For first time, a cell built from scratch grows and divides (quantamagazine.org)

Article summary

Scientists have successfully created a synthetic cell from non-living components that can grow, replicate its DNA, and divide, demonstrating basic cell functions. The cell is not alive by any definition, as it requires constant deliveries of food and ribosomes to survive. This achievement is considered a significant step towards understanding the origins of life and creating new biological systems. The synthetic cell can potentially be used to produce new materials, such as biofuels and drugs, and help researchers study disease.

What commenters say

• Creating artificial life forms is a significant achievement, but it also raises concerns about potential apocalyptic outcomes.
• Editing existing living organisms to produce desired products may be more efficient than creating completely new synthetic cells.
• The development of synthetic cells could lead to breakthroughs in fields such as biofuel production and disease research, but it also poses risks of uncontrolled growth or mutation.
• The comparison of synthetic cells to brain-dead humans is not apt, as the former are not alive in the same way that the latter are.
• Understanding and recreating life from scratch could ultimately disprove religious creation myths and demonstrate that life is not unique to Earth.
• The focus on creating synthetic cells distracts from more pressing environmental issues, such as reducing carbon emissions from transportation and industry.
• The potential benefits of synthetic cells, such as custom metabolic pathways for manufacturing, outweigh the risks and make the research worthwhile.
• The development of synthetic cells could lead to the creation of non-biological self-replicating robots, which could have significant implications for various fields.
