rapid advances in synthetic biology. Dubbed ‘MiniLife’, this €13 million project, funded by the European Research Council (ERC) and involving researchers from several universities, could be the first to meet the minimum criteria for a synthetic life system.
The ambitious goal? To initiate life from non-living chemical substances, resulting in metabolically active cells that grow, divide, and exhibit "Darwinian evolution" within six years. Led by Eörs Szathmáry, director of the Centre for the Conceptual Foundations of Science at the Parmenides Foundation Germany, the project symbolizes humanity’s longstanding dream of creating life.
John Sutherland, an expert in early life chemistry at Cambridge’s MRC Laboratory of Molecular Biology, noted the global push to "create minimal life systems." He commented, "It’s driven by our eternal desire to understand how life began on Earth and if it could also start elsewhere in the observable universe."
Unlike other life building projects focusing on known life’s building blocks—like nucleotides forming RNA—MiniLife aims to start from scratch, avoiding evolution’s products. Instead, Szathmáry explained, they "abstract from known life forms because they’re highly evolved creatures, and simplify to achieve a minimal formulation."
The MiniLife team is evaluating four potential systems, individually or combined, showcasing the crucial property of autocatakysis—reactions catalyzed by their own products. One promising candidate is the formose reaction, discovered in the 19th century, transforming simple chemicals into diverse, complex sugars when paired with formaldehyde. Researchers have observed competition among sugar compositions, analogous to biological fitness.
While aggressive, the six-year timeline hopes to demonstrate "primitive Darwinian evolution," switching between two heritable states in response to different environments. Sijbren Otto, a Groningen University professor and MiniLife member, is driven by curiosity about life’s nature and origins. Despite concerns raised about potential risks in synthetic biology—including rogue ‘mirror life’ microorganisms—Otto assures that MiniLife’s creations pose no threat outside lab conditions. Yet, the team plans to develop an ethical framework for their research, looking ahead to future implications.
Stay tuned as this revolutionary project brings us closer to understanding life’s origins and potentially, its possibilities beyond Earth.
