Strathclyde Durham Propose Mirror Life Detector

Scientists have already built a test that could spot a life form that doesn't exist yet. On October 24, 2026, researchers from Strathclyde and Durham University unveiled the idea in Royal Society Open Science. They propose using fluorescent probes that emit circularly polarized light, the same principle behind modern 3D movie glasses. The light's left- or right-handed twist reveals a molecule's chirality, letting scientists tell ordinary cells from their mirror-image twins. Because mirror life is hypothetical, they will test the method on normal organisms first, avoiding the need to create samples. To cut false alarms they recommend using several probes that target different cell structures, creating a combined fingerprint. Experts say the chance is low, but the UK Office for Science and the UN advisory board flag the risk. Dr. Lewis MacKenzie summed it up. "We don't expect mirror life tomorrow, but if it did arise, the consequences could be severe."
