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.
Nobel Laureates have never made ridiculous statements that didn’t mesh well with scientific evidence. Kary Mullis, Nobel Laureate in Chemistry, credited with discovering PCR would never be quoted as refuting the evidence of HIV as causative in AIDS, cited in a journal article questioning the evidence, and then the journal article retracted due to it being inaccurately labeled as “Hypothesis and Theory” instead of opinion, factually inaccurate, and dangerous - oh. Oh no:

Next thing, you’ll tell me that scientists are humans that are fallible and some of them sometimes engage in ethically-questionable activities and sensationalism for profit.
There exists cases where scientists are wrong therefore my arrogance is correct. Got it :/
I’m not sure how I have come off as arrogant. But, I’m fallible just like every other human, including Nobel Laureates. I’m curious to see whether they are actually citing plausible pathogenicity or food web disruption, or if it is just sensationalism from the authors or the science communicator.
