Summary
Leading scientists, including Nobel laureates, are urging a halt to research on creating “mirror life” microbes, citing “unprecedented risks” to life on Earth.
Mirror microbes, built from reversed molecular structures, could evade natural immune systems, leading to uncontrollable lethal infections.
While mirror molecules hold potential for medical and industrial uses, researchers warn that mirror organisms could escape containment and resist antibiotics.
A 299-page report in Science advocates banning such research until safety can be ensured and calls for global debate on its ethical and ecological implications.
Yeah, this should probably be approached from the angle of “someone might do this, so we should do research to be prepared”.
Research ways to improve containment to reduce the chance of an accidental containment breach.
And research ways to quickly determine the weaknesses of such synthetic lifeforms if a breach happens anyways. Also to be prepared in case someone deliberately weaponizes it.
By the way, this kind of thing is why IMO if we ever do find extra terrestrial life, attempting to make any kind of physical contact or even land on the planet might end up dooming both our own species (and maybe all current complex life on Earth) as well as any complex life on that other planet. They could have basic forms of life that are entirely different from our own and completely invisible to our immune systems.
Though it would probably also have cool results in a few hundred million years, after microbial life has evolved defenses and perhaps some hybridizations.
