    On a molecular level, life as we know it has a
    surprising bias. The building blocks of life — DNA,
    RNA, and proteins — have a “handedness,” like our
    left and right hands. For reasons still unclear,
    nature almost exclusively uses right-handed DNA
    and left-handed proteins. But what if science
    flipped the script?

    In labs around the world, scientists have
    tinkered with this idea, crafting mirror versions
    of life’s essential molecules. These synthetic
    creations could revolutionize therapies for
    diseases and contamination-resistant
    manufacturing. At the same time, reversing a
    molecule’s handedness could cause untold harm.

    This week, nearly 40 scientists — including two
    Nobel laureates — raised a chilling alarm. The
    creation of “mirror life” — synthetic organisms
    made of these reversed molecules — could lead to
    catastrophic consequences. Their nearly 300-page
    report, published in Science, is unequivocal:
    research on mirror microbes should stop before
    it’s too late.

    “The threat we’re talking about is
    unprecedented,” said Professor Vaughn Cooper, a
    microbiologist at the University of Pittsburgh.
    “Mirror bacteria would likely evade many human,
    animal, and plant immune system responses and in
    each case would cause lethal infections that
    would spread without check.”
