Scientists have warned that research into “mirror life” organisms — hypothetical life forms made up of molecules that perfectly mirror those found in regular life — should be stopped. As Nature reported last year, mirror organisms could pose risks to pretty much all existing life if unleashed. This week, researchers convened in Manchester, UK, to debate whether research into mirror life should be allowed or halted. “It is crucial to distinguish mirror-image molecular biology from hypothetical scenarios in the distant future, such as the creation of mirror-image organisms,” the piece reads. “But I think it is prudent to think about what could eventually happen, and perhaps set some tripwires for the future.”More on mirror life: Scientists Horrified by “Mirror Life” That Could Wipe Out Biology As We Know It
