Mirror life poses existential risk

Synthetic 'mirror' organisms — life built from molecular components with the opposite chirality to all Earth life — could be invisible to existing immune systems and ecological checks, creating a plausible pathway to uncontrollable ecological spread. A coordinated group of eminent scientists publicly called for a research pause and produced a technical report documenting the worst‑case risks and governance gaps. — If plausible, the creation of mirror life reframes biological risk governance: it demands international oversight, possible moratoria, and debate over whether some biological research should be off‑limits or tightly controlled.
