Mirror life

Science advice note: what are the main risks and opportunities associated with researching and developing ‘mirror life�, including along the pathway of development from cell components to self-replicating cells?�

Details

This note summarises an expert roundtable held in January 2025, discussing the need for a clear distinction between research to develop mirror components (individual molecules such as peptides and enzymes) and mirror organisms or cells (or any biological unit capable of self-replication), even though both are sometimes termed ‘mirror life�. 

This distinction has important implications for regulating research without stifling innovation; beneficial scientific and technological advances for therapeutics and novel materials, for example, could cease if all mirror life research was entirely banned.

»Ê¹ÚÌåÓýapp note represents the combined views of roundtable participants, and seeks to provide accessible science advice for policymakers. It is not a statement of government policy.
