Mirror Life: Scientists Clash over Threat of Lab-Engineered Bacteria
A new modelling study suggests that lab‑engineered bacteria built from mirror‑image molecules would struggle to survive outside controlled environments because they require a synthetic “mirror food” supply. The researchers argue this inherent dependency limits the risk of accidental release. However, a cohort of synthetic‑biology experts counters that the analysis underestimates the potential for these organisms to evolve or acquire alternative nutrient pathways, raising bio‑security concerns. The debate underscores a growing tension between innovative biotechnology and safety oversight.
