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.

    Did they create some organism yet?

    I believe creating life from non living parts available in nature has a great importance in proving that life could definitely have been originated like that. This would have several consequences to how we view the world.

    As for the risks, they could agree on destroying all the created life after recording and documenting the results

      What if they miss one and it multiplies out of sight. Now it’s out, forever. Impossible to undo. Because Ricky was a little hungover and spilled a drop without noticing.
