World-leading scientists have called for a halt on research to create “mirror life” microbes amid concerns that the synthetic organisms would present an “unprecedented risk” to life on Earth.

The international group of Nobel laureates and other experts warn that mirror bacteria, constructed from mirror images of molecules found in nature, could become established in the environment and slip past the immune defences of natural organisms, putting humans, animals and plants at risk of lethal infections.

Many molecules for life can exist in two distinct forms, each the mirror image of the other. The DNA of all living organisms is made from “right-handed” nucleotides, while proteins, the building blocks of cells, are made from “left-handed” amino acids. Why nature works this way is unclear: life could have chosen left-handed DNA and right-handed proteins instead.

The fresh concerns over the technology are revealed in a 299-page report and a commentary in the journal Science. While enthusiastic about research on mirror molecules, the report sees substantial risks in mirror microbes and calls for a global debate on the work.

    I am NOT a religious man but I’m a strong believer that we are so eager to play God we are forgetting to ask the important questions around if we should.

    Personally speaking I think we need to pause on things like this, or AI as another example. We have proven repeatedly we lack the maturity as a species for what we are learning.

    That said, you can’t put everything back in Pandora’s box so for everyone reading this sharing my concern, YOLO and cover your head and wait for the worst.

    Edit - the biggest threat to humanity is our unyielding curiosity.
