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.

    But is it not our curiosity that defines us? What separates us from machines, outside of needing to sleep, if we don’t have our curiosity, our passion for the unknown? It’s not like we can only have a little curiosity, curious enough to try a new meal but not to work towards breakthroughs that might unlock ways of bettering our lives.

    How else would we have gotten all of our vaccines without people “playing god”? I think while the garbage AI is a bit scary, it’s not the AI part that terrifies me, it’s the coldness “the economy” has towards people’s livelihoods, otherwise AI is nothing special in pushing forward or downfall as a society, it’s just highlighting something that was always there, a class conflict
