Researchers built a 3D-printed, networked system of hot-spring pools controlled by an Arduino; through repeated wet-dry cycling, the setup produced lipid vesicles that encapsulated RNA, forming crude protocells and advancing a more realistic model of how life’s building blocks may have formed in Earth’s early hydrothermal fields.
A study published in the journal Nature Communications suggests that early Mars experienced sustained wet-dry cycling, which could have provided favorable conditions for the emergence of life. The researchers analyzed sedimentary rocks from Gale Crater, the landing site of NASA's Curiosity rover, and found evidence of desiccation cracks and salt pans, indicating the presence of intermittent drying and wetting cycles. These wet-dry cycles may have facilitated the synthesis of organic compounds and the formation of habitable environments on ancient Mars. The findings contribute to our understanding of the early Martian climate and its potential for supporting life.
