Researchers warn of health risks from synthetic mirror bacteria

Researchers have raised concerns about "mirror bacteria," synthetic organisms with molecules that are the opposite of those in all known life. These bacteria could evade natural defenses, posing risks to humans, animals, and plants. Currently in early development, mirror bacteria may take over a decade to create. Scientists warn that they could cause severe infections and spread rapidly in ecosystems, potentially leading to significant harm. The researchers recommend limiting or banning research on mirror bacteria until more is known about their risks. They suggest developing detection methods and studying how these organisms interact with immune systems to mitigate potential threats.
