‘Unprecedented risk’ to life on Earth: Scientists call for halt on ‘mirror life’ microbe research

The Facts
In a report published in the journal Science on Thursday, 38 prominent scientists, including two Nobel laureates, have cautioned about the potential dangers of lab-made "mirror bacteria" — hypothetical synthetic organisms built with reversed molecular structures.
Mirror bacteria would be constructed using "left-handed" DNA instead of the "right-handed" DNA found in natural organisms. As they differ fundamentally from all known life forms, scientists claim these synthetic organisms could pose catastrophic risks to ecosystems and human health.
The Spin
Narrative A
Mirror bacteria research could lead to groundbreaking medical treatments and therapeutic applications while advancing humanity's understanding of life's fundamental principles. The technology could help develop more effective drugs and create contamination-resistant bioproduction facilities. Instead of halting its research, scientists should lay the groundwork for responsible innovation in synthetic biology and guide research in ways that prioritize safety for people, animals, and the environment.
Narrative B
We shouldn't be making mirror life. Period. Without natural predators or effective countermeasures, these synthetic organisms could cause unstoppable pandemics and irreversible environmental damage. Additionally, mirror bacteria could have an incredibly deadly impact if not safely contained or kept in check by natural competitors. Funders must withhold support for such projects as the creation of mirror bacteria threatens global ecosystems and human health.
