Scientists have been exploring the possibility of creating “mirror life,” or organisms built on molecules that interact differently with humans. While advancements in technology may eventually make it possible to synthesize mirror bacteria, 38 experts warn that this could pose severe health risks.
The researchers express concern that mirror bacteria, which don’t exist in nature and would have little immunity to humans, could spread rapidly due to insufficient safeguards against laboratory containment failures or accidental releases. They also argue that engineering biocontainment measures would be challenging, if not impossible.
In contrast, research on mirror molecules, such as synthetic DNA or proteins, may have medical or scientific value. However, experts recommend halting research into developing mirror organisms, including bacteria, unless compelling evidence emerges that they wouldn’t pose extraordinary dangers.
The authors of the report argue that creating mirror bacteria would be a complex feat requiring significant advancements in unrelated technologies. They are urging researchers and funders to exercise caution and refrain from supporting such work until safety concerns can be addressed.
Experts warn that mirror proteins may evade the immune systems of many organisms, making them potentially serious pathogens with an unusually broad host range. The risks associated with creating mirror life warrant a global conversation and cautionary approach, according to Kate Adamala, one of the report’s authors.
