Study reveals risks of mirror bacteria in synthetic biology

A new study published in *Science* examines the risks of creating mirror bacteria, which use biomolecules with reversed chirality. Researchers found that these organisms could evade immune responses and disrupt ecosystems, raising significant health and ecological concerns. The study highlights that mirror bacteria might survive environmental challenges and resist natural predators, similar to invasive species. Their unique chirality allows them to avoid detection by immune systems, potentially leading to severe infections in humans, animals, and plants. Researchers emphasize the need for strict policies and collaboration among scientists and policymakers to manage the risks associated with synthetic mirror organisms. They argue that the dangers of creating these bacteria outweigh their potential benefits.
